[bug-gsrc] progress report - initial version in bzr

[Brian Gough]

I have not forgotten about this project.  I've been looking at ways to
export a single gsrc tarball that allows end-users to build the
sources easily.

I've decided to use Nick Moffit's GAR (GNUmake Autobuild Runtime),
which was the system used for the old FSF Bootable CDs and is a pure
makefile, so pretty easy to use.  It handles dependencies, downloads
(with checksums/signatures) and setting different compilation options.

I've grabbed a more recent version from GARstow maintained by Adam
Sampsom (address@hidden) and used that as a starting point.

I plan to synchronise the version information with Nixpkgs-libre, to
keep it up to date.  I have a script that does that.

Since it doesn't need a top-level makefile/configure script we are
free to add our own (to handle anything like ./configure
--disable-video or whatever).

The initial version is at 

  bzr branch http://bzr.savannah.gnu.org/r/gsrc/trunk

Examples:

  make -C gnu/hello          # downloads and builds hello
  make -C gnu/hello install  # installs it under ~/gar
  make -C gnu/patch          # builds patch, after automatically building ed 
(which is a dependency)

These should work - but if anything else does, it's a fluke.

Look in gnu/ed/Makefile for a sample definition:

----------------------------------------------------------------------
GARNAME = patch
GARVERSION = 2.6.1

MASTER_SITES = $(MASTER_GNU)
MASTER_SUBDIR = patch/
DISTFILES = $(GARNAME)-$(GARVERSION).tar.gz

BUILDDEPS = ed
USE_TESTS = 1

HOME_URL = http://savannah.gnu.org/projects/patch
DESCRIPTION = GNU patch

include ../../gar.lib/auto.mk
