Hi all,
I've been working on a patch to add optional dependencies for GTK+ and
GNOME to ports. Below is a first cut of bsd.optional.mk. The way that
this is used is e.g.:
.include <bsd.optional.mk>
pre-configure: msg-option-gtk
.if defined(HAVE_GTK) && ${HAVE_GTK} != "no"
USE_GTK= yes
.endif
This could be in bsd.port.pre.mk, but it might need to be before an
optional setting of USE_X_PREFIX, which must be set before then. Other
alternatives are to have an "option.mk" in /usr/ports/x11/gnome (for
example) and include that, although ${PORTSDIR} is not defined until
bsd.port{.pre|.post|}.mk is included.
Notice the fairly strict definintions of WITH_*, HAVE_* and USE_*, which
I would like to apply to all ports with optional depends.
Regards,
-Jeremy

# Please view me with 4 column tabs!
# This file keeps tests for optional software. To use these, include this
# file where you would normally include <bsd.port.pre.mk>, and after that
# file if you need to use it. This works with three sets of variables,
# WITH_, HAVE_ and USE_. WITH_ variables are used to determine if a package
# is wanted, HAVE_ variables determine what is or will be installed.
# A port should never set any WITH_ variables in it's Makefile. This file
# does not set any USE_ variables, these must be set explictly
# based on the results of this file. Other than the setting of HAVE_
# variables the only side effect of this file is to define a some message
# targets which inform the user that the port has optional dependancies.
# These targets must also be called explictly from the port's Makefile.
# The following defines are for the various levels of libraries in the
# GLib/GTK+/GNOME group of software. There are the following options:
#
# WITH_GLIB, WITH_GTK, WITH_IMLIB, WITH_GNOME:
# yes - Only set by the user, indicates that they always want
# this setting.
# no - Only set by the user, indicates that they never want
# this setting.
#
# The following variables might be set:
#
# HAVE_GLIB, HAVE_GTK:
# no - WITH_GLIB/WITH_GTK set to no.
# 10 - found GTK+ 1.0.x.
# 12 - found GLib/GTK+ 1.2.x or WITH_GLIB/WITH_GTK set to yes.
# HAVE_IMLIB:
# no - WITH_IMLIB set to no.
# yes - either found imlib or WITH_IMLIB set to yes.
# HAVE_GNOME:
# no - WITH_GNOME set to no.
# libs - found gnome-libs.
# core - found gnome-core or WITH_GNOME set to yes.
# control - found gnome-controlcenter.
