I can put fragment 1 in configure.in to get "#define COLOR_SUPPORT 1" or
"#define COLOR_SUPPORT 0" into config.h. However, I'd much rather have
"#define COLOR_SUPPORT" or no #define to decide if color will be
supported. To me, fragment 2 looks like it would do the trick, however
COLOR_SUPPORT will always be defined in some way. I can't remove the
define from acconfig.h or else autoheader will complain and COLOR_SUPPORT
won't be defined even if I want it so. I've seen this sort of thing done
properly in other programs, but I can't figure out how to get it to work
here.
--(fragment 1)--
AC_ARG_ENABLE(color,
[ --disable-color no color],
[case "${enableval}" in
yes) color=1 ;;
no) color=0 ;;
*) AC_MSG_ERROR(bad value ${enableval} for --disable-color) ;;
esac],
[color=1])
AC_DEFINE_UNQUOTED(COLOR_SUPPORT, ${color})
--(fragment 2)--
AC_ARG_ENABLE(color,
[ --disable-color no color],
[if test "${enableval}" = "no" ; then
AC_DEFINE(COLOR_SUPPORT)
fi
