# CFLAGS and library paths for LIBLAME
# taken from Autostar Sandbox, http://autostars.sourceforge.net/
# inspired by xmms.m4
dnl Usage:
dnl AM_PATH_LIBLAME([MINIMUM-VERSION, [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
dnl FIXME: version checking does not work currently
dnl
dnl Example:
dnl AM_PATH_LIBLAME(3.89, , AC_MSG_ERROR([*** LIBLAME >= 3.89 not installed))
dnl
dnl Defines LIBLAME_LIBS
dnl FIXME: should define LIBLAME_VERSION
dnl
AC_DEFUN(AM_PATH_LIBLAME,
[
dnl check for the library
AC_CHECK_LIB(mp3lame, lame_init, HAVE_LIBLAME=yes, HAVE_LIBLAME=no, -lm)
dnl check if lame.h is available in the standard location or not
HAVE_LAME_H_STD=no
AC_CHECK_HEADER(lame.h, HAVE_LAME_H_STD=no, :)
AC_CHECK_HEADER(lame/lame.h, HAVE_LAME_H_STD=yes, :)
AC_MSG_CHECKING(for lame.h in right location)
if test "x$HAVE_LAME_H_STD" = "xyes"; then
AC_MSG_RESULT(yes)
else
AC_MSG_RESULT(no)
HAVE_LIBLAME=no

AC_MSG_WARN(lame.h found in include dir,)
AC_MSG_WARN( while it should be in it's own lame/ dir !)

dnl now do the actual "do we have it ?" test

dnl execute what we have to because it's not found
ifelse([$3], , :, [$3])
