       Basic Installation

          These are generic installation instructions.

          The ‘configure’ shell script attempts to guess correct values for
       various system-dependent variables used during compilation.  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, and a
       file ‘config.log’ containing compiler output (useful mainly for
       debugging ‘configure’).

          It can also use an optional file (typically called ‘config.cache’
       and enabled with ‘--cache-file=config.cache’ or simply ‘-C’) that saves
       the results of its tests to speed up reconfiguring.  (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 file ‘’ (or ‘’) is used to create
       ‘configure’ by a program called ‘autoconf’.  You only need
       ‘’ 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

         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:

            ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix

          *Note Defining Variables::, for more details.

       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 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 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’ 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:


       where SYSTEM can have one of these forms:

            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.

          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’.

       Sharing Defaults

          If you want to set default values for ‘configure’ scripts to share,
       you can create a site shell script called ‘’ that gives
       default values for variables like ‘CC’, ‘cache_file’, and ‘prefix’.
       ‘configure’ looks for ‘PREFIX/share/’ if it exists, then
       ‘PREFIX/etc/’ 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

          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

       will cause the specified gcc to be used as the C compiler (unless it is
       overridden in the site shell script).

       ‘configure’ Invocation

          ‘configure’ recognizes the following options to control how it

            Print a summary of the options to ‘configure’, and exit.

            Print the version of Autoconf used to generate the ‘configure’
            script, and exit.

            Enable the cache: use and save the results of the tests in FILE,
            traditionally ‘config.cache’.  FILE defaults to ‘/dev/null’ to
            disable caching.

            Alias for ‘--cache-file=config.cache’.

            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).

            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.  Run
       ‘configure --help’ for more details.
