Gerraty <sjg@zen.quick.com.au> + + * Redesigned export of VAR_CMD's via MAKEFLAGS. + We now simply append the variable names to .MAKEOVERRIDES, and + handle duplicate suppression and quoting in ExportMAKEFLAGS using: + ${.MAKEOVERRIDES:O:u:@v@$v=${$v:Q}@} + Apart from fixing quoting bugs in previous version, this allows us + to export vars to the environment by simply doing: + .MAKEOVERRIDES+= PATH + Merged again with NetBSD make, but the above is the only change. + + * configure.in: added + --disable-pwd-override disable $PWD overriding getcwd() + --disable-check-make-chdir disable make trying to guess + when it should automatically cd ${.CURDIR} + + * Merge with NetBSD make, changes include: + parse.c (ParseDoDependency): Spot that the syntax error is + caused by an unresolved cvs/rcs conflict and say so. + var.c: most of Var* functions now take a ctxt as 1st arg. + now does variable substituion on rhs of sysv style modifiers. + + * var.c (Var_Set): exporting of command line variables (VAR_CMD) + is now done here. We append the name='value' to .MAKEOVERRIDES + rather than directly into MAKEFLAGS as this allows a Makefile to + use .MAKEOVERRIDES= to disable this behaviour. GNU make uses a + very similar mechanism. Note that in adding name='value' to + .MAKEOVERRIDES we do the moral equivalent of: + .MAKEOVERRIDES:= ${.MAKEOVERRIDES:Nname=*} name='val' + +Fri Jun 1 14:08:02 2001 Simon J.

Gerraty <sjg@zen.quick.com.au> + + * main.c (ReadMakefile): don't set MAKEFILE if reading ".depend" + as that rather defeats the usefulness of ${MAKEFILE}. + + * main.c (MainParseArgs): append command line variable assignments + to MAKEFLAGS so that they get propagated to child make's. + Apparently this is required POSIX behaviour? Its useful anyway. + +Tue May 29 02:20:07 2001 Simon J. Gerraty <sjg@zen.quick.com.au> + + * compat.c (CompatRunCommand): don't use perror() since stdio may + cause problems in child of vfork(). + + * compat.c, main.c: Call PrintOnError() when we are going to bail. + This routine prints out the .curdir where we stopped and will also + display any vars listed in ${MAKE_PRINT_VAR_ON_ERROR}. + + * main.c: add ${.newline} to hold a "\n" - sometimes handy in + :@ expansion. + + * var.c: VarLoopExpand: ignore addSpace if a \n is present. + + * Added RCSid's for the files we've touched. + +Thu May 24 15:41:37 2001 Simon J. Gerraty <sjg@zen.quick.com.au> + + * configure.in: Thanks to some clues from mdb@juniper.net, + added autoconf magic to control setting of MACHINE, MACHINE_ARCH + as well as what ends up in _PATH_DEFSYSPATH. We now have: + + --with-machine=MACHINE explicitly set MACHINE + --with-force-machine=MACHINE set FORCE_MACHINE + --with-machine_arch=MACHINE_ARCH explicitly set MACHINE_ARCH + --with-default-sys-path=PATH:DIR:LIST use an explicit _PATH_DEFSYSPATH + --with-prefix-sys-path=PATH:DIR:LIST prefix _PATH_PREFIX_SYSPATH + --with-path-objdirprefix=PATH override _PATH_OBJDIRPREFIX + + If _PATH_OBJDIRPREFIX is set to "no" we won't define it. + + * makefile: added a pathetically simple makefile to drive + bootstrapping. Running configure by hand is more useful. + + * Makefile.in: added MAKE_VERSION, and reworked things to be less + dependent on NetBSD bsd.*.mk + + * pathnames.h: allow NO_PATH_OBJDIRPREFIX to stop us defining + _PATH_OBJDIRPREFIX for those that don't want a default. + construct _PATH_DEFSYSPATH from the info we get from configure. + + * main.c: allow for no _PATH_OBJDIRPREFIX, set ${MAKE_VERSION} + if MAKE_VERSION is defined. + + * compat.c: when we bail, print out the .CURDIR we were in. + +Sat May 12 00:34:12 2001 Simon J.

The basic idea behind PMake is that, for +any given system, be it a program or a document or whatever, there +will be some files that depend on the state of other files (on when +they were last modified). PMake takes these dependencies, which you +must specify, and uses them to build whatever it is you want it to +build. +.LP +PMake is almost fully-compatible with Make, with which you may already +be familiar. PMake's most important feature is its ability to run +several different jobs at once, making the creation of systems +considerably faster. It also has a great deal more functionality than +Make. Throughout the text, whenever something is mentioned that is an +important difference between PMake and Make (i.e. something that will +cause a makefile to fail if you don't do something about it), or is +simply important, it will be flagged with a little sign in the left +margin, like this: +.No +.LP +This tutorial is divided into three main sections corresponding to basic, +intermediate and advanced PMake usage. If you already know Make well, +you will only need to skim chapter 2 (there are some aspects of +PMake that I consider basic to its use that didn't exist in Make). +Things in chapter 3 make life much easier, while those in chapter 4 +are strictly for those who know what they are doing. Chapter 5 has +definitions for the jargon I use and chapter 6 contains possible +solutions to the problems presented throughout the tutorial. +.xH 1 The Basics of PMake +.LP +PMake takes as input a file that tells a) which files depend on which +other files to be complete and b) what to do about files that are +``out-of-date.'' This file is known as a ``makefile'' and is usually +.Ix 0 def makefile +kept in the top-most directory of the system to be built. While you +can call the makefile anything you want, PMake will look for +.CW Makefile +and +.CW makefile +(in that order) in the current directory if you don't tell it +otherwise. +.Ix 0 def makefile default +To specify a different makefile, use the +.B \-f +flag (e.g. +.CW "pmake -f program.mk" ''). `` +.Ix 0 ref flags -f +.Ix 0 ref makefile other +.LP +A makefile has four different types of lines in it: +.RS +.IP \(bu 2 +File dependency specifications +.IP \(bu 2 +Creation commands +.IP \(bu 2 +Variable assignments +.IP \(bu 2 +Comments, include statements and conditional directives +.RE +.LP +Any line may be continued over multiple lines by ending it with a +backslash. +.Ix 0 def "continuation line" +The backslash, following newline and any initial whitespace +on the following line are compressed into a single space before the +input line is examined by PMake. +.xH 2 Dependency Lines +.LP +As mentioned in the introduction, in any system, there are +dependencies between the files that make up the system. For instance, +in a program made up of several C source files and one header file, +the C files will need to be re-compiled should the header file be +changed. For a document of several chapters and one macro file, the +chapters will need to be reprocessed if any of the macros changes. +.Ix 0 def "dependency" +These are dependencies and are specified by means of dependency lines in +the makefile. +.LP +.Ix 0 def "dependency line" +On a dependency line, there are targets and sources, separated by a +one- or two-character operator. +The targets ``depend'' on the sources and are usually created from +them. +.Ix 0 def target +.Ix 0 def source +.Ix 0 ref operator +Any number of targets and sources may be specified on a dependency line. +All the targets in the line are made to depend on all the sources. +Targets and sources need not be actual files, but every source must be +either an actual file or another target in the makefile. +If you run out of room, use a backslash at the end of the line to continue onto +the next one. +.LP +Any file may be a target and any file may be a source, but the +relationship between the two (or however many) is determined by the +``operator'' that separates them. +.Ix 0 def operator +Three types of operators exist: one specifies that the datedness of a +target is determined by the state of its sources, while another +specifies other files (the sources) that need to be dealt with before +the target can be re-created. The third operator is very similar to +the first, with the additional condition that the target is +out-of-date if it has no sources. These operations are represented by +the colon, the exclamation point and the double-colon, respectively, and are +mutually exclusive. Their exact semantics are as follows: +.IP ":" +.Ix 0 def operator colon +.Ix 0 def : +If a colon is used, a target on the line is considered to be +``out-of-date'' (and in need of creation) if +.RS +.IP \(bu 2 +any of the sources has been modified more recently than the target, or +.IP \(bu 2 +the target doesn't exist. +.RE +.Ix 0 def out-of-date +.IP "\&" +Under this operation, steps will be taken to re-create the target only +if it is found to be out-of-date by using these two rules. +.IP "!" +.Ix 0 def operator force +.Ix 0 def ! +If an exclamation point is used, the target will always be re-created, +but this will not happen until all of its sources have been examined +and re-created, if necessary. +.IP "::" +.Ix 0 def operator double-colon +.Ix 0 def :: +If a double-colon is used, a target is out-of-date if: +.RS +.IP \(bu 2 +any of the sources has been modified more recently than the target, or +.IP \(bu 2 +the target doesn't exist, or +.IP \(bu 2 +the target has no sources. +.RE +.IP "\&" +If the target is out-of-date according to these rules, it will be re-created. +This operator also does something else to the targets, but I'll go +into that in the next section (``Shell Commands''). +.LP +Enough words, now for an example. Take that C program I mentioned +earlier. Say there are three C files +.CW a.c , ( +.CW b.c +and +.CW c.c ) +each of which +includes the file +.CW defs.h . +The dependencies between the files could then be expressed as follows: +.DS +program : a.o b.o c.o +a.o b.o c.o : defs.h +a.o : a.c +b.o : b.c +c.o : c.c +.DE +.LP +You may be wondering at this point, where +.CW a.o , +.CW b.o +and +.CW c.o +came in and why +.I they +depend on +.CW defs.h +and the C files don't. The reason is quite simple: +.CW program +cannot be made by linking together .c files \*- it must be +made from .o files. Likewise, if you change +.CW defs.h , +it isn't the .c files that need to be re-created, it's the .o files. +If you think of dependencies in these terms \*- which files (targets) +need to be created from which files (sources) \*- you should have no problems. +.LP +An important thing to notice about the above example, is that all the +\&.o files appear as targets on more than one line. This is perfectly +all right: the target is made to depend on all the sources mentioned +on all the dependency lines. E.g. +.CW a.o +depends on both +.CW defs.h +and +.CW a.c . +.Ix 0 ref dependency +.No +.LP +The order of the dependency lines in the makefile is +important: the first target on the first dependency line in the +makefile will be the one that gets made if you don't say otherwise. +That's why +.CW program +comes first in the example makefile, above. +.LP +Both targets and sources may contain the standard C-Shell wildcard +characters +.CW { , ( +.CW } , +.CW * , +.CW ? , +.CW [ , +and +.CW ] ), +but the non-curly-brace ones may only appear in the final component +(the file portion) of the target or source. The characters mean the +following things: +.IP \fB{}\fP +These enclose a comma-separated list of options and cause the pattern +to be expanded once for each element of the list. Each expansion +contains a different element. For example, +.CW src/{whiffle,beep,fish}.c +expands to the three words +.CW src/whiffle.c , +.CW src/beep.c , +and +.CW src/fish.c . +These braces may be nested and, unlike the other wildcard characters, +the resulting words need not be actual files. All other wildcard +characters are expanded using the files that exist when PMake is +started. +.IP \fB*\fP +This matches zero or more characters of any sort. +.CW src/*.c +will expand to the same three words as above as long as +.CW src +contains those three files (and no other files that end in +.CW .c ). +.IP \fB?\fP +Matches any single character. +.IP \fB[]\fP +This is known as a character class and contains either a list of +single characters, or a series of character ranges +.CW a-z , ( +for example means all characters between a and z), or both. It matches +any single character contained in the list. E.g. +.CW [A-Za-z] +will match all letters, while +.CW [0123456789] +will match all numbers. +.xH 2 Shell Commands +.LP +``Isn't that nice,'' you say to yourself, ``but how are files +actually `re-created,' as he likes to spell it?'' +The re-creation is accomplished by commands you place in the makefile. +These commands are passed to the Bourne shell (better known as +``/bin/sh'') to be executed and are +.Ix 0 ref shell +.Ix 0 ref re-creation +.Ix 0 ref update +expected to do what's necessary to update the target file (PMake +doesn't actually check to see if the target was created. It just +assumes it's there). +.Ix 0 ref target +.LP +Shell commands in a makefile look a lot like shell commands you would +type at a terminal, with one important exception: each command in a +makefile +.I must +be preceded by at least one tab. +.LP +Each target has associated with it a shell script made up of +one or more of these shell commands. The creation script for a target +should immediately follow the dependency line for that target. While +any given target may appear on more than one dependency line, only one +of these dependency lines may be followed by a creation script, unless +the `::' operator was used on the dependency line. +.Ix 0 ref operator double-colon +.Ix 0 ref :: +.No +.LP +If the double-colon was used, each dependency line for the target +may be followed by a shell script. That script will only be executed +if the target on the associated dependency line is out-of-date with +respect to the sources on that line, according to the rules I gave +earlier. +I'll give you a good example of this later on. +.LP +To expand on the earlier makefile, you might add commands as follows: +.DS +program : a.o b.o c.o + cc a.o b.o c.o \-o program +a.o b.o c.o : defs.h +a.o : a.c + cc \-c a.c +b.o : b.c + cc \-c b.c +c.o : c.c + cc \-c c.c +.DE +.LP +Something you should remember when writing a makefile is, the +commands will be executed if the +.I target +on the dependency line is out-of-date, not the sources. +.Ix 0 ref target +.Ix 0 ref source +.Ix 0 ref out-of-date +In this example, the command +.CW "cc \-c a.c" '' `` +will be executed if +.CW a.o +is out-of-date. Because of the `:' operator, +.Ix 0 ref : +.Ix 0 ref operator colon +this means that should +.CW a.c +.I or +.CW defs.h +have been modified more recently than +.CW a.o , +the command will be executed +.CW a.o "\&" ( +will be considered out-of-date). +.Ix 0 ref out-of-date +.LP +Remember how I said the only difference between a makefile shell +command and a regular shell command was the leading tab? I lied. There +is another way in which makefile commands differ from regular ones. +The first two characters after the initial whitespace are treated +specially. +If they are any combination of `@' and `\-', they cause PMake to do +different things. +.LP +In most cases, shell commands are printed before they're +actually executed. This is to keep you informed of what's going on. If +an `@' appears, however, this echoing is suppressed. In the case of an +.CW echo +command, say +.CW "echo Linking index" ,'' `` +it would be +rather silly to see +.DS +echo Linking index +Linking index +.DE +.LP +so PMake allows you to place an `@' before the command +.CW "@echo Linking index" '') (`` +to prevent the command from being printed. +.LP +The other special character is the `\-'. In case you didn't know, +shell commands finish with a certain ``exit status.'' This status is +made available by the operating system to whatever program invoked the +command. Normally this status will be 0 if everything went ok and +non-zero if something went wrong. For this reason, PMake will consider +an error to have occurred if one of the shells it invokes returns a non-zero +status. When it detects an error, PMake's usual action is to abort +whatever it's doing and exit with a non-zero status itself (any other +targets that were being created will continue being made, but nothing +new will be started. PMake will exit after the last job finishes). +This behavior can be altered, however, by placing a `\-' at the front +of a command +.CW "\-mv index index.old" ''), (`` +certain command-line arguments, +or doing other things, to be detailed later. In such +a case, the non-zero status is simply ignored and PMake keeps chugging +along. +.No +.LP +Because all the commands are given to a single shell to execute, such +things as setting shell variables, changing directories, etc., last +beyond the command in which they are found. This also allows shell +compound commands (like +.CW for +loops) to be entered in a natural manner. +Since this could cause problems for some makefiles that depend on +each command being executed by a single shell, PMake has a +.B \-B +.Ix 0 ref compatibility +.Ix 0 ref flags -B +flag (it stands for backwards-compatible) that forces each command to +be given to a separate shell. It also does several other things, all +of which I discourage since they are now old-fashioned.\|.\|.\|. +.No +.LP +A target's shell script is fed to the shell on its (the shell's) input stream. +This means that any commands, such as +.CW ci +that need to get input from the terminal won't work right \*- they'll +get the shell's input, something they probably won't find to their +liking. A simple way around this is to give a command like this: +.DS +ci $(SRCS) < /dev/tty +.DE +This would force the program's input to come from the terminal. If you +can't do this for some reason, your only other alternative is to use +PMake in its fullest compatibility mode. See +.B Compatibility +in chapter 4. +.Ix 0 ref compatibility +.LP +.xH 2 Variables +.LP +PMake, like Make before it, has the ability to save text in variables +to be recalled later at your convenience. Variables in PMake are used +much like variables in the shell and, by tradition, consist of +all upper-case letters (you don't +.I have +to use all upper-case letters. +In fact there's nothing to stop you from calling a variable +.CW @^&$%$ . +Just tradition). Variables are assigned-to using lines of the form +.Ix 0 def variable assignment +.DS +VARIABLE = value +.DE +.Ix 0 def variable assignment +appended-to by +.DS +VARIABLE += value +.DE +.Ix 0 def variable appending +.Ix 0 def variable assignment appended +.Ix 0 def += +conditionally assigned-to (if the variable isn't already defined) by +.DS +VARIABLE ?= value +.DE +.Ix 0 def variable assignment conditional +.Ix 0 def ?= +and assigned-to with expansion (i.e. the value is expanded (see below) +before being assigned to the variable\*-useful for placing a value at +the beginning of a variable, or other things) by +.DS +VARIABLE := value +.DE +.Ix 0 def variable assignment expanded +.Ix 0 def := +.LP +Any whitespace before +.I value +is stripped off. When appending, a space is placed between the old +value and the stuff being appended. +.LP +The final way a variable may be assigned to is using +.DS +VARIABLE != shell-command +.DE +.Ix 0 def variable assignment shell-output +.Ix 0 def != +In this case, +.I shell-command +has all its variables expanded (see below) and is passed off to a +shell to execute. The output of the shell is then placed in the +variable. Any newlines (other than the final one) are replaced by +spaces before the assignment is made. This is typically used to find +the current directory via a line like: +.DS +CWD != pwd +.DE +.LP +.B Note: +this is intended to be used to execute commands that produce small amounts +of output (e.g. ``pwd''). The implementation is less than intelligent and will +likely freeze if you execute something that produces thousands of +bytes of output (8 Kb is the limit on many UNIX systems). +.LP +The value of a variable may be retrieved by enclosing the variable +name in parentheses or curly braces and preceding the whole thing +with a dollar sign. +.LP +For example, to set the variable CFLAGS to the string +.CW "\-I/sprite/src/lib/libc \-O" ,'' `` +you would place a line +.DS +CFLAGS = \-I/sprite/src/lib/libc \-O +.DE +in the makefile and use the word +.CW "$(CFLAGS)" +wherever you would like the string +.CW "\-I/sprite/src/lib/libc \-O" +to appear. This is called variable expansion. +.Ix 0 def variable expansion +.No +.LP +Unlike Make, PMake will not expand a variable unless it knows +the variable exists. E.g. if you have a +.CW "${i}" +in a shell command and you have not assigned a value to the variable +.CW i +(the empty string is considered a value, by the way), where Make would have +substituted the empty string, PMake will leave the +.CW "${i}" +alone. +To keep PMake from substituting for a variable it knows, precede the +dollar sign with another dollar sign. +(e.g. to pass +.CW "${HOME}" +to the shell, use +.CW "$${HOME}" ). +This causes PMake, in effect, to expand the +.CW $ +macro, which expands to a single +.CW $ . +For compatibility, Make's style of variable expansion will be used +if you invoke PMake with any of the compatibility flags (\c +.B \-V , +.B \-B +or +.B \-M . +The +.B \-V +flag alters just the variable expansion). +.Ix 0 ref flags -V +.Ix 0 ref flags -B +.Ix 0 ref flags -M +.Ix 0 ref compatibility +.LP +.Ix 0 ref variable expansion +There are two different times at which variable expansion occurs: +When parsing a dependency line, the expansion occurs immediately +upon reading the line. If any variable used on a dependency line is +undefined, PMake will print a message and exit. +Variables in shell commands are expanded when the command is +executed. +Variables used inside another variable are expanded whenever the outer +variable is expanded (the expansion of an inner variable has no effect +on the outer variable. I.e. if the outer variable is used on a dependency +line and in a shell command, and the inner variable changes value +between when the dependency line is read and the shell command is +executed, two different values will be substituted for the outer +variable). +.Ix 0 def variable types +.LP +Variables come in four flavors, though they are all expanded the same +and all look about the same. They are (in order of expanding scope): +.RS +.IP \(bu 2 +Local variables. +.Ix 0 ref variable local +.IP \(bu 2 +Command-line variables. +.Ix 0 ref variable command-line +.IP \(bu 2 +Global variables. +.Ix 0 ref variable global +.IP \(bu 2 +Environment variables. +.Ix 0 ref variable environment +.RE +.LP +The classification of variables doesn't matter much, except that the +classes are searched from the top (local) to the bottom (environment) +when looking up a variable. The first one found wins. +.xH 3 Local Variables +.LP +.Ix 0 def variable local +Each target can have as many as seven local variables. These are +variables that are only ``visible'' within that target's shell script +and contain such things as the target's name, all of its sources (from +all its dependency lines), those sources that were out-of-date, etc. +Four local variables are defined for all targets. They are: +.RS +.IP ".TARGET" +.Ix 0 def variable local .TARGET +.Ix 0 def .TARGET +The name of the target. +.IP ".OODATE" +.Ix 0 def variable local .OODATE +.Ix 0 def .OODATE +The list of the sources for the target that were considered out-of-date. +The order in the list is not guaranteed to be the same as the order in +which the dependencies were given. +.IP ".ALLSRC" +.Ix 0 def variable local .ALLSRC +.Ix 0 def .ALLSRC +The list of all sources for this target in the order in which they +were given. +.IP ".PREFIX" +.Ix 0 def variable local .PREFIX +.Ix 0 def .PREFIX +The target without its suffix and without any leading path. E.g. for +the target +.CW ../../lib/compat/fsRead.c , +this variable would contain +.CW fsRead . +.RE +.LP +Three other local variables are set only for certain targets under +special circumstances. These are the ``.IMPSRC,'' +.Ix 0 ref variable local .IMPSRC +.Ix 0 ref .IMPSRC +``.ARCHIVE,'' +.Ix 0 ref variable local .ARCHIVE +.Ix 0 ref .ARCHIVE +and ``.MEMBER'' +.Ix 0 ref variable local .MEMBER +.Ix 0 ref .MEMBER +variables. When they are set and how they are used is described later. +.LP +Four of these variables may be used in sources as well as in shell +scripts. +.Ix 0 def "dynamic source" +.Ix 0 def source dynamic +These are ``.TARGET'', ``.PREFIX'', ``.ARCHIVE'' and ``.MEMBER''. The +variables in the sources are expanded once for each target on the +dependency line, providing what is known as a ``dynamic source,'' +.Rd 0 +allowing you to specify several dependency lines at once. For example, +.DS +$(OBJS) : $(.PREFIX).c +.DE +will create a dependency between each object file and its +corresponding C source file. +.xH 3 Command-line Variables +.LP +.Ix 0 def variable command-line +Command-line variables are set when PMake is first invoked by giving a +variable assignment as one of the arguments. For example, +.DS +pmake "CFLAGS = -I/sprite/src/lib/libc -O" +.DE +would make +.CW CFLAGS +be a command-line variable with the given value. Any assignments to +.CW CFLAGS +in the makefile will have no effect, because once it +is set, there is (almost) nothing you can do to change a command-line +variable (the search order, you see). Command-line variables may be +set using any of the four assignment operators, though only +.CW = +and +.CW ?= +behave as you would expect them to, mostly because assignments to +command-line variables are performed before the makefile is read, thus +the values set in the makefile are unavailable at the time. +.CW += +.Ix 0 ref += +.Ix 0 ref variable assignment appended +is the same as +.CW = , +because the old value of the variable is sought only in the scope in +which the assignment is taking place (for reasons of efficiency that I +won't get into here). +.CW := +and +.CW ?= +.Ix 0 ref := +.Ix 0 ref ?= +.Ix 0 ref variable assignment expanded +.Ix 0 ref variable assignment conditional +will work if the only variables used are in the environment. +.CW != +is sort of pointless to use from the command line, since the same +effect can no doubt be accomplished using the shell's own command +substitution mechanisms (backquotes and all that). +.xH 3 Global Variables +.LP +.Ix 0 def variable global +Global variables are those set or appended-to in the makefile. +There are two classes of global variables: those you set and those PMake sets. +As I said before, the ones you set can have any name you want them to have, +except they may not contain a colon or an exclamation point. +The variables PMake sets (almost) always begin with a +period and always contain upper-case letters, only. The variables are +as follows: +.RS +.IP .PMAKE +.Ix 0 def variable global .PMAKE +.Ix 0 def .PMAKE +.Ix 0 def variable global MAKE +.Ix 0 def MAKE +The name by which PMake was invoked is stored in this variable. For +compatibility, the name is also stored in the MAKE variable. +.IP .MAKEFLAGS +.Ix 0 def variable global .MAKEFLAGS +.Ix 0 def .MAKEFLAGS variable +.Ix 0 def variable global MFLAGS +.Ix 0 def MFLAGS +All the relevant flags with which PMake was invoked. This does not +include such things as +.B \-f +or variable assignments. Again for compatibility, this value is stored +in the MFLAGS variable as well. +.RE +.LP +Two other variables, ``.INCLUDES'' and ``.LIBS,'' are covered in the +section on special targets in chapter 3. +.Ix 0 ref variable global .INCLUDES +.Ix 0 ref variable global .LIBS +.LP +Global variables may be deleted using lines of the form: +.Ix 0 def #undef +.Ix 0 def variable deletion +.DS +#undef \fIvariable\fP +.DE +The +.CW # ' ` +must be the first character on the line. Note that this may only be +done on global variables. +.xH 3 Environment Variables +.LP +.Ix 0 def variable environment +Environment variables are passed by the shell that invoked PMake and +are given by PMake to each shell it invokes. They are expanded like +any other variable, but they cannot be altered in any way. +.LP +One special environment variable, +.CW PMAKE , +.Ix 0 def variable environment PMAKE +is examined by PMake for command-line flags, variable assignments, +etc., it should always use. This variable is examined before the +actual arguments to PMake are. In addition, all flags given to PMake, +either through the +.CW PMAKE +variable or on the command line, are placed in this environment +variable and exported to each shell PMake executes. Thus recursive +invocations of PMake automatically receive the same flags as the +top-most one. +.LP +Using all these variables, you can compress the sample makefile even more: +.DS +OBJS = a.o b.o c.o +program : $(OBJS) + cc $(.ALLSRC) \-o $(.TARGET) +$(OBJS) : defs.h +a.o : a.c + cc \-c a.c +b.o : b.c + cc \-c b.c +c.o : c.c + cc \-c c.c +.DE +.Ix 0 ref variable local .ALLSRC +.Ix 0 ref .ALLSRC +.Ix 0 ref variable local .TARGET +.Ix 0 ref .TARGET +.Rd 3 +.xH 2 Comments +.LP +.Ix 0 def comments +Comments in a makefile start with a `#' character and extend to the +end of the line. They may appear +anywhere you want them, except in a shell command (though the shell +will treat it as a comment, too). If, for some reason, you need to use the `#' +in a variable or on a dependency line, put a backslash in front of it. +PMake will compress the two into a single `#' (Note: this isn't true +if PMake is operating in full-compatibility mode). +.Ix 0 ref flags -M +.Ix 0 ref compatibility +.xH 2 Parallelism +.No +.LP +PMake was specifically designed to re-create several targets at once, +when possible. You do not have to do anything special to cause this to +happen (unless PMake was configured to not act in parallel, in which +case you will have to make use of the +.B \-L +and +.B \-J +flags (see below)), +.Ix 0 ref flags -L +.Ix 0 ref flags -J +but you do have to be careful at times. +.LP +There are several problems you are likely to encounter. One is +that some makefiles (and programs) are written in such a way that it is +impossible for two targets to be made at once. The program +.CW xstr , +for example, +always modifies the files +.CW strings +and +.CW x.c . +There is no way to change it. Thus you cannot run two of them at once +without something being trashed. Similarly, if you have commands +in the makefile that always send output to the same file, you will not +be able to make more than one target at once unless you change the +file you use. You can, for instance, add a +.CW $$$$ +to the end of the file name to tack on the process ID of the shell +executing the command (each +.CW $$ +expands to a single +.CW $ , +thus giving you the shell variable +.CW $$ ). +Since only one shell is used for all the +commands, you'll get the same file name for each command in the +script. +.LP +The other problem comes from improperly-specified dependencies that +worked in Make because of its sequential, depth-first way of examining +them. While I don't want to go into depth on how PMake +works (look in chapter 4 if you're interested), I will warn you that +files in two different ``levels'' of the dependency tree may be +examined in a different order in PMake than they were in Make. For +example, given the makefile +.DS +a : b c +b : d +.DE +PMake will examine the targets in the order +.CW c , +.CW d , +.CW b , +.CW a . +If the makefile's author expected PMake to abort before making +.CW c +if an error occurred while making +.CW b , +or if +.CW b +needed to exist before +.CW c +was made, +s/he will be sorely disappointed. The dependencies are +incomplete, since in both these cases, +.CW c +would depend on +.CW b . +So watch out. +.LP +Another problem you may face is that, while PMake is set up to handle the +output from multiple jobs in a graceful fashion, the same is not so for input. +It has no way to regulate input to different jobs, +so if you use the redirection from +.CW /dev/tty +I mentioned earlier, you must be careful not to run two of the jobs at once. +.xH 2 Writing and Debugging a Makefile +.LP +Now you know most of what's in a makefile, what do you do next? There +are two choices: (1) use one of the uncommonly-available makefile +generators or (2) write your own makefile (I leave out the third choice of +ignoring PMake and doing everything by hand as being beyond the bounds +of common sense). +.LP +When faced with the writing of a makefile, it is usually best to start +from first principles: just what +.I are +you trying to do? What do you want the makefile finally to produce? +.LP +To begin with a somewhat traditional example, let's say you need to +write a makefile to create a program, +.CW expr , +that takes standard infix expressions and converts them to prefix form (for +no readily apparent reason). You've got three source files, in C, that +make up the program: +.CW main.c , +.CW parse.c , +and +.CW output.c . +Harking back to my pithy advice about dependency lines, you write the +first line of the file: +.DS +expr : main.o parse.o output.o +.DE +because you remember +.CW expr +is made from +.CW .o +files, not +.CW .c +files. Similarly for the +.CW .o +files you produce the lines: +.DS +main.o : main.c +parse.o : parse.c +output.o : output.c +main.o parse.o output.o : defs.h +.DE +.LP +Great. You've now got the dependencies specified. What you need now is +commands. These commands, remember, must produce the target on the +dependency line, usually by using the sources you've listed. +You remember about local variables? Good, so it should come +to you as no surprise when you write +.DS +expr : main.o parse.o output.o + cc -o $(.TARGET) $(.ALLSRC) +.DE +Why use the variables? If your program grows to produce postfix +expressions too (which, of course, requires a name change or two), it +is one fewer place you have to change the file. You cannot do this for +the object files, however, because they depend on their corresponding +source files +.I and +.CW defs.h , +thus if you said +.DS + cc -c $(.ALLSRC) +.DE +you'd get (for +.CW main.o ): +.DS + cc -c main.c defs.h +.DE +which is wrong.

In answering this, two flags will serve you well: +.CW "-d m" '' `` +.Ix 0 ref flags -d +and +.CW "-p 2" .'' `` +.Ix 0 ref flags -p +The first causes PMake to tell you as it examines each target in the +makefile and indicate why it is deciding whatever it is deciding.

PMake has two ways of doing this, one of which +provides for much cleaner output and a clear separation between the +output of different jobs, the other of which provides a more immediate +response so one can tell what is really happening. The former is done +by notifying you when the creation of a target starts, capturing the +output and transferring it to the screen all at once when the job +finishes.

Good. That's just what it is. +However, the ways I've described have been inelegant, at best, and +painful, at worst. +This chapter contains things that make the +writing of makefiles easier and the makefiles themselves shorter and +easier to modify (and, occasionally, simpler). In this chapter, I +assume you are somewhat more +familiar with Sprite (or UNIX, if that's what you're using) than I did +in chapter 2, just so you're on your toes. +So without further ado... +.xH 2 Transformation Rules +.LP +As you know, a file's name consists of two parts: a base name, which +gives some hint as to the contents of the file, and a suffix, which +usually indicates the format of the file. +Over the years, as +.UX +has developed, +naming conventions, with regard to suffixes, have also developed that have +become almost as incontrovertible as Law. E.g. a file ending in +.CW .c +is assumed to contain C source code; one with a +.CW .o +suffix is assumed to be a compiled, relocatable object file that may +be linked into any program; a file with a +.CW .ms +suffix is usually a text file to be processed by Troff with the \-ms +macro package, and so on. +One of the best aspects of both Make and PMake comes from their +understanding of how the suffix of a file pertains to its contents and +their ability to do things with a file based solely on its suffix. This +ability comes from something known as a transformation rule. A +transformation rule specifies how to change a file with one suffix +into a file with another suffix. +.LP +A transformation rule looks much like a dependency line, except the +target is made of two known suffixes stuck together. Suffixes are made +known to PMake by placing them as sources on a dependency line whose +target is the special target +.CW .SUFFIXES . +E.g. +.DS +\&.SUFFIXES : .o .c +\&.c.o : + $(CC) $(CFLAGS) -c $(.IMPSRC) +.DE +The creation script attached to the target is used to transform a file with +the first suffix (in this case, +.CW .c ) +into a file with the second suffix (here, +.CW .o ). +In addition, the target inherits whatever attributes have been applied +to the transformation rule. +The simple rule given above says that to transform a C source file +into an object file, you compile it using +.CW cc +with the +.CW \-c +flag. +This rule is taken straight from the system makefile. Many +transformation rules (and suffixes) are defined there, and I refer you +to it for more examples (type +.CW "pmake -h" '' `` +to find out where it is). +.LP +There are several things to note about the transformation rule given +above: +.RS +.IP 1) +The +.CW .IMPSRC +variable. +.Ix 0 def variable local .IMPSRC +.Ix 0 def .IMPSRC +This variable is set to the ``implied source'' (the file from which +the target is being created; the one with the first suffix), which, in this +case, is the .c file. +.IP 2) +The +.CW CFLAGS +variable. Almost all of the transformation rules in the system +makefile are set up using variables that you can alter in your +makefile to tailor the rule to your needs. In this case, if you want +all your C files to be compiled with the +.B \-g +flag, to provide information for +.CW dbx , +you would set the +.CW CFLAGS +variable to contain +.CW -g +.CW "CFLAGS = -g" '') (`` +and PMake would take care of the rest. +.RE +.LP +To give you a quick example, the makefile in 2.3.4 +.Rm 3 2.3.4 +could be changed to this: +.DS +OBJS = a.o b.o c.o +program : $(OBJS) + $(CC) -o $(.TARGET) $(.ALLSRC) +$(OBJS) : defs.h +.DE +The transformation rule I gave above takes the place of the 6 lines\** +.FS +This is also somewhat cleaner, I think, than the dynamic source +solution presented in 2.6 +.FE +.Rm 4 2.6 +.DS +a.o : a.c + cc -c a.c +b.o : b.c + cc -c b.c +c.o : c.c + cc -c c.c +.DE +.LP +Now you may be wondering about the dependency between the +.CW .o +and +.CW .c +files \*- it's not mentioned anywhere in the new makefile. This is +because it isn't needed: one of the effects of applying a +transformation rule is the target comes to depend on the implied +source. That's why it's called the implied +.I source . +.LP +For a more detailed example. Say you have a makefile like this: +.DS +a.out : a.o b.o + $(CC) $(.ALLSRC) +.DE +and a directory set up like this: +.DS +total 4 +-rw-rw-r-- 1 deboor 34 Sep 7 00:43 Makefile +-rw-rw-r-- 1 deboor 119 Oct 3 19:39 a.c +-rw-rw-r-- 1 deboor 201 Sep 7 00:43 a.o +-rw-rw-r-- 1 deboor 69 Sep 7 00:43 b.c +.DE +While just typing +.CW pmake '' `` +will do the right thing, it's much more informative to type +.CW "pmake -d s" ''. `` +This will show you what PMake is up to as it processes the files. In +this case, PMake prints the following: +.DS +Suff_FindDeps (a.out) + using existing source a.o + applying .o -> .out to "a.o" +Suff_FindDeps (a.o) + trying a.c...got it + applying .c -> .o to "a.c" +Suff_FindDeps (b.o) + trying b.c...got it + applying .c -> .o to "b.c" +Suff_FindDeps (a.c) + trying a.y...not there + trying a.l...not there + trying a.c,v...not there + trying a.y,v...not there + trying a.l,v...not there +Suff_FindDeps (b.c) + trying b.y...not there + trying b.l...not there + trying b.c,v...not there + trying b.y,v...not there + trying b.l,v...not there +--- a.o --- +cc -c a.c +--- b.o --- +cc -c b.c +--- a.out --- +cc a.o b.o +.DE +.LP +.CW Suff_FindDeps +is the name of a function in PMake that is called to check for implied +sources for a target using transformation rules. +The transformations it tries are, naturally +enough, limited to the ones that have been defined (a transformation +may be defined multiple times, by the way, but only the most recent +one will be used). You will notice, however, that there is a definite +order to the suffixes that are tried. This order is set by the +relative positions of the suffixes on the +.CW .SUFFIXES +line \*- the earlier a suffix appears, the earlier it is checked as +the source of a transformation. Once a suffix has been defined, the +only way to change its position in the pecking order is to remove all +the suffixes (by having a +.CW .SUFFIXES +dependency line with no sources) and redefine them in the order you +want. (Previously-defined transformation rules will be automatically +redefined as the suffixes they involve are re-entered.) +.LP +Another way to affect the search order is to make the dependency +explicit. In the above example, +.CW a.out +depends on +.CW a.o +and +.CW b.o . +Since a transformation exists from +.CW .o +to +.CW .out , +PMake uses that, as indicated by the +.CW "using existing source a.o" '' `` +message. +.LP +The search for a transformation starts from the suffix of the target +and continues through all the defined transformations, in the order +dictated by the suffix ranking, until an existing file with the same +base (the target name minus the suffix and any leading directories) is +found. At that point, one or more transformation rules will have been +found to change the one existing file into the target. +.LP +For example, ignoring what's in the system makefile for now, say you +have a makefile like this: +.DS +\&.SUFFIXES : .out .o .c .y .l +\&.l.c : + lex $(.IMPSRC) + mv lex.yy.c $(.TARGET) +\&.y.c : + yacc $(.IMPSRC) + mv y.tab.c $(.TARGET) +\&.c.o : + cc -c $(.IMPSRC) +\&.o.out : + cc -o $(.TARGET) $(.IMPSRC) +.DE +and the single file +.CW jive.l . +If you were to type +.CW "pmake -rd ms jive.out" ,'' `` +you would get the following output for +.CW jive.out : +.DS +Suff_FindDeps (jive.out) + trying jive.o...not there + trying jive.c...not there + trying jive.y...not there + trying jive.l...got it + applying .l -> .c to "jive.l" + applying .c -> .o to "jive.c" + applying .o -> .out to "jive.o" +.DE +and this is why: PMake starts with the target +.CW jive.out , +figures out its suffix +.CW .out ) ( +and looks for things it can transform to a +.CW .out +file. In this case, it only finds +.CW .o , +so it looks for the file +.CW jive.o . +It fails to find it, so it looks for transformations into a +.CW .o +file. Again it has only one choice: +.CW .c . +So it looks for +.CW jive.c +and, as you know, fails to find it. At this point it has two choices: +it can create the +.CW .c +file from either a +.CW .y +file or a +.CW .l +file. Since +.CW .y +came first on the +.CW .SUFFIXES +line, it checks for +.CW jive.y +first, but can't find it, so it looks for +.CW jive.l +and, lo and behold, there it is. +At this point, it has defined a transformation path as follows: +.CW .l +\(-> +.CW .c +\(-> +.CW .o +\(-> +.CW .out +and applies the transformation rules accordingly. For completeness, +and to give you a better idea of what PMake actually did with this +three-step transformation, this is what PMake printed for the rest of +the process: +.DS +Suff_FindDeps (jive.o) + using existing source jive.c + applying .c -> .o to "jive.c" +Suff_FindDeps (jive.c) + using existing source jive.l + applying .l -> .c to "jive.l" +Suff_FindDeps (jive.l) +Examining jive.l...modified 17:16:01 Oct 4, 1987...up-to-date +Examining jive.c...non-existent...out-of-date +--- jive.c --- +lex jive.l +\&.\|.\|. meaningless lex output deleted .\|.\|. +mv lex.yy.c jive.c +Examining jive.o...non-existent...out-of-date +--- jive.o --- +cc -c jive.c +Examining jive.out...non-existent...out-of-date +--- jive.out --- +cc -o jive.out jive.o +.DE +.LP +One final question remains: what does PMake do with targets that have +no known suffix? PMake simply pretends it actually has a known suffix +and searches for transformations accordingly. +The suffix it chooses is the source for the +.CW .NULL +.Ix 0 ref .NULL +target mentioned later. In the system makefile, +.CW .out +is chosen as the ``null suffix'' +.Ix 0 def suffix null +.Ix 0 def "null suffix" +because most people use PMake to create programs. You are, however, +free and welcome to change it to a suffix of your own choosing. +The null suffix is ignored, however, when PMake is in compatibility +mode (see chapter 4). +.xH 2 Including Other Makefiles +.Ix 0 def makefile inclusion +.Rd 2 +.LP +Just as for programs, it is often useful to extract certain parts of a +makefile into another file and just include it in other makefiles +somehow. Many compilers allow you say something like +.DS +#include "defs.h" +.DE +to include the contents of +.CW defs.h +in the source file. PMake allows you to do the same thing for +makefiles, with the added ability to use variables in the filenames. +An include directive in a makefile looks either like this: +.DS +#include <file> +.DE +or this +.DS +#include "file" +.DE +The difference between the two is where PMake searches for the file: +the first way, PMake will look for +the file only in the system makefile directory (or directories) +(to find out what that directory is, give PMake the +.B \-h +flag). +.Ix 0 ref flags -h +The system makefile directory search path can be overridden via the +.B \-m +option. +.Ix 0 ref flags -m +For files in double-quotes, the search is more complex: +.RS +.IP 1) +The directory of the makefile that's including the file. +.IP 2) +The current directory (the one in which you invoked PMake). +.IP 3) +The directories given by you using +.B \-I +flags, in the order in which you gave them. +.IP 4) +Directories given by +.CW .PATH +dependency lines (see chapter 4). +.IP 5) +The system makefile directory. +.RE +.LP +in that order. +.LP +You are free to use PMake variables in the filename\*-PMake will +expand them before searching for the file. You must specify the +searching method with either angle brackets or double-quotes +.I outside +of a variable expansion. I.e. the following +.DS +SYSTEM = <command.mk> + +#include $(SYSTEM) +.DE +won't work. +.xH 2 Saving Commands +.LP +.Ix 0 def ... +There may come a time when you will want to save certain commands to +be executed when everything else is done. For instance: you're +making several different libraries at one time and you want to create the +members in parallel. Problem is, +.CW ranlib +is another one of those programs that can't be run more than once in +the same directory at the same time (each one creates a file called +.CW __.SYMDEF +into which it stuffs information for the linker to use. Two of them +running at once will overwrite each other's file and the result will +be garbage for both parties). You might want a way to save the ranlib +commands til the end so they can be run one after the other, thus +keeping them from trashing each other's file. PMake allows you to do +this by inserting an ellipsis (``.\|.\|.'') as a command between +commands to be run at once and those to be run later. +.LP +So for the +.CW ranlib +case above, you might do this: +.Rd 5 +.DS +lib1.a : $(LIB1OBJS) + rm -f $(.TARGET) + ar cr $(.TARGET) $(.ALLSRC) + ... + ranlib $(.TARGET) + +lib2.a : $(LIB2OBJS) + rm -f $(.TARGET) + ar cr $(.TARGET) $(.ALLSRC) + ... + ranlib $(.TARGET) +.DE +.Ix 0 ref variable local .TARGET +.Ix 0 ref variable local .ALLSRC +This would save both +.DS +ranlib $(.TARGET) +.DE +commands until the end, when they would run one after the other +(using the correct value for the +.CW .TARGET +variable, of course). +.LP +Commands saved in this manner are only executed if PMake manages to +re-create everything without an error. +.xH 2 Target Attributes +.LP +PMake allows you to give attributes to targets by means of special +sources. Like everything else PMake uses, these sources begin with a +period and are made up of all upper-case letters. There are various +reasons for using them, and I will try to give examples for most of +them. Others you'll have to find uses for yourself. Think of it as ``an +exercise for the reader.'' By placing one (or more) of these as a source on a +dependency line, you are ``marking the target(s) with that +attribute.'' That's just the way I phrase it, so you know. +.LP +Any attributes given as sources for a transformation rule are applied +to the target of the transformation rule when the rule is applied. +.Ix 0 def attributes +.Ix 0 ref source +.Ix 0 ref target +.nr pw 12 +.IP .DONTCARE \n(pw +.Ix 0 def attributes .DONTCARE +.Ix 0 def .DONTCARE +If a target is marked with this attribute and PMake can't figure out +how to create it, it will ignore this fact and assume the file isn't +really needed or actually exists and PMake just can't find it. This may prove +wrong, but the error will be noted later on, not when PMake tries to create +the target so marked. This attribute also prevents PMake from +attempting to touch the target if it is given the +.B \-t +flag. +.Ix 0 ref flags -t +.IP .EXEC \n(pw +.Ix 0 def attributes .EXEC +.Ix 0 def .EXEC +This attribute causes its shell script to be executed while having no +effect on targets that depend on it. This makes the target into a sort +of subroutine. An example. Say you have some LISP files that need to +be compiled and loaded into a LISP process. To do this, you echo LISP +commands into a file and execute a LISP with this file as its input +when everything's done. Say also that you have to load other files +from another system before you can compile your files and further, +that you don't want to go through the loading and dumping unless one +of +.I your +files has changed. Your makefile might look a little bit +like this (remember, this is an educational example, and don't worry +about the +.CW COMPILE +rule, all will soon become clear, grasshopper): +.DS +system : init a.fasl b.fasl c.fasl + for i in $(.ALLSRC); + do + echo -n '(load "' >> input + echo -n ${i} >> input + echo '")' >> input + done + echo '(dump "$(.TARGET)")' >> input + lisp < input + +a.fasl : a.l init COMPILE +b.fasl : b.l init COMPILE +c.fasl : c.l init COMPILE +COMPILE : .USE + echo '(compile "$(.ALLSRC)")' >> input +init : .EXEC + echo '(load-system)' > input +.DE +.Ix 0 ref .USE +.Ix 0 ref attributes .USE +.Ix 0 ref variable local .ALLSRC +.IP "\&" +.CW .EXEC +sources, don't appear in the local variables of targets that depend on +them (nor are they touched if PMake is given the +.B \-t +flag). +.Ix 0 ref flags -t +Note that all the rules, not just that for +.CW system , +include +.CW init +as a source. This is because none of the other targets can be made +until +.CW init +has been made, thus they depend on it. +.IP .EXPORT \n(pw +.Ix 0 def attributes .EXPORT +.Ix 0 def .EXPORT +This is used to mark those targets whose creation should be sent to +another machine if at all possible. This may be used by some +exportation schemes if the exportation is expensive. You should ask +your system administrator if it is necessary. +.IP .EXPORTSAME \n(pw +.Ix 0 def attributes .EXPORTSAME +.Ix 0 def .EXPORTSAME +Tells the export system that the job should be exported to a machine +of the same architecture as the current one. Certain operations (e.g. +running text through +.CW nroff ) +can be performed the same on any architecture (CPU and +operating system type), while others (e.g. compiling a program with +.CW cc ) +must be performed on a machine with the same architecture. Not all +export systems will support this attribute. +.IP .IGNORE \n(pw +.Ix 0 def attributes .IGNORE +.Ix 0 def .IGNORE attribute +Giving a target the +.CW .IGNORE +attribute causes PMake to ignore errors from any of the target's commands, as +if they all had `\-' before them. +.IP .INVISIBLE \n(pw +.Ix 0 def attributes .INVISIBLE +.Ix 0 def .INVISIBLE +This allows you to specify one target as a source for another without +the one affecting the other's local variables. Useful if, say, you +have a makefile that creates two programs, one of which is used to +create the other, so it must exist before the other is created. You +could say +.DS +prog1 : $(PROG1OBJS) prog2 MAKEINSTALL +prog2 : $(PROG2OBJS) .INVISIBLE MAKEINSTALL +.DE +where +.CW MAKEINSTALL +is some complex .USE rule (see below) that depends on the +.Ix 0 ref .USE +.CW .ALLSRC +variable containing the right things. Without the +.CW .INVISIBLE +attribute for +.CW prog2 , +the +.CW MAKEINSTALL +rule couldn't be applied. This is not as useful as it should be, and +the semantics may change (or the whole thing go away) in the +not-too-distant future. +.IP .JOIN \n(pw +.Ix 0 def attributes .JOIN +.Ix 0 def .JOIN +This is another way to avoid performing some operations in parallel +while permitting everything else to be done so. Specifically it +forces the target's shell script to be executed only if one or more of the +sources was out-of-date. In addition, the target's name, +in both its +.CW .TARGET +variable and all the local variables of any target that depends on it, +is replaced by the value of its +.CW .ALLSRC +variable. +As an example, suppose you have a program that has four libraries that +compile in the same directory along with, and at the same time as, the +program. You again have the problem with +.CW ranlib +that I mentioned earlier, only this time it's more severe: you +can't just put the ranlib off to the end since the program +will need those libraries before it can be re-created. You can do +something like this: +.DS +program : $(OBJS) libraries + cc -o $(.TARGET) $(.ALLSRC) + +libraries : lib1.a lib2.a lib3.a lib4.a .JOIN + ranlib $(.OODATE) +.DE +.Ix 0 ref variable local .TARGET +.Ix 0 ref variable local .ALLSRC +.Ix 0 ref variable local .OODATE +.Ix 0 ref .TARGET +.Ix 0 ref .ALLSRC +.Ix 0 ref .OODATE +In this case, PMake will re-create the +.CW $(OBJS) +as necessary, along with +.CW lib1.a , +.CW lib2.a , +.CW lib3.a +and +.CW lib4.a . +It will then execute +.CW ranlib +on any library that was changed and set +.CW program 's +.CW .ALLSRC +variable to contain what's in +.CW $(OBJS) +followed by +.CW "lib1.a lib2.a lib3.a lib4.a" .'' `` +In case you're wondering, it's called +.CW .JOIN +because it joins together different threads of the ``input graph'' at +the target marked with the attribute. +Another aspect of the .JOIN attribute is it keeps the target from +being created if the +.B \-t +flag was given. +.Ix 0 ref flags -t +.IP .MAKE \n(pw +.Ix 0 def attributes .MAKE +.Ix 0 def .MAKE +The +.CW .MAKE +attribute marks its target as being a recursive invocation of PMake. +This forces PMake to execute the script associated with the target (if +it's out-of-date) even if you gave the +.B \-n +or +.B \-t +flag. By doing this, you can start at the top of a system and type +.DS +pmake -n +.DE +and have it descend the directory tree (if your makefiles are set up +correctly), printing what it would have executed if you hadn't +included the +.B \-n +flag. +.IP .NOEXPORT \n(pw +.Ix 0 def attributes .NOEXPORT +.Ix 0 def .NOEXPORT attribute +If possible, PMake will attempt to export the creation of all targets to +another machine (this depends on how PMake was configured). Sometimes, +the creation is so simple, it is pointless to send it to another +machine. If you give the target the +.CW .NOEXPORT +attribute, it will be run locally, even if you've given PMake the +.B "\-L 0" +flag. +.IP .NOTMAIN \n(pw +.Ix 0 def attributes .NOTMAIN +.Ix 0 def .NOTMAIN +Normally, if you do not specify a target to make in any other way, +PMake will take the first target on the first dependency line of a +makefile as the target to create. That target is known as the ``Main +Target'' and is labeled as such if you print the dependencies out +using the +.B \-p +flag. +.Ix 0 ref flags -p +Giving a target this attribute tells PMake that the target is +definitely +.I not +the Main Target. +This allows you to place targets in an included makefile and +have PMake create something else by default. +.IP .PRECIOUS \n(pw +.Ix 0 def attributes .PRECIOUS +.Ix 0 def .PRECIOUS attribute +When PMake is interrupted (you type control-C at the keyboard), it +will attempt to clean up after itself by removing any half-made +targets. If a target has the +.CW .PRECIOUS +attribute, however, PMake will leave it alone. An additional side +effect of the `::' operator is to mark the targets as +.CW .PRECIOUS . +.Ix 0 ref operator double-colon +.Ix 0 ref :: +.IP .SILENT \n(pw +.Ix 0 def attributes .SILENT +.Ix 0 def .SILENT attribute +Marking a target with this attribute keeps its commands from being +printed when they're executed, just as if they had an `@' in front of them. +.IP .USE \n(pw +.Ix 0 def attributes .USE +.Ix 0 def .USE +By giving a target this attribute, you turn it into PMake's equivalent +of a macro. When the target is used as a source for another target, +the other target acquires the commands, sources and attributes (except +.CW .USE ) +of the source. +If the target already has commands, the +.CW .USE +target's commands are added to the end. If more than one .USE-marked +source is given to a target, the rules are applied sequentially. +.IP "\&" \n(pw +The typical .USE rule (as I call them) will use the sources of the +target to which it is applied (as stored in the +.CW .ALLSRC +variable for the target) as its ``arguments,'' if you will. +For example, you probably noticed that the commands for creating +.CW lib1.a +and +.CW lib2.a +in the example in section 3.3 +.Rm 5 3.3 +were exactly the same. You can use the +.CW .USE +attribute to eliminate the repetition, like so: +.DS +lib1.a : $(LIB1OBJS) MAKELIB +lib2.a : $(LIB2OBJS) MAKELIB + +MAKELIB : .USE + rm -f $(.TARGET) + ar cr $(.TARGET) $(.ALLSRC) + ... + ranlib $(.TARGET) +.DE +.Ix 0 ref variable local .TARGET +.Ix 0 ref variable local .ALLSRC +.IP "\&" \n(pw +Several system makefiles (not to be confused with The System Makefile) +make use of these .USE rules to make your +life easier (they're in the default, system makefile directory...take a look). +Note that the .USE rule source itself +.CW MAKELIB ) ( +does not appear in any of the targets's local variables. +There is no limit to the number of times I could use the +.CW MAKELIB +rule. If there were more libraries, I could continue with +.CW "lib3.a : $(LIB3OBJS) MAKELIB" '' `` +and so on and so forth. +.xH 2 Special Targets +.LP +As there were in Make, so there are certain targets that have special +meaning to PMake. When you use one on a dependency line, it is the +only target that may appear on the left-hand-side of the operator. +.Ix 0 ref target +.Ix 0 ref operator +As for the attributes and variables, all the special targets +begin with a period and consist of upper-case letters only. +I won't describe them all in detail because some of them are rather +complex and I'll describe them in more detail than you'll want in +chapter 4. +The targets are as follows: +.nr pw 10 +.IP .BEGIN \n(pw +.Ix 0 def .BEGIN +Any commands attached to this target are executed before anything else +is done. You can use it for any initialization that needs doing. +.IP .DEFAULT \n(pw +.Ix 0 def .DEFAULT +This is sort of a .USE rule for any target (that was used only as a +source) that PMake can't figure out any other way to create. It's only +``sort of'' a .USE rule because only the shell script attached to the +.CW .DEFAULT +target is used. The +.CW .IMPSRC +variable of a target that inherits +.CW .DEFAULT 's +commands is set to the target's own name. +.Ix 0 ref .IMPSRC +.Ix 0 ref variable local .IMPSRC +.IP .END \n(pw +.Ix 0 def .END +This serves a function similar to +.CW .BEGIN , +in that commands attached to it are executed once everything has been +re-created (so long as no errors occurred). It also serves the extra +function of being a place on which PMake can hang commands you put off +to the end. Thus the script for this target will be executed before +any of the commands you save with the ``.\|.\|.''. +.Ix 0 ref ... +.IP .EXPORT \n(pw +The sources for this target are passed to the exportation system compiled +into PMake. Some systems will use these sources to configure +themselves. You should ask your system administrator about this. +.IP .IGNORE \n(pw +.Ix 0 def .IGNORE target +.Ix 0 ref .IGNORE attribute +.Ix 0 ref attributes .IGNORE +This target marks each of its sources with the +.CW .IGNORE +attribute. If you don't give it any sources, then it is like +giving the +.B \-i +flag when you invoke PMake \*- errors are ignored for all commands. +.Ix 0 ref flags -i +.IP .INCLUDES \n(pw +.Ix 0 def .INCLUDES target +.Ix 0 def variable global .INCLUDES +.Ix 0 def .INCLUDES variable +The sources for this target are taken to be suffixes that indicate a +file that can be included in a program source file. +The suffix must have already been declared with +.CW .SUFFIXES +(see below). +Any suffix so marked will have the directories on its search path +(see +.CW .PATH , +below) placed in the +.CW .INCLUDES +variable, each preceded by a +.B \-I +flag. This variable can then be used as an argument for the compiler +in the normal fashion. The +.CW .h +suffix is already marked in this way in the system makefile. +.Ix 0 ref makefile system +E.g. if you have +.DS +\&.SUFFIXES : .bitmap +\&.PATH.bitmap : /usr/local/X/lib/bitmaps +\&.INCLUDES : .bitmap +.DE +PMake will place +.CW "-I/usr/local/X/lib/bitmaps" '' `` +in the +.CW .INCLUDES +variable and you can then say +.DS +cc $(.INCLUDES) -c xprogram.c +.DE +(Note: the +.CW .INCLUDES +variable is not actually filled in until the entire makefile has been read.) +.IP .INTERRUPT \n(pw +.Ix 0 def .INTERRUPT +When PMake is interrupted, +it will execute the commands in the script for this target, if it +exists. +.IP .LIBS \n(pw +.Ix 0 def .LIBS target +.Ix 0 def .LIBS variable +.Ix 0 def variable global .LIBS +This does for libraries what +.CW .INCLUDES +does for include files, except the flag used is +.B \-L , +as required by those linkers that allow you to tell them where to find +libraries. The variable used is +.CW .LIBS . +Be forewarned that PMake may not have been compiled to do this if the +linker on your system doesn't accept the +.B \-L +flag, though the +.CW .LIBS +variable will always be defined once the makefile has been read. +.IP .MAIN \n(pw +.Ix 0 def .MAIN +If you didn't give a target (or targets) to create when you invoked +PMake, it will take the sources of this target as the targets to +create. +.IP .MAKEFLAGS \n(pw +.Ix 0 def .MAKEFLAGS target +This target provides a way for you to always specify flags for PMake +when the makefile is used. The flags are just as they would be typed +to the shell (except you can't use shell variables unless they're in +the environment), +though the +.B \-f +and +.B \-r +flags have no effect. +.IP .NULL \n(pw +.Ix 0 def .NULL +.Ix 0 ref suffix null +.Ix 0 ref "null suffix" +This allows you to specify what suffix PMake should pretend a file has +if, in fact, it has no known suffix.

PMake defines several +modifiers that may be applied to a variable's value before it is +expanded. You apply a modifier by placing it after the variable name +with a colon between the two, like so: +.DS +${\fIVARIABLE\fP:\fImodifier\fP} +.DE +Each modifier is a single character followed by something specific to +the modifier itself. +You may apply as many modifiers as you want \*- each one is applied to +the result of the previous and is separated from the previous by +another colon. +.LP +There are seven ways to modify a variable's expansion, most of which +come from the C shell variable modification characters: +.RS +.IP "M\fIpattern\fP" +.Ix 0 def :M +.Ix 0 def modifier match +This is used to select only those words (a word is a series of +characters that are neither spaces nor tabs) that match the given +.I pattern . +The pattern is a wildcard pattern like that used by the shell, where +.CW * +means 0 or more characters of any sort; +.CW ? +is any single character; +.CW [abcd] +matches any single character that is either `a', `b', `c' or `d' +(there may be any number of characters between the brackets); +.CW [0-9] +matches any single character that is between `0' and `9' (i.e. any +digit. This form may be freely mixed with the other bracket form), and +`\\' is used to escape any of the characters `*', `?', `[' or `:', +leaving them as regular characters to match themselves in a word. +For example, the system makefile +.CW <makedepend.mk> +uses +.CW "$(CFLAGS:M-[ID]*)" '' `` +to extract all the +.CW \-I +and +.CW \-D +flags that would be passed to the C compiler. This allows it to +properly locate include files and generate the correct dependencies. +.IP "N\fIpattern\fP" +.Ix 0 def :N +.Ix 0 def modifier nomatch +This is identical to +.CW :M +except it substitutes all words that don't match the given pattern. +.IP "S/\fIsearch-string\fP/\fIreplacement-string\fP/[g]" +.Ix 0 def :S +.Ix 0 def modifier substitute +Causes the first occurrence of +.I search-string +in the variable to be replaced by +.I replacement-string , +unless the +.CW g +flag is given at the end, in which case all occurrences of the string +are replaced. The substitution is performed on each word in the +variable in turn. If +.I search-string +begins with a +.CW ^ , +the string must match starting at the beginning of the word. If +.I search-string +ends with a +.CW $ , +the string must match to the end of the word (these two may be +combined to force an exact match). If a backslash precedes these two +characters, however, they lose their special meaning. Variable +expansion also occurs in the normal fashion inside both the +.I search-string +and the +.I replacement-string , +.B except +that a backslash is used to prevent the expansion of a +.CW $ , +not another dollar sign, as is usual. +Note that +.I search-string +is just a string, not a pattern, so none of the usual +regular-expression/wildcard characters have any special meaning save +.CW ^ +and +.CW $ . +In the replacement string, +the +.CW & +character is replaced by the +.I search-string +unless it is preceded by a backslash. +You are allowed to use any character except +colon or exclamation point to separate the two strings. This so-called +delimiter character may be placed in either string by preceding it +with a backslash. +.IP T +.Ix 0 def :T +.Ix 0 def modifier tail +Replaces each word in the variable expansion by its last +component (its ``tail''). For example, given +.DS +OBJS = ../lib/a.o b /usr/lib/libm.a +TAILS = $(OBJS:T) +.DE +the variable +.CW TAILS +would expand to +.CW "a.o b libm.a" .'' `` +.IP H +.Ix 0 def :H +.Ix 0 def modifier head +This is similar to +.CW :T , +except that every word is replaced by everything but the tail (the +``head''). Using the same definition of +.CW OBJS , +the string +.CW "$(OBJS:H)" '' `` +would expand to +.CW "../lib /usr/lib" .'' `` +Note that the final slash on the heads is removed and +anything without a head is replaced by the empty string. +.IP E +.Ix 0 def :E +.Ix 0 def modifier extension +.Ix 0 def modifier suffix +.Ix 0 ref suffix "variable modifier" +.CW :E +replaces each word by its suffix (``extension'').

The search is anchored at +the end of each word, so only suffixes or whole words may be replaced. +.xH 2 More on Debugging +.xH 2 More Exercises +.IP (3.1) +You've got a set programs, each of which is created from its own +assembly-language source file (suffix +.CW .asm ). +Each program can be assembled into two versions, one with error-checking +code assembled in and one without. You could assemble them into files +with different suffixes +.CW .eobj \& ( +and +.CW .obj , +for instance), but your linker only understands files that end in +.CW .obj . +To top it all off, the final executables +.I must +have the suffix +.CW .exe . +How can you still use transformation rules to make your life easier +(Hint: assume the error-checking versions have +.CW ec +tacked onto their prefix)? +.IP (3.2) +Assume, for a moment or two, you want to perform a sort of +``indirection'' by placing the name of a variable into another one, +then you want to get the value of the first by expanding the second +somehow. Unfortunately, PMake doesn't allow constructs like +.DS I +$($(FOO)) +.DE +What do you do? Hint: no further variable expansion is performed after +modifiers are applied, thus if you cause a $ to occur in the +expansion, that's what will be in the result. +.xH 1 PMake for Gods +.LP +This chapter is devoted to those facilities in PMake that allow you to +do a great deal in a makefile with very little work, as well as do +some things you couldn't do in Make without a great deal of work (and +perhaps the use of other programs). The problem with these features, +is they must be handled with care, or you will end up with a mess. +.LP +Once more, I assume a greater familiarity with +.UX +or Sprite than I did in the previous two chapters. +.xH 2 Search Paths +.Rd 6 +.LP +PMake supports the dispersal of files into multiple directories by +allowing you to specify places to look for sources with +.CW .PATH +targets in the makefile. The directories you give as sources for these +targets make up a ``search path.'' Only those files used exclusively +as sources are actually sought on a search path, the assumption being +that anything listed as a target in the makefile can be created by the +makefile and thus should be in the current directory. +.LP +There are two types of search paths +in PMake: one is used for all types of files (including included +makefiles) and is specified with a plain +.CW .PATH +target (e.g. +.CW ".PATH : RCS" ''), `` +while the other is specific to a certain type of file, as indicated by +the file's suffix. A specific search path is indicated by immediately following +the +.CW .PATH +with the suffix of the file. For instance +.DS +\&.PATH.h : /sprite/lib/include /sprite/att/lib/include +.DE +would tell PMake to look in the directories +.CW /sprite/lib/include +and +.CW /sprite/att/lib/include +for any files whose suffix is +.CW .h . +.LP +The current directory is always consulted first to see if a file +exists. Only if it cannot be found there are the directories in the +specific search path, followed by those in the general search path, +consulted. +.LP +A search path is also used when expanding wildcard characters. If the +pattern has a recognizable suffix on it, the path for that suffix will +be used for the expansion. Otherwise the default search path is employed. +.LP +When a file is found in some directory other than the current one, all +local variables that would have contained the target's name +.CW .ALLSRC , ( +and +.CW .IMPSRC ) +will instead contain the path to the file, as found by PMake. +Thus if you have a file +.CW ../lib/mumble.c +and a makefile +.DS +\&.PATH.c : ../lib +mumble : mumble.c + $(CC) -o $(.TARGET) $(.ALLSRC) +.DE +the command executed to create +.CW mumble +would be +.CW "cc -o mumble ../lib/mumble.c" .'' `` +(As an aside, the command in this case isn't strictly necessary, since +it will be found using transformation rules if it isn't given. This is because +.CW .out +is the null suffix by default and a transformation exists from +.CW .c +to +.CW .out . +Just thought I'd throw that in.) +.LP +If a file exists in two directories on the same search path, the file +in the first directory on the path will be the one PMake uses. So if +you have a large system spread over many directories, it would behoove +you to follow a naming convention that avoids such conflicts. +.LP +Something you should know about the way search paths are implemented +is that each directory is read, and its contents cached, exactly once +\&\*- when it is first encountered \*- so any changes to the +directories while PMake is running will not be noted when searching +for implicit sources, nor will they be found when PMake attempts to +discover when the file was last modified, unless the file was created in the +current directory. While people have suggested that PMake should read +the directories each time, my experience suggests that the caching seldom +causes problems. In addition, not caching the directories slows things +down enormously because of PMake's attempts to apply transformation +rules through non-existent files \*- the number of extra file-system +searches is truly staggering, especially if many files without +suffixes are used and the null suffix isn't changed from +.CW .out . +.xH 2 Archives and Libraries +.LP +.UX +and Sprite allow you to merge files into an archive using the +.CW ar +command. Further, if the files are relocatable object files, you can +run +.CW ranlib +on the archive and get yourself a library that you can link into any +program you want. The main problem with archives is they double the +space you need to store the archived files, since there's one copy in +the archive and one copy out by itself. The problem with libraries is +you usually think of them as +.CW -lm +rather than +.CW /usr/lib/libm.a +and the linker thinks they're out-of-date if you so much as look at +them. +.LP +PMake solves the problem with archives by allowing you to tell it to +examine the files in the archives (so you can remove the individual +files without having to regenerate them later). To handle the problem +with libraries, PMake adds an additional way of deciding if a library +is out-of-date: +.IP \(bu 2 +If the table of contents is older than the library, or is missing, the +library is out-of-date. +.LP +A library is any target that looks like +.CW \-l name'' `` +or that ends in a suffix that was marked as a library using the +.CW .LIBS +target. +.CW .a +is so marked in the system makefile. +.LP +Members of an archive are specified as +``\fIarchive\fP(\fImember\fP[ \fImember\fP...])''. +Thus +.CW libdix.a(window.o) '' ``' +specifies the file +.CW window.o +in the archive +.CW libdix.a . +You may also use wildcards to specify the members of the archive. Just +remember that most the wildcard characters will only find +.I existing +files. +.LP +A file that is a member of an archive is treated specially. If the +file doesn't exist, but it is in the archive, the modification time +recorded in the archive is used for the file when determining if the +file is out-of-date. When figuring out how to make an archived member target +(not the file itself, but the file in the archive \*- the +\fIarchive\fP(\fImember\fP) target), special care is +taken with the transformation rules, as follows: +.IP \(bu 2 +\&\fIarchive\fP(\fImember\fP) is made to depend on \fImember\fP. +.IP \(bu 2 +The transformation from the \fImember\fP's suffix to the +\fIarchive\fP's suffix is applied to the \fIarchive\fP(\fImember\fP) target. +.IP \(bu 2 +The \fIarchive\fP(\fImember\fP)'s +.CW .TARGET +variable is set to the name of the \fImember\fP if \fImember\fP is +actually a target, or the path to the member file if \fImember\fP is +only a source. +.IP \(bu 2 +The +.CW .ARCHIVE +variable for the \fIarchive\fP(\fImember\fP) target is set to the name +of the \fIarchive\fP. +.Ix 0 def variable local .ARCHIVE +.Ix 0 def .ARCHIVE +.IP \(bu 2 +The +.CW .MEMBER +variable is set to the actual string inside the parentheses. In most +cases, this will be the same as the +.CW .TARGET +variable. +.Ix 0 def variable local .MEMBER +.Ix 0 def .MEMBER +.IP \(bu 2 +The \fIarchive\fP(\fImember\fP)'s place in the local variables of the +targets that depend on it is taken by the value of its +.CW .TARGET +variable. +.LP +Thus, a program library could be created with the following makefile: +.DS +\&.o.a : + ... + rm -f $(.TARGET:T) +OBJS = obj1.o obj2.o obj3.o +libprog.a : libprog.a($(OBJS)) + ar cru $(.TARGET) $(.OODATE) + ranlib $(.TARGET) +.DE +This will cause the three object files to be compiled (if the +corresponding source files were modified after the object file or, if +that doesn't exist, the archived object file), the out-of-date ones +archived in +.CW libprog.a , +a table of contents placed in the archive and the newly-archived +object files to be removed. +.LP +All this is used in the +.CW makelib.mk +system makefile to create a single library with ease. This makefile +looks like this: +.DS +.SM +# +# Rules for making libraries. The object files that make up the library +# are removed once they are archived. +# +# To make several libraries in parallel, you should define the variable +# "many_libraries".

A +conditional looks like this: +.DS +#if \fIboolean expression\fP +\fIlines\fP +#elif \fIanother boolean expression\fP +\fImore lines\fP +#else +\fIstill more lines\fP +#endif +.DE +They may be nested to a maximum depth of 30 and may occur anywhere +(except in a comment, of course). The +.CW # '' `` +must the very first character on the line. +.LP +Each +.I "boolean expression" +is made up of terms that look like function calls, the standard C +boolean operators +.CW && , +.CW || , +and +.CW ! , +and the standard relational operators +.CW == , +.CW != , +.CW > , +.CW >= , +.CW < , +and +.CW <= , +with +.CW == +and +.CW != +being overloaded to allow string comparisons as well. +.CW && +represents logical AND; +.CW || +is logical OR and +.CW ! +is logical NOT. The arithmetic and string operators take precedence +over all three of these operators, while NOT takes precedence over +AND, which takes precedence over OR. This precedence may be +overridden with parentheses, and an expression may be parenthesized to +your heart's content. Each term looks like a call on one of four +functions: +.nr pw 9 +.Ix 0 def make +.Ix 0 def conditional make +.Ix 0 def if make +.IP make \n(pw +The syntax is +.CW make( \fItarget\fP\c +.CW ) +where +.I target +is a target in the makefile.

The +function returns true if the resulting string is empty (NOTE: an undefined +variable in this context will cause at the very least a warning +message about a malformed conditional, and at the worst will cause the +process to stop once it has read the makefile. If you want to check +for a variable being defined or empty, use the expression +.CW !defined( \fIvar\fP\c `` +.CW ") || empty(" \fIvar\fP\c +.CW ) '' +as the definition of +.CW || +will prevent the +.CW empty() +from being evaluated and causing an error, if the variable is +undefined). This can be used to see if a variable contains a given +word, for example: +.DS +#if !empty(\fIvar\fP:M\fIword\fP) +.DE +.LP +The arithmetic and string operators may only be used to test the value +of a variable. The lefthand side must contain the variable expansion, +while the righthand side contains either a string, enclosed in +double-quotes, or a number. The standard C numeric conventions (except +for specifying an octal number) apply to both sides. E.g. +.DS +#if $(OS) == 4.3 + +#if $(MACHINE) == "sun3" + +#if $(LOAD_ADDR) < 0xc000 +.DE +are all valid conditionals. In addition, the numeric value of a +variable can be tested as a boolean as follows: +.DS +#if $(LOAD) +.DE +would see if +.CW LOAD +contains a non-zero value and +.DS +#if !$(LOAD) +.DE +would test if +.CW LOAD +contains a zero value. +.LP +In addition to the bare +.CW #if ,'' `` +there are other forms that apply one of the first two functions to each +term. They are as follows: +.DS + ifdef \fRdefined\fP + ifndef \fR!defined\fP + ifmake \fRmake\fP + ifnmake \fR!make\fP +.DE +There are also the ``else if'' forms: +.CW elif , +.CW elifdef , +.CW elifndef , +.CW elifmake , +and +.CW elifnmake . +.LP +For instance, if you wish to create two versions of a program, one of which +is optimized (the production version) and the other of which is for debugging +(has symbols for dbx), you have two choices: you can create two +makefiles, one of which uses the +.CW \-g +flag for the compilation, while the other uses the +.CW \-O +flag, or you can use another target (call it +.CW debug ) +to create the debug version. The construct below will take care of +this for you. I have also made it so defining the variable +.CW DEBUG +(say with +.CW "pmake -D DEBUG" ) +will also cause the debug version to be made. +.DS +#if defined(DEBUG) || make(debug) +CFLAGS += -g +#else +CFLAGS += -O +#endif +.DE +There are, of course, problems with this approach. The most glaring +annoyance is that if you want to go from making a debug version to +making a production version, you have to remove all the object files, +or you will get some optimized and some debug versions in the same +program. Another annoyance is you have to be careful not to make two +targets that ``conflict'' because of some conditionals in the +makefile. For instance +.DS +#if make(print) +FORMATTER = ditroff -Plaser_printer +#endif +#if make(draft) +FORMATTER = nroff -Pdot_matrix_printer +#endif +.DE +would wreak havoc if you tried +.CW "pmake draft print" '' `` +since you would use the same formatter for each target. As I said, +this all gets somewhat complicated. +.xH 2 A Shell is a Shell is a Shell +.Rd 7 +.LP +In normal operation, the Bourne Shell (better known as +.CW sh '') `` +is used to execute the commands to re-create targets. PMake also allows you +to specify a different shell for it to use when executing these +commands. There are several things PMake must know about the shell you +wish to use. These things are specified as the sources for the +.CW .SHELL +.Ix 0 ref .SHELL +.Ix 0 ref target .SHELL +target by keyword, as follows: +.IP "\fBpath=\fP\fIpath\fP" +PMake needs to know where the shell actually resides, so it can +execute it. If you specify this and nothing else, PMake will use the +last component of the path and look in its table of the shells it +knows and use the specification it finds, if any. Use this if you just +want to use a different version of the Bourne or C Shell (yes, PMake knows +how to use the C Shell too). +.IP "\fBname=\fP\fIname\fP" +This is the name by which the shell is to be known. It is a single +word and, if no other keywords are specified (other than +.B path ), +it is the name by which PMake attempts to find a specification for +it (as mentioned above). You can use this if you would just rather use +the C Shell than the Bourne Shell +.CW ".SHELL: name=csh" '' (`` +will do it). +.IP "\fBquiet=\fP\fIecho-off command\fP" +As mentioned before, PMake actually controls whether commands are +printed by introducing commands into the shell's input stream. This +keyword, and the next two, control what those commands are. The +.B quiet +keyword is the command used to turn echoing off. Once it is turned +off, echoing is expected to remain off until the echo-on command is given. +.IP "\fBecho=\fP\fIecho-on command\fP" +The command PMake should give to turn echoing back on again. +.IP "\fBfilter=\fP\fIprinted echo-off command\fP" +Many shells will echo the echo-off command when it is given. This +keyword tells PMake in what format the shell actually prints the +echo-off command. Wherever PMake sees this string in the shell's +output, it will delete it and any following whitespace, up to and +including the next newline. See the example at the end of this section +for more details. +.IP "\fBechoFlag=\fP\fIflag to turn echoing on\fP" +Unless a target has been marked +.CW .SILENT , +PMake wants to start the shell running with echoing on. To do this, it +passes this flag to the shell as one of its arguments. If either this +or the next flag begins with a `\-', the flags will be passed to the +shell as separate arguments. Otherwise, the two will be concatenated +(if they are used at the same time, of course). +.IP "\fBerrFlag=\fP\fIflag to turn error checking on\fP" +Likewise, unless a target is marked +.CW .IGNORE , +PMake wishes error-checking to be on from the very start. To this end, +it will pass this flag to the shell as an argument. The same rules for +an initial `\-' apply as for the +.B echoFlag . +.IP "\fBcheck=\fP\fIcommand to turn error checking on\fP" +Just as for echo-control, error-control is achieved by inserting +commands into the shell's input stream. This is the command to make +the shell check for errors. It also serves another purpose if the +shell doesn't have error-control as commands, but I'll get into that +in a minute. Again, once error checking has been turned on, it is +expected to remain on until it is turned off again. +.IP "\fBignore=\fP\fIcommand to turn error checking off\fP" +This is the command PMake uses to turn error checking off. It has +another use if the shell doesn't do error-control, but I'll tell you +about that.\|.\|.\|now. +.IP "\fBhasErrCtl=\fP\fIyes or no\fP" +This takes a value that is either +.B yes +or +.B no . +Now you might think that the existence of the +.B check +and +.B ignore +keywords would be enough to tell PMake if the shell can do +error-control, but you'd be wrong. If +.B hasErrCtl +is +.B yes , +PMake uses the check and ignore commands in a straight-forward manner. +If this is +.B no , +however, their use is rather different. In this case, the check +command is used as a template, in which the string +.B %s +is replaced by the command that's about to be executed, to produce a +command for the shell that will echo the command to be executed. The +ignore command is also used as a template, again with +.B %s +replaced by the command to be executed, to produce a command that will +execute the command to be executed and ignore any error it returns. +When these strings are used as templates, you must provide newline(s) +.CW \en '') (`` +in the appropriate place(s). +.LP +The strings that follow these keywords may be enclosed in single or +double quotes (the quotes will be stripped off) and may contain the +usual C backslash-characters (\en is newline, \er is return, \eb is +backspace, \e' escapes a single-quote inside single-quotes, \e" +escapes a double-quote inside double-quotes). Now for an example. +.LP +This is actually the contents of the +.CW <shx.mk> +system makefile, and causes PMake to use the Bourne Shell in such a +way that each command is printed as it is executed. That is, if more +than one command is given on a line, each will be printed separately. +Similarly, each time the body of a loop is executed, the commands +within that loop will be printed, etc. The specification runs like +this: +.DS +# +# This is a shell specification to have the Bourne shell echo +# the commands just before executing them, rather than when it reads +# them. Useful if you want to see how variables are being expanded, etc. +# +\&.SHELL : path=/bin/sh \e + quiet="set -" \e + echo="set -x" \e + filter="+ set - " \e + echoFlag=x \e + errFlag=e \e + hasErrCtl=yes \e + check="set -e" \e + ignore="set +e" +.DE +.LP +It tells PMake the following: +.Bp +The shell is located in the file +.CW /bin/sh . +It need not tell PMake that the name of the shell is +.CW sh +as PMake can figure that out for itself (it's the last component of +the path). +.Bp +The command to stop echoing is +.CW "set -" . +.Bp +The command to start echoing is +.CW "set -x" . +.Bp +When the echo off command is executed, the shell will print +.CW "+ set - " +(The `+' comes from using the +.CW \-x +flag (rather than the +.CW \-v +flag PMake usually uses)). PMake will remove all occurrences of this +string from the output, so you don't notice extra commands you didn't +put there. +.Bp +The flag the Bourne Shell will take to start echoing in this way is +the +.CW \-x +flag. The Bourne Shell will only take its flag arguments concatenated +as its first argument, so neither this nor the +.B errFlag +specification begins with a \-. +.Bp +The flag to use to turn error-checking on from the start is +.CW \-e . +.Bp +The shell can turn error-checking on and off, and the commands to do +so are +.CW "set +e" +and +.CW "set -e" , +respectively. +.LP +I should note that this specification is for Bourne Shells that are +not part of Berkeley +.UX , +as shells from Berkeley don't do error control. You can get a similar +effect, however, by changing the last three lines to be: +.DS + hasErrCtl=no \e + check="echo \e"+ %s\e"\en" \e + ignore="sh -c '%s || exit 0\en" +.DE +.LP +This will cause PMake to execute the two commands +.DS +echo "+ \fIcmd\fP" +sh -c '\fIcmd\fP || true' +.DE +for each command for which errors are to be ignored. (In case you are +wondering, the thing for +.CW ignore +tells the shell to execute another shell without error checking on and +always exit 0, since the +.B || +causes the +.CW "exit 0" +to be executed only if the first command exited non-zero, and if the +first command exited zero, the shell will also exit zero, since that's +the last command it executed). +.xH 2 Compatibility +.Ix 0 ref compatibility +.LP +There are three (well, 3 \(12) levels of backwards-compatibility built +into PMake. Most makefiles will need none at all. Some may need a +little bit of work to operate correctly when run in parallel. Each +level encompasses the previous levels (e.g. +.B \-B +(one shell per command) implies +.B \-V ) +The three levels are described in the following three sections. +.xH 3 DEFCON 3 \*- Variable Expansion +.Ix 0 ref compatibility +.LP +As noted before, PMake will not expand a variable unless it knows of a +value for it. This can cause problems for makefiles that expect to +leave variables undefined except in special circumstances (e.g. if +more flags need to be passed to the C compiler or the output from a +text processor should be sent to a different printer). If the +variables are enclosed in curly braces +.CW ${PRINTER} ''), (`` +the shell will let them pass. If they are enclosed in parentheses, +however, the shell will declare a syntax error and the make will come +to a grinding halt. +.LP +You have two choices: change the makefile to define the variables +(their values can be overridden on the command line, since that's +where they would have been set if you used Make, anyway) or always give the +.B \-V +flag (this can be done with the +.CW .MAKEFLAGS +target, if you want). +.xH 3 DEFCON 2 \*- The Number of the Beast +.Ix 0 ref compatibility +.LP +Then there are the makefiles that expect certain commands, such as +changing to a different directory, to not affect other commands in a +target's creation script. You can solve this is either by going +back to executing one shell per command (which is what the +.B \-B +flag forces PMake to do), which slows the process down a good bit and +requires you to use semicolons and escaped newlines for shell constructs, or +by changing the makefile to execute the offending command(s) in a subshell +(by placing the line inside parentheses), like so: +.DS +install :: .MAKE + (cd src; $(.PMAKE) install) + (cd lib; $(.PMAKE) install) + (cd man; $(.PMAKE) install) +.DE +.Ix 0 ref operator double-colon +.Ix 0 ref variable global .PMAKE +.Ix 0 ref .PMAKE +.Ix 0 ref .MAKE +.Ix 0 ref attribute .MAKE +This will always execute the three makes (even if the +.B \-n +flag was given) because of the combination of the ``::'' operator and +the +.CW .MAKE +attribute. Each command will change to the proper directory to perform +the install, leaving the main shell in the directory in which it started. +.xH 3 "DEFCON 1 \*- Imitation is the Not the Highest Form of Flattery" +.Ix 0 ref compatibility +.LP +The final category of makefile is the one where every command requires +input, the dependencies are incompletely specified, or you simply +cannot create more than one target at a time, as mentioned earlier. In +addition, you may not have the time or desire to upgrade the makefile +to run smoothly with PMake. If you are the conservative sort, this is +the compatibility mode for you. It is entered either by giving PMake +the +.B \-M +flag (for Make), or by executing PMake as +.CW make .'' `` +In either case, PMake performs things exactly like Make (while still +supporting most of the nice new features PMake provides). This +includes: +.IP \(bu 2 +No parallel execution. +.IP \(bu 2 +Targets are made in the exact order specified by the makefile. The +sources for each target are made in strict left-to-right order, etc. +.IP \(bu 2 +A single Bourne shell is used to execute each command, thus the +shell's +.CW $$ +variable is useless, changing directories doesn't work across command +lines, etc. +.IP \(bu 2 +If no special characters exist in a command line, PMake will break the +command into words itself and execute the command directly, without +executing a shell first. The characters that cause PMake to execute a +shell are: +.CW # , +.CW = , +.CW | , +.CW ^ , +.CW ( , +.CW ) , +.CW { , +.CW } , +.CW ; , +.CW & , +.CW < , +.CW > , +.CW * , +.CW ? , +.CW [ , +.CW ] , +.CW : , +.CW $ , +.CW ` , +and +.CW \e . +You should notice that these are all the characters that are given +special meaning by the shell (except +.CW ' +and +.CW " , +which PMake deals with all by its lonesome). +.IP \(bu 2 +The use of the null suffix is turned off. +.Ix 0 ref "null suffix" +.Ix 0 ref suffix null +.xH 2 The Way Things Work +.LP +When PMake reads the makefile, it parses sources and targets into +nodes in a graph. The graph is directed only in the sense that PMake +knows which way is up. Each node contains not only links to all its +parents and children (the nodes that depend on it and those on which +it depends, respectively), but also a count of the number of its +children that have already been processed. +.LP +The most important thing to know about how PMake uses this graph is +that the traversal is breadth-first and occurs in two passes. +.LP +After PMake has parsed the makefile, it begins with the nodes the user +has told it to make (either on the command line, or via a +.CW .MAIN +target, or by the target being the first in the file not labeled with +the +.CW .NOTMAIN +attribute) placed in a queue. It continues to take the node off the +front of the queue, mark it as something that needs to be made, pass +the node to +.CW Suff_FindDeps +(mentioned earlier) to find any implicit sources for the node, and +place all the node's children that have yet to be marked at the end of +the queue. If any of the children is a +.CW .USE +rule, its attributes are applied to the parent, then its commands are +appended to the parent's list of commands and its children are linked +to its parent. The parent's unmade children counter is then decremented +(since the +.CW .USE +node has been processed). You will note that this allows a +.CW .USE +node to have children that are +.CW .USE +nodes and the rules will be applied in sequence. +If the node has no children, it is placed at the end of +another queue to be examined in the second pass. This process +continues until the first queue is empty. +.LP +At this point, all the leaves of the graph are in the examination +queue. PMake removes the node at the head of the queue and sees if it +is out-of-date. If it is, it is passed to a function that will execute +the commands for the node asynchronously. When the commands have +completed, all the node's parents have their unmade children counter +decremented and, if the counter is then 0, they are placed on the +examination queue. Likewise, if the node is up-to-date. Only those +parents that were marked on the downward pass are processed in this +way. Thus PMake traverses the graph back up to the nodes the user +instructed it to create. When the examination queue is empty and no +shells are running to create a target, PMake is finished. +.LP +Once all targets have been processed, PMake executes the commands +attached to the +.CW .END +target, either explicitly or through the use of an ellipsis in a shell +script. If there were no errors during the entire process but there +are still some targets unmade (PMake keeps a running count of how many +targets are left to be made), there is a cycle in the graph. PMake does +a depth-first traversal of the graph to find all the targets that +weren't made and prints them out one by one. +.xH 1 Answers to Exercises +.IP (3.1) +This is something of a trick question, for which I apologize. The +trick comes from the UNIX definition of a suffix, which PMake doesn't +necessarily share. You will have noticed that all the suffixes used in +this tutorial (and in UNIX in general) begin with a period +.CW .ms , ( +.CW .c , +etc.). Now, PMake's idea of a suffix is more like English's: it's the +characters at the end of a word. With this in mind, one possible +.Ix 0 def suffix +solution to this problem goes as follows: +.DS I +\&.SUFFIXES : ec.exe .exe ec.obj .obj .asm +ec.objec.exe .obj.exe : + link -o $(.TARGET) $(.IMPSRC) +\&.asmec.obj : + asm -o $(.TARGET) -DDO_ERROR_CHECKING $(.IMPSRC) +\&.asm.obj : + asm -o $(.TARGET) $(.IMPSRC) +.DE +.IP (3.2) +The trick to this one lies in the ``:='' variable-assignment operator +and the ``:S'' variable-expansion modifier. +.Ix 0 ref variable assignment expanded +.Ix 0 ref variable expansion modified +.Ix 0 ref modifier substitute +.Ix 0 ref :S +.Ix 0 ref := +Basically what you want is to take the pointer variable, so to speak, +and transform it into an invocation of the variable at which it +points. You might try something like +.DS I +$(PTR:S/^/\e$(/:S/$/)) +.DE +which places +.CW $( '' `` +at the front of the variable name and +.CW ) '' `` +at the end, thus transforming +.CW VAR ,'' `` +for example, into +.CW $(VAR) ,'' `` +which is just what we want. Unfortunately (as you know if you've tried +it), since, as it says in the hint, PMake does no further substitution +on the result of a modified expansion, that's \fIall\fP you get. The +solution is to make use of ``:='' to place that string into yet +another variable, then invoke the other variable directly: +.DS I +*PTR := $(PTR:S/^/\e$(/:S/$/)/) +.DE +You can then use +.CW $(*PTR) '' `` +to your heart's content. +.de Gp +.XP +\&\fB\\$1:\fP +.. +.xH 1 Glossary of Jargon +.Gp "attribute" +A property given to a target that causes PMake to treat it differently. +.Gp "command script" +The lines immediately following a dependency line that specify +commands to execute to create each of the targets on the dependency +line. Each line in the command script must begin with a tab. +.Gp "command-line variable" +A variable defined in an argument when PMake is first executed. +Overrides all assignments to the same variable name in the makefile. +.Gp "conditional" +A construct much like that used in C that allows a makefile to be +configured on the fly based on the local environment, or on what is being +made by that invocation of PMake. +.Gp "creation script" +Commands used to create a target. See ``command script.'' +.Gp "dependency" +The relationship between a source and a target. This comes in three +flavors, as indicated by the operator between the target and the +source. `:' gives a straight time-wise dependency (if the target is +older than the source, the target is out-of-date), while `!' provides +simply an ordering and always considers the target out-of-date. `::' +is much like `:', save it creates multiple instances of a target each +of which depends on its own list of sources. +.Gp "dynamic source" +This refers to a source that has a local variable invocation in it. It +allows a single dependency line to specify a different source for each +target on the line. +.Gp "global variable" +Any variable defined in a makefile. Takes precedence over variables +defined in the environment, but not over command-line or local variables. +.Gp "input graph" +What PMake constructs from a makefile. Consists of nodes made of the +targets in the makefile, and the links between them (the +dependencies). The links are directed (from source to target) and +there may not be any cycles (loops) in the graph. +.Gp "local variable" +A variable defined by PMake visible only in a target's shell script. +There are seven local variables, not all of which are defined for +every target: +.CW .TARGET , +.CW .ALLSRC , +.CW .OODATE , +.CW .PREFIX , +.CW .IMPSRC , +.CW .ARCHIVE , +and +.CW .MEMBER . +.CW .TARGET , +.CW .PREFIX , +.CW .ARCHIVE , +and +.CW .MEMBER +may be used on dependency lines to create ``dynamic sources.'' +.Gp "makefile" +A file that describes how a system is built. If you don't know what it +is after reading this tutorial.\|.\|.\|. +.Gp "modifier" +A letter, following a colon, used to alter how a variable is expanded. +It has no effect on the variable itself. +.Gp "operator" +What separates a source from a target (on a dependency line) and specifies +the relationship between the two. There are three: +.CW : ', ` +.CW :: ', ` +and +.CW ! '. ` +.Gp "search path" +A list of directories in which a file should be sought. PMake's view +of the contents of directories in a search path does not change once +the makefile has been read. A file is sought on a search path only if +it is exclusively a source. +.Gp "shell" +A program to which commands are passed in order to create targets. +.Gp "source" +Anything to the right of an operator on a dependency line. Targets on +the dependency line are usually created from the sources. +.Gp "special target" +A target that causes PMake to do special things when it's encountered. +.Gp "suffix" +The tail end of a file name. Usually begins with a period, +.CW .c +or +.CW .ms , +e.g. +.Gp "target" +A word to the left of the operator on a dependency line. More +generally, any file that PMake might create. A file may be (and often +is) both a target and a source (what it is depends on how PMake is +looking at it at the time \*- sort of like the wave/particle duality +of light, you know). +.Gp "transformation rule" +A special construct in a makefile that specifies how to create a file +of one type from a file of another, as indicated by their suffixes. +.Gp "variable expansion" +The process of substituting the value of a variable for a reference to +it. Expansion may be altered by means of modifiers. +.Gp "variable" +A place in which to store text that may be retrieved later. Also used +to define the local environment. Conditionals exist that test whether +a variable is defined or not. +.bp +.\" Output table of contents last, with an entry for the index, making +.\" sure to save and restore the last real page number for the index... +.nr @n \n(PN+1 +.\" We are not generating an index +.\" .XS \n(@n +.\" Index +.\" .XE +.nr %% \n% +.PX +.nr % \n(%% diff --git a/20130123/README b/20130123/README new file mode 100644 index 0000000..fb688a3 --- /dev/null +++ b/20130123/README @@ -0,0 +1,47 @@ + bmake + +This directory contains a port of the BSD make tool (from NetBSD) +I have run it on SunOS,Solaris,HP-UX,AIX,IRIX,FreeBSD and Linux. + +Version 3 was re-worked from scratch to better facilitate +importing newer make(1) versions from NetBSD.

instead of the default +.Ql Pa makefile . +If +.Ar makefile +is +.Ql Fl , +standard input is read. +Multiple makefiles may be specified, and are read in the order specified. +.It Fl I Ar directory +Specify a directory in which to search for makefiles and included makefiles. +The system makefile directory (or directories, see the +.Fl m +option) is automatically included as part of this list. +.It Fl i +Ignore non-zero exit of shell commands in the makefile. +Equivalent to specifying +.Ql Fl +before each command line in the makefile. +.It Fl J Ar private +This option should +.Em not +be specified by the user. +.Pp +When the +.Ar j +option is in use in a recursive build, this option is passed by a make +to child makes to allow all the make processes in the build to +cooperate to avoid overloading the system. +.It Fl j Ar max_jobs +Specify the maximum number of jobs that +.Nm +may have running at any one time. +The value is saved in +.Va .MAKE.JOBS . +Turns compatibility mode off, unless the +.Ar B +flag is also specified. +When compatibility mode is off, all commands associated with a +target are executed in a single shell invocation as opposed to the +traditional one shell invocation per line. +This can break traditional scripts which change directories on each +command invocation and then expect to start with a fresh environment +on the next line. +It is more efficient to correct the scripts rather than turn backwards +compatibility on. +.It Fl k +Continue processing after errors are encountered, but only on those targets +that do not depend on the target whose creation caused the error. +.It Fl m Ar directory +Specify a directory in which to search for sys.mk and makefiles included +via the +.Ao Ar file Ac Ns -style +include statement. +The +.Fl m +option can be used multiple times to form a search path. +This path will override the default system include path: /usr/share/mk. +Furthermore the system include path will be appended to the search path used +for +.Qo Ar file Qc Ns -style +include statements (see the +.Fl I +option). +.Pp +If a file or directory name in the +.Fl m +argument (or the +.Ev MAKESYSPATH +environment variable) starts with the string +.Qq \&.../ +then +.Nm +will search for the specified file or directory named in the remaining part +of the argument string. +The search starts with the current directory of +the Makefile and then works upward towards the root of the filesystem. +If the search is successful, then the resulting directory replaces the +.Qq \&.../ +specification in the +.Fl m +argument. +If used, this feature allows +.Nm +to easily search in the current source tree for customized sys.mk files +(e.g., by using +.Qq \&.../mk/sys.mk +as an argument). +.It Fl n +Display the commands that would have been executed, but do not +actually execute them unless the target depends on the .MAKE special +source (see below). +.It Fl N +Display the commands which would have been executed, but do not +actually execute any of them; useful for debugging top-level makefiles +without descending into subdirectories. +.It Fl q +Do not execute any commands, but exit 0 if the specified targets are +up-to-date and 1, otherwise. +.It Fl r +Do not use the built-in rules specified in the system makefile. +.It Fl s +Do not echo any commands as they are executed. +Equivalent to specifying +.Ql Ic @ +before each command line in the makefile. +.It Fl T Ar tracefile +When used with the +.Fl j +flag, +append a trace record to +.Ar tracefile +for each job started and completed. +.It Fl t +Rather than re-building a target as specified in the makefile, create it +or update its modification time to make it appear up-to-date. +.It Fl V Ar variable +Print +.Nm Ns 's +idea of the value of +.Ar variable , +in the global context. +Do not build any targets. +Multiple instances of this option may be specified; +the variables will be printed one per line, +with a blank line for each null or undefined variable. +If +.Ar variable +contains a +.Ql \&$ +then the value will be expanded before printing. +.It Fl W +Treat any warnings during makefile parsing as errors. +.It Fl X +Don't export variables passed on the command line to the environment +individually. +Variables passed on the command line are still exported +via the +.Va MAKEFLAGS +environment variable. +This option may be useful on systems which have a small limit on the +size of command arguments. +.It Ar variable=value +Set the value of the variable +.Ar variable +to +.Ar value . +Normally, all values passed on the command line are also exported to +sub-makes in the environment. +The +.Fl X +flag disables this behavior. +Variable assignments should follow options for POSIX compatibility +but no ordering is enforced. +.El +.Pp +There are seven different types of lines in a makefile: file dependency +specifications, shell commands, variable assignments, include statements, +conditional directives, for loops, and comments. +.Pp +In general, lines may be continued from one line to the next by ending +them with a backslash +.Pq Ql \e . +The trailing newline character and initial whitespace on the following +line are compressed into a single space. +.Sh FILE DEPENDENCY SPECIFICATIONS +Dependency lines consist of one or more targets, an operator, and zero +or more sources. +This creates a relationship where the targets +.Dq depend +on the sources +and are usually created from them. +The exact relationship between the target and the source is determined +by the operator that separates them. +The three operators are as follows: +.Bl -tag -width flag +.It Ic \&: +A target is considered out-of-date if its modification time is less than +those of any of its sources. +Sources for a target accumulate over dependency lines when this operator +is used. +The target is removed if +.Nm +is interrupted. +.It Ic \&! +Targets are always re-created, but not until all sources have been +examined and re-created as necessary. +Sources for a target accumulate over dependency lines when this operator +is used. +The target is removed if +.Nm +is interrupted. +.It Ic \&:: +If no sources are specified, the target is always re-created. +Otherwise, a target is considered out-of-date if any of its sources has +been modified more recently than the target. +Sources for a target do not accumulate over dependency lines when this +operator is used. +The target will not be removed if +.Nm +is interrupted. +.El +.Pp +Targets and sources may contain the shell wildcard values +.Ql \&? , +.Ql * , +.Ql [] , +and +.Ql {} . +The values +.Ql \&? , +.Ql * , +and +.Ql [] +may only be used as part of the final +component of the target or source, and must be used to describe existing +files. +The value +.Ql {} +need not necessarily be used to describe existing files. +Expansion is in directory order, not alphabetically as done in the shell. +.Sh SHELL COMMANDS +Each target may have associated with it a series of shell commands, normally +used to create the target. +Each of the commands in this script +.Em must +be preceded by a tab. +While any target may appear on a dependency line, only one of these +dependencies may be followed by a creation script, unless the +.Ql Ic \&:: +operator is used. +.Pp +If the first characters of the command line are any combination of +.Ql Ic @ , +.Ql Ic + , +or +.Ql Ic \- , +the command is treated specially. +A +.Ql Ic @ +causes the command not to be echoed before it is executed. +A +.Ql Ic + +causes the command to be executed even when +.Fl n +is given. +This is similar to the effect of the .MAKE special source, +except that the effect can be limited to a single line of a script. +A +.Ql Ic \- +causes any non-zero exit status of the command line to be ignored. +.Pp +When +.Nm +is run in jobs mode with +.Fl j Ar max_jobs , +the entire script for the target is fed to a +single instance of the shell. +.Pp +In compatibility (non-jobs) mode, each command is run in a separate process. +If the command contains any shell meta characters +.Pq Ql #=|^(){};&<>*?[]:$`\e\en +it will be passed to the shell, otherwise +.Nm +will attempt direct execution. +.Pp +Since +.Nm +will +.Xr chdir 2 +to +.Ql Va .OBJDIR +before executing any targets, each child process +starts with that as its current working directory. +.Pp +Makefiles should be written so that the mode of +.Nm +operation does not change their behavior. +For example, any command which needs to use +.Dq cd +or +.Dq chdir , +without side-effect should be put in parenthesis: +.Bd -literal -offset indent + +avoid-chdir-side-effects: + @echo Building $@ in `pwd` + @(cd ${.CURDIR} && ${.MAKE} $@) + @echo Back in `pwd` + +ensure-one-shell-regardless-of-mode: + @echo Building $@ in `pwd`; \\ + (cd ${.CURDIR} && ${.MAKE} $@); \\ + echo Back in `pwd` +.Ed +.Sh VARIABLE ASSIGNMENTS +Variables in make are much like variables in the shell, and, by tradition, +consist of all upper-case letters. +.Ss Variable assignment modifiers +The five operators that can be used to assign values to variables are as +follows: +.Bl -tag -width Ds +.It Ic \&= +Assign the value to the variable. +Any previous value is overridden. +.It Ic \&+= +Append the value to the current value of the variable. +.It Ic \&?= +Assign the value to the variable if it is not already defined. +.It Ic \&:= +Assign with expansion, i.e. expand the value before assigning it +to the variable. +Normally, expansion is not done until the variable is referenced. +.Em NOTE : +References to undefined variables are +.Em not +expanded. +This can cause problems when variable modifiers are used. +.It Ic \&!= +Expand the value and pass it to the shell for execution and assign +the result to the variable. +Any newlines in the result are replaced with spaces. +.El +.Pp +Any white-space before the assigned +.Ar value +is removed; if the value is being appended, a single space is inserted +between the previous contents of the variable and the appended value. +.Pp +Variables are expanded by surrounding the variable name with either +curly braces +.Pq Ql {} +or parentheses +.Pq Ql () +and preceding it with +a dollar sign +.Pq Ql \&$ . +If the variable name contains only a single letter, the surrounding +braces or parentheses are not required. +This shorter form is not recommended. +.Pp +If the variable name contains a dollar, then the name itself is expanded first. +This allows almost arbitrary variable names, however names containing dollar, +braces, parenthesis, or whitespace are really best avoided! +.Pp +If the result of expanding a variable contains a dollar sign +.Pq Ql \&$ +the string is expanded again. +.Pp +Variable substitution occurs at three distinct times, depending on where +the variable is being used. +.Bl -enum +.It +Variables in dependency lines are expanded as the line is read. +.It +Variables in shell commands are expanded when the shell command is +executed. +.It +.Dq .for +loop index variables are expanded on each loop iteration. +Note that other variables are not expanded inside loops so +the following example code: +.Bd -literal -offset indent + +.Dv .for i in 1 2 3 +a+= ${i} +j= ${i} +b+= ${j} +.Dv .endfor + +all: + @echo ${a} + @echo ${b} + +.Ed +will print: +.Bd -literal -offset indent +1 2 3 +3 3 3 + +.Ed +Because while ${a} contains +.Dq 1 2 3 +after the loop is executed, ${b} +contains +.Dq ${j} ${j} ${j} +which expands to +.Dq 3 3 3 +since after the loop completes ${j} contains +.Dq 3 . +.El +.Ss Variable classes +The four different classes of variables (in order of increasing precedence) +are: +.Bl -tag -width Ds +.It Environment variables +Variables defined as part of +.Nm Ns 's +environment. +.It Global variables +Variables defined in the makefile or in included makefiles. +.It Command line variables +Variables defined as part of the command line. +.It Local variables +Variables that are defined specific to a certain target. +The seven local variables are as follows: +.Bl -tag -width ".ARCHIVE" +.It Va .ALLSRC +The list of all sources for this target; also known as +.Ql Va \&\*[Gt] . +.It Va .ARCHIVE +The name of the archive file. +.It Va .IMPSRC +In suffix-transformation rules, the name/path of the source from which the +target is to be transformed (the +.Dq implied +source); also known as +.Ql Va \&\*[Lt] . +It is not defined in explicit rules. +.It Va .MEMBER +The name of the archive member. +.It Va .OODATE +The list of sources for this target that were deemed out-of-date; also +known as +.Ql Va \&? . +.It Va .PREFIX +The file prefix of the target, containing only the file portion, no suffix +or preceding directory components; also known as +.Ql Va * . +.It Va .TARGET +The name of the target; also known as +.Ql Va @ . +.El +.Pp +The shorter forms +.Ql Va @ , +.Ql Va \&? , +.Ql Va \&\*[Lt] , +.Ql Va \&\*[Gt] , +and +.Ql Va * +are permitted for backward +compatibility with historical makefiles and are not recommended. +The six variables +.Ql Va "@F" , +.Ql Va "@D" , +.Ql Va "\*[Lt]F" , +.Ql Va "\*[Lt]D" , +.Ql Va "*F" , +and +.Ql Va "*D" +are permitted for compatibility with +.At V +makefiles and are not recommended. +.Pp +Four of the local variables may be used in sources on dependency lines +because they expand to the proper value for each target on the line. +These variables are +.Ql Va .TARGET , +.Ql Va .PREFIX , +.Ql Va .ARCHIVE , +and +.Ql Va .MEMBER . +.El +.Ss Additional built-in variables +In addition, +.Nm +sets or knows about the following variables: +.Bl -tag -width .MAKEOVERRIDES +.It Va \&$ +A single dollar sign +.Ql \&$ , +i.e. +.Ql \&$$ +expands to a single dollar +sign. +.It Va .ALLTARGETS +The list of all targets encountered in the Makefile. +If evaluated during +Makefile

+The recursion depth of +.Nm . +The initial instance of +.Nm +will be 0, and an incremented value is put into the environment +to be seen by the next generation. +This allows tests like: +.Li .if

Multiple makefiles may + be specified, and are read in the order specified. + + --II _d_i_r_e_c_t_o_r_y + Specify a directory in which to search for makefiles and included + makefiles. The system makefile directory (or directories, see + the --mm option) is automatically included as part of this list. + + --ii Ignore non-zero exit of shell commands in the makefile. Equiva- + lent to specifying `--' before each command line in the makefile. + + --JJ _p_r_i_v_a_t_e + This option should _n_o_t be specified by the user. + + When the _j option is in use in a recursive build, this option is + passed by a make to child makes to allow all the make processes + in the build to cooperate to avoid overloading the system. + + --jj _m_a_x___j_o_b_s + Specify the maximum number of jobs that bbmmaakkee may have running at + any one time. The value is saved in _._M_A_K_E_._J_O_B_S. Turns compati- + bility mode off, unless the _B flag is also specified.

This can break traditional + scripts which change directories on each command invocation and + then expect to start with a fresh environment on the next line. + It is more efficient to correct the scripts rather than turn + backwards compatibility on. + + --kk Continue processing after errors are encountered, but only on + those targets that do not depend on the target whose creation + caused the error. + + --mm _d_i_r_e_c_t_o_r_y + Specify a directory in which to search for sys.mk and makefiles + included via the <_f_i_l_e>-style include statement. The --mm option + can be used multiple times to form a search path. This path will + override the default system include path: /usr/share/mk. Fur- + thermore the system include path will be appended to the search + path used for "_f_i_l_e"-style include statements (see the --II + option). + + If a file or directory name in the --mm argument (or the + MAKESYSPATH environment variable) starts with the string ".../" + then bbmmaakkee will search for the specified file or directory named + in the remaining part of the argument string. The search starts + with the current directory of the Makefile and then works upward + towards the root of the filesystem. If the search is successful, + then the resulting directory replaces the ".../" specification in + the --mm argument. If used, this feature allows bbmmaakkee to easily + search in the current source tree for customized sys.mk files + (e.g., by using ".../mk/sys.mk" as an argument). + + --nn Display the commands that would have been executed, but do not + actually execute them unless the target depends on the .MAKE spe- + cial source (see below). + + --NN Display the commands which would have been executed, but do not + actually execute any of them; useful for debugging top-level + makefiles without descending into subdirectories. + + --qq Do not execute any commands, but exit 0 if the specified targets + are up-to-date and 1, otherwise. + + --rr Do not use the built-in rules specified in the system makefile. + + --ss Do not echo any commands as they are executed.

Do not build any targets. Multiple instances of this + option may be specified; the variables will be printed one per + line, with a blank line for each null or undefined variable. If + _v_a_r_i_a_b_l_e contains a `$' then the value will be expanded before + printing. + + --WW Treat any warnings during makefile parsing as errors. + + --XX Don't export variables passed on the command line to the environ- + ment individually. Variables passed on the command line are + still exported via the _M_A_K_E_F_L_A_G_S environment variable. This + option may be useful on systems which have a small limit on the + size of command arguments. + + _v_a_r_i_a_b_l_e_=_v_a_l_u_e + Set the value of the variable _v_a_r_i_a_b_l_e to _v_a_l_u_e. Normally, all + values passed on the command line are also exported to sub-makes + in the environment. The --XX flag disables this behavior. Vari- + able assignments should follow options for POSIX compatibility + but no ordering is enforced. + + There are seven different types of lines in a makefile: file dependency + specifications, shell commands, variable assignments, include statements, + conditional directives, for loops, and comments. + + In general, lines may be continued from one line to the next by ending + them with a backslash (`\'). The trailing newline character and initial + whitespace on the following line are compressed into a single space. + +FFIILLEE DDEEPPEENNDDEENNCCYY SSPPEECCIIFFIICCAATTIIOONNSS + Dependency lines consist of one or more targets, an operator, and zero or + more sources. This creates a relationship where the targets ``depend'' + on the sources and are usually created from them. The exact relationship + between the target and the source is determined by the operator that sep- + arates them. The three operators are as follows: + + :: A target is considered out-of-date if its modification time is less + than those of any of its sources. Sources for a target accumulate + over dependency lines when this operator is used. The target is + removed if bbmmaakkee is interrupted. + + !! Targets are always re-created, but not until all sources have been + examined and re-created as necessary. Sources for a target accumu- + late over dependency lines when this operator is used. The target + is removed if bbmmaakkee is interrupted. + + :::: If no sources are specified, the target is always re-created. Oth- + erwise, a target is considered out-of-date if any of its sources + has been modified more recently than the target. Sources for a + target do not accumulate over dependency lines when this operator + is used. The target will not be removed if bbmmaakkee is interrupted. + + Targets and sources may contain the shell wildcard values `?', `*', `[]', + and `{}'. The values `?', `*', and `[]' may only be used as part of the + final component of the target or source, and must be used to describe + existing files. The value `{}' need not necessarily be used to describe + existing files. Expansion is in directory order, not alphabetically as + done in the shell. + +SSHHEELLLL CCOOMMMMAANNDDSS + Each target may have associated with it a series of shell commands, nor- + mally used to create the target. Each of the commands in this script + _m_u_s_t be preceded by a tab. While any target may appear on a dependency + line, only one of these dependencies may be followed by a creation + script, unless the `::::' operator is used. + + If the first characters of the command line are any combination of `@@', + `++', or `--', the command is treated specially. A `@@' causes the command + not to be echoed before it is executed. A `++' causes the command to be + executed even when --nn is given. This is similar to the effect of the + .MAKE special source, except that the effect can be limited to a single + line of a script. A `--' causes any non-zero exit status of the command + line to be ignored. + + When bbmmaakkee is run in jobs mode with --jj _m_a_x___j_o_b_s, the entire script for + the target is fed to a single instance of the shell. + + In compatibility (non-jobs) mode, each command is run in a separate + process. If the command contains any shell meta characters + (`#=|^(){};&<>*?[]:$`\\n') it will be passed to the shell, otherwise + bbmmaakkee will attempt direct execution. + + Since bbmmaakkee will chdir(2) to `_._O_B_J_D_I_R' before executing any targets, each + child process starts with that as its current working directory. + + Makefiles should be written so that the mode of bbmmaakkee operation does not + change their behavior. For example, any command which needs to use + ``cd'' or ``chdir'', without side-effect should be put in parenthesis: + + + avoid-chdir-side-effects: + @echo Building $@ in `pwd` + @(cd ${.CURDIR} && ${.MAKE} $@) + @echo Back in `pwd` + + ensure-one-shell-regardless-of-mode: + @echo Building $@ in `pwd`; \ + (cd ${.CURDIR} && ${.MAKE} $@); \ + echo Back in `pwd` + +VVAARRIIAABBLLEE AASSSSIIGGNNMMEENNTTSS + Variables in make are much like variables in the shell, and, by tradi- + tion, consist of all upper-case letters. + + VVaarriiaabbllee aassssiiggnnmmeenntt mmooddiiffiieerrss + The five operators that can be used to assign values to variables are as + follows: + + == Assign the value to the variable. Any previous value is overrid- + den. + + ++== Append the value to the current value of the variable. + + ??== Assign the value to the variable if it is not already defined. + + ::== Assign with expansion, i.e. expand the value before assigning it + to the variable. Normally, expansion is not done until the vari- + able is referenced. _N_O_T_E: References to undefined variables are + _n_o_t expanded. This can cause problems when variable modifiers + are used. + + !!== Expand the value and pass it to the shell for execution and + assign the result to the variable. Any newlines in the result + are replaced with spaces. + + Any white-space before the assigned _v_a_l_u_e is removed; if the value is + being appended, a single space is inserted between the previous contents + of the variable and the appended value. + + Variables are expanded by surrounding the variable name with either curly + braces (`{}') or parentheses (`()') and preceding it with a dollar sign + (`$'). If the variable name contains only a single letter, the surround- + ing braces or parentheses are not required. This shorter form is not + recommended. + + If the variable name contains a dollar, then the name itself is expanded + first. This allows almost arbitrary variable names, however names con- + taining dollar, braces, parenthesis, or whitespace are really best + avoided! + + If the result of expanding a variable contains a dollar sign (`$') the + string is expanded again. + + Variable substitution occurs at three distinct times, depending on where + the variable is being used. + + 1. Variables in dependency lines are expanded as the line is read. + + 2. Variables in shell commands are expanded when the shell command is + executed. + + 3. ``.for'' loop index variables are expanded on each loop iteration. + Note that other variables are not expanded inside loops so the fol- + lowing example code: + + + .for i in 1 2 3 + a+= ${i} + j= ${i} + b+= ${j} + .endfor + + all: + @echo ${a} + @echo ${b} + + will print: + + 1 2 3 + 3 3 3 + + Because while ${a} contains ``1 2 3'' after the loop is executed, + ${b} contains ``${j} ${j} ${j}'' which expands to ``3 3 3'' since + after the loop completes ${j} contains ``3''. + + VVaarriiaabbllee ccllaasssseess + The four different classes of variables (in order of increasing prece- + dence) are: + + Environment variables + Variables defined as part of bbmmaakkee's environment. + + Global variables + Variables defined in the makefile or in included makefiles. + + Command line variables + Variables defined as part of the command line. + + Local variables + Variables that are defined specific to a certain target. The + seven local variables are as follows: + + _._A_L_L_S_R_C The list of all sources for this target; also known as + `_>'. + + _._A_R_C_H_I_V_E The name of the archive file. + + _._I_M_P_S_R_C In suffix-transformation rules, the name/path of the + source from which the target is to be transformed (the + ``implied'' source); also known as `_<'. It is not + defined in explicit rules. + + _._M_E_M_B_E_R The name of the archive member. + + _._O_O_D_A_T_E The list of sources for this target that were deemed + out-of-date; also known as `_?'. + + _._P_R_E_F_I_X The file prefix of the target, containing only the file + portion, no suffix or preceding directory components; + also known as `_*'. + + _._T_A_R_G_E_T The name of the target; also known as `_@'. + + The shorter forms `_@', `_?', `_<', `_>', and `_*' are permitted for + backward compatibility with historical makefiles and are not rec- + ommended. The six variables `_@_F', `_@_D', `_<_F', `_<_D', `_*_F', and + `_*_D' are permitted for compatibility with AT&T System V UNIX + makefiles and are not recommended. + + Four of the local variables may be used in sources on dependency + lines because they expand to the proper value for each target on + the line. These variables are `_._T_A_R_G_E_T', `_._P_R_E_F_I_X', `_._A_R_C_H_I_V_E', + and `_._M_E_M_B_E_R'. + + AAddddiittiioonnaall bbuuiilltt--iinn vvaarriiaabblleess + In addition, bbmmaakkee sets or knows about the following variables: + + _$ A single dollar sign `$', i.e. `$$' expands to a single + dollar sign. + + _._A_L_L_T_A_R_G_E_T_S The list of all targets encountered in the Makefile.

The captured + output can be very useful when diagnosing + errors. + + _c_u_r_d_i_r_O_k_= _b_f Normally bbmmaakkee will not create .meta files + in `_._C_U_R_D_I_R'.

This is useful if the + build is otherwise running silently. The + message printed the value of: + _._M_A_K_E_._M_E_T_A_._P_R_E_F_I_X. + + _i_g_n_o_r_e_-_c_m_d Some makefiles have commands which are simply + not stable.

The default value is: + Building ${.TARGET:H:tA}/${.TARGET:T} + + _._M_A_K_E_O_V_E_R_R_I_D_E_S This variable is used to record the names of variables + assigned to on the command line, so that they may be + exported as part of `MAKEFLAGS'. This behaviour can be + disabled by assigning an empty value to `_._M_A_K_E_O_V_E_R_R_I_D_E_S' + within a makefile. Extra variables can be exported from + a makefile by appending their names to `_._M_A_K_E_O_V_E_R_R_I_D_E_S'. + `MAKEFLAGS' is re-exported whenever `_._M_A_K_E_O_V_E_R_R_I_D_E_S' is + modified. + + _._M_A_K_E_._P_I_D The process-id of bbmmaakkee. + + _._M_A_K_E_._P_P_I_D The parent process-id of bbmmaakkee. + + _M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R + When bbmmaakkee stops due to an error, it prints its name and + the value of `_._C_U_R_D_I_R' as well as the value of any vari- + ables named in `_M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R'. + + _._n_e_w_l_i_n_e This variable is simply assigned a newline character as + its value. This allows expansions using the ::@@ modifier + to put a newline between iterations of the loop rather + than a space. For example, the printing of + `_M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R' could be done as + ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}. + + _._O_B_J_D_I_R A path to the directory where the targets are built.

This is especially useful with + `MAKEOBJDIR'. + + `_._O_B_J_D_I_R' may be modified in the makefile as a global + variable. In all cases, bbmmaakkee will chdir(2) to `_._O_B_J_D_I_R' + and set `PWD' to that directory before executing any tar- + gets. + + _._P_A_R_S_E_D_I_R A path to the directory of the current `_M_a_k_e_f_i_l_e' being + parsed. + + _._P_A_R_S_E_F_I_L_E The basename of the current `_M_a_k_e_f_i_l_e' being parsed. + This variable and `_._P_A_R_S_E_D_I_R' are both set only while the + `_M_a_k_e_f_i_l_e_s' are being parsed. If you want to retain + their current values, assign them to a variable using + assignment with expansion: (`::=='). + + _._P_A_T_H A variable that represents the list of directories that + bbmmaakkee will search for files. The search list should be + updated using the target `_._P_A_T_H' rather than the vari- + able. + + PWD Alternate path to the current directory. bbmmaakkee normally + sets `_._C_U_R_D_I_R' to the canonical path given by getcwd(3). + However, if the environment variable `PWD' is set and + gives a path to the current directory, then bbmmaakkee sets + `_._C_U_R_D_I_R' to the value of `PWD' instead. This behaviour + is disabled if `MAKEOBJDIRPREFIX' is set or `MAKEOBJDIR' + contains a variable transform. `PWD' is set to the value + of `_._O_B_J_D_I_R' for all programs which bbmmaakkee executes. + + .TARGETS The list of targets explicitly specified on the command + line, if any. + + VPATH Colon-separated (``:'') lists of directories that bbmmaakkee + will search for files. The variable is supported for + compatibility with old make programs only, use `_._P_A_T_H' + instead. + + VVaarriiaabbllee mmooddiiffiieerrss + Variable expansion may be modified to select or modify each word of the + variable (where a ``word'' is white-space delimited sequence of charac- + ters). The general format of a variable expansion is as follows: + + ${variable[:modifier[:...]]} + + Each modifier begins with a colon, which may be escaped with a backslash + (`\'). + + A set of modifiers can be specified via a variable, as follows: + + modifier_variable=modifier[:...] + ${variable:${modifier_variable}[:...]} + + In this case the first modifier in the modifier_variable does not start + with a colon, since that must appear in the referencing variable. If any + of the modifiers in the modifier_variable contain a dollar sign (`$'), + these must be doubled to avoid early expansion. + + The supported modifiers are: + + ::EE Replaces each word in the variable with its suffix. + + ::HH Replaces each word in the variable with everything but the last com- + ponent. + + ::MM_p_a_t_t_e_r_n + Select only those words that match _p_a_t_t_e_r_n. The standard shell + wildcard characters (`*', `?', and `[]') may be used.

To sort words in + reverse order use the `::OO::[[--11....11]]' combination of modifiers. + + ::OOxx Randomize words in variable. The results will be different each + time you are referring to the modified variable; use the assignment + with expansion (`::==') to prevent such behaviour.

This modifier sets the separator to the character _c. If _c is + omitted, then no separator is used. The common escapes (including + octal numeric codes), work as expected. + + ::ttuu Converts variable to upper-case letters. + + ::ttWW Causes the value to be treated as a single word (possibly containing + embedded white space). See also `::[[**]]'. + + ::ttww Causes the value to be treated as a sequence of words delimited by + white space. See also `::[[@@]]'. + + ::SS/_o_l_d___s_t_r_i_n_g/_n_e_w___s_t_r_i_n_g/[11ggWW] + Modify the first occurrence of _o_l_d___s_t_r_i_n_g in the variable's value, + replacing it with _n_e_w___s_t_r_i_n_g. If a `g' is appended to the last + slash of the pattern, all occurrences in each word are replaced. If + a `1' is appended to the last slash of the pattern, only the first + word is affected. If a `W' is appended to the last slash of the + pattern, then the value is treated as a single word (possibly con- + taining embedded white space). If _o_l_d___s_t_r_i_n_g begins with a caret + (`^'), _o_l_d___s_t_r_i_n_g is anchored at the beginning of each word. If + _o_l_d___s_t_r_i_n_g ends with a dollar sign (`$'), it is anchored at the end + of each word. Inside _n_e_w___s_t_r_i_n_g, an ampersand (`&') is replaced by + _o_l_d___s_t_r_i_n_g (without any `^' or `$'). Any character may be used as a + delimiter for the parts of the modifier string. The anchoring, + ampersand and delimiter characters may be escaped with a backslash + (`\'). + + Variable expansion occurs in the normal fashion inside both + _o_l_d___s_t_r_i_n_g and _n_e_w___s_t_r_i_n_g with the single exception that a backslash + is used to prevent the expansion of a dollar sign (`$'), not a pre- + ceding dollar sign as is usual. + + ::CC/_p_a_t_t_e_r_n/_r_e_p_l_a_c_e_m_e_n_t/[11ggWW] + The ::CC modifier is just like the ::SS modifier except that the old and + new strings, instead of being simple strings, are a regular expres- + sion (see regex(3)) string _p_a_t_t_e_r_n and an ed(1)-style string + _r_e_p_l_a_c_e_m_e_n_t. Normally, the first occurrence of the pattern _p_a_t_t_e_r_n + in each word of the value is substituted with _r_e_p_l_a_c_e_m_e_n_t. The `1' + modifier causes the substitution to apply to at most one word; the + `g' modifier causes the substitution to apply to as many instances + of the search pattern _p_a_t_t_e_r_n as occur in the word or words it is + found in; the `W' modifier causes the value to be treated as a sin- + gle word (possibly containing embedded white space). Note that `1' + and `g' are orthogonal; the former specifies whether multiple words + are potentially affected, the latter whether multiple substitutions + can potentially occur within each affected word. + + ::TT Replaces each word in the variable with its last component. + + ::uu Remove adjacent duplicate words (like uniq(1)). + + ::??_t_r_u_e___s_t_r_i_n_g::_f_a_l_s_e___s_t_r_i_n_g + If the variable name (not its value), when parsed as a .if condi- + tional expression, evaluates to true, return as its value the + _t_r_u_e___s_t_r_i_n_g, otherwise return the _f_a_l_s_e___s_t_r_i_n_g. Since the variable + name is used as the expression, :? must be the first modifier after + the variable name itself - which will, of course, usually contain + variable expansions. A common error is trying to use expressions + like + ${NUMBERS:M42:?match:no} + which actually tests defined(NUMBERS), to determine is any words + match "42" you need to use something like: + ${"${NUMBERS:M42}" != "":?match:no}. + + _:_o_l_d___s_t_r_i_n_g_=_n_e_w___s_t_r_i_n_g + This is the AT&T System V UNIX style variable substitution.

If _o_l_d___s_t_r_i_n_g or _n_e_w___s_t_r_i_n_g do not + contain the pattern matching character _% then it is assumed that + they are anchored at the end of each word, so only suffixes or + entire words may be replaced. Otherwise _% is the substring of + _o_l_d___s_t_r_i_n_g to be replaced in _n_e_w___s_t_r_i_n_g. + + Variable expansion occurs in the normal fashion inside both + _o_l_d___s_t_r_i_n_g and _n_e_w___s_t_r_i_n_g with the single exception that a backslash + is used to prevent the expansion of a dollar sign (`$'), not a pre- + ceding dollar sign as is usual. + + ::@@_t_e_m_p@@_s_t_r_i_n_g@@ + This is the loop expansion mechanism from the OSF Development Envi- + ronment (ODE) make.

Some modifiers suppress this behaviour, causing a + value to be treated as a single word (possibly containing embedded + white space). An empty value, or a value that consists entirely of + white-space, is treated as a single word. For the purposes of the + `::[[]]' modifier, the words are indexed both forwards using positive + integers (where index 1 represents the first word), and backwards + using negative integers (where index -1 represents the last word). + + The _r_a_n_g_e is subjected to variable expansion, and the expanded + result is then interpreted as follows: + + _i_n_d_e_x Selects a single word from the value. + + _s_t_a_r_t...._e_n_d + Selects all words from _s_t_a_r_t to _e_n_d, inclusive. For example, + `::[[22....--11]]' selects all words from the second word to the last + word. If _s_t_a_r_t is greater than _e_n_d, then the words are out- + put in reverse order.

If no relational operator is given, it + is assumed that the expanded variable is being compared against 0 or an + empty string in the case of a string comparison. + + When bbmmaakkee is evaluating one of these conditional expressions, and it + encounters a (white-space separated) word it doesn't recognize, either + the ``make'' or ``defined'' expression is applied to it, depending on the + form of the conditional. If the form is `..iiffddeeff', `..iiffnnddeeff', or `..iiff' + the ``defined'' expression is applied. Similarly, if the form is + `..iiffmmaakkee' or `..iiffnnmmaakkee, tthhee' ``make'' expression is applied. + + If the conditional evaluates to true the parsing of the makefile contin- + ues as before. If it evaluates to false, the following lines are + skipped. In both cases this continues until a `..eellssee' or `..eennddiiff' is + found. + + For loops are typically used to apply a set of rules to a list of files. + The syntax of a for loop is: + + ..ffoorr _v_a_r_i_a_b_l_e [_v_a_r_i_a_b_l_e _._._.] iinn _e_x_p_r_e_s_s_i_o_n + <make-rules> + ..eennddffoorr + + After the for eexxpprreessssiioonn is evaluated, it is split into words. On each + iteration of the loop, one word is taken and assigned to each vvaarriiaabbllee, + in order, and these vvaarriiaabblleess are substituted into the mmaakkee--rruulleess inside + the body of the for loop. The number of words must come out even; that + is, if there are three iteration variables, the number of words provided + must be a multiple of three. + +CCOOMMMMEENNTTSS + Comments begin with a hash (`#') character, anywhere but in a shell com- + mand line, and continue to the end of an unescaped new line. + +SSPPEECCIIAALL SSOOUURRCCEESS ((AATTTTRRIIBBUUTTEESS)) + ..EEXXEECC Target is never out of date, but always execute commands any- + way. + + ..IIGGNNOORREE Ignore any errors from the commands associated with this tar- + get, exactly as if they all were preceded by a dash (`-'). + + ..MMAADDEE Mark all sources of this target as being up-to-date. + + ..MMAAKKEE Execute the commands associated with this target even if the --nn + or --tt options were specified.

Suffix-transformation rules are not applied to + ..PPHHOONNYY targets. + + ..PPRREECCIIOOUUSS + When bbmmaakkee is interrupted, it normally removes any partially + made targets.

When the tar- + get is used as a source for another target, the other target + acquires the commands, sources, and attributes (except for + ..UUSSEE) of the source.

So given: + + x: a .WAIT b + echo x + a: + echo a + b: b1 + echo b + b1: + echo b1 + + the output is always `a', `b1', `b', `x'. + The ordering imposed by ..WWAAIITT is only relevant for parallel + makes. + +SSPPEECCIIAALL TTAARRGGEETTSS + Special targets may not be included with other targets, i.e. they must be + the only target specified. + + ..BBEEGGIINN Any command lines attached to this target are executed before + anything else is done. + + ..DDEEFFAAUULLTT + This is sort of a ..UUSSEE rule for any target (that was used only + as a source) that bbmmaakkee can't figure out any other way to cre- + ate.

It was designed to be a parallel distributed make running jobs + on different machines using a daemon called ``customs''. + +BBUUGGSS + The make syntax is difficult to parse without actually acting of the + data. For instance finding the end of a variable use should involve + scanning each the modifiers using the correct terminator for each field. + In many places make just counts {} and () in order to find the end of a + variable expansion. + + There is no way of escaping a space character in a filename. + +NetBSD 5.1 January 23, 2013 NetBSD 5.1 diff --git a/20130123/boot-strap b/20130123/boot-strap new file mode 100755 index 0000000..7eff5f6 --- /dev/null +++ b/20130123/boot-strap @@ -0,0 +1,461 @@ +: +# NAME: +# boot-strap +# +# SYNOPSIS: +# boot-strap ["options"] +# boot-strap --prefix=/opt --install +# boot-strap --prefix=$HOME --install-host-target -DWITH_PROG_VERSION +# boot-strap ["options"] op=build +# boot-strap ["options"] op=install +# +# DESCRIPTION: +# This script is used to configure/build bmake it builds for +# each host-target in a different subdir to keep the src clean. +# There is no requirement for an existing make(1). +# +# On successful completion if no '--install' flag is given, +# it echos a command to do installation. +# +# The variable "op" defaults to 'all', and is affected by +# '--install' flag as above. +# Other values include: +# +# configure +# Just run 'configure' +# +# build +# If 'configure' has not been done, do it, then +# run the build script, and finally 'test'. +# +# install +# If 'build' has not been done, do it, 'test' then +# install. +# +# clean +# attempt to clean up +# +# test +# run the unit-tests.

A Path structure + * has in it the name of the directory and a hash table of all the files + * in the directory. This is used to cut down on the number of system + * calls necessary to find implicit dependents and their like. Since + * these searches are made before any actions are taken, we need not + * worry about the directory changing due to creation commands. If this + * hampers the style of some makefiles, they must be changed. + * + * A list of all previously-read directories is kept in the + * openDirectories Lst. This list is checked first before a directory + * is opened. + * + * The need for the caching of whole directories is brought about by + * the multi-level transformation code in suff.c, which tends to search + * for far more files than regular make does. In the initial + * implementation, the amount of time spent performing "stat" calls was + * truly astronomical. The problem with hashing at the start is, + * of course, that pmake doesn't then detect changes to these directories + * during the course of the make. Three possibilities suggest themselves: + * + * 1) just use stat to test for a file's existence. As mentioned + * above, this is very inefficient due to the number of checks + * engendered by the multi-level transformation code. + * 2) use readdir() and company to search the directories, keeping + * them open between checks. I have tried this and while it + * didn't slow down the process too much, it could severely + * affect the amount of parallelism available as each directory + * open would take another file descriptor out of play for + * handling I/O for another job. Given that it is only recently + * that UNIX OS's have taken to allowing more than 20 or 32 + * file descriptors for a process, this doesn't seem acceptable + * to me. + * 3) record the mtime of the directory in the Path structure and + * verify the directory hasn't changed since the contents were + * hashed. This will catch the creation or deletion of files, + * but not the updating of files. However, since it is the + * creation and deletion that is the problem, this could be + * a good thing to do. Unfortunately, if the directory (say ".") + * were fairly large and changed fairly frequently, the constant + * rehashing could seriously degrade performance. It might be + * good in such cases to keep track of the number of rehashes + * and if the number goes over a (small) limit, resort to using + * stat in its place. + * + * An additional thing to consider is that pmake is used primarily + * to create C programs and until recently pcc-based compilers refused + * to allow you to specify where the resulting object file should be + * placed. This forced all objects to be created in the current + * directory. This isn't meant as a full excuse, just an explanation of + * some of the reasons for the caching used here. + * + * One more note: the location of a target's file is only performed + * on the downward traversal of the graph and then only for terminal + * nodes in the graph. This could be construed as wrong in some cases, + * but prevents inadvertent modification of files when the "installed" + * directory for a file is provided in the search path. + * + * Another data structure maintained by this module is an mtime + * cache used when the searching of cached directories fails to find + * a file. In the past, Dir_FindFile would simply perform an access() + * call in such a case to determine if the file could be found using + * just the name given. When this hit, however, all that was gained + * was the knowledge that the file existed. Given that an access() is + * essentially a stat() without the copyout() call, and that the same + * filesystem overhead would have to be incurred in Dir_MTime, it made + * sense to replace the access() with a stat() and record the mtime + * in a cache for when Dir_MTime was actually called. + */ + +Lst dirSearchPath; /* main search path */ + +static Lst openDirectories; /* the list of all open directories */ + +/* + * Variables for gathering statistics on the efficiency of the hashing + * mechanism. + */ +static int hits, /* Found in directory cache */ + misses, /* Sad, but not evil misses */ + nearmisses, /* Found under search path */ + bigmisses; /* Sought by itself */ + +static Path *dot; /* contents of current directory */ +static Path *cur; /* contents of current directory, if not dot */ +static Path *dotLast; /* a fake path entry indicating we need to + * look for . last */ +static Hash_Table mtimes; /* Results of doing a last-resort stat in + * Dir_FindFile -- if we have to go to the + * system to find the file, we might as well + * have its mtime on record.

+.Sh DESCRIPTION +.Nm +is a program designed to simplify the maintenance of other programs. +Its input is a list of specifications as to the files upon which programs +and other files depend. +If no +.Fl f Ar makefile +makefile option is given, +.Nm +will try to open +.Ql Pa makefile +then +.Ql Pa Makefile +in order to find the specifications. +If the file +.Ql Pa .depend +exists, it is read (see +.Xr mkdep 1 ) . +.Pp +This manual page is intended as a reference document only. +For a more thorough description of +.Nm +and makefiles, please refer to +.%T "PMake \- A Tutorial" . +.Pp +.Nm +will prepend the contents of the +.Va MAKEFLAGS +environment variable to the command line arguments before parsing them. +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl B +Try to be backwards compatible by executing a single shell per command and +by executing the commands to make the sources of a dependency line in sequence. +.It Fl C Ar directory +Change to +.Ar directory +before reading the makefiles or doing anything else. +If multiple +.Fl C +options are specified, each is interpreted relative to the previous one: +.Fl C Pa / Fl C Pa etc +is equivalent to +.Fl C Pa /etc . +.It Fl D Ar variable +Define +.Ar variable +to be 1, in the global context. +.It Fl d Ar [-]flags +Turn on debugging, and specify which portions of +.Nm +are to print debugging information. +Unless the flags are preceded by +.Ql \- +they are added to the +.Va MAKEFLAGS +environment variable and will be processed by any child make processes. +By default, debugging information is printed to standard error, +but this can be changed using the +.Ar F +debugging flag. +The debugging output is always unbuffered; in addition, if debugging +is enabled but debugging output is not directed to standard output, +then the standard output is line buffered. +.Ar Flags +is one or more of the following: +.Bl -tag -width Ds +.It Ar A +Print all possible debugging information; +equivalent to specifying all of the debugging flags. +.It Ar a +Print debugging information about archive searching and caching. +.It Ar C +Print debugging information about current working directory. +.It Ar c +Print debugging information about conditional evaluation. +.It Ar d +Print debugging information about directory searching and caching. +.It Ar e +Print debugging information about failed commands and targets. +.It Ar F Ns Oo Sy \&+ Oc Ns Ar filename +Specify where debugging output is written. +This must be the last flag, because it consumes the remainder of +the argument. +If the character immediately after the +.Ql F +flag is +.Ql \&+ , +then the file will be opened in append mode; +otherwise the file will be overwritten. +If the file name is +.Ql stdout +or +.Ql stderr +then debugging output will be written to the +standard output or standard error output file descriptors respectively +(and the +.Ql \&+ +option has no effect). +Otherwise, the output will be written to the named file. +If the file name ends +.Ql .%d +then the +.Ql %d +is replaced by the pid. +.It Ar f +Print debugging information about loop evaluation. +.It Ar "g1" +Print the input graph before making anything. +.It Ar "g2" +Print the input graph after making everything, or before exiting +on error. +.It Ar "g3" +Print the input graph before exiting on error. +.It Ar j +Print debugging information about running multiple shells. +.It Ar l +Print commands in Makefiles regardless of whether or not they are prefixed by +.Ql @ +or other "quiet" flags. +Also known as "loud" behavior. +.It Ar M +Print debugging information about "meta" mode decisions about targets. +.It Ar m +Print debugging information about making targets, including modification +dates. +.It Ar n +Don't delete the temporary command scripts created when running commands. +These temporary scripts are created in the directory +referred to by the +.Ev TMPDIR +environment variable, or in +.Pa /tmp +if +.Ev TMPDIR +is unset or set to the empty string. +The temporary scripts are created by +.Xr mkstemp 3 , +and have names of the form +.Pa makeXXXXXX . +.Em NOTE : +This can create many files in +.Ev TMPDIR +or +.Pa /tmp , +so use with care. +.It Ar p +Print debugging information about makefile parsing. +.It Ar s +Print debugging information about suffix-transformation rules. +.It Ar t +Print debugging information about target list maintenance. +.It Ar V +Force the +.Fl V +option to print raw values of variables. +.It Ar v +Print debugging information about variable assignment. +.It Ar x +Run shell commands with +.Fl x +so the actual commands are printed as they are executed. +.El +.It Fl e +Specify that environment variables override macro assignments within +makefiles. +.It Fl f Ar makefile +Specify a makefile to read instead of the default +.Ql Pa makefile . +If +.Ar makefile +is +.Ql Fl , +standard input is read. +Multiple makefiles may be specified, and are read in the order specified. +.It Fl I Ar directory +Specify a directory in which to search for makefiles and included makefiles. +The system makefile directory (or directories, see the +.Fl m +option) is automatically included as part of this list. +.It Fl i +Ignore non-zero exit of shell commands in the makefile. +Equivalent to specifying +.Ql Fl +before each command line in the makefile. +.It Fl J Ar private +This option should +.Em not +be specified by the user. +.Pp +When the +.Ar j +option is in use in a recursive build, this option is passed by a make +to child makes to allow all the make processes in the build to +cooperate to avoid overloading the system. +.It Fl j Ar max_jobs +Specify the maximum number of jobs that +.Nm +may have running at any one time. +The value is saved in +.Va .MAKE.JOBS . +Turns compatibility mode off, unless the +.Ar B +flag is also specified. +When compatibility mode is off, all commands associated with a +target are executed in a single shell invocation as opposed to the +traditional one shell invocation per line. +This can break traditional scripts which change directories on each +command invocation and then expect to start with a fresh environment +on the next line. +It is more efficient to correct the scripts rather than turn backwards +compatibility on. +.It Fl k +Continue processing after errors are encountered, but only on those targets +that do not depend on the target whose creation caused the error. +.It Fl m Ar directory +Specify a directory in which to search for sys.mk and makefiles included +via the +.Ao Ar file Ac Ns -style +include statement. +The +.Fl m +option can be used multiple times to form a search path. +This path will override the default system include path: /usr/share/mk. +Furthermore the system include path will be appended to the search path used +for +.Qo Ar file Qc Ns -style +include statements (see the +.Fl I +option). +.Pp +If a file or directory name in the +.Fl m +argument (or the +.Ev MAKESYSPATH +environment variable) starts with the string +.Qq \&.../ +then +.Nm +will search for the specified file or directory named in the remaining part +of the argument string. +The search starts with the current directory of +the Makefile and then works upward towards the root of the filesystem. +If the search is successful, then the resulting directory replaces the +.Qq \&.../ +specification in the +.Fl m +argument. +If used, this feature allows +.Nm +to easily search in the current source tree for customized sys.mk files +(e.g., by using +.Qq \&.../mk/sys.mk +as an argument). +.It Fl n +Display the commands that would have been executed, but do not +actually execute them unless the target depends on the .MAKE special +source (see below). +.It Fl N +Display the commands which would have been executed, but do not +actually execute any of them; useful for debugging top-level makefiles +without descending into subdirectories. +.It Fl q +Do not execute any commands, but exit 0 if the specified targets are +up-to-date and 1, otherwise. +.It Fl r +Do not use the built-in rules specified in the system makefile. +.It Fl s +Do not echo any commands as they are executed. +Equivalent to specifying +.Ql Ic @ +before each command line in the makefile. +.It Fl T Ar tracefile +When used with the +.Fl j +flag, +append a trace record to +.Ar tracefile +for each job started and completed. +.It Fl t +Rather than re-building a target as specified in the makefile, create it +or update its modification time to make it appear up-to-date. +.It Fl V Ar variable +Print +.Nm Ns 's +idea of the value of +.Ar variable , +in the global context. +Do not build any targets. +Multiple instances of this option may be specified; +the variables will be printed one per line, +with a blank line for each null or undefined variable. +If +.Ar variable +contains a +.Ql \&$ +then the value will be expanded before printing. +.It Fl W +Treat any warnings during makefile parsing as errors. +.It Fl X +Don't export variables passed on the command line to the environment +individually. +Variables passed on the command line are still exported +via the +.Va MAKEFLAGS +environment variable. +This option may be useful on systems which have a small limit on the +size of command arguments. +.It Ar variable=value +Set the value of the variable +.Ar variable +to +.Ar value . +Normally, all values passed on the command line are also exported to +sub-makes in the environment. +The +.Fl X +flag disables this behavior. +Variable assignments should follow options for POSIX compatibility +but no ordering is enforced. +.El +.Pp +There are seven different types of lines in a makefile: file dependency +specifications, shell commands, variable assignments, include statements, +conditional directives, for loops, and comments. +.Pp +In general, lines may be continued from one line to the next by ending +them with a backslash +.Pq Ql \e . +The trailing newline character and initial whitespace on the following +line are compressed into a single space. +.Sh FILE DEPENDENCY SPECIFICATIONS +Dependency lines consist of one or more targets, an operator, and zero +or more sources. +This creates a relationship where the targets +.Dq depend +on the sources +and are usually created from them. +The exact relationship between the target and the source is determined +by the operator that separates them. +The three operators are as follows: +.Bl -tag -width flag +.It Ic \&: +A target is considered out-of-date if its modification time is less than +those of any of its sources. +Sources for a target accumulate over dependency lines when this operator +is used. +The target is removed if +.Nm +is interrupted. +.It Ic \&! +Targets are always re-created, but not until all sources have been +examined and re-created as necessary. +Sources for a target accumulate over dependency lines when this operator +is used. +The target is removed if +.Nm +is interrupted. +.It Ic \&:: +If no sources are specified, the target is always re-created. +Otherwise, a target is considered out-of-date if any of its sources has +been modified more recently than the target. +Sources for a target do not accumulate over dependency lines when this +operator is used. +The target will not be removed if +.Nm +is interrupted. +.El +.Pp +Targets and sources may contain the shell wildcard values +.Ql \&? , +.Ql * , +.Ql [] , +and +.Ql {} . +The values +.Ql \&? , +.Ql * , +and +.Ql [] +may only be used as part of the final +component of the target or source, and must be used to describe existing +files. +The value +.Ql {} +need not necessarily be used to describe existing files. +Expansion is in directory order, not alphabetically as done in the shell. +.Sh SHELL COMMANDS +Each target may have associated with it a series of shell commands, normally +used to create the target. +Each of the commands in this script +.Em must +be preceded by a tab. +While any target may appear on a dependency line, only one of these +dependencies may be followed by a creation script, unless the +.Ql Ic \&:: +operator is used. +.Pp +If the first characters of the command line are any combination of +.Ql Ic @ , +.Ql Ic + , +or +.Ql Ic \- , +the command is treated specially. +A +.Ql Ic @ +causes the command not to be echoed before it is executed. +A +.Ql Ic + +causes the command to be executed even when +.Fl n +is given. +This is similar to the effect of the .MAKE special source, +except that the effect can be limited to a single line of a script. +A +.Ql Ic \- +causes any non-zero exit status of the command line to be ignored. +.Pp +When +.Nm +is run in jobs mode with +.Fl j Ar max_jobs , +the entire script for the target is fed to a +single instance of the shell. +.Pp +In compatibility (non-jobs) mode, each command is run in a separate process. +If the command contains any shell meta characters +.Pq Ql #=|^(){};&<>*?[]:$`\e\en +it will be passed to the shell, otherwise +.Nm +will attempt direct execution. +.Pp +Since +.Nm +will +.Xr chdir 2 +to +.Ql Va .OBJDIR +before executing any targets, each child process +starts with that as its current working directory. +.Pp +Makefiles should be written so that the mode of +.Nm +operation does not change their behavior. +For example, any command which needs to use +.Dq cd +or +.Dq chdir , +without side-effect should be put in parenthesis: +.Bd -literal -offset indent + +avoid-chdir-side-effects: + @echo Building $@ in `pwd` + @(cd ${.CURDIR} && ${.MAKE} $@) + @echo Back in `pwd` + +ensure-one-shell-regardless-of-mode: + @echo Building $@ in `pwd`; \\ + (cd ${.CURDIR} && ${.MAKE} $@); \\ + echo Back in `pwd` +.Ed +.Sh VARIABLE ASSIGNMENTS +Variables in make are much like variables in the shell, and, by tradition, +consist of all upper-case letters. +.Ss Variable assignment modifiers +The five operators that can be used to assign values to variables are as +follows: +.Bl -tag -width Ds +.It Ic \&= +Assign the value to the variable. +Any previous value is overridden. +.It Ic \&+= +Append the value to the current value of the variable. +.It Ic \&?= +Assign the value to the variable if it is not already defined. +.It Ic \&:= +Assign with expansion, i.e. expand the value before assigning it +to the variable. +Normally, expansion is not done until the variable is referenced. +.Em NOTE : +References to undefined variables are +.Em not +expanded. +This can cause problems when variable modifiers are used. +.It Ic \&!= +Expand the value and pass it to the shell for execution and assign +the result to the variable. +Any newlines in the result are replaced with spaces. +.El +.Pp +Any white-space before the assigned +.Ar value +is removed; if the value is being appended, a single space is inserted +between the previous contents of the variable and the appended value. +.Pp +Variables are expanded by surrounding the variable name with either +curly braces +.Pq Ql {} +or parentheses +.Pq Ql () +and preceding it with +a dollar sign +.Pq Ql \&$ . +If the variable name contains only a single letter, the surrounding +braces or parentheses are not required. +This shorter form is not recommended. +.Pp +If the variable name contains a dollar, then the name itself is expanded first. +This allows almost arbitrary variable names, however names containing dollar, +braces, parenthesis, or whitespace are really best avoided! +.Pp +If the result of expanding a variable contains a dollar sign +.Pq Ql \&$ +the string is expanded again. +.Pp +Variable substitution occurs at three distinct times, depending on where +the variable is being used. +.Bl -enum +.It +Variables in dependency lines are expanded as the line is read. +.It +Variables in shell commands are expanded when the shell command is +executed. +.It +.Dq .for +loop index variables are expanded on each loop iteration. +Note that other variables are not expanded inside loops so +the following example code: +.Bd -literal -offset indent + +.Dv .for i in 1 2 3 +a+= ${i} +j= ${i} +b+= ${j} +.Dv .endfor + +all: + @echo ${a} + @echo ${b} + +.Ed +will print: +.Bd -literal -offset indent +1 2 3 +3 3 3 + +.Ed +Because while ${a} contains +.Dq 1 2 3 +after the loop is executed, ${b} +contains +.Dq ${j} ${j} ${j} +which expands to +.Dq 3 3 3 +since after the loop completes ${j} contains +.Dq 3 . +.El +.Ss Variable classes +The four different classes of variables (in order of increasing precedence) +are: +.Bl -tag -width Ds +.It Environment variables +Variables defined as part of +.Nm Ns 's +environment. +.It Global variables +Variables defined in the makefile or in included makefiles. +.It Command line variables +Variables defined as part of the command line. +.It Local variables +Variables that are defined specific to a certain target. +The seven local variables are as follows: +.Bl -tag -width ".ARCHIVE" +.It Va .ALLSRC +The list of all sources for this target; also known as +.Ql Va \&\*[Gt] . +.It Va .ARCHIVE +The name of the archive file. +.It Va .IMPSRC +In suffix-transformation rules, the name/path of the source from which the +target is to be transformed (the +.Dq implied +source); also known as +.Ql Va \&\*[Lt] . +It is not defined in explicit rules. +.It Va .MEMBER +The name of the archive member. +.It Va .OODATE +The list of sources for this target that were deemed out-of-date; also +known as +.Ql Va \&? . +.It Va .PREFIX +The file prefix of the target, containing only the file portion, no suffix +or preceding directory components; also known as +.Ql Va * . +.It Va .TARGET +The name of the target; also known as +.Ql Va @ . +.El +.Pp +The shorter forms +.Ql Va @ , +.Ql Va \&? , +.Ql Va \&\*[Lt] , +.Ql Va \&\*[Gt] , +and +.Ql Va * +are permitted for backward +compatibility with historical makefiles and are not recommended. +The six variables +.Ql Va "@F" , +.Ql Va "@D" , +.Ql Va "\*[Lt]F" , +.Ql Va "\*[Lt]D" , +.Ql Va "*F" , +and +.Ql Va "*D" +are permitted for compatibility with +.At V +makefiles and are not recommended. +.Pp +Four of the local variables may be used in sources on dependency lines +because they expand to the proper value for each target on the line. +These variables are +.Ql Va .TARGET , +.Ql Va .PREFIX , +.Ql Va .ARCHIVE , +and +.Ql Va .MEMBER . +.El +.Ss Additional built-in variables +In addition, +.Nm +sets or knows about the following variables: +.Bl -tag -width .MAKEOVERRIDES +.It Va \&$ +A single dollar sign +.Ql \&$ , +i.e. +.Ql \&$$ +expands to a single dollar +sign. +.It Va .ALLTARGETS +The list of all targets encountered in the Makefile. +If evaluated during +Makefile parsing, lists only those targets encountered thus far. +.It Va .CURDIR +A path to the directory where +.Nm +was executed. +Refer to the description of +.Ql Ev PWD +for more details. +.It Ev MAKE +The name that +.Nm +was executed with +.Pq Va argv[0] . +For compatibility +.Nm +also sets +.Va .MAKE +with the same value. +The preferred variable to use is the environment variable +.Ev MAKE +because it is more compatible with other versions of +.Nm +and cannot be confused with the special target with the same name. +.It Va .MAKE.DEPENDFILE +Names the makefile (default +.Ql Pa .depend ) +from which generated dependencies are read. +.It Va .MAKE.EXPAND_VARIABLES +A boolean that controls the default behavior of the +.Fl V +option. +.It Va .MAKE.EXPORTED +The list of variables exported by +.Nm . +.It Va .MAKE.JOBS +The argument to the +.Fl j +option. +.It Va .MAKE.JOB.PREFIX +If +.Nm +is run with +.Ar j +then output for each target is prefixed with a token +.Ql --- target --- +the first part of which can be controlled via +.Va .MAKE.JOB.PREFIX . +.br +For example: +.Li .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}] +would produce tokens like +.Ql ---make[1234] target --- +making it easier to track the degree of parallelism being achieved. +.It Ev MAKEFLAGS +The environment variable +.Ql Ev MAKEFLAGS +may contain anything that +may be specified on +.Nm Ns 's +command line. +Anything specified on +.Nm Ns 's +command line is appended to the +.Ql Ev MAKEFLAGS +variable which is then +entered into the environment for all programs which +.Nm +executes. +.It Va .MAKE.LEVEL

The syntax is slightly different in that a single '.' is +used instead of the hash mark, i.e. ".include <bsd.prog.mk>". + +One difference that will save you lots of debugging time is that inclusion +of the file is normally done at the *end* of the Makefile. The reason for +this is because .mk files often modify variables and behavior based on the +values of variables set in the Makefile. To make this work, remember that +the FIRST target found is the target that is used, i.e. if the Makefile has: + + a: + echo a + a: + echo a number two + +the command "make a" will echo "a". To make things confusing, the SECOND +variable assignment is the overriding one, i.e. if the Makefile has: + + a= foo + a= bar + + b: + echo ${a} + +the command "make b" will echo "bar". This is for compatibility with the +way the V7 make behaved. + +It's fairly difficult to make the BSD .mk files work when you're building +multiple programs in a single directory. It's a lot easier split up the +programs than to deal with the problem. Most of the agony comes from making +the "obj" directory stuff work right, not because we switch to a new version +of make. So, don't get mad at us, figure out a better way to handle multiple +architectures so we can quit using the symbolic link stuff. (Imake doesn't +count.) + +The file .depend in the source directory is expected to contain dependencies +for the source files. This file is read automatically by make after reading +the Makefile. + +The variable DESTDIR works as before. It's not set anywhere but will change +the tree where the file gets installed. + +The profiled libraries are no longer built in a different directory than +the regular libraries. A new suffix, ".po", is used to denote a profiled +object. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= + +The include file <sys.mk> has the default rules for all makes, in the BSD +environment or otherwise. You probably don't want to touch this file. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= + +The include file <bsd.man.mk> handles installing manual pages and their +links. + +It has a single target: + + maninstall: + Install the manual pages and their links. + +It sets/uses the following variables: + +MANDIR Base path for manual installation. + +MANGRP Manual group. + +MANOWN Manual owner. + +MANMODE Manual mode. + +MANSUBDIR Subdirectory under the manual page section, i.e. "/vax" + or "/tahoe" for machine specific manual pages. + +MAN The manual pages to be installed (use a .1 - .9 suffix). + +MLINKS List of manual page links (using a .1 - .9 suffix). The + linked-to file must come first, the linked file second, + and there may be multiple pairs. The files are soft-linked. + +The include file <bsd.man.mk> includes a file named "../Makefile.inc" if +it exists. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= + +The include file <bsd.own.mk> contains source tree configuration parameters, +such as the owners, groups, etc. for both manual pages and binaries, and +a few global "feature configuration" parameters. + +It has no targets. + +To get system-specific configuration parameters, bsd.own.mk will try to +include the file specified by the "MAKECONF" variable. If MAKECONF is not +set, or no such file exists, the system make configuration file, /etc/mk.conf +is included. These files may define any of the variables described below. + +bsd.own.mk sets the following variables, if they are not already defined +(defaults are in brackets): + +BSDSRCDIR The real path to the system sources, so that 'make obj' + will work correctly. [/usr/src] + +BSDOBJDIR The real path to the system 'obj' tree, so that 'make obj' + will work correctly. [/usr/obj] + +BINGRP Binary group. [bin] + +BINOWN Binary owner.

[bin] + +NLSOWN National Language Support files owner. [bin] + +NLSMODE National Language Support files mode. [${NONBINMODE}] + +STRIP The flag passed to the install program to cause the binary + to be stripped. This is to be used when building your + own install script so that the entire system can be made + stripped/not-stripped using a single knob. [-s] + +COPY The flag passed to the install program to cause the binary + to be copied rather than moved. This is to be used when + building our own install script so that the entire system + can either be installed with copies, or with moves using + a single knob. [-c] + +Additionally, the following variables may be set by bsd.own.mk or in a +make configuration file to modify the behaviour of the system build +process (default values are in brackets along with comments, if set by +bsd.own.mk): + +EXPORTABLE_SYSTEM + Do not build /usr/src/domestic, even if it is present. + +SKEY Compile in support for S/key authentication. [yes, set + unconditionally] + +KERBEROS Compile in support for Kerberos 4 authentication. + +KERBEROS5 Compile in support for Kerberos 5 authentication. + +MANZ Compress manual pages at installation time. + +SYS_INCLUDE Copy or symlink kernel include files into /usr/include. + Possible values are "symlinks" or "copies" (which is + the same as the variable being unset). + +NOPROFILE Do not build profiled versions of system libraries + +NOPIC Do not build PIC versions of system libraries, and + do not build shared libraries. [set if ${MACHINE_ARCH} + is "mips", "vax", "alpha" or "arm32", unset otherwise.] + +NOLINT Do not build lint libraries. [set, set unconditionally] + +bsd.own.mk is generally useful when building your own Makefiles so that +they use the same default owners etc. as the rest of the tree. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= + +The include file <bsd.prog.mk> handles building programs from one or +more source files, along with their manual pages. It has a limited number +of suffixes, consistent with the current needs of the BSD tree. + +It has eight targets: + + all: + build the program and its manual page + clean: + remove the program, any object files and the files a.out, + Errs, errs, mklog, and core. + cleandir: + remove all of the files removed by the target clean, as + well as .depend, tags, and any manual pages. + depend: + make the dependencies for the source files, and store + them in the file .depend. + includes: + install any header files. + install: + install the program and its manual pages; if the Makefile + does not itself define the target install, the targets + beforeinstall and afterinstall may also be used to cause + actions immediately before and after the install target + is executed. + lint: + run lint on the source files + tags: + create a tags file for the source files. + +It sets/uses the following variables: + +BINGRP Binary group. + +BINOWN Binary owner. + +BINMODE Binary mode. + +CLEANFILES Additional files to remove for the clean and cleandir targets. + +COPTS Additional flags to the compiler when creating C objects. + +HIDEGAME If HIDEGAME is defined, the binary is installed in + /usr/games/hide, and a symbolic link is created to + /usr/games/dm. + +LDADD Additional loader objects. Usually used for libraries. + For example, to load with the compatibility and utility + libraries, use: + + LDADD+=-lutil -lcompat + +LDFLAGS Additional loader flags. + +LINKS The list of binary links; should be full pathnames, the + linked-to file coming first, followed by the linked + file. The files are hard-linked. For example, to link + /bin/test and /bin/[, use: + + LINKS= ${DESTDIR}/bin/test ${DESTDIR}/bin/[ + +MAN Manual pages (should end in .1 - .9). If no MAN variable is + defined, "MAN=${PROG}.1" is assumed. + +PROG The name of the program to build. If not supplied, nothing + is built. + +SRCS List of source files to build the program. If PROG is not + defined, it's assumed to be ${PROG}.c. + +DPADD Additional dependencies for the program. Usually used for + libraries. For example, to depend on the compatibility and + utility libraries use: + + DPADD+=${LIBCOMPAT} ${LIBUTIL} + + The following libraries are predefined for DPADD: + + LIBC /lib/libc.a + LIBCOMPAT /usr/lib/libcompat.a + LIBCRYPT /usr/lib/libcrypt.a + LIBCURSES /usr/lib/libcurses.a + LIBDBM /usr/lib/libdbm.a + LIBDES /usr/lib/libdes.a + LIBL /usr/lib/libl.a + LIBKDB /usr/lib/libkdb.a + LIBKRB /usr/lib/libkrb.a + LIBKVM /usr/lib/libkvm.a + LIBM /usr/lib/libm.a + LIBMP /usr/lib/libmp.a + LIBPC /usr/lib/libpc.a + LIBPLOT /usr/lib/libplot.a + LIBRPC /usr/lib/sunrpc.a + LIBTERM /usr/lib/libterm.a + LIBUTIL /usr/lib/libutil.a + +SHAREDSTRINGS If defined, a new .c.o rule is used that results in shared + strings, using xstr(1). Note that this will not work with + parallel makes. + +STRIP The flag passed to the install program to cause the binary + to be stripped. + +SUBDIR A list of subdirectories that should be built as well. + Each of the targets will execute the same target in the + subdirectories. + +The include file <bsd.prog.mk> includes the file named "../Makefile.inc" +if it exists, as well as the include file <bsd.man.mk>. + +Some simple examples: + +To build foo from foo.c with a manual page foo.1, use: + + PROG= foo + + .include <bsd.prog.mk> + +To build foo from foo.c with a manual page foo.2, add the line: + + MAN= foo.2 + +If foo does not have a manual page at all, add the line: + + NOMAN= noman + +If foo has multiple source files, add the line: + + SRCS= a.c b.c c.c d.c + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= + +The include file <bsd.subdir.mk> contains the default targets for building +subdirectories. It has the same eight targets as <bsd.prog.mk>: all, +clean, cleandir, depend, includes, install, lint, and tags. For all of +the directories listed in the variable SUBDIRS, the specified directory +will be visited and the target made. There is also a default target which +allows the command "make subdir" where subdir is any directory listed in +the variable SUBDIRS. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= + +The include file <bsd.sys.mk> is used by <bsd.prog.mk> and +<bsd.lib.mk>. It contains overrides that are used when building +the NetBSD source tree.

A directory produces one +component, which is generally either a library or a program. +Library makefiles include ``lib.mk`` and programs include ``prog.mk`` +and they *do the right thing*. + +A simple library makefile might look like:: + + LIB = sig + + SRCS = \ + sigaction.c \ + sigcompat.c \ + sighdl.c + + .include <lib.mk> + +a simple program makefile:: + + PROG = cat + + SRCS = cat.c + + .include <prog.mk> + +in such cases even the ``SRCS`` line is unnecessary as ``prog.mk`` +will default it to ``${PROG}.c``. + +It is the sensible use of defaults and the plethora of macro modifiers +provided by bmake_ that allow simple makefiles such as the above +*just work* on many different systems. + + +mk-files +======== + +This section provides a brief description of some of the ``*.mk`` +files. + +sys.mk +------ + +When bmake starts, it looks for ``sys.mk`` and reads it before doing +anything else. Thus, this is the place to setup the environment for +everyone else. + +In this distribution, sys.mk avoids doing anything platform dependent. +It is quite short, and includes a number of other files (which may or +may not exists) + +sys.env.mk + If it exists, is expected to do things like conditioning the + environment. Since it will only be included by the initial + instance of bmake, it should ``.export`` anything that + sub-makes might need. + +examples/sys.clean-env.mk + An example of how to clean the environment. + See the file for all the details:: + + .if ${MAKE_VERSION} >= 20100606 && ${.MAKE.LEVEL} == 0 + # we save any env var that starts with these + MAKE_SAVE_ENV_PREFIX += SB MK MAKE MACHINE NEED_ CCACHE DISTCC USE_ SSH + MAKE_SAVE_ENV_VARS += \ + PATH HOME USER LOGNAME \ + SRCTOP OBJTOP OBJROOT \ + ${_env_vars} + + _env_vars != env | egrep '^(${MAKE_SAVE_ENV_PREFIX:ts|})' | sed 's,=.*,,'; echo + _export_list = + .for v in ${MAKE_SAVE_ENV_VARS:O:u} + .if !empty($v) + _export_list += $v + $v := ${$v} + .endif + .endfor + # now clobber the environment + .unexport-env + + # list of vars that we handle specially below + _tricky_env_vars = MAKEOBJDIR + # export our selection - sans tricky ones + .export ${_export_list:${_tricky_env_vars:${M_ListToSkip}}} + + # this next bit may need tweaking + .if defined(MAKEOBJDIR) + srctop := ${SRCTOP:U${SB_SRC:U${SB}/src}} + objroot := ${OBJROOT:U${SB_OBJROOT:U${SB}/${SB_OBJPREFIX}}} + # we'll take care of MACHINE below + objtop := ${OBJTOP:U${objroot}${MACHINE}} + .if !empty(objtop) + # we would normally want something like (/bin/sh): + # MAKEOBJDIR="\${.CURDIR:S,${SRCTOP},${OBJROOT}\${MACHINE},}" + # the $$ below is how we achieve the same result here. + # since everything saved from the environment above + # has run through := we need to compensate for ${MACHINE} + MAKEOBJDIR = $${.CURDIR:S,${srctop},${objtop:S,${MACHINE},\${MACHINE},},} + + # export these as-is, and do not track... + .export-env ${_tricky_env_vars} + # now evaluate for ourselves + .for v in ${_tricky_env_vars} + $v := ${$v} + .endfor + + .endif + .endif + .endif + + +host-target.mk + Is used to set macros like ``HOST_TARGET``, ``HOST_OS`` and + ``host_os`` which are used to find the next step. + +sys/\*.mk + Platform specific additions, such as ``Darwin.mk`` or ``SunOS.mk`` + set things like ``HOST_LIBEXT = .dylib`` for Darwin or + ``SHLIB_FULLVERSION = ${SHLIB_MAJOR}`` for SunOS 5. + If there is no OS specific file, ``sys/Generic.mk`` is used. + +local.sys.mk + Any ``local.*.mk`` file is not part of the distribution. + This provides a hook for sites to do extra setup without + having to edit the distributed files. + + +The above arrangement makes it easy for the mk files to be part of a +src tree on an NFS volume and to allow building on multiple platforms. + +lib.mk +------ + +This file is used to build a number of different libraries from the +same SRCS. + +lib${LIB}.a + An archive lib of ``.o`` files, this is the default + +lib${LIB}_p.a + A profiled lib of ``.po`` files. + Still an archive lib, but all the objects are built with + profiling in mind - hence the different extension. + It is skipped if ``MKPROFILE`` is "no". + +lib${LIB}_pic.a + An archive of ``.so`` objects compiled for relocation. + On NetBSD this is the input to ``lib${LIB}.${LD_so}``, it is + skipped if ``MKPICLIB`` is "no". + +lib${LIB}.${LD_so} + A shared library. The value of ``LD_so`` is very platform + specific. For example:: + + # SunOS 5 and most other ELF systems + libsslfd.so.1 + + # Darwin + libsslfd.1.dylib + + This library will only be built if ``SHLIB_MAJOR`` has + a value, and ``MKPIC`` is not set to "no". + +There is a lot of platform specific tweaking in ``lib.mk``, largely the +result of the original distributions trying to avoid interfering with +the system's ``sys.mk``. + +libnames.mk +----------- + +This is included by both ``prog.mk`` and ``lib.mk`` and tries to +include ``*.libnames.mk`` of which: + +local.libnames.mk + does not exist unless you create it. It is a handy way for you + to customize without touching the distributed files. + For example, on a test machine I needed to build openssl but + not install it, so put the following in ``local.libnames.mk``:: + + .if ${host_os} == "sunos" + LIBCRYPTO = ${OBJTOP}/openssl/lib/crypto/libcrypto${DLIBEXT} + LIBSSL = ${OBJTOP}/openssl/lib/ssl/libssl${DLIBEXT} + INCLUDES_libcrypto = -I${OBJ_libcrypto} + .endif + + The makefile created an openssl dir in ``${OBJ_libcrypto}`` to + gather all the headers. dpadd.mk_ did the rest. + +sjg.libnames.mk + not part of the mk-files distribution. + +host.libnames.mk + contains logic to find any libs named in ``HOST_LIBS`` in + ``HOST_LIBDIRS``. + +Each file above gets an opportunity to define things like:: + + LIBSSLFD ?= ${OBJTOP}/ssl/lib/sslfd/libsslfd${DLIBEXT} + INCLUDES_libsslfd = -I${SRC_libsslfd}/h -I${OBJ_libslfd} + +these are used by dpadd.mk_ and will be explained below. + +dpadd.mk +-------- + +This file looks like line noise, and is best considered read-only. +However it provides some very useful functionality, which simplifies the build. + +Makefiles can use the LIB* macros defined via libnames.mk_ or anywhere +else in various ways:: + + # indicate that we need to include headers from LIBCRYPTO + # this would result in ${INCLUDES_libcrypto} being added to CFLAGS. + SRC_LIBS += ${LIBCRYPTO} + + # indicate that libsslfd must be built already. + # it also has the same effect as SRC_LIBS + DPADD += ${LIBSSLFD} + + # indicate that not only must libsslfd be built, + # but that we need to link with it. + # this is almost exactly equivalent to + # DPADD += ${LIBSSLFD} + # LDADD += -L${LIBSSLFD:H} -lsslfd + # and mostly serves to ensure that DPADD and LDADD are in sync. + DPLIBS += ${LIBSSLFD} + +Any library (referenced by its full path) in any of the above, is +added to ``DPMAGIC_LIBS`` with the following results, for each lib *foo*. + +SRC_libfoo + Is set to indicate where the src for libfoo is. + By default it is derived from ``LIBFOO`` by replacing + ``${OBJTOP}`` with ``${SRCTOP}``. + +OBJ_libfoo + Not very exciting, is just the dir where libfoo lives. + +INCLUDES_libfoo + What to add to ``CFLAGS`` to find the public headers. + The default varies. If ``${SRC_libfoo}/h`` exists, it is assumed + to be the home of all public headers and thus the default is + ``-I${SRC_libfoo}/h`` + + Otherwise we make no assumptions and the default is + ``-I${SRC_libfoo} -I${OBJ_libfoo}`` + +LDADD_libfoo + This only applies to libs reference via ``DPLIBS``. + The default is ``-lfoo``, ``LDADD_*`` provides a hook to + instantiate other linker flags at the appropriate point + without losing the benfits of ``DPLIBS``. + +prog.mk +------- + +Compiles the specified SRCS and links them and the nominated libraries +into a program. Prog makefiles usually need to list the libraries +that need to be linked. We prefer use of ``DPLIBS`` but the more +traditional ``DPADD`` and ``LDADD`` work just as well. +That is:: + + DPLIBS += ${LIBCRYPTO} + +is equivalent to:: + + DPADD += ${LIBCRYPTO} + LDADD += -lcrypto + +obj.mk +------ + +One of the cool aspects of BSD make, is its support for separating +object files from the src tree. This is also the source of much +confusion to some. + +Traditionally one had to do a separate ``make obj`` pass through the +tree. If ``MKOBJDIRS`` is "auto", we include auto.obj.mk_. + +auto.obj.mk +----------- + +This leverages the ``.OBJDIR`` target introduced some years ago to +NetBSD make, to automatically create the desired object dir. + +subdir.mk +--------- + +This is the traditional means of walking the tree. A makefile sets +``SUBDIR`` to the list of sub-dirs to visit. + +If ``SUBDIR_MUST_EXIST`` is set, missing directories cause an error, +otherwise a warning is issued. If you don't even want the warning, +set ``MISSING_DIR=continue``. + +Traditionally, ``subdir.mk`` prints clue as it visits each subdir:: + + ===> ssl + ===> ssl/lib + ===> ssl/lib/sslfd + +you can suppress that - or enhance it by setting ``ECHO_DIR``:: + + # suppress subdir noise + ECHO_DIR=: + # print time stamps + ECHO_DIR=echo @ `date "+%s [%Y-%m-%d %T] "` + +links.mk +-------- + +Provides rules for processing lists of ``LINKS`` and ``SYMLINKS``. +Each is expected to be a list of ``link`` and ``target`` pairs +(``link`` -> ``target``). + +The logic is generally in a ``_*_SCRIPT`` which is referenced in a +``_*_USE`` (``.USE``) target. + +The ``_BUILD_*`` forms are identical, but do not use ``${DESTDIR}`` +and so are useful for creating symlinks during the build phase. +For example:: + + SYMLINKS += ${.CURDIR}/${MACHINE_ARCH}/include machine + header_links: _BUILD_SYMLINKS_USE + + md.o: header_links + +would create a symlink called ``machine`` in ``${.OBJDIR}`` pointing to +``${.CURDIR}/${MACHINE_ARCH}/include`` before compiling ``md.o`` + + +autoconf.mk +----------- + +Deals with running (or generating) GNU autoconf ``configure`` scripts. + +dep.mk +------ + +Deals with collecting dependencies. Another useful feature of BSD +make is the separation of this sort of information into a ``.depend`` +file. ``MKDEP`` needs to point to a suitable tool (like mkdeps.sh_) + +If ``USE_AUTODEP_MK`` is "yes" includes autodep.mk_ + +autodep.mk +---------- + +Leverages the ``-MD`` feature of recent GCC to collect dependency +information as a side effect of compilation. With this GCC puts +dependency info into a ``.d`` file. + +Unfortunately GCC bases the name of the ``.d`` file on the name of the +input rather than the output file, which causes problems when the same +source is compiled different ways. The latest GCC supports ``-MF`` to +name the ``.d`` file and ``-MT`` to control the name to put as the +dependent. + +Recent bmake allows dependencies for the ``.END`` target (run at the +end if everything was successful), and ``autodep.mk`` uses this to +post process the ``.d`` files into ``.depend``. + +auto.dep.mk +----------- + +A much simpler implementation than autodep.mk_ it uses +``-MF ${.TARGET:T}.d`` +to avoid possible conflicts during parallel builds. +This precludes the use of suffix rules to drive ``make depend``, so +dep.mk_ handles that if specifically requested. + +own.mk +------ + +Normally included by ``init.mk`` (included by ``lib.mk`` and +``prog.mk`` etc), sets macros for default ownership etc. + +It includes ``${MAKECONF}`` if it is defined and exists. + +man.mk +------ + +Deals with man pages. + +warnings.mk +----------- + +This provides a means of fine grained control over warnings on a per +``${MACHINE}`` or even file basis. + +A makefile sets ``WARNINGS_SET`` to name a list of warnings +and individual ``W_*`` macros can be used to tweak them. +For example:: + + WARNINGS_SET = HIGH + W_unused_sparc = -Wno-unused + +would add all the warnings in ``${HIGH_WARNINGS}`` to CFLAGS, but +on sparc, ``-Wno-unused`` would replace ``-Wunused``. + +You should never need to edit ``warnings.mk``, it will include +``warnings-sets.mk`` if it exists and you use that to make any local +customizations. + +Meta mode +========= + +The 20110505 and later versions of ``mk-files`` include a number of +makefile contributed by Juniper Networks, Inc. +These allow the latest version of bmake_ to run in `meta mode`_. + +.. _`meta mode`: bmake-meta-mode.htm + +Install +======= + +You can use the content of mk.tar.gz_ without installing at all. + +The script ``install-mk`` takes care of copying ``*.mk`` into a +destination directory, and unless told not to, create ``bsd.*.mk`` links +for ``lib.mk`` etc. + +If you just want to create the ``bsd.*.mk`` links in the directory +where you unpacked the tar file, you can:: + + ./mk/install-mk ./mk + +------ + +.. _bmake: bmake.htm +.. _NetBSD: http://www.netbsd.org/ +.. _mkdeps.sh: http://www.crufty.net/ftp/pub/sjg/mkdeps.sh +.. _mk.tar.gz: http://www.crufty.net/ftp/pub/sjg/mk.tar.gz + +:Author: sjg@crufty.net +:Revision: $Id: mk-files.txt,v 1.15 2011/06/08 07:06:18 sjg Exp $ +:Copyright: Crufty.NET diff --git a/20130123/mk/nls.mk b/20130123/mk/nls.mk new file mode 100644 index 0000000..e302c8d --- /dev/null +++ b/20130123/mk/nls.mk @@ -0,0 +1,48 @@ +# $NetBSD: bsd.nls.mk,v 1.3 1996/10/18 02:34:45 thorpej Exp $ + +.if !target(.MAIN) +.if exists(${.CURDIR}/../Makefile.inc) +.include "${.CURDIR}/../Makefile.inc" +.endif + +.MAIN: all +.endif + +.SUFFIXES: .cat .msg + +.msg.cat: + @rm -f ${.TARGET} + gencat ${.TARGET} ${.IMPSRC} + +.if defined(NLS) && !empty(NLS) +NLSALL= ${NLS:.msg=.cat} +.NOPATH: ${NLSALL} +.endif + +.if !defined(NLSNAME) +.if defined(PROG) +NLSNAME=${PROG} +.else +NLSNAME=lib${LIB} +.endif +.endif + +nlsinstall: +.if defined(NLSALL) + @for msg in ${NLSALL}; do \ + NLSLANG=`basename $$msg .cat`; \ + dir=${DESTDIR}${NLSDIR}/$${NLSLANG}; \ + ${INSTALL} -d $$dir; \ + ${INSTALL} ${COPY} -o ${NLSOWN} -g ${NLSGRP} -m ${NLSMODE} $$msg $$dir/${NLSNAME}.cat; \ + done +.endif + +.if defined(NLSALL) +all: ${NLSALL} + +install: nlsinstall + +cleandir: cleannls +cleannls: + rm -f ${NLSALL} +.endif diff --git a/20130123/mk/obj.mk b/20130123/mk/obj.mk new file mode 100644 index 0000000..b936379 --- /dev/null +++ b/20130123/mk/obj.mk @@ -0,0 +1,113 @@ +# $Id: obj.mk,v 1.15 2012/11/11 22:37:02 sjg Exp $ +# +# @(#) Copyright (c) 1999-2010, Simon J.
