1081 dnl This macro figures out how to build C programs using POSIX
1082 dnl threads. It sets the PTHREAD_LIBS output variable to the threads
1083 dnl library and linker flags, and the PTHREAD_CFLAGS output variable
1084 dnl to any special C compiler flags that are needed. (The user can also
1085 dnl force certain compiler flags/libs to be tested by setting these
1086 dnl environment variables.)
1087 dnl
1088 dnl Also sets PTHREAD_CC to any special C compiler that is needed for
1089 dnl multi-threaded programs (defaults to the value of CC otherwise).
1090 dnl (This is necessary on AIX to use the special cc_r compiler alias.)
1091 dnl
1092 dnl If you are only building threads programs, you may wish to
1093 dnl use these variables in your default LIBS, CFLAGS, and CC:
1094 dnl
1095 dnl LIBS="$PTHREAD_LIBS $LIBS"
1096 dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
1097 dnl CC="$PTHREAD_CC"
1098 dnl
1099 dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
1100 dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE
1101 dnl to that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
1102 dnl
1103 dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
1104 dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands
1105 dnl to run it if it is not found. If ACTION-IF-FOUND is not specified,
1106 dnl the default action will define HAVE_PTHREAD.
1107 dnl
1108 dnl Please let the authors know if this macro fails on any platform,
1109 dnl or if you have any other suggestions or comments. This macro was
1110 dnl based on work by SGJ on autoconf scripts for FFTW (www.fftw.org)
1111 dnl (with help from M. Frigo), as well as ac_pthread and hb_pthread
1112 dnl macros posted by AFC to the autoconf macro repository. We are also
1113 dnl grateful for the helpful feedback of numerous users.
