It uses -those values to create a `Makefile' in each directory of the package. -It may also create one or more `.h' files containing system-dependent -definitions. Finally, it creates a shell script `config.status' that -you can run in the future to recreate the current configuration, a file -`config.cache' that saves the results of its tests to speed up -reconfiguring, and a file `config.log' containing compiler output -(useful mainly for debugging `configure'). - - If you need to do unusual things to compile the package, please try -to figure out how `configure' could check whether to do them, and mail -diffs or instructions to the address given in the `README' so they can -be considered for the next release. If at some point `config.cache' -contains results you don't want to keep, you may remove or edit it. - - The file `configure.in' is used to create `configure' by a program -called `autoconf'. You only need `configure.in' if you want to change -it or regenerate `configure' using a newer version of `autoconf'. - -The simplest way to compile this package is: - - 1. `cd' to the directory containing the package's source code and type - `./configure' to configure the package for your system. If you're - using `csh' on an old version of System V, you might need to type - `sh ./configure' instead to prevent `csh' from trying to execute - `configure' itself. - - Running `configure' takes awhile. While running, it prints some - messages telling which features it is checking for. - - 2. Type `make' to compile the package. - - 3. Optionally, type `make check' to run any self-tests that come with - the package. - - 4. Type `make install' to install the programs and any data files and - documentation. - - 5. You can remove the program binaries and object files from the - source code directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile the package for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the package's developers. If you use it, you may have to get - all sorts of other programs in order to regenerate files that came - with the distribution. - -Compilers and Options -===================== - - Some systems require unusual options for compilation or linking that -the `configure' script does not know about. You can give `configure' -initial values for variables by setting them in the environment. Using -a Bourne-compatible shell, you can do that on the command line like -this: - CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure - -Or on systems that have the `env' program, you can do it like this: - env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure - -Compiling For Multiple Architectures -==================================== - - You can compile the package for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you must use a version of `make' that -supports the `VPATH' variable, such as GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. - - If you have to use a `make' that does not supports the `VPATH' -variable, you have to compile the package for one architecture at a time -in the source code directory. After you have installed the package for -one architecture, use `make distclean' before reconfiguring for another -architecture. - -Installation Names -================== - - By default, `make install' will install the package's files in -`/usr/local/bin', `/usr/local/man', etc. You can specify an -installation prefix other than `/usr/local' by giving `configure' the -option `--prefix=PATH'. - - You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If you -give `configure' the option `--exec-prefix=PATH', the package will use -PATH as the prefix for installing programs and libraries. -Documentation and other data files will still use the regular prefix. - - In addition, if you use an unusual directory layout you can give -options like `--bindir=PATH' to specify different values for particular -kinds of files. Run `configure --help' for a list of the directories -you can set and what kinds of files go in them. - - If the package supports it, you can cause programs to be installed -with an extra prefix or suffix on their names by giving `configure' the -option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. - -Optional Features -================= - - Some packages pay attention to `--enable-FEATURE' options to -`configure', where FEATURE indicates an optional part of the package. -They may also pay attention to `--with-PACKAGE' options, where PACKAGE -is something like `gnu-as' or `x' (for the X Window System). The -`README' should mention any `--enable-' and `--with-' options that the -package recognizes. - - For packages that use the X Window System, `configure' can usually -find the X include and library files automatically, but if it doesn't, -you can use the `configure' options `--x-includes=DIR' and -`--x-libraries=DIR' to specify their locations. - -Specifying the System Type -========================== - - There may be some features `configure' can not figure out -automatically, but needs to determine by the type of host the package -will run on. Usually `configure' can figure that out, but if it prints -a message saying it can not guess the host type, give it the -`--host=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name with three fields: - CPU-COMPANY-SYSTEM - -See the file `config.sub' for the possible values of each field. If -`config.sub' isn't included in this package, then this package doesn't -need to know the host type. - - If you are building compiler tools for cross-compiling, you can also -use the `--target=TYPE' option to select the type of system they will -produce code for and the `--build=TYPE' option to select the type of -system on which you are compiling the package. - -Sharing Defaults -================ - - If you want to set default values for `configure' scripts to share, -you can create a site shell script called `config.site' that gives -default values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: not all `configure' scripts look for a site script. - -Operation Controls -================== - - `configure' recognizes the following options to control how it -operates. - -`--cache-file=FILE' - Use and save the results of the tests in FILE instead of - `./config.cache'. Set FILE to `/dev/null' to disable caching, for - debugging `configure'. - -`--help' - Print a summary of the options to `configure', and exit. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. To - suppress all normal output, redirect it to `/dev/null' (any error - messages will still be shown). - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`--version' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`configure' also accepts some other, not widely useful, options. diff --git a/contrib/ntp/arlib/Makefile.am b/contrib/ntp/arlib/Makefile.am deleted file mode 100644 index c0b4094..0000000 --- a/contrib/ntp/arlib/Makefile.am +++ /dev/null @@ -1,15 +0,0 @@ -AUTOMAKE_OPTIONS = foreign # ansi2knr -

To use this -set of routines properly, the presence of the -.B "BIND 4.8" -resolve -libraries is required (or any library derived from it). -.PP - This library should be used in conjunction with -.B select(2) -to wait for -the name server's reply to arrive or the lookup to timeout. -.PP - To open a fd for talking to the name server, either -.B ar_open() -or -ar_init() -must be used. -.B ar_open() - will open either a datagram socket -or a virtual circuit with the name server, depending on the flags -set in the _res structure (see -.B resolv(5) -). In both cases, if the socket - -> i -.B ar_init() -is -used to both open the socket (as in -.B ar_open() -) and initialize the -queues used by this library. The values recognized as parameters to -.B ar_init() -are: - -.RS -#define ARES_INITLIST 1 -.RE -.RS -#define ARES_CALLINIT 2 -.RE -.RS -#define ARES_INITSOCK 4 -.RE -.RS -#define ARES_INITDEBG 8 -.RE - - ARES_INITLIST initializes the list of queries waiting for replies. -ARES_CALLINIT is a flag which when set causes -.B res_init() -to be called. -ARES_INITSOCK will close the current socket if it is open and call -.B ar_open() -to open a new one, returning the fd for that socket. -ARES_INITDEBG sets the RES_DEBUG flag of the -.B _res -structure. -ARES_INITCACH is as yet, unused and is for future use where the library -keeps its own cache of replies. - - To send a query about either a hostname or an IP number, -.B ar_gethostbyname() -and -.B ar_gethostbyaddr() -must be used. Each takes -either a pointer to the hostname or the IP number respectively for use -when making the query. In addition to this, both (optionally) can be -passed a pointer to data, dataptr, with the size also passed which can -be used for identifying individual queries. A copy of the area pointed -to is made if dataptr is non NULL and size is non zero. These functions -will always return NULL unless the answer to the query is found in -internal caches. A new flag, RES_CHECKPTR is checked during the -processing of answers for -.B ar_gethostbyname() -which will automatically -cause a reverse lookup to be queued, causing a failure if that reply -differs from the original. - - To check for a query, -.B ar_answer() -is called with a pointer to an area -of memory which is sufficient to hold what was originally passed via -.B ar_gethostbyname() -or -.B ar_gethostbyaddr() -through dataptr. If an answer -is found, a pointer to the host information is returned and the data -segment copied if dataptr is non NULL and it was originally passed. The -size of the copied data is the smaller of the passed size and that of -original data stored. - - To expire old queries, -.B ar_timeout() -is called with the 'current' time -(or the time for which you want to do timeouts for). If a queue entry -is too old, it will be expired when it has exhausted all available avenues -for lookups and the data segment for the expired query copied into -dataptr. The size of the copied data is the smaller of the passed size -and that of the original stored data. Only 1 entry is thus expired with -each call, requiring that it be called immediately after an expiration -to check for others. In addition to expiring lookups, -.B ar_timeout() -also -triggers resends of queries and the searching of the domain tree for the -host, the latter works from the -.B _res -structure of -.B resolv(5). - - To delete entries from the queue, -.B ar_delete() -can be used and by -passing the pointer and size of the data segment, all queries have their -data segments checked (if present) for an exact match, being deleted if -and only if there is a match. A NULL pointer passed to ar_deleted() -matches all queries which were called with a NULL dataptr parameter. -The amount of data compared is the smaller of the size passed and that -of the data stored for the queue entry being compared. - - To close a socket opened by -.B ar_open() -, -.B ar_close() -should be used so -that it is closed and also marked closed within this library. - - -.SH DIAGNOSIS - -.B ar_open() -returns -1 if a socket isn't open and could not be opened; -otherwise returns the current fd open or the fd it opened. - -.B ar_init() -returns -1 for any errors, the value returned by -.B res_init() -if -.B res_init() -was called, the return value for -.B ar_open() -if that was -called or the current socket open if 0 is passed and a socket is open. -If neither -.B res_init() -or -.B ar_open() -are called and the flags are non-zero, -2 is returned. - -.B ar_gethostbyaddr() -and -.B ar_gethostbyname() -will always return NULL in this version but may return a pointer to a hostent -structure if a cache is being used and the answer is found in the cache. - -.B ar_answer() -returns NULL if the answer is either not found or the -query returned an error and another attempt at a lookup is attempted. -If an answer was found, it returned a pointer to this structure and -the contents of the data segment copied over. - -.B ar_timeout() -returns the time when it should be called next or 0 if -there are no queries in the queue to be checked later. If any queries -are expired, the data segment is copied over if dataptr is non NULL. - -.B ar_delete() -returns the number of entries that were found to match -and consequently deleted. - -.SH SEE ALSO - -gethostbyaddr(3), gethostbyname(3), resolv(5) - -.SH FILES -.nf -arlib.h -/usr/include/resolv.h -/usr/include/arpa/nameser.h -/etc/resolv.conf - -.SH BUGS - -The results of a successful call to ar_answer() destroy the structure -for any previous calls. - -.SH AUTHOR - -Darren Reed.
