dnl @synopsis ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
|
||||
dnl
|
||||
dnl This macro figures out how to build C programs using POSIX
|
||||
dnl threads. It sets the PTHREAD_LIBS output variable to the threads
|
||||
dnl library and linker flags, and the PTHREAD_CFLAGS output variable
|
||||
dnl to any special C compiler flags that are needed. (The user can also
|
||||
dnl force certain compiler flags/libs to be tested by setting these
|
||||
dnl environment 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 $LIBS
|
||||
dnl
|
||||
dnl If you are only building threads programs, you may wish to
|
||||
dnl use these variables in your default LIBS, CFLAGS, and CC:
|
||||
dnl
|
||||
dnl LIBS="$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
|
||||
dnl to 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
|
||||
dnl to run it if it is not found. If ACTION-IF-FOUND is not specified,
|
||||
dnl the default action will define HAVE_PTHREAD.
|
||||
dnl
|
||||
dnl Please let the authors know if this macro fails on any platform,
|
||||
dnl or if you have any other suggestions or comments. This macro was
|
||||
dnl based on work by SGJ on autoconf scripts for FFTW (www.fftw.org)
|
||||
dnl (with help from M. Frigo), as well as ac_pthread and hb_pthread
|
||||
dnl macros posted by AFC to the autoconf macro repository. We are also
|
||||
dnl grateful for the helpful feedback of numerous users.
