   10: Basic Installation
   11: ==================
   13: Briefly, the shell commands `./configure; make; make install' should
   14: configure, build, and install this package.  The following
   15: more-detailed instructions are generic; see the `README' file for
   16: instructions specific to this package.
   18:    The `configure' shell script attempts to guess correct values for
   19: various system-dependent variables used during compilation.  It uses
   20: those values to create a `Makefile' in each directory of the package.
   21: It may also create one or more `.h' files containing system-dependent
   22: definitions.  Finally, it creates a shell script `config.status' that
   23: you can run in the future to recreate the current configuration, and a
   24: file `config.log' containing compiler output (useful mainly for
   25: debugging `configure').
   27:    It can also use an optional file (typically called `config.cache'
   28: and enabled with `--cache-file=config.cache' or simply `-C') that saves
   29: the results of its tests to speed up reconfiguring.  Caching is
   30: disabled by default to prevent problems with accidental use of stale
   31: cache files.
   33:    If you need to do unusual things to compile the package, please try
   34: to figure out how `configure' could check whether to do them, and mail
   35: diffs or instructions to the address given in the `README' so they can
   36: be considered for the next release.  If you are using the cache, and at
   37: some point `config.cache' contains results you don't want to keep, you
   38: may remove or edit it.
   40:    The file `' (or `') is used to create
   41: `configure' by a program called `autoconf'.  You need `' if
   42: you want to change it or regenerate `configure' using a newer version
   43: of `autoconf'.
   45: The simplest way to compile this package is:
   47:   1. `cd' to the directory containing the package's source code and type
   48:      `./configure' to configure the package for your system.
   50:      Running `configure' might take a while.  While running, it prints
   51:      some messages telling which features it is checking for.
   53:   2. Type `make' to compile the package.
   55:   3. Optionally, type `make check' to run any self-tests that come with
   56:      the package.
   58:   4. Type `make install' to install the programs and any data files and
   59:      documentation.
   61:   5. You can remove the program binaries and object files from the
   62:      source code directory by typing `make clean'.  To also remove the
   63:      files that `configure' created (so you can compile the package for
   64:      a different kind of computer), type `make distclean'.  There is
   65:      also a `make maintainer-clean' target, but that is intended mainly
   66:      for the package's developers.  If you use it, you may have to get
   67:      all sorts of other programs in order to regenerate files that came
   68:      with the distribution.
   70: Compilers and Options
   71: =====================
   73: Some systems require unusual options for compilation or linking that the
   74: `configure' script does not know about.  Run `./configure --help' for
   75: details on some of the pertinent environment variables.
   77:    You can give `configure' initial values for configuration parameters
   78: by setting variables in the command line or in the environment.  Here
   79: is an example:
   81:      ./configure CC=c99 CFLAGS=-g LIBS=-lposix
   83:    *Note Defining Variables::, for more details.
   85: Compiling For Multiple Architectures
   86: ====================================
   88: You can compile the package for more than one kind of computer at the
   89: same time, by placing the object files for each architecture in their
   90: own directory.  To do this, you can use GNU `make'.  `cd' to the
   91: directory where you want the object files and executables to go and run
   92: the `configure' script.  `configure' automatically checks for the
   93: source code in the directory that `configure' is in and in `..'.
   95:    With a non-GNU `make', it is safer to compile the package for one
   96: architecture at a time in the source code directory.  After you have
   97: installed the package for one architecture, use `make distclean' before
   98: reconfiguring for another architecture.
  100: Installation Names
  101: ==================
  103: By default, `make install' installs the package's commands under
  104: `/usr/local/bin', include files under `/usr/local/include', etc.  You
  105: can specify an installation prefix other than `/usr/local' by giving
  106: `configure' the option `--prefix=PREFIX'.
  108:    You can specify separate installation prefixes for
  109: architecture-specific files and architecture-independent files.  If you
  110: pass the option `--exec-prefix=PREFIX' to `configure', the package uses
  111: PREFIX as the prefix for installing programs and libraries.
  112: Documentation and other data files still use the regular prefix.
  114:    In addition, if you use an unusual directory layout you can give
  115: options like `--bindir=DIR' to specify different values for particular
  116: kinds of files.  Run `configure --help' for a list of the directories
  117: you can set and what kinds of files go in them.
  119:    If the package supports it, you can cause programs to be installed
  120: with an extra prefix or suffix on their names by giving `configure' the
  121: option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
  123: Optional Features
  124: =================
  126: Some packages pay attention to `--enable-FEATURE' options to
  127: `configure', where FEATURE indicates an optional part of the package.
  128: They may also pay attention to `--with-PACKAGE' options, where PACKAGE
  129: is something like `gnu-as' or `x' (for the X Window System).  The
  130: `README' should mention any `--enable-' and `--with-' options that the
  131: package recognizes.
  133:    For packages that use the X Window System, `configure' can usually
  134: find the X include and library files automatically, but if it doesn't,
  135: you can use the `configure' options `--x-includes=DIR' and
  136: `--x-libraries=DIR' to specify their locations.
  138: Specifying the System Type
  139: ==========================
  141: There may be some features `configure' cannot figure out automatically,
  142: but needs to determine by the type of machine the package will run on.
  143: Usually, assuming the package is built to be run on the _same_
  144: architectures, `configure' can figure that out, but if it prints a
  145: message saying it cannot guess the machine type, give it the
  146: `--build=TYPE' option.  TYPE can either be a short name for the system
  147: type, such as `sun4', or a canonical name which has the form:
  151: where SYSTEM can have one of these forms:
  153:      OS KERNEL-OS
  155:    See the file `config.sub' for the possible values of each field.  If
  156: `config.sub' isn't included in this package, then this package doesn't
  157: need to know the machine type.
  159:    If you are _building_ compiler tools for cross-compiling, you should
  160: use the option `--target=TYPE' to select the type of system they will
  161: produce code for.
  163:    If you want to _use_ a cross compiler, that generates code for a
  164: platform different from the build platform, you should specify the
  165: "host" platform (i.e., that on which the generated programs will
  166: eventually be run) with `--host=TYPE'.
  168: Sharing Defaults
  169: ================
  171: If you want to set default values for `configure' scripts to share, you
  172: can create a site shell script called `' that gives default
  173: values for variables like `CC', `cache_file', and `prefix'.
  174: `configure' looks for `PREFIX/share/' if it exists, then
  175: `PREFIX/etc/' if it exists.  Or, you can set the
  176: `CONFIG_SITE' environment variable to the location of the site script.
  177: A warning: not all `configure' scripts look for a site script.
  179: Defining Variables
  180: ==================
  182: Variables not defined in a site shell script can be set in the
  183: environment passed to `configure'.  However, some packages may run
  184: configure again during the build, and the customized values of these
  185: variables may be lost.  In order to avoid this problem, you should set
  186: them in the `configure' command line, using `VAR=value'.  For example:
  188:      ./configure CC=/usr/local2/bin/gcc
  190: causes the specified `gcc' to be used as the C compiler (unless it is
  191: overridden in the site shell script).
  193: Unfortunately, this technique does not work for `CONFIG_SHELL' due to
  194: an Autoconf bug.  Until the bug is fixed you can use this workaround:
  196:      CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
  198: `configure' Invocation
  199: ======================
  201: `configure' recognizes the following options to control how it operates.
  203: `--help'
  204: `-h'
  205:      Print a summary of the options to `configure', and exit.
  207: `--version'
  208: `-V'
  209:      Print the version of Autoconf used to generate the `configure'
  210:      script, and exit.
  212: `--cache-file=FILE'
  213:      Enable the cache: use and save the results of the tests in FILE,
  214:      traditionally `config.cache'.  FILE defaults to `/dev/null' to
  215:      disable caching.
  217: `--config-cache'
  218: `-C'
  219:      Alias for `--cache-file=config.cache'.
  221: `--quiet'
  222: `--silent'
  223: `-q'
  224:      Do not print messages saying which checks are being made.  To
  225:      suppress all normal output, redirect it to `/dev/null' (any error
  226:      messages will still be shown).
  228: `--srcdir=DIR'
  229:      Look for the package's source code in directory DIR.  Usually
  230:      `configure' can determine that directory automatically.
  232: `configure' also accepts some other, not widely useful, options.  Run
  233: `configure --help' for more details.
