# ======================================================================

# By default we build for Ubuntu (I'm testing on Ubuntu 8.04).
#
# If you want to build for another distro, see if it's listed in the DISTROS
# variable (currently only Debian & Ubuntu releases are listed) and, if so,
# change "DISTRO" to your distro.  You can do this in local.mk to avoid
# changing this makefile.
#
# If your distro is not supported, you can set "distro" to empty and the check
# for prerequisite packages will be skipped.  Of course, if you don't have all
# the proper development packages installed the build will fail.

# What branch to work with.  If not set, we use the trunk.  Close to a
# release, however, you might prefer to use the pending release.
# E.g.:
#   BRANCH := 2.20
BRANCH :=

# Where to install Evo.  DO NOT use /usr here for any system controlled by a
# package manager (rpm, dpkg)
PREFIX :=	/opt/evo

# Where to build objects.  Currently not all packages work properly outside of
# their own directories, even though the GNU coding standards require it.
OBJDIR :=	obj
#OBJDIR :=	.

# What distro you use, for checking that all prerequisite packages for a
# successful build are installed.  The currently supported distros are
# listed in the DISTROS variable below.
# If yours is not one of these, set this to empty and take your chances!

CCACHE :=	ccache

# Set this to empty if you want to see the rules being run

#h:Makefile for building Evolution from SVN
#h:----------------------------------------
#h:
#h:MAKE TARGETS:
#h:
#h:all		[Default] Check out, configure, compile, install the various
#h:		components necessary to build Evolution from SVN.
#h:
#h:update		Perform SVN updates of all the checked out components.
#h:
#h:check-update	Check whether there are new updates in the SVN repository.
#h:		Doesn't check anything out.
#h:
#h:check-changelog	Check whether there are new updates, AND show the ChangeLog
#h:		diffs.
#h:
#h:check-prereqs	Verify that the packages needed for the build are installed.
#h:
#h:clean		For each source package, "make clean"
#h:
#h:shinyclean	Remove the source packages completely
#h:
#h:superclean	Remove the source packages AND the installed Evolution
#h:
#h:
#h:CUSTOMIZATION:
#h:
#h:You can create a makefile "local.mk" in the same directory that contains the
#h:Makefile.  This file, if it exists, can contain one or more of the following
#h:variables:
#h:
#h:PREFIX		The directory in which to install Evolution.
#h:		Must NOT be /usr!
#h:
#h:DISTRO		The GNU/Linux distribution you're running.  This helps the
#h:		Makefile check for the right packages before starting the
#h:		build.  Currently supported are "feisty", "gutsy", "hardy", and
#h:		"etch" (Debian).  You can also set it to empty and hope for the best.
#h:
#h:BRANCH		The SVN label or branch to build.  If you don't set this then
#h:		a distro-specific value is chosen: it uses the SVN trunk where
#h:		possible.
#h:
#h:CCACHE		Enable ccache (on by default).  If you don't want to use it,
#h:		set this to empty.
#h:
#h:ENABLE_exchange	Turn on Evolution Exchange support (on by default).  If you
#h:		don't want to build it, set this to "n" (or any non-"y"
#h:		value).
#h:
#h:ENABLE_webcal	Turn on Evolution Webcall support (on by default).  If you
#h:		don't want to build it, set this to "n" (or any non-"y"
#h:		value).
#h:
#h:LINGUAS		Restrict the number of translations built and installed to
#h:		those listed in this variable.
#h:
#h:local_PACKAGES	A list of extra packages you want to build.  These must be
#h:		"standard" Gnome packages kept on the Gnome SVN server and
#h:		using the normal build operations.  Common packages you might
#h:		want to list here are glib, libbonobo, and libsoup.
#h:
