-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 `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:

-

-  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.  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' installs the package's commands under

-`/usr/local/bin', include files under `/usr/local/include', etc.  You

-can specify an installation prefix other than `/usr/local' by giving

-`configure' the option `--prefix=PREFIX'.

-

-   You can specify separate installation prefixes for

-architecture-specific files and architecture-independent files.  If you

-pass the option `--exec-prefix=PREFIX' to `configure', the package uses

-PREFIX as the prefix for installing programs and libraries.

-Documentation and other data files still use the regular prefix.

-

-   In addition, if you use an unusual directory layout you can give

-options like `--bindir=DIR' 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:

-

-     CPU-COMPANY-SYSTEM

-

-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 option `--target=TYPE' 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 `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

-==================

-

-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

-

-causes the specified `gcc' to be used as the C compiler (unless it is

-overridden in the site shell script).  Here is a another example:

-

-     /bin/bash ./configure CONFIG_SHELL=/bin/bash

-

-Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent

-configuration-related scripts to be executed by `/bin/bash'.

-

-`configure' Invocation

-======================

-

-`configure' recognizes the following options to control how it operates.

-

-`--help'

-`-h'

-     Print a summary of the options to `configure', and exit.

-

-`--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.

-

-`--config-cache'

-`-C'

-     Alias for `--cache-file=config.cache'.

-

-`--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.  Run

-`configure --help' for more details.
