# SYNOPSIS
|
|
#
|
|
# ACX_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.

#
|
|
# Check for an OpenGL implementation. If GL is found, the required

|
# compiler and linker flags are included in the output variables

# "GL_CFLAGS" and "GL_LIBS", respectively. This macro adds the

# configure option "--with-apple-opengl-framework", which users can

|
# use to indicate that Apple's OpenGL framework should be used on Mac
|
|
# OS X. If Apple's OpenGL framework is used, the symbol
|
|
# "HAVE_APPLE_OPENGL_FRAMEWORK" is defined. If no GL implementation
|
|
# is found, "no_gl" is set to "yes".

# DESCRIPTION
|
|
#
|
|
# This macro searches for a GNU version of make. If a match is found,

|
#
|
|
# Here is an example of its use:

# Then configure.in would normally contain:
|
|
#
|
|
# CHECK_GNU_MAKE()
|
|
# AC_OUTPUT(Makefile)
|
|
#
|
|
# Then perhaps to cause gnu make to override any other make, we could
|
|
# do something like this (note that GNU make always looks for
|
|
# GNUmakefile first):
|
|
#
|
|
# if ! test x$_cv_gnu_make_command = x ; then
|
|
# mv Makefile GNUmakefile
|
|
# echo .DEFAULT: > Makefile ;
|
|
# echo \ $_cv_gnu_make_command \$@ >> Makefile;
|
|
# fi
|
|
#
|
|
# Then, if any (well almost any) other make is called, and GNU make
|
|
# also exists, then the other make wraps the GNU make.
