These notes intend to help people working on the checked-out sources.
These requirements do not apply when building from a distribution tarball.
See also HACKING for more detailed contribution guidelines.
* 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.
Note the requirements to build the released archive are much less and
are just the requirements of the standard ./configure && make procedure.
Specific development tools and versions will be checked for and listed by
the bootstrap script. See README-prereq for specific notes on obtaining
these prerequisite tools.
Valgrind <http://valgrind.org/> is also highly recommended, if
Valgrind supports your architecture. See also README-valgrind.
While building from a just-cloned source tree may require installing a
few prerequisites, later, a plain 'git pull && make' should be sufficient.
* First GIT checkout
You can get a copy of the source repository like this:
$ git clone git://git.sv.gnu.org/coreutils
$ cd coreutils
As an optional step, if you already have a copy of the gnulib git
repository, then you can use it as a reference to reduce download
time and disk space requirements:
$ export GNULIB_SRCDIR=/path/to/gnulib
The next step is to get and check other files needed to build,
which are extracted from other source packages:
$ ./bootstrap
To use the most-recent gnulib (as opposed to the gnulib version that
the package last synchronized to), do this next:
$ git submodule foreach git pull origin master
$ git commit -m 'build: update gnulib submodule to latest' gnulib
And there you are! Just
$ ./configure --quiet #[--enable-gcc-warnings] [*]
$ 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!
[*] The --enable-gcc-warnings option is useful only with glibc
and with a very recent version of gcc. You'll probably also have
to use recent system headers. If you configure with this option,
and spot a problem, please be sure to send the report to the bug
reporting address of this package, and not to that of gnulib, even
if the problem seems to originate in a gnulib-provided file.
* Submitting patches
If you develop a fix or a new feature, please send it to the
appropriate bug-reporting address as reported by the --help option of
each program. One way to do this is to use vc-dwim
<https://www.gnu.org/software/vc-dwim/>), as follows.
Run the command "vc-dwim --help", copy its definition of the
"git-changelog-symlink-init" function into your shell, and then run
this function at the top-level directory of the package.
Edit the (empty) ChangeLog file that this command creates, creating a
properly-formatted entry according to the GNU coding standards
<https://www.gnu.org/prep/standards/html_node/Change-Logs.html>.
Make your changes.
Run the command "vc-dwim" and make sure its output (the diff of all
your changes) looks good.
Run "vc-dwim --commit".
Run the command "git format-patch --stdout -1", and email its output
in, using the output's subject line.
