1085 dnl This macro figures out how to build C programs using POSIX
1086 dnl threads. It sets the PTHREAD_LIBS output variable to the threads
1087 dnl library and linker flags, and the PTHREAD_CFLAGS output variable
1088 dnl to any special C compiler flags that are needed. (The user can also
1089 dnl force certain compiler flags/libs to be tested by setting these
1090 dnl environment variables.)
1091 dnl
1092 dnl Also sets PTHREAD_CC to any special C compiler that is needed for
1093 dnl multi-threaded programs (defaults to the value of CC otherwise).
1094 dnl (This is necessary on AIX to use the special cc_r compiler alias.)
1095 dnl
1096 dnl If you are only building threads programs, you may wish to
1097 dnl use these variables in your default LIBS, CFLAGS, and CC:
1098 dnl
1099 dnl LIBS="$PTHREAD_LIBS $LIBS"
1100 dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
1101 dnl CC="$PTHREAD_CC"
1102 dnl
1103 dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
1104 dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE
1105 dnl to that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
1106 dnl
1107 dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
1108 dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands
1109 dnl to run it if it is not found. If ACTION-IF-FOUND is not specified,
1110 dnl the default action will define HAVE_PTHREAD.
1111 dnl
1112 dnl Please let the authors know if this macro fails on any platform,
1113 dnl or if you have any other suggestions or comments. This macro was
1114 dnl based on work by SGJ on autoconf scripts for FFTW (www.fftw.org)
1115 dnl (with help from M. Frigo), as well as ac_pthread and hb_pthread
1116 dnl macros posted by AFC to the autoconf macro repository. We are also
1117 dnl grateful for the helpful feedback of numerous users.
