# Automagical conversion of autoreconf results into quilt patches.
# Copyright 2006 Eugene Konev
#
# Licensed under the GNU General Public License, version 2. See the file
# /usr/share/common-licenses/GPL or <http://www.gnu.org/copyleft/gpl.txt>.
# The idea behind this is storing changes produced by autoreconf as a
# separate patch on quilt stack (on top of stack actually).
# The only usable target here is 'autoreconf`. Other targets are not
# supposed to be called directly. DO NOT invoke them, unless you know what
# you are doing.
# The autoreconf target will check if files with names in $(RECONF_CHECKFILES)
# were changed during patching (from upstream version or from previously
# autoreconfed version) and call actual autoreconfing if they were.
# The actual autoreconfing target (doautoreconf) WILL FAIL after
# calling autoreconf and pushing changes into quilt stack by design. It
# should never be invoked by automatic build process.
# The proposed use is adding autoreconf into clean's prerequisites before
# xsfclean like:
# - clean: xsfclean
# + clean: autoreconf xsfclean
# This will ensure it is called when you build package with dpkg-buildpackage.
# This dir will be used for producing diff of autoreconfed tree
RECONF_DIR := xsfautoreconf
# This files will be checked for changes
RECONF_CHECKFILES += configure.ac Makefile.am
# This files will not be hardlinked but copied
RECONF_NOLINKFILES += aclocal.m4
# This files/dirs will be pruned after autoreconf run
RECONF_PRUNEFILES += autom4te.cache config.h.in~ aclocal.m4~
