- # SYNOPSIS
- #
- # AX_SUBST_WITH([varname])
- #
- # DESCRIPTION
- #
- # a very simple macro but also very helpful - the varname is usually the
- # one from an AC_ARG_ENABLE or AC_ARG_WITH option. it is transliterated
- # into uppercase and a prefix WITH_ and WITHOUT_ that are both _SUBSTed.
- #
- # Only one of these is set to "#" while the other is empty. In other words
- # a call like AC_WITHNONE(enable-call) will create two SUBST-symbols as
- # WITH_ENABLE_CALL and WITHOUT_ENABLE_CALL. When the varname had been set
- # to something not "no" or "0" or ":" or "false" then it results in
- #
- # WITH_ENABLE_CALL="" ; WITHOUT_ENABLE_CALL="#"
- #
- # which you can use in your Makefile quite easily as if using an
- # AM_CONDITIONAL but which can be also parsed by normal make
- #
- # USE = @WITH_ENABLE_CALL@ -Denabled USE = @WITHOUT_ENABLE_CALL@
- # -Dnot_enabled
