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/DebSrc3.0#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.
