Basic Installation
|
|
|
|
|
==================
|
|
|
|
|
|
|
|
|
|
Briefly, the shell commands `./configure; make; make install' should
|
|
|
|
|
configure, build, and install this package. The following
|
|
|
|
|
more-detailed instructions are generic; see the `README' file for
|
|
|
|
|
instructions specific to this package.
|
|
|
|
|
|
|
|
|
|
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 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.
|
|
|
|
|
|
|
|
|
|
Running `configure' might take a while. 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.
|
|
|
|
|
|
|
|
|
|
6. Often, you can also type `make uninstall' to remove the installed
|
|
|
|
|
files again.
|
|
|
|
|
|
|
|
|
|
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=c99 CFLAGS=-g 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 can use 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 `..'.
|
|
|
|
|
|
|
|
|
|
With a non-GNU `make', it is safer 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.
|
|
|
|
|
|
|
|
|
|
On MacOS X 10.5 and later systems, you can create libraries and
|
|
|
|
|
executables that work on multiple system types--known as "fat" or
|
|
|
|
|
"universal" binaries--by specifying multiple `-arch' options to the
|
|
|
|
|
compiler but only a single `-arch' option to the preprocessor. Like
|
|
|
|
|
this:
|
|
|
|
|
|
|
|
|
|
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
|
|
|
|
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
|
|
|
|
CPP="gcc -E" CXXCPP="g++ -E"
|
|
|
|
|
|
|
|
|
|
This is not guaranteed to produce working output in all cases, you
|
|
|
|
|
may have to build one architecture at a time and combine the results
|
|
|
|
|
using the `lipo' tool if you have problems.
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
Particular systems
|
|
|
|
|
==================
|
|
|
|
|
|
|
|
|
|
On HP-UX, the default C compiler is not ANSI C compatible. If GNU
|
|
|
|
|
CC is not installed, it is recommended to use the following options in
|
|
|
|
|
order to use an ANSI C compiler:
|
|
|
|
|
|
|
|
|
|
./configure CC="cc -Ae"
|
|
|
|
|
|
|
|
|
|
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
|
|
|
|
|
|
|
|
|
|
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
|
|
|
|
|
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
|
|
|
|
|
a workaround. If GNU CC is not installed, it is therefore recommended
|
|
|
|
|
to try
|
|
|
|
|
|
|
|
|
|
./configure CC="cc"
|
|
|
|
|
|
|
|
|
|
and if that doesn't work, try
|
|
|
|
|
|
|
|
|
|
./configure CC="cc -nodtk"
|
|
|
|
|
|
|
|
|
|
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).
|
|
|
|
|
|
|
|
|
|
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
|
|
|
|
|
an Autoconf bug. Until the bug is fixed you can use this workaround:
|
|
|
|
|
|
|
|
|
|
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
|
|
|
|
|
|
|
|
|
|
`configure' Invocation
|
|
|
|
|
======================
|
|
|
|
|
|
|
|
|
|
`configure' recognizes the following options to control how it
|
|
|
|
|
operates.
|
|
|
|
|
|
|
|
|
|
`--help'
|
|
|
|
|
`-h'
|
|
|
|
|
Print a summary of all of the options to `configure', and exit.
|
|
|
|
|
|
|
|
|
|
`--help=short'
|
|
|
|
|
`--help=recursive'
|
|
|
|
|
Print a summary of the options unique to this package's
|
|
|
|
|
`configure', and exit. The `short' variant lists options used
|
|
|
|
|
only in the top level, while the `recursive' variant lists options
|
|
|
|
|
also present in any nested packages.
|
|
|
|
|
|
|
|
|
|
`--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.
|
|
|
|
|
|
|
|
|
|
`--prefix=DIR'
|
|
|
|
|
Use DIR as the installation prefix. *Note Installation Names::
|
|
|
|
|
for more details, including other options available for fine-tuning
|
|
|
|
|
the installation locations.
|
|
|
|
|
|
|
|
|
|
`--no-create'
|
|
|
|
|
`-n'
|
|
|
|
|
Run the configure checks, but stop before creating any output
|
|
|
|
|
files.
|
|
|
|
|
|
|
|
|
|
`configure' also accepts some other, not widely useful, options. Run
|
|
|
|
|
`configure --help' for more details.

Basic Installation
|
|
|
|
|
==================
|
|
|
|
|
|
|
|
|
|
Briefly, the shell commands `./configure; make; make install' should
|
|
|
|
|
configure, build, and install this package. The following
|
|
|
|
|
more-detailed instructions are generic; see the `README' file for
|
|
|
|
|
instructions specific to this package.
|
|
|
|
|
|
|
|
|
|
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 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.
|
|
|
|
|
|
|
|
|
|
Running `configure' might take a while. 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.
|
|
|
|
|
|
|
|
|
|
6. Often, you can also type `make uninstall' to remove the installed
|
|
|
|
|
files again.

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=c99 CFLAGS=-g 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 can use 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 `..'.
|
|
|
|
|
|
|
|
|
|
With a non-GNU `make', it is safer 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.
|
|
|
|
|
|
|
|
|
|
On MacOS X 10.5 and later systems, you can create libraries and
|
|
|
|
|
executables that work on multiple system types--known as "fat" or
|
|
|
|
|
"universal" binaries--by specifying multiple `-arch' options to the
|
|
|
|
|
compiler but only a single `-arch' option to the preprocessor. Like
|
|
|
|
|
this:
|
|
|
|
|
|
|
|
|
|
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
|
|
|
|
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
|
|
|
|
CPP="gcc -E" CXXCPP="g++ -E"
|
|
|
|
|
|
|
|
|
|
This is not guaranteed to produce working output in all cases, you
|
|
|
|
|
may have to build one architecture at a time and combine the results
|
|
|
|
|
using the `lipo' tool if you have problems.
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
Particular systems
|
|
|
|
|
==================
|
|
|
|
|
|
|
|
|
|
On HP-UX, the default C compiler is not ANSI C compatible. If GNU
|
|
|
|
|
CC is not installed, it is recommended to use the following options in
|
|
|
|
|
order to use an ANSI C compiler:
|
|
|
|
|
|
|
|
|
|
./configure CC="cc -Ae"
|
|
|
|
|
|
|
|
|
|
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
|
|
|
|
|
|
|
|
|
|
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
|
|
|
|
|
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
|
|
|
|
|
a workaround. If GNU CC is not installed, it is therefore recommended
|
|
|
|
|
to try
|
|
|
|
|
|
|
|
|
|
./configure CC="cc"
|
|
|
|
|
|
|
|
|
|
and if that doesn't work, try
|
|
|
|
|
|
|
|
|
|
./configure CC="cc -nodtk"
|
|
|
|
|
|
|
|
|
|
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).
|
|
|
|
|
|
|
|
|
|
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
|
|
|
|
|
an Autoconf bug. Until the bug is fixed you can use this workaround:
|
|
|
|
|
|
|
|
|
|
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
|
|
|
|
|
|
|
|
|
|
`configure' Invocation
|
|
|
|
|
======================
|
|
|
|
|
|
|
|
|
|
`configure' recognizes the following options to control how it
|
|
|
|
|
operates.
|
|
|
|
|
|
|
|
|
|
`--help'
|
|
|
|
|
`-h'
|
|
|
|
|
Print a summary of all of the options to `configure', and exit.
|
|
|
|
|
|
|
|
|
|
`--help=short'
|
|
|
|
|
`--help=recursive'
|
|
|
|
|
Print a summary of the options unique to this package's
|
|
|
|
|
`configure', and exit. The `short' variant lists options used
|
|
|
|
|
only in the top level, while the `recursive' variant lists options
|
|
|
|
|
also present in any nested packages.
|
|
|
|
|
|
|
|
|
|
`--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.
|
|
|
|
|
|
|
|
|
|
`--prefix=DIR'
|
|
|
|
|
Use DIR as the installation prefix. *Note Installation Names::
|
|
|
|
|
for more details, including other options available for fine-tuning
|
|
|
|
|
the installation locations.
|
|
|
|
|
|
|
|
|
|
`--no-create'
|
|
|
|
|
`-n'
|
|
|
|
|
Run the configure checks, but stop before creating any output
|
|
|
|
|
files.
|
|
|
|
|
|
|
|
|
|
`configure' also accepts some other, not widely useful, options. Run
|
|
|
|
|
`configure --help' for more details.
|
|
|
