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

# 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. |
