Gerraty <sjg@zen.quick.com.au> - - * job.c (JobFinish): Fix an earlier merge bug that resulted in - leaking descriptors when using -jN. - - * job.c (JobPrintCommand): See if "curdir" exists before - attempting to chdir().

Gerraty <sjg@zen.quick.com.au> - - * job.c (Job_CatchChildren): don't call Job_CatchOutput() here, - its the wrong "fix". - -Sat Jun 9 00:11:24 2001 Simon J. 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> - - * make-conf.h (USE_IOVEC): make it conditional on HAVE_SYS_UIO_H - - * Merged with NetBSD make - make -dx can now be used to run commands via sh -x - better error messages on exec failures. - -Thu May 31 01:44:54 2001 Simon J. Gerraty <sjg@zen.quick.com.au> - - * Makefile.in (main.o): depends on ${SRCS} ${MAKEFILE} so that - MAKE_VERSION gets updated. Also don't use ?= for MAKE_VERSION, - MACHINE etc otherwise they propagate from the previous bmake. - - * configure.in (machine): allow --with-machine=generic to make - configure use machine.sh to set MACHINE. - - * job.c (JobInterrupt): convert to using WAIT_T and friends. - - * Makefile.in: mention in bmake.1 that we use autoconf. - - * make.1: mention MAKE_PRINT_VAR_ON_ERROR. - -Wed May 30 23:17:18 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. Gerraty <sjg@zen.quick.com.au> - - * Merged with NetBSD make - - * var.c: fixed a bug in the handling of the modifier :P - if the node as found but the path was null, we segfault trying to - duplicate it. - -Mon Mar 5 16:20:33 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. So you round out the makefile with these lines: -.DS -main.o : main.c - cc -c main.c -parse.o : parse.c - cc -c parse.c -output.o : output.c - cc -c output.c -.DE -.LP -The makefile is now complete and will, in fact, create the program you -want it to without unnecessary compilations or excessive typing on -your part. There are two things wrong with it, however (aside from it -being altogether too long, something I'll address in chapter 3): -.IP 1) -The string -.CW "main.o parse.o output.o" '' `` -is repeated twice, necessitating two changes when you add postfix -(you were planning on that, weren't you?). This is in direct violation -of de Boor's First Rule of writing makefiles: -.QP -.I -Anything that needs to be written more than once -should be placed in a variable. -.IP "\&" -I cannot emphasize this enough as being very important to the -maintenance of a makefile and its program. -.IP 2) -There is no way to alter the way compilations are performed short of -editing the makefile and making the change in all places. This is evil -and violates de Boor's Second Rule, which follows directly from the -first: -.QP -.I -Any flags or programs used inside a makefile should be placed in a variable so -they may be changed, temporarily or permanently, with the greatest ease. -.LP -The makefile should more properly read: -.DS -OBJS = main.o parse.o output.o -expr : $(OBJS) - $(CC) $(CFLAGS) -o $(.TARGET) $(.ALLSRC) -main.o : main.c - $(CC) $(CFLAGS) -c main.c -parse.o : parse.c - $(CC) $(CFLAGS) -c parse.c -output.o : output.c - $(CC) $(CFLAGS) -c output.c -$(OBJS) : defs.h -.DE -Alternatively, if you like the idea of dynamic sources mentioned in -section 2.3.1, -.Rm 0 2.3.1 -.Rd 4 -.Ix 0 ref "dynamic source" -.Ix 0 ref source dynamic -you could write it like this: -.DS -OBJS = main.o parse.o output.o -expr : $(OBJS) - $(CC) $(CFLAGS) -o $(.TARGET) $(.ALLSRC) -$(OBJS) : $(.PREFIX).c defs.h - $(CC) $(CFLAGS) -c $(.PREFIX).c -.DE -These two rules and examples lead to de Boor's First Corollary: -.QP -.I -Variables are your friends. -.LP -Once you've written the makefile comes the sometimes-difficult task of -.Ix 0 ref debugging -making sure the darn thing works. Your most helpful tool to make sure -the makefile is at least syntactically correct is the -.B \-n -.Ix 0 ref flags -n -flag, which allows you to see if PMake will choke on the makefile. The -second thing the -.B \-n -flag lets you do is see what PMake would do without it actually doing -it, thus you can make sure the right commands would be executed were -you to give PMake its head. -.LP -When you find your makefile isn't behaving as you hoped, the first -question that comes to mind (after ``What time is it, anyway?'') is -``Why not?'' 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. You -can then use the information printed for other targets to see where -you went wrong. The -.CW "-p 2" '' `` -flag makes PMake print out its internal state when it is done, -allowing you to see that you forgot to make that one chapter depend on -that file of macros you just got a new version of. The output from -.CW "-p 2" '' `` -is intended to resemble closely a real makefile, but with additional -information provided and with variables expanded in those commands -PMake actually printed or executed. -.LP -Something to be especially careful about is circular dependencies. -.Ix 0 def dependency circular -E.g. -.DS -a : b -b : c d -d : a -.DE -In this case, because of how PMake works, -.CW c -is the only thing PMake will examine, because -.CW d -and -.CW a -will effectively fall off the edge of the universe, making it -impossible to examine -.CW b -(or them, for that matter). -PMake will tell you (if run in its normal mode) all the targets -involved in any cycle it looked at (i.e. if you have two cycles in the -graph (naughty, naughty), but only try to make a target in one of -them, PMake will only tell you about that one. You'll have to try to -make the other to find the second cycle). When run as Make, it will -only print the first target in the cycle. -.xH 2 Invoking PMake -.LP -.Ix 0 ref flags -.Ix 0 ref arguments -.Ix 0 ref usage -PMake comes with a wide variety of flags to choose from. -They may appear in any order, interspersed with command-line variable -assignments and targets to create. -The flags are as follows: -.IP "\fB\-d\fP \fIwhat\fP" -.Ix 0 def flags -d -.Ix 0 ref debugging -This causes PMake to spew out debugging information that -may prove useful to you.

Most of what I describe will make -little sense to you, unless you've dealt with Make before. Just -remember where this table is and come back to it as you read on. -The characters and the information they produce are as follows: -.RS -.IP a -Archive searching and caching. -.IP c -Conditional evaluation. -.IP d -The searching and caching of directories. -.IP j -Various snippets of information related to the running of the multiple -shells.

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.

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.

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.

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. This is true if the given target was -specified on the command line, or as the source for a -.CW .MAIN -target (note that the sources for -.CW .MAIN -are only used if no targets were given on the command line). -.IP defined \n(pw -.Ix 0 def defined -.Ix 0 def conditional defined -.Ix 0 def if defined -The syntax is -.CW defined( \fIvariable\fP\c -.CW ) -and is true if -.I variable -is defined. Certain variables are defined in the system makefile that -identify the system on which PMake is being run. -.IP exists \n(pw -.Ix 0 def exists -.Ix 0 def conditional exists -.Ix 0 def if exists -The syntax is -.CW exists( \fIfile\fP\c -.CW ) -and is true if the file can be found on the global search path -(i.e. that defined by -.CW .PATH -targets, not by -.CW .PATH \fIsuffix\fP -targets). -.IP empty \n(pw -.Ix 0 def empty -.Ix 0 def conditional empty -.Ix 0 def if empty -This syntax is much like the others, except the string inside the -parentheses is of the same form as you would put between parentheses -when expanding a variable, complete with modifiers and everything. 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/20120831/README b/20120831/README deleted file mode 100644 index fb688a3..0000000 --- a/20120831/README +++ /dev/null @@ -1,47 +0,0 @@ - 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.

-.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 -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

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. -.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.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 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 ${.MAKE.LEVEL} == 0 -to protect things which should only be evaluated in the initial instance of -.Nm . -.It Va .MAKE.MAKEFILE_PREFERENCE -The ordered list of makefile names -(default -.Ql Pa makefile , -.Ql Pa Makefile ) -that -.Nm -will look for. -.It Va .MAKE.MAKEFILES -The list of makefiles read by -.Nm , -which is useful for tracking dependencies. -Each makefile is recorded only once, regardless of the number of times read. -.It Va .MAKE.MODE -Processed after reading all makefiles. -Can affect the mode that -.Nm -runs in. -It can contain a number of keywords: -.Bl -hang -width ignore-cmd -.It Pa compat -Like -.Fl B , -puts -.Nm -into "compat" mode. -.It Pa meta -Puts -.Nm -into "meta" mode, where meta files are created for each target -to capture the command run, the output generated and if -.Xr filemon 4 -is available, the system calls which are of interest to -.Nm . -The captured output can be very useful when diagnosing errors. -.It Pa curdirOk= Ar bf -Normally -.Nm -will not create .meta files in -.Ql Va .CURDIR . -This can be overridden by setting -.Va bf -to a value which represents True. -.It Pa env -For debugging, it can be useful to inlcude the environment -in the .meta file. -.It Pa verbose -If in "meta" mode, print a clue about the target being built. -This is useful if the build is otherwise running silently. -The message printed the value of: -.Va .MAKE.META.PREFIX . -.It Pa ignore-cmd -Some makefiles have commands which are simply not stable. -This keyword causes them to be ignored for -determining whether a target is out of date in "meta" mode. -See also -.Ic .NOMETA_CMP . -.It Pa silent= Ar bf -If -.Va bf -is True, when a .meta file is created, mark the target -.Ic .SILENT . -.El -.It Va .MAKE.META.BAILIWICK -In "meta" mode, provides a list of prefixes which -match the directories controlled by -.Nm . -If a file that was generated outside of -.Va .OBJDIR -but within said bailiwick is missing, -the current target is considered out-of-date. -.It Va .MAKE.META.CREATED -In "meta" mode, this variable contains a list of all the meta files -updated. -If not empty, it can be used to trigger processing of -.Va .MAKE.META.FILES . -.It Va .MAKE.META.FILES -In "meta" mode, this variable contains a list of all the meta files -used (updated or not). -This list can be used to process the meta files to extract dependency -information. -.It Va .MAKE.META.PREFIX -Defines the message printed for each meta file updated in "meta verbose" mode. -The default value is: -.Dl Building ${.TARGET:H:tA}/${.TARGET:T} -.It Va .MAKEOVERRIDES -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 -.Ql Ev MAKEFLAGS . -This behaviour can be disabled by assigning an empty value to -.Ql Va .MAKEOVERRIDES -within a makefile. -Extra variables can be exported from a makefile -by appending their names to -.Ql Va .MAKEOVERRIDES . -.Ql Ev MAKEFLAGS -is re-exported whenever -.Ql Va .MAKEOVERRIDES -is modified. -.It Va .MAKE.PID -The process-id of -.Nm . -.It Va .MAKE.PPID -The parent process-id of -.Nm . -.It Va MAKE_PRINT_VAR_ON_ERROR -When -.Nm -stops due to an error, it prints its name and the value of -.Ql Va .CURDIR -as well as the value of any variables named in -.Ql Va MAKE_PRINT_VAR_ON_ERROR . -.It Va .newline -This variable is simply assigned a newline character as its value. -This allows expansions using the -.Cm \&:@ -modifier to put a newline between -iterations of the loop rather than a space. -For example, the printing of -.Ql Va MAKE_PRINT_VAR_ON_ERROR -could be done as ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}. -.It Va .OBJDIR -A path to the directory where the targets are built. -Its value is determined by trying to -.Xr chdir 2 -to the following directories in order and using the first match: -.Bl -enum -.It -.Ev ${MAKEOBJDIRPREFIX}${.CURDIR} -.Pp -(Only if -.Ql Ev MAKEOBJDIRPREFIX -is set in the

If the file `_._d_e_p_e_n_d' exists, it is read (see - mkdep(1)). - - This manual page is intended as a reference document only. For a more - thorough description of bbmmaakkee and makefiles, please refer to _P_M_a_k_e _- _A - _T_u_t_o_r_i_a_l. - - bbmmaakkee will prepend the contents of the _M_A_K_E_F_L_A_G_S environment variable to - the command line arguments before parsing them. - - The options are as follows: - - --BB 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. - - --CC _d_i_r_e_c_t_o_r_y - Change to _d_i_r_e_c_t_o_r_y before reading the makefiles or doing any- - thing else. If multiple --CC options are specified, each is inter- - preted relative to the previous one: --CC _/ --CC _e_t_c is equivalent to - --CC _/_e_t_c. - - --DD _v_a_r_i_a_b_l_e - Define _v_a_r_i_a_b_l_e to be 1, in the global context. - - --dd _[_-_]_f_l_a_g_s - Turn on debugging, and specify which portions of bbmmaakkee are to - print debugging information. Unless the flags are preceded by - `-' they are added to the _M_A_K_E_F_L_A_G_S 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 _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 out- - put is line buffered. _F_l_a_g_s is one or more of the following: - - _A Print all possible debugging information; equivalent to - specifying all of the debugging flags. - - _a Print debugging information about archive searching and - caching. - - _C Print debugging information about current working direc- - tory. - - _c Print debugging information about conditional evaluation. - - _d Print debugging information about directory searching and - caching. - - _e Print debugging information about failed commands and - targets. - - _F[++]_f_i_l_e_n_a_m_e - 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 `F' - flag is `+', then the file will be opened in append mode; - otherwise the file will be overwritten. If the file name - is `stdout' or `stderr' then debugging output will be - written to the standard output or standard error output - file descriptors respectively (and the `+' option has no - effect). Otherwise, the output will be written to the - named file. If the file name ends `.%d' then the `%d' is - replaced by the pid. - - _f Print debugging information about loop evaluation. - - _g_1 Print the input graph before making anything. - - _g_2 Print the input graph after making everything, or before - exiting on error. - - _g_3 Print the input graph before exiting on error. - - _j Print debugging information about running multiple - shells. - - _l Print commands in Makefiles regardless of whether or not - they are prefixed by `@' or other "quiet" flags. Also - known as "loud" behavior. - - _M Print debugging information about "meta" mode decisions - about targets. - - _m Print debugging information about making targets, includ- - ing modification dates. - - _n Don't delete the temporary command scripts created when - running commands. These temporary scripts are created in - the directory referred to by the TMPDIR environment vari- - able, or in _/_t_m_p if TMPDIR is unset or set to the empty - string. The temporary scripts are created by mkstemp(3), - and have names of the form _m_a_k_e_X_X_X_X_X_X. _N_O_T_E: This can - create many files in TMPDIR or _/_t_m_p, so use with care. - - _p Print debugging information about makefile parsing. - - _s Print debugging information about suffix-transformation - rules. - - _t Print debugging information about target list mainte- - nance. - - _v Print debugging information about variable assignment. - - _x Run shell commands with --xx so the actual commands are - printed as they are executed. - - --ee Specify that environment variables override macro assignments - within makefiles. - - --ff _m_a_k_e_f_i_l_e - Specify a makefile to read instead of the default `_m_a_k_e_f_i_l_e'. If - _m_a_k_e_f_i_l_e is `--', standard input is read. 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. When com- - patibility mode is off, all commands associated with a target are - executed in a single shell invocation as opposed to the tradi- - tional 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. - - --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. Equivalent to - specifying `@@' before each command line in the makefile. - - --TT _t_r_a_c_e_f_i_l_e - When used with the --jj flag, append a trace record to _t_r_a_c_e_f_i_l_e - for each job started and completed. - - --tt 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. - - --VV _v_a_r_i_a_b_l_e - Print bbmmaakkee's idea of the value of _v_a_r_i_a_b_l_e, in the global con- - text. 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. - -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. If - evaluated during Makefile parsing, lists only those tar- - gets encountered thus far. - - _._C_U_R_D_I_R A path to the directory where bbmmaakkee was executed. Refer - to the description of `PWD' for more details. - - MAKE The name that bbmmaakkee was executed with (_a_r_g_v_[_0_]). For - compatibility bbmmaakkee also sets _._M_A_K_E with the same value. - The preferred variable to use is the environment variable - MAKE because it is more compatible with other versions of - bbmmaakkee and cannot be confused with the special target with - the same name. - - _._M_A_K_E_._D_E_P_E_N_D_F_I_L_E - Names the makefile (default `_._d_e_p_e_n_d') from which gener- - ated dependencies are read. - - _._M_A_K_E_._E_X_P_O_R_T_E_D The list of variables exported by bbmmaakkee. - - _._M_A_K_E_._J_O_B_S The argument to the --jj option. - - _._M_A_K_E_._J_O_B_._P_R_E_F_I_X - If bbmmaakkee is run with _j then output for each target is - prefixed with a token `--- target ---' the first part of - which can be controlled via _._M_A_K_E_._J_O_B_._P_R_E_F_I_X. - For example: - .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}] - would produce tokens like `---make[1234] target ---' mak- - ing it easier to track the degree of parallelism being - achieved. - - MAKEFLAGS The environment variable `MAKEFLAGS' may contain anything - that may be specified on bbmmaakkee's command line. Anything - specified on bbmmaakkee's command line is appended to the - `MAKEFLAGS' variable which is then entered into the envi- - ronment for all programs which bbmmaakkee executes. - - _._M_A_K_E_._L_E_V_E_L The recursion depth of bbmmaakkee. The initial instance of - bbmmaakkee will be 0, and an incremented value is put into the - environment to be seen by the next generation. This - allows tests like: .if ${.MAKE.LEVEL} == 0 to protect - things which should only be evaluated in the initial - instance of bbmmaakkee. - - _._M_A_K_E_._M_A_K_E_F_I_L_E___P_R_E_F_E_R_E_N_C_E - The ordered list of makefile names (default `_m_a_k_e_f_i_l_e', - `_M_a_k_e_f_i_l_e') that bbmmaakkee will look for. - - _._M_A_K_E_._M_A_K_E_F_I_L_E_S - The list of makefiles read by bbmmaakkee, which is useful for - tracking dependencies. Each makefile is recorded only - once, regardless of the number of times read. - - _._M_A_K_E_._M_O_D_E Processed after reading all makefiles. Can affect the - mode that bbmmaakkee runs in. It can contain a number of key- - words: - - _c_o_m_p_a_t Like --BB, puts bbmmaakkee into "compat" mode. - - _m_e_t_a Puts bbmmaakkee into "meta" mode, where meta files - are created for each target to capture the - command run, the output generated and if - filemon(4) is available, the system calls - which are of interest to bbmmaakkee. 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 can be overridden by set- - ting _b_f to a value which represents True. - - _e_n_v For debugging, it can be useful to inlcude - the environment in the .meta file. - - _v_e_r_b_o_s_e If in "meta" mode, print a clue about the - target being built. 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. This keyword causes them to be - ignored for determining whether a target is - out of date in "meta" mode. See also - ..NNOOMMEETTAA__CCMMPP. - - _s_i_l_e_n_t_= _b_f If _b_f is True, when a .meta file is created, - mark the target ..SSIILLEENNTT. - - _._M_A_K_E_._M_E_T_A_._B_A_I_L_I_W_I_C_K - In "meta" mode, provides a list of prefixes which match - the directories controlled by bbmmaakkee. If a file that was - generated outside of _._O_B_J_D_I_R but within said bailiwick is - missing, the current target is considered out-of-date. - - _._M_A_K_E_._M_E_T_A_._C_R_E_A_T_E_D - In "meta" mode, this variable contains a list of all the - meta files updated. If not empty, it can be used to - trigger processing of _._M_A_K_E_._M_E_T_A_._F_I_L_E_S. - - _._M_A_K_E_._M_E_T_A_._F_I_L_E_S - In "meta" mode, this variable contains a list of all the - meta files used (updated or not). This list can be used - to process the meta files to extract dependency informa- - tion. - - _._M_A_K_E_._M_E_T_A_._P_R_E_F_I_X - Defines the message printed for each meta file updated in - "meta verbose" mode. 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. Its - value is determined by trying to chdir(2) to the follow- - ing directories in order and using the first match: - - 1. ${MAKEOBJDIRPREFIX}${.CURDIR} - - (Only if `MAKEOBJDIRPREFIX' is set in the environ- - ment or on the command line.) - - 2. ${MAKEOBJDIR} - - (Only if `MAKEOBJDIR' is set in the environment or - on the command line.) - - 3. ${.CURDIR}_/_o_b_j_.${MACHINE} - - 4. ${.CURDIR}_/_o_b_j - - 5. _/_u_s_r_/_o_b_j_/${.CURDIR} - - 6. ${.CURDIR} - - Variable expansion is performed on the value before it's - used, so expressions such as - ${.CURDIR:S,^/usr/src,/var/obj,} - may be used. 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. The wildcard - characters may be escaped with a backslash (`\'). - - ::NN_p_a_t_t_e_r_n - This is identical to `::MM', but selects all words which do not match - _p_a_t_t_e_r_n. - - ::OO Order every word in variable alphabetically. 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. For example, - - LIST= uno due tre quattro - RANDOM_LIST= ${LIST:Ox} - STATIC_RANDOM_LIST:= ${LIST:Ox} - - all: - @echo "${RANDOM_LIST}" - @echo "${RANDOM_LIST}" - @echo "${STATIC_RANDOM_LIST}" - @echo "${STATIC_RANDOM_LIST}" - may produce output similar to: - - quattro due tre uno - tre due quattro uno - due uno quattro tre - due uno quattro tre - - ::QQ Quotes every shell meta-character in the variable, so that it can be - passed safely through recursive invocations of bbmmaakkee. - - ::RR Replaces each word in the variable with everything but its suffix. - - ::ggmmttiimmee - The value is a format string for strftime(3), using the current - gmtime(3). - - ::hhaasshh - Compute a 32bit hash of the value and encode it as hex digits. - - ::llooccaallttiimmee - The value is a format string for strftime(3), using the current - localtime(3). - - ::ttAA Attempt to convert variable to an absolute path using realpath(3), - if that fails, the value is unchanged. - - ::ttll Converts variable to lower-case letters. - - ::ttss_c - Words in the variable are normally separated by a space on expan- - sion. 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. It must - be the last modifier specified. 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. Unlike ..ffoorr loops expansion occurs at the time - of reference. Assign _t_e_m_p to each word in the variable and evaluate - _s_t_r_i_n_g. The ODE convention is that _t_e_m_p should start and end with a - period. For example. - ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@} - - However a single character varaiable is often more readable: - ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@} - - ::UU_n_e_w_v_a_l - If the variable is undefined _n_e_w_v_a_l is the value. If the variable - is defined, the existing value is returned. This is another ODE - make feature. It is handy for setting per-target CFLAGS for - instance: - ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}} - If a value is only required if the variable is undefined, use: - ${VAR:D:Unewval} - - ::DD_n_e_w_v_a_l - If the variable is defined _n_e_w_v_a_l is the value. - - ::LL The name of the variable is the value. - - ::PP The path of the node which has the same name as the variable is the - value. If no such node exists or its path is null, then the name of - the variable is used. In order for this modifier to work, the name - (node) must at least have appeared on the rhs of a dependency. - - ::!!_c_m_d!! - The output of running _c_m_d is the value. - - ::sshh If the variable is non-empty it is run as a command and the output - becomes the new value. - - ::::==_s_t_r - The variable is assigned the value _s_t_r after substitution. This - modifier and its variations are useful in obscure situations such as - wanting to set a variable when shell commands are being parsed. - These assignment modifiers always expand to nothing, so if appearing - in a rule line by themselves should be preceded with something to - keep bbmmaakkee happy. - - The `::::' helps avoid false matches with the AT&T System V UNIX style - ::== modifier and since substitution always occurs the ::::== form is - vaguely appropriate. - - ::::??==_s_t_r - As for ::::== but only if the variable does not already have a value. - - ::::++==_s_t_r - Append _s_t_r to the variable. - - ::::!!==_c_m_d - Assign the output of _c_m_d to the variable. - - ::[[_r_a_n_g_e]] - Selects one or more words from the value, or performs other opera- - tions related to the way in which the value is divided into words. - - Ordinarily, a value is treated as a sequence of words delimited by - white space. 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. For example, `::[[--11....11]]' selects all - the words from last to first. - - ** Causes subsequent modifiers to treat the value as a single - word (possibly containing embedded white space). Analogous - to the effect of "$*" in Bourne shell. - - 0 Means the same as `::[[**]]'. - - @@ Causes subsequent modifiers to treat the value as a sequence - of words delimited by white space. Analogous to the effect - of "$@" in Bourne shell. - - ## Returns the number of words in the value. - -IINNCCLLUUDDEE SSTTAATTEEMMEENNTTSS,, CCOONNDDIITTIIOONNAALLSS AANNDD FFOORR LLOOOOPPSS - Makefile inclusion, conditional structures and for loops reminiscent of - the C programming language are provided in bbmmaakkee. All such structures - are identified by a line beginning with a single dot (`.') character. - Files are included with either ..iinncclluuddee <_f_i_l_e> or ..iinncclluuddee "_f_i_l_e". Vari- - ables between the angle brackets or double quotes are expanded to form - the file name. If angle brackets are used, the included makefile is - expected to be in the system makefile directory. If double quotes are - used, the including makefile's directory and any directories specified - using the --II option are searched before the system makefile directory. - For compatibility with other versions of bbmmaakkee `include file ...' is also - accepted. If the include statement is written as ..--iinncclluuddee or as - ..ssiinncclluuddee then errors locating and/or opening include files are ignored. - - Conditional expressions are also preceded by a single dot as the first - character of a line. The possible conditionals are as follows: - - ..eerrrroorr _m_e_s_s_a_g_e - The message is printed along with the name of the makefile and - line number, then bbmmaakkee will exit. - - ..eexxppoorrtt _v_a_r_i_a_b_l_e _._._. - Export the specified global variable. If no variable list is - provided, all globals are exported except for internal variables - (those that start with `.'). This is not affected by the --XX - flag, so should be used with caution. For compatibility with - other bbmmaakkee programs `export variable=value' is also accepted. - - Appending a variable name to _._M_A_K_E_._E_X_P_O_R_T_E_D is equivalent to - exporting a variable. - - ..eexxppoorrtt--eennvv _v_a_r_i_a_b_l_e _._._. - The same as `.export', except that the variable is not appended - to _._M_A_K_E_._E_X_P_O_R_T_E_D. This allows exporting a value to the environ- - ment which is different from that used by bbmmaakkee internally. - - ..iinnffoo _m_e_s_s_a_g_e - The message is printed along with the name of the makefile and - line number. - - ..uunnddeeff _v_a_r_i_a_b_l_e - Un-define the specified global variable. Only global variables - may be un-defined. - - ..uunneexxppoorrtt _v_a_r_i_a_b_l_e _._._. - The opposite of `.export'. The specified global _v_a_r_i_a_b_l_e will be - removed from _._M_A_K_E_._E_X_P_O_R_T_E_D. If no variable list is provided, - all globals are unexported, and _._M_A_K_E_._E_X_P_O_R_T_E_D deleted. - - ..uunneexxppoorrtt--eennvv - Unexport all globals previously exported and clear the environ- - ment inherited from the parent. This operation will cause a mem- - ory leak of the original environment, so should be used spar- - ingly. Testing for _._M_A_K_E_._L_E_V_E_L being 0, would make sense. Also - note that any variables which originated in the parent environ- - ment should be explicitly preserved if desired. For example: - - .if ${.MAKE.LEVEL} == 0 - PATH := ${PATH} - .unexport-env - .export PATH - .endif - - Would result in an environment containing only `PATH', which is - the minimal useful environment. Actually `.MAKE.LEVEL' will also - be pushed into the new environment. - - ..wwaarrnniinngg _m_e_s_s_a_g_e - The message prefixed by `_w_a_r_n_i_n_g_:' is printed along with the name - of the makefile and line number. - - ..iiff [!]_e_x_p_r_e_s_s_i_o_n [_o_p_e_r_a_t_o_r _e_x_p_r_e_s_s_i_o_n _._._.] - Test the value of an expression. - - ..iiffddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.] - Test the value of a variable. - - ..iiffnnddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.] - Test the value of a variable. - - ..iiffmmaakkee [!]_t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.] - Test the target being built. - - ..iiffnnmmaakkee [!] _t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.] - Test the target being built. - - ..eellssee Reverse the sense of the last conditional. - - ..eelliiff [!] _e_x_p_r_e_s_s_i_o_n [_o_p_e_r_a_t_o_r _e_x_p_r_e_s_s_i_o_n _._._.] - A combination of `..eellssee' followed by `..iiff'. - - ..eelliiffddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.] - A combination of `..eellssee' followed by `..iiffddeeff'. - - ..eelliiffnnddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.] - A combination of `..eellssee' followed by `..iiffnnddeeff'. - - ..eelliiffmmaakkee [!]_t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.] - A combination of `..eellssee' followed by `..iiffmmaakkee'. - - ..eelliiffnnmmaakkee [!]_t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.] - A combination of `..eellssee' followed by `..iiffnnmmaakkee'. - - ..eennddiiff End the body of the conditional. - - The _o_p_e_r_a_t_o_r may be any one of the following: - - |||| Logical OR. - - &&&& Logical AND; of higher precedence than ``||''. - - As in C, bbmmaakkee will only evaluate a conditional as far as is necessary to - determine its value. Parentheses may be used to change the order of - evaluation. The boolean operator `!!' may be used to logically negate an - entire conditional. It is of higher precedence than `&&&&'. - - The value of _e_x_p_r_e_s_s_i_o_n may be any of the following: - - ddeeffiinneedd Takes a variable name as an argument and evaluates to true if - the variable has been defined. - - mmaakkee Takes a target name as an argument and evaluates to true if the - target was specified as part of bbmmaakkee's command line or was - declared the default target (either implicitly or explicitly, - see _._M_A_I_N) before the line containing the conditional. - - eemmppttyy Takes a variable, with possible modifiers, and evaluates to true - if the expansion of the variable would result in an empty - string. - - eexxiissttss Takes a file name as an argument and evaluates to true if the - file exists. The file is searched for on the system search path - (see _._P_A_T_H). - - ttaarrggeett Takes a target name as an argument and evaluates to true if the - target has been defined. - - ccoommmmaannddss - Takes a target name as an argument and evaluates to true if the - target has been defined and has commands associated with it. - - _E_x_p_r_e_s_s_i_o_n may also be an arithmetic or string comparison. Variable - expansion is performed on both sides of the comparison, after which the - integral values are compared. A value is interpreted as hexadecimal if - it is preceded by 0x, otherwise it is decimal; octal numbers are not sup- - ported. The standard C relational operators are all supported. If after - variable expansion, either the left or right hand side of a `====' or `!!==' - operator is not an integral value, then string comparison is performed - between the expanded variables. 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. Normally used to mark recursive - bbmmaakkee's. - - ..MMEETTAA Create a meta file for the target, even if it is flagged as - ..PPHHOONNYY, ..MMAAKKEE, or ..SSPPEECCIIAALL. Usage in conjunction with ..MMAAKKEE is - the most likely case. In "meta" mode, the target is out-of- - date if the meta file is missing. - - ..NNOOMMEETTAA Do not create a meta file for the target. Meta files are also - not created for ..PPHHOONNYY, ..MMAAKKEE, or ..SSPPEECCIIAALL targets. - - ..NNOOMMEETTAA__CCMMPP - Ignore differences in commands when deciding if target is out - of date. This is useful if the command contains a value which - always changes. If the number of commands change, though, the - target will still be out of date. - - ..NNOOPPAATTHH Do not search for the target in the directories specified by - ..PPAATTHH. - - ..NNOOTTMMAAIINN Normally bbmmaakkee selects the first target it encounters as the - default target to be built if no target was specified. This - source prevents this target from being selected. - - ..OOPPTTIIOONNAALL - If a target is marked with this attribute and bbmmaakkee can't fig- - ure out how to create it, it will ignore this fact and assume - the file isn't needed or already exists. - - ..PPHHOONNYY The target does not correspond to an actual file; it is always - considered to be out of date, and will not be created with the - --tt option. Suffix-transformation rules are not applied to - ..PPHHOONNYY targets. - - ..PPRREECCIIOOUUSS - When bbmmaakkee is interrupted, it normally removes any partially - made targets. This source prevents the target from being - removed. - - ..RREECCUURRSSIIVVEE - Synonym for ..MMAAKKEE. - - ..SSIILLEENNTT Do not echo any of the commands associated with this target, - exactly as if they all were preceded by an at sign (`@'). - - ..UUSSEE Turn the target into bbmmaakkee's version of a macro. 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. If the target already has commands, the - ..UUSSEE target's commands are appended to them. - - ..UUSSEEBBEEFFOORREE - Exactly like ..UUSSEE, but prepend the ..UUSSEEBBEEFFOORREE target commands - to the target. - - ..WWAAIITT If ..WWAAIITT appears in a dependency line, the sources that precede - it are made before the sources that succeed it in the line. - Since the dependents of files are not made until the file - itself could be made, this also stops the dependents being - built unless they are needed for another branch of the depen- - dency tree. 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. Only the shell script is used. The ..IIMMPPSSRRCC variable of a - target that inherits ..DDEEFFAAUULLTT's commands is set to the target's - own name. - - ..EENNDD Any command lines attached to this target are executed after - everything else is done. - - ..EERRRROORR Any command lines attached to this target are executed when - another target fails. The ..EERRRROORR__TTAARRGGEETT variable is set to the - target that failed. See also MMAAKKEE__PPRRIINNTT__VVAARR__OONN__EERRRROORR. - - ..IIGGNNOORREE Mark each of the sources with the ..IIGGNNOORREE attribute. If no - sources are specified, this is the equivalent of specifying the - --ii option. - - ..IINNTTEERRRRUUPPTT - If bbmmaakkee is interrupted, the commands for this target will be - executed. - - ..MMAAIINN If no target is specified when bbmmaakkee is invoked, this target - will be built. - - ..MMAAKKEEFFLLAAGGSS - This target provides a way to specify flags for bbmmaakkee when the - makefile is used. The flags are as if typed to the shell, - though the --ff option will have no effect. - - ..NNOOPPAATTHH Apply the ..NNOOPPAATTHH attribute to any specified sources. - - ..NNOOTTPPAARRAALLLLEELL - Disable parallel mode. - - ..NNOO__PPAARRAALLLLEELL - Synonym for ..NNOOTTPPAARRAALLLLEELL, for compatibility with other pmake - variants. - - ..OORRDDEERR The named targets are made in sequence. This ordering does not - add targets to the list of targets to be made. Since the depen- - dents of a target do not get built until the target itself could - be built, unless `a' is built by another part of the dependency - graph, the following is a dependency loop: - - .ORDER: b a - b: a - - The ordering imposed by ..OORRDDEERR is only relevant for parallel - makes. - - ..PPAATTHH The sources are directories which are to be searched for files - not found in the current directory. If no sources are speci- - fied, any previously specified directories are deleted. If the - source is the special ..DDOOTTLLAASSTT target, then the current working - directory is searched last. - - ..PPHHOONNYY Apply the ..PPHHOONNYY attribute to any specified sources. - - ..PPRREECCIIOOUUSS - Apply the ..PPRREECCIIOOUUSS attribute to any specified sources. If no - sources are specified, the ..PPRREECCIIOOUUSS attribute is applied to - every target in the file. - - ..SSHHEELLLL Sets the shell that bbmmaakkee will use to execute commands. The - sources are a set of _f_i_e_l_d_=_v_a_l_u_e pairs. - - _n_a_m_e This is the minimal specification, used to select - one of the builtin shell specs; _s_h, _k_s_h, and _c_s_h. - - _p_a_t_h Specifies the path to the shell. - - _h_a_s_E_r_r_C_t_l Indicates whether the shell supports exit on error. - - _c_h_e_c_k The command to turn on error checking. - - _i_g_n_o_r_e The command to disable error checking. - - _e_c_h_o The command to turn on echoing of commands executed. - - _q_u_i_e_t The command to turn off echoing of commands exe- - cuted. - - _f_i_l_t_e_r The output to filter after issuing the _q_u_i_e_t com- - mand. It is typically identical to _q_u_i_e_t. - - _e_r_r_F_l_a_g The flag to pass the shell to enable error checking. - - _e_c_h_o_F_l_a_g The flag to pass the shell to enable command echo- - ing. - - _n_e_w_l_i_n_e The string literal to pass the shell that results in - a single newline character when used outside of any - quoting characters. - Example: - - .SHELL: name=ksh path=/bin/ksh hasErrCtl=true \ - check="set -e" ignore="set +e" \ - echo="set -v" quiet="set +v" filter="set +v" \ - echoFlag=v errFlag=e newline="'\n'" - - ..SSIILLEENNTT Apply the ..SSIILLEENNTT attribute to any specified sources. If no - sources are specified, the ..SSIILLEENNTT attribute is applied to every - command in the file. - - ..SSUUFFFFIIXXEESS - Each source specifies a suffix to bbmmaakkee. If no sources are - specified, any previously specified suffixes are deleted. It - allows the creation of suffix-transformation rules. - - Example: - - .SUFFIXES: .o - .c.o: - cc -o ${.TARGET} -c ${.IMPSRC} - -EENNVVIIRROONNMMEENNTT - bbmmaakkee uses the following environment variables, if they exist: MACHINE, - MACHINE_ARCH, MAKE, MAKEFLAGS, MAKEOBJDIR, MAKEOBJDIRPREFIX, MAKESYSPATH, - PWD, and TMPDIR. - - MAKEOBJDIRPREFIX and MAKEOBJDIR may only be set in the environment or on - the command line to bbmmaakkee and not as makefile variables; see the descrip- - tion of `_._O_B_J_D_I_R' for more details. - -FFIILLEESS - .depend list of dependencies - Makefile list of dependencies - makefile list of dependencies - sys.mk system makefile - /usr/share/mk system makefile directory - -CCOOMMPPAATTIIBBIILLIITTYY - The basic make syntax is compatible between different versions of make, - however the special variables, variable modifiers and conditionals are - not. - - The way that parallel makes are scheduled changed in NetBSD 4.0 so that - .ORDER and .WAIT apply recursively to the dependent nodes. The algo- - rithms used may change again in the future. - - The way that .for loop variables are substituted changed after NetBSD 5.0 - so that they still appear to be variable expansions. In particular this - stops them being treated as syntax, and removes some obscure problems - using them in .if statements. - - Unlike other bbmmaakkee programs, this implementation by default executes all - commands for a given target using a single shell invocation. This is - done for both efficiency and to simplify error handling in remote command - invocations. Typically this is transparent to the user, unless the tar- - get commands change the current working directory using ``cd'' or - ``chdir''. To be compatible with Makefiles that do this, one can use --BB - to disable this behavior. - -SSEEEE AALLSSOO - mkdep(1) - -HHIISSTTOORRYY - bbmmaakkee is derived from NetBSD make(1).

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.

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 -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. -.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

The program referenced by these variables are -# expected to produce output like: -#.nf -# -# # 10 \"/usr/include/stdio.h\" 1 -# -#.fi -# This allows us to skip most of our processing. For lex,yacc -# and other source files, grep is probably just as quick and -# certainly more portable. -# -# If the "rc" file does not exist, we create it and attempt to -# find cpp or an equivalent cc invocation to assign to 'cpp_c'. -# -# AUTHOR: -# Simon J.
