These notes intend to help people working on the checked-out sources.
These requirements do not apply when building from a distribution tarball.

* Requirements

We've opted to keep only the highest-level sources in the GIT repository.
This eases our maintenance burden, (fewer merges etc.), but imposes more
requirements on anyone wishing to build from the just-checked-out sources.
For example, you have to use the latest stable versions of the maintainer
tools we depend upon, including:

- Automake <http://www.gnu.org/software/automake/>
- Autoconf <http://www.gnu.org/software/autoconf/>
- Bison <http://www.gnu.org/software/bison/>
- Gettext <http://www.gnu.org/software/gettext/>
- Gperf <http://www.gnu.org/software/gperf/>
- Gzip <http://www.gnu.org/software/gzip/>
- Perl <http://www.cpan.org/>
- Rsync <http://samba.anu.edu.au/rsync/>
- Tar <http://www.gnu.org/software/tar/>

Valgrind <http://valgrind.org/> is also highly recommended, if
Valgrind supports your architecture.

Only building the initial full source tree will be a bit painful.
Later, a plain `git pull && make' should be sufficient.

* LZMA

The coreutils build procedure can build distribution tarballs with the
LZMA compression scheme.  This feature is so new that it is not
supported by the latest version of Automake.  If you don't care about
building LZMA tarballs, you can manually remove the string "dist-lzma"
from configure.ac before bootstrapping.

If you do want to build LZMA tarballs, you'll need to make sure you
have the latest stable version of the LZMA Utils
<http://tukaani.org/lzma/>.  Also, you'll need a version of
Automake that supports the dist-lzma feature, which was added to
Automake on 2007-10-09 but is not yet available in a stable Automake
version.  So until Automake 1.11 comes out, you'll need to get the
bleeding-edge Automake version with a command like this:

	$ git clone git://git.sv.gnu.org/automake
	$ cd automake
	$ ./bootstrap
	$ ./configure
	$ make install

and build and install that version.

* First GIT checkout

You can get a copy of the source repository like this:

	$ git clone git://git.sv.gnu.org/coreutils

The next step is to get other files needed to build, which are
extracted from other source packages:

	$ ./bootstrap

And there you are!  Just

	$ ./configure
	$ make
	$ make check

At this point, there should be no difference between your local copy,
and the GIT master copy:

	$ git diff

should output no difference.

Enjoy!
