# 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 to link with them as well. For example, you might link with
|
|
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
|
|
#
|
|
# If you are only building threaded programs, you may wish to use these
|
|
# variables in your default LIBS, CFLAGS, and CC:
|
|
#
|
|
# LIBS="$PTHREAD_LIBS $LIBS"
|
|
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
|
|
# CC="$PTHREAD_CC"
|
|
#
|
|
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
|
|
# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
|
|
# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
|
|
#
|
|
# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
|
|
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
|
|
# PTHREAD_CFLAGS.
|
|
#
|
|
# 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.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
|
|
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
|
|
#
|
|
# Of course, Automake must honor this variable whenever it calls a
|
|
# tool from the auxiliary directory. The problem is that $srcdir (and
|
|
# therefore $ac_aux_dir as well) can be either absolute or relative,
|
|
# depending on how configure is run. This is pretty annoying, since
|
|
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
|
|
# source directory, any form will work fine, but in subdirectories a
|
|
# relative path needs to be adjusted first.
|
|
#
|
|
# $ac_aux_dir/missing
|
|
# fails when called from a subdirectory if $ac_aux_dir is relative
|
|
# $top_srcdir/$ac_aux_dir/missing
|
|
# fails if $ac_aux_dir is absolute,
|
|
# fails when called from a subdirectory in a VPATH build with
|
|
# a relative $ac_aux_dir
|
|
#
|
|
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
|
|
# are both prefixed by $srcdir. In an in-source build this is usually
|
|
# harmless because $srcdir is '.', but things will broke when you
|
|
# start a VPATH build or use an absolute $srcdir.
|
|
#
|
|
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
|
|
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
|
|
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
|
|
# and then we would define $MISSING as
|
|
# MISSING="\${SHELL} $am_aux_dir/missing"
|
|
# This will work as long as MISSING is not called from configure, because
|
|
# unfortunately $(top_srcdir) has no meaning in configure.
|
|
# However there are other variables, like CC, which are often used in
|
|
# configure, and could therefore not use this "fixed" $ac_aux_dir.
|
|
#
|
|
# Another solution, used here, is to always expand $ac_aux_dir to an
|
|
# absolute PATH. The drawback is that using absolute paths prevent a
|
|
# configured tree to be moved without reconfiguration.
