901 dnl
902 dnl This macro figures out how to build C programs using POSIX
903 dnl threads. It sets the PTHREAD_LIBS output variable to the threads
904 dnl library and linker flags, and the PTHREAD_CFLAGS output variable
905 dnl to any special C compiler flags that are needed. (The user can also
906 dnl force certain compiler flags/libs to be tested by setting these
907 dnl environment variables.)
908 dnl
909 dnl Also sets PTHREAD_CC to any special C compiler that is needed for
910 dnl multi-threaded programs (defaults to the value of CC otherwise).
911 dnl (This is necessary on AIX to use the special cc_r compiler alias.)
912 dnl
913 dnl If you are only building threads programs, you may wish to
914 dnl use these variables in your default LIBS, CFLAGS, and CC:
915 dnl
916 dnl LIBS="$PTHREAD_LIBS $LIBS"
917 dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
918 dnl CC="$PTHREAD_CC"
919 dnl
920 dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
921 dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE
922 dnl to that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
923 dnl
924 dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
925 dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands
926 dnl to run it if it is not found. If ACTION-IF-FOUND is not specified,
927 dnl the default action will define HAVE_PTHREAD.
928 dnl
929 dnl Please let the authors know if this macro fails on any platform,
930 dnl or if you have any other suggestions or comments. This macro was
931 dnl based on work by SGJ on autoconf scripts for FFTW (www.fftw.org)
932 dnl (with help from M. Frigo), as well as ac_pthread and hb_pthread
933 dnl macros posted by AFC to the autoconf macro repository. We are also
934 dnl grateful for the helpful feedback of numerous users.
