    1: Installation Instructions
    2: *************************

   10: Basic Installation
   11: ==================
   13: These are generic installation instructions.
   15:    The `configure' shell script attempts to guess correct values for
   16: various system-dependent variables used during compilation.  It uses
   17: those values to create a `Makefile' in each directory of the package.
   18: It may also create one or more `.h' files containing system-dependent
   19: definitions.  Finally, it creates a shell script `config.status' that
   20: you can run in the future to recreate the current configuration, and a
   21: file `config.log' containing compiler output (useful mainly for
   22: debugging `configure').
   24:    It can also use an optional file (typically called `config.cache'
   25: and enabled with `--cache-file=config.cache' or simply `-C') that saves
   26: the results of its tests to speed up reconfiguring.  (Caching is
   27: disabled by default to prevent problems with accidental use of stale
   28: cache files.)
   30:    If you need to do unusual things to compile the package, please try
   31: to figure out how `configure' could check whether to do them, and mail
   32: diffs or instructions to the address given in the `README' so they can
   33: be considered for the next release.  If you are using the cache, and at
   34: some point `config.cache' contains results you don't want to keep, you
   35: may remove or edit it.
   37:    The file `' (or `') is used to create
   38: `configure' by a program called `autoconf'.  You only need
   39: `' if you want to change it or regenerate `configure' using
   40: a newer version of `autoconf'.
   42: The simplest way to compile this package is:
   44:   1. `cd' to the directory containing the package's source code and type
   45:      `./configure' to configure the package for your system.  If you're
   46:      using `csh' on an old version of System V, you might need to type
   47:      `sh ./configure' instead to prevent `csh' from trying to execute
   48:      `configure' itself.
   50:      Running `configure' takes awhile.  While running, it prints some
   51:      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=c89 CFLAGS=-O2 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 must use a version of `make' that
   91: supports the `VPATH' variable, such as GNU `make'.  `cd' to the
   92: directory where you want the object files and executables to go and run
   93: the `configure' script.  `configure' automatically checks for the
   94: source code in the directory that `configure' is in and in `..'.
   96:    If you have to use a `make' that does not support the `VPATH'
   97: variable, you have to compile the package for one architecture at a
   98: time in the source code directory.  After you have installed the
   99: package for one architecture, use `make distclean' before reconfiguring
  100: for another architecture.
  102: Installation Names
  103: ==================
  105: By default, `make install' will install the package's files in
  106: `/usr/local/bin', `/usr/local/man', etc.  You can specify an
  107: installation prefix other than `/usr/local' by giving `configure' the
  108: option `--prefix=PREFIX'.
  110:    You can specify separate installation prefixes for
  111: architecture-specific files and architecture-independent files.  If you
  112: give `configure' the option `--exec-prefix=PREFIX', the package will
  113: use PREFIX as the prefix for installing programs and libraries.
  114: Documentation and other data files will still use the regular prefix.
  116:    In addition, if you use an unusual directory layout you can give
  117: options like `--bindir=DIR' to specify different values for particular
  118: kinds of files.  Run `configure --help' for a list of the directories
  119: you can set and what kinds of files go in them.
  121:    If the package supports it, you can cause programs to be installed
  122: with an extra prefix or suffix on their names by giving `configure' the
  123: option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
  125: Optional Features
  126: =================
  128: Some packages pay attention to `--enable-FEATURE' options to
  129: `configure', where FEATURE indicates an optional part of the package.
  130: They may also pay attention to `--with-PACKAGE' options, where PACKAGE
  131: is something like `gnu-as' or `x' (for the X Window System).  The
  132: `README' should mention any `--enable-' and `--with-' options that the
  133: package recognizes.
  135:    For packages that use the X Window System, `configure' can usually
  136: find the X include and library files automatically, but if it doesn't,
  137: you can use the `configure' options `--x-includes=DIR' and
  138: `--x-libraries=DIR' to specify their locations.
  140: Specifying the System Type
  141: ==========================
  143: There may be some features `configure' cannot figure out automatically,
  144: but needs to determine by the type of machine the package will run on.
  145: Usually, assuming the package is built to be run on the _same_
  146: architectures, `configure' can figure that out, but if it prints a
  147: message saying it cannot guess the machine type, give it the
  148: `--build=TYPE' option.  TYPE can either be a short name for the system
  149: type, such as `sun4', or a canonical name which has the form:
  153: where SYSTEM can have one of these forms:
  155:      OS KERNEL-OS
  157:    See the file `config.sub' for the possible values of each field.  If
  158: `config.sub' isn't included in this package, then this package doesn't
  159: need to know the machine type.
  161:    If you are _building_ compiler tools for cross-compiling, you should
  162: use the `--target=TYPE' option to select the type of system they will
  163: produce code for.
  165:    If you want to _use_ a cross compiler, that generates code for a
  166: platform different from the build platform, you should specify the
  167: "host" platform (i.e., that on which the generated programs will
  168: eventually be run) with `--host=TYPE'.
  170: Sharing Defaults
  171: ================
  173: If you want to set default values for `configure' scripts to share, you
  174: can create a site shell script called `' that gives default
  175: values for variables like `CC', `cache_file', and `prefix'.
  176: `configure' looks for `PREFIX/share/' if it exists, then
  177: `PREFIX/etc/' if it exists.  Or, you can set the
  178: `CONFIG_SITE' environment variable to the location of the site script.
  179: A warning: not all `configure' scripts look for a site script.
  181: Defining Variables
  182: ==================
  184: Variables not defined in a site shell script can be set in the
  185: environment passed to `configure'.  However, some packages may run
  186: configure again during the build, and the customized values of these
  187: variables may be lost.  In order to avoid this problem, you should set
  188: them in the `configure' command line, using `VAR=value'.  For example:
  190:      ./configure CC=/usr/local2/bin/gcc
  192: causes the specified `gcc' to be used as the C compiler (unless it is
  193: overridden in the site shell script).  Here is a another example:
  195:      /bin/bash ./configure CONFIG_SHELL=/bin/bash
  197: Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
  198: configuration-related scripts to be executed by `/bin/bash'.
  200: `configure' Invocation
  201: ======================
  203: `configure' recognizes the following options to control how it operates.
  205: `--help'
  206: `-h'
  207:      Print a summary of the options to `configure', and exit.
  209: `--version'
  210: `-V'
  211:      Print the version of Autoconf used to generate the `configure'
  212:      script, and exit.
  214: `--cache-file=FILE'
  215:      Enable the cache: use and save the results of the tests in FILE,
  216:      traditionally `config.cache'.  FILE defaults to `/dev/null' to
  217:      disable caching.
  219: `--config-cache'
  220: `-C'
  221:      Alias for `--cache-file=config.cache'.
  223: `--quiet'
  224: `--silent'
  225: `-q'
  226:      Do not print messages saying which checks are being made.  To
  227:      suppress all normal output, redirect it to `/dev/null' (any error
  228:      messages will still be shown).
  230: `--srcdir=DIR'
  231:      Look for the package's source code in directory DIR.  Usually
  232:      `configure' can determine that directory automatically.
  234: `configure' also accepts some other, not widely useful, options.  Run
  235: `configure --help' for more details.
