Upgrade Gnulib files to 20190105. It's much easier to maintain GRUB's use of portability support files from Gnulib when the process is automatic and driven by a single configuration file, rather than by maintainers occasionally running gnulib-tool and committing the result. Removing these automatically-copied files from revision control also removes the temptation to hack the output in ways that are difficult for future maintainers to follow. Gnulib includes a "bootstrap" program which is designed for this. The canonical way to bootstrap GRUB from revision control is now "./bootstrap", but "./autogen.sh" is still useful if you just want to generate the GRUB-specific parts of the build system. GRUB now requires Autoconf >= 2.63 and Automake >= 1.11, in line with Gnulib. Gnulib source code is now placed in grub-core/lib/gnulib/ (which should not be edited directly), and GRUB's patches are in grub-core/lib/gnulib-patches/. I've added a few notes to the developer manual on how to maintain this. Signed-off-by: Colin Watson <cjwatson@ubuntu.com> Reviewed-by: Daniel Kiper <daniel.kiper@oracle.com>

Bootstrap this package from the checked-out sources.
|
|
|
|
Options:
|
|
--gnulib-srcdir=DIRNAME specify the local directory where gnulib
|
|
sources reside. Use this if you already
|
|
have gnulib sources on your machine, and
|
|
do not want to waste your bandwidth downloading
|
|
them again. Defaults to \$GNULIB_SRCDIR
|
|
--bootstrap-sync if this bootstrap script is not identical to
|
|
the version in the local gnulib sources,
|
|
update this script, and then restart it with
|
|
/bin/sh or the shell \$CONFIG_SHELL
|
|
--no-bootstrap-sync do not check whether bootstrap is out of sync
|
|
--copy copy files instead of creating symbolic links
|
|
--force attempt to bootstrap even if the sources seem
|
|
not to have been checked out
|
|
--no-git do not use git to update gnulib. Requires that
|
|
--gnulib-srcdir point to a correct gnulib snapshot
|
|
--skip-po do not download po files
|
|
|
|
If the file $me.conf exists in the same directory as this script, its
|
|
contents are read as shell variables to configure the bootstrap.
|
|
|
|
For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
|
|
are honored.
|
|
|
|
Gnulib sources can be fetched in various ways:
|
|
|
|
* If this package is in a git repository with a 'gnulib' submodule
|
|
configured, then that submodule is initialized and updated and sources
|
|
are fetched from there. If \$GNULIB_SRCDIR is set (directly or via
|
|
--gnulib-srcdir) and is a git repository, then it is used as a reference.
|
|
|
|
* Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir),
|
|
then sources are fetched from that local directory. If it is a git
|
|
repository and \$GNULIB_REVISION is set, then that revision is checked
|
|
out.
|
|
|
|
* Otherwise, if this package is in a git repository with a 'gnulib'
|
|
submodule configured, then that submodule is initialized and updated and
|
|
sources are fetched from there.
|
|
|
|
* Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are
|
|
cloned into that directory using git from \$GNULIB_URL, defaulting to
|
|
$default_gnulib_url.
|
|
If \$GNULIB_REVISION is set, then that revision is checked out.
|
|
|
|
* Otherwise, the existing Gnulib sources in the 'gnulib' directory are
|
|
used. If it is a git repository and \$GNULIB_REVISION is set, then that
|
|
revision is checked out.
|
|
|
|
If you maintain a package and want to pin a particular revision of the
|
|
Gnulib sources that has been tested with your package, then there are two
|
|
possible approaches: either configure a 'gnulib' submodule with the
|
|
appropriate revision, or set \$GNULIB_REVISION (and if necessary
|
|
\$GNULIB_URL) in $me.conf.
|
|
|
|
Running without arguments will suffice in most cases.
