582+dnl
583+dnl This macro figures out how to build C programs using POSIX threads.
584+dnl It sets the PTHREAD_LIBS output variable to the threads library and
585+dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
586+dnl C compiler flags that are needed. (The user can also force certain
587+dnl compiler flags/libs to be tested by setting these environment
588+dnl variables.)
589+dnl
590+dnl Also sets PTHREAD_CC to any special C compiler that is needed for
591+dnl multi-threaded programs (defaults to the value of CC otherwise).
592+dnl (This is necessary on AIX to use the special cc_r compiler alias.)
593+dnl
594+dnl NOTE: You are assumed to not only compile your program with these
595+dnl flags, but also link it with them as well. e.g. you should link
596+dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
597+dnl $LIBS
598+dnl
599+dnl If you are only building threads programs, you may wish to use
600+dnl these variables in your default LIBS, CFLAGS, and CC:
601+dnl
602+dnl LIBS="$PTHREAD_LIBS $LIBS"
603+dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
604+dnl CC="$PTHREAD_CC"
605+dnl
606+dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
607+dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
608+dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
609+dnl
610+dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
611+dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
612+dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
613+dnl default action will define HAVE_PTHREAD.
614+dnl
615+dnl Please let the authors know if this macro fails on any platform, or
616+dnl if you have any other suggestions or comments. This macro was based
617+dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
618+dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
619+dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
620+dnl We are also grateful for the helpful feedback of numerous users.
