In particular, this incorporates Roman's patches to allow 'make syntax-check' to work on BSD with its exec argv limitations that previously failed when trying to grep the large number of files present in libvirt. cfg.mk needs similar changes, but that will be tackled separately.

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.
