- dnl Manually inserted M4 code for building with OpenGL (and dependencies)
- dnl which is provieded by the autoconf-archive package for many platforms,
- dnl but does not seem to be available in MacPorts for OS X.
- dnl Thanks to authors Braden McDaniel and Steven Johnson. - RTV 2008.02.24

dnl locally-defined macros go here
- ##### http://autoconf-archive.cryp.to/acx_pthread.html
- #
- # SYNOPSIS
- #
- # ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
- #
- # DESCRIPTION
- #
- # This macro figures out how to build C programs using POSIX threads.
- # It sets the PTHREAD_LIBS output variable to the threads library and
- # linker flags, and the PTHREAD_CFLAGS output variable to any special
- # C compiler flags that are needed. (The user can also force certain
- # compiler flags/libs to be tested by setting these environment
- # variables.)
- #
- # Also sets PTHREAD_CC to any special C compiler that is needed for
- # multi-threaded programs (defaults to the value of CC otherwise).
- # (This is necessary on AIX to use the special cc_r compiler alias.)
- #
- # NOTE: You are assumed to not only compile your program with these
- # flags, but also link it with them as well. e.g. you should link
- # with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
- # $LIBS
- #
- # If you are only building threads programs, you may wish to use
- # these variables in your default LIBS, CFLAGS, and CC:
- #
- # LIBS="$PTHREAD_LIBS $LIBS"
- # CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
- # CC="$PTHREAD_CC"
- #
- # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
- # constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
- # that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
- #
- # ACTION-IF-FOUND is a list of shell commands to run if a threads
- # library is found, and ACTION-IF-NOT-FOUND is a list of commands to
- # run it if it is not found. If ACTION-IF-FOUND is not specified, the
- # default action will define HAVE_PTHREAD.
- #
- # Please let the authors know if this macro fails on any platform, or
- # if you have any other suggestions or comments. This macro was based
- # on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/)
- # (with help from M. Frigo), as well as ac_pthread and hb_pthread
- # macros posted by Alejandro Forero Cuervo to the autoconf macro
- # repository. We are also grateful for the helpful feedback of
- # numerous users.
