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 and PTHREAD_CXX to any special C compiler that is ++# needed for multi-threaded programs (defaults to the value of CC ++# respectively CXX otherwise). (This is necessary on e.g. AIX to use the ++# special cc_r/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 ++# $PTHREAD_CXX $CXXFLAGS $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 $PTHREAD_CFLAGS" ++# CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS" ++# CC="$PTHREAD_CC" ++# CXX="$PTHREAD_CXX" ++# ++# 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.
