# CXXFLAGS and LIBS for avifile
# taken from Autostar Sandbox, http://autostars.sourceforge.net/
# constructed by careful cross-pollination from various sources and lots of
# hard labour
dnl Usage:
dnl AM_PATH_AVIFILE(MINIMUM-VERSION, [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
dnl Test for avifile, and defines
dnl - AVIFILE_CXXFLAGS (C++ compiler flags)
dnl - AVIFILE_LDFLAGS (linker flags, stripping and path)
dnl as well as set HAVE_AVIFILE to yes or no
dnl
dnl FIXME: should define AVIFILE_VERSION
dnl
dnl prerequisites:
dnl - working C++ compiler
dnl - usable libstdc++
dnl - AC_PATH_XTRA
AC_DEFUN([AM_PATH_AVIFILE],
[
AC_REQUIRE([AC_PROG_CXX])
AC_REQUIRE([AC_PATH_XTRA])
HAVE_AVIFILE=no
dnl first look for avifile-config
AC_PATH_PROG(AVIFILE_CONFIG, avifile-config, no)
min_avifile_version=ifelse([$1], ,0.7.0, $1)
if test "x$AVIFILE_CONFIG" != "xno"; then
dnl now that we have it, we need to save libs and cflags
AVIFILE_LDFLAGS=`avifile-config --libs`
AVIFILE_CXXFLAGS=`avifile-config --cflags`
AC_SUBST(AVIFILE_LDFLAGS)
AC_SUBST(AVIFILE_CXXFLAGS)
HAVE_AVIFILE=yes
fi
dnl we got this far, now start checking if we have the right version
if test x$HAVE_AVIFILE = xyes ; then
AC_MSG_CHECKING(for avifile - version >= $min_avifile_version)
dnl first get the version number from avifile-config
avifile_major_version=`$AVIFILE_CONFIG $avifile_args --version | \
sed 's/\([[0-9]]*\).\([[0-9]]*\).\([[0-9]]*\)/\1/'`
avifile_minor_version=`$AVIFILE_CONFIG $avifile_args --version | \
sed 's/\([[0-9]]*\).\([[0-9]]*\).\([[0-9]]*\)/\2/'`
avifile_micro_version=`$AVIFILE_CONFIG $avifile_config_args --version | \
sed 's/\([[0-9]]*\).\([[0-9]]*\).\([[0-9]]*\)/\3/'`
dnl now run a short C app that tells us if the version is ok or not
dnl all of this is boilerplate code from other examples
