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.
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/grep
$ cd grep
As an optional step, if you already have a copy of the gnulib git
repository on your hard drive, 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.
