Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). -1.

(Caching is +disabled by default to prevent problems with accidental use of stale +cache files.) + + 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 you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. -The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation, and -creates the Makefile(s) (one in each subdirectory of the source -directory). In some packages it creates a C header file containing -system-dependent definitions. It also creates a file `config.status' -that you can run in the future to recreate the current configuration. + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You only need +`configure.ac' if you want to change it or regenerate `configure' using +a newer version of `autoconf'. + +The simplest way to compile this package is: -Running `configure' takes a minute or two. While it is running, it -prints some messages that tell what it is doing. If you don't want to -see the messages, run `configure' with its standard output redirected -to `/dev/null'; for example, `./configure >/dev/null'. + 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. -To compile the package in a different directory from the one -containing the source code, 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 -`configure'. `configure' automatically checks for the source code in -the directory that `configure' is in and in `..'. If for some reason -`configure' is not in the source code directory that you are -configuring, then it will report that it can't find the source code. -In that case, run `configure' with the option `--srcdir=DIR', where -DIR is the directory that contains the source code. + 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. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: -By default, `make install' will install the package's files in -/usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify -an installation prefix other than /usr/local by giving `configure' the -option `--prefix=PATH'. Alternately, you can do so by giving a value -for the `prefix' variable when you run `make', e.g., - make prefix=/usr/gnu + ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== -You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If -you give `configure' the option `--exec_prefix=PATH' or set the -`make' variable `exec_prefix' to PATH, the package will use PATH as -the prefix for installing programs and libraries. Data files and -documentation will still use the regular prefix. Normally, all files -are installed using the regular prefix. + 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 support 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 tell `configure' to figure out the configuration for your -system, and record it in `config.status', without actually configuring -the package (creating `Makefile's and perhaps a configuration header -file). To do this, give `configure' the `--no-create' option. Later, -you can run `./config.status' to actually configure the package. This -option is useful mainly in `Makefile' rules for updating `config.status' -and `Makefile'. You can also give `config.status' the `--recheck' -option, which makes it re-run `configure' with the same arguments you -used before. This is useful if you change `configure'. + 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'. -`configure' ignores any other arguments that you give it. +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. -If your system requires unusual options for compilation or linking -that `configure' doesn't know about, you can give `configure' initial -values for some variables by setting them in the environment. In -Bourne-compatible shells, you can do that on the command line like -this: - CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: -The `make' variables that you might want to override with environment -variables when running `configure' are: + OS KERNEL-OS + + 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 machine type. -(For these variables, any value given in the environment overrides the -value that `configure' would choose:) -CC C compiler program. - Default is `cc', or `gcc' if `gcc' is in your PATH. -INSTALL Program to use to install files. - Default is `install' if you have it, `cp' otherwise. + If you are _building_ compiler tools for cross-compiling, you should +use the `--target=TYPE' option to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. -(For these variables, any value given in the environment is added to -the value that `configure' chooses:) -DEFS Configuration options, in the form `-Dfoo -Dbar ...' -LIBS Libraries to link with, in the form `-lfoo -lbar ...' +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. + +Defining Variables +================== -If you need to do unusual things to compile the package, we encourage -you to figure out how `configure' could check whether to do them, and -mail diffs or instructions to the address given in the README so we -can include them in the next release. + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc -2. Type `make' to compile the package. If you want, you can override -the `make' variables CXXFLAGS, CFLAGS, FFLAGS, and LDFLAGS like this: +will cause the specified gcc to be used as the C compiler (unless it is +overridden in the site shell script). - make CXXFLAGS=-O2 CFLAGS=-O2 FFLAGS=-O LDFLAGS=-s +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. -3. If the package comes with self-tests and you want to run them, -type `make check'. If you're not sure whether there are any, try it; -if `make' responds with something like - make: *** No way to make target `check'. Stop. -then the package does not come with self-tests. +`--help' +`-h' + Print a summary of the options to `configure', and exit. -4. Type `make install' to install programs, data files, and -documentation. +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. -5. You can remove the program binaries and object files from the -source directory by typing `make clean'. To also remove the -Makefile(s), the header file containing system-dependent definitions -(if the package uses one), and `config.status' (all the files that -`configure' created), type `make distclean'. +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. -The file `configure.in' is used as a template to create `configure' by -a program called `autoconf'. You will only need it if you want to -regenerate `configure' using a newer version of `autoconf'. +`--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. + +`configure' also accepts some other, not widely useful, options.
