(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.
