DPATCH.MAKE(7) dpatch DPATCH.MAKE(7)
NAME
dpatch.make - simplistic wrapper around dpatch(1) for make(1).
SYNOPSIS
include /usr/share/dpatch/dpatch.make
DESCRIPTION
For backwards compatibility and ease of use, dpatch.make is provided along with dpatch(1). Its purpose is to implement generic patch and
unpatch rules that can be reused in debian/rules scripts.
WARNING
dpatch is deprecated, please switch to the `3.0 (quilt)' Debian source package format instead. See http://wiki.debian.org/Projects/Deb-
Src3.0#FAQ for a short guide on how to do it.
USAGE
Using dpatch.make is rather straightforward: one has to include the file in debian/rules, change the appropriate targets to depend on patch
and unpatch, and that is all it takes.
Figuring out what the appropriate target is, requires some thought. Generally, one has a build target, or config.status, or configure (or
any of these with a -stamp suffix). Most of the time these are called first during the build, so one of these (the one that exists, and is
not depended upon by another one) has to be modified to depend on the patch target in dpatch.make.
Doing the same for the clean target is easier. One only has to rename the old rule to, say, clean-patched, then make a new one that has
clean-patched and unpatch in its list of prerequisites.
CUSTOMISATION
There are a few variables which are used by dpatch.make, which can be set before including it, in order to change the systems behaviour a
little.
These variables are:
DEB_SOURCE_PACKAGE
This is the name of the source package, used when creating the stamp file. By default, it is empty.
DPATCH_STAMPDIR
This is the directory where stamp files will be put. Default is debian/patched.
DPATCH_STAMPFN
The name of the stamp file, which contains the patch descriptions and other possible meta-data. Default value is patch-stamp.
DPATCH_PREDEPS
A list of make targets to call before applying the dpatch.
DPATCH_WORKDIR
The target directory to apply patches to. By default, it is the current directory.
PATCHLIST
The list of patches to apply. This is an alternative to debian/patches/00list - that is, if this variable is not empty, the
contents of 00list will be ignored, and this variable will be used instead.
EXAMPLE
include /usr/share/dpatch/dpatch.make
build: build-stamp
build-stamp: patch-stamp
${MAKE}
touch build-stamp
clean: clean1 unpatch
clean1:
${MAKE} clean
rm -rf debian/files debian/substvars debian/imaginary-package
.PHONY: patch unpatch ...
.
.
.
SIDE EFFECTS
Using dpatch.make instead of calling dpatch directly has one side effect: it will create a file called patch-stamp containing some
meta-information extracted from the scriptlets.
Depending on a phony patch target directly from build target may cause build target to be reevaluated even when there is no change to be
done. Instead, try making build-stamp depend on patch-stamp as specified in this example.
