|

||||
|
||||
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. |
||||
|
||||
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. |
||||
|
||||
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). |
||||
|
||||
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 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. |

# SYNOPSIS |
||||
# |
||||
# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]) |
||||
# |
||||
# DESCRIPTION |
||||
# |
||||
# This macro figures out how to build C programs using POSIX threads. It |
||||
# sets the PTHREAD_LIBS output variable to the threads library and linker |
||||
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler |
||||
# flags that are needed. (The user can also force certain compiler |
||||
# flags/libs to be tested by setting these environment variables.) |
||||
# |
||||
# Also sets PTHREAD_CC to any special C compiler that is needed for |
||||
# multi-threaded programs (defaults to the value of CC otherwise). (This |
||||
# is necessary on AIX to use the special cc_r compiler alias.) |
||||
# |
||||
# NOTE: You are assumed to not only compile your program with these flags, |
||||
# but also link it with them as well. e.g. you should link with |
||||
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS |
||||
# |
||||
# If you are only building threads programs, you may wish to use these |
||||
# variables in your default LIBS, CFLAGS, and CC: |
||||
# |
||||
# LIBS="$PTHREAD_LIBS $LIBS" |
||||
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" |
||||
# CC="$PTHREAD_CC" |
||||
# |
||||
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant |
||||
# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name |
||||
# (e.g. PTHREAD_CREATE_UNDETACHED on AIX). |
||||
# |
||||
# ACTION-IF-FOUND is a list of shell commands to run if a threads library |
||||
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it |
||||
# is not found. If ACTION-IF-FOUND is not specified, the default action |
||||
# will define HAVE_PTHREAD. |
||||
# |
||||
# Please let the authors know if this macro fails on any platform, or if |
||||
# you have any other suggestions or comments. This macro was based on work |
||||
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help |
||||
# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by |
||||
# Alejandro Forero Cuervo to the autoconf macro repository. We are also |
||||
# grateful for the helpful feedback of numerous users. |

# These exist entirely to fool aclocal when bootstrapping libtool. |
||||
# |
||||
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN) |
||||
# which have later been changed to m4_define as they aren't part of the |
||||
# exported API, or moved to Autoconf or Automake where they belong. |
||||
# |
||||
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN |
||||
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us |
||||
# using a macro with the same name in our local m4/libtool.m4 it'll |
||||
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define |
||||
# and doesn't know about Autoconf macros at all.) |
||||
# |
||||
# So we provide this file, which has a silly filename so it's always |
||||
# included after everything else. This provides aclocal with the |
||||
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything |
||||
# because those macros already exist, or will be overwritten later. |
||||
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. |
||||
# |
||||
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here. |
||||
# Yes, that means every name once taken will need to remain here until |
||||
# we give up compatibility with versions before 1.7, at which point |
||||
# we need to keep only those names which we still refer to. |
