* README.git: Document the changes. * bootstrap.conf: Set GNULIB_REVISION to avoid random updates. * configure.ac: Set the minimum autoconf version back to 2.69: that's the most common version deployed today, and it still works. * bootstrap: Copy the latest from gnulib. * autogen.sh: Ditto. * autopull.sh: Ditto. * bootstrap-funclib.sh: Ditto.

# Originally written by Paul Eggert. The canonical version of this

|
# script is maintained as top/autopull.sh in gnulib. However, to be
|
|
# useful to your package, you should place a copy of it under version
|
|
# control in the top-level directory of your package. The intent is
|
|
# that all customization can be done with a bootstrap.conf file also
|
|
# maintained in your version control; gnulib comes with a template
|
|
# build-aux/bootstrap.conf to get you started.
|
|
#
|
|
# Alternatively, you can use an autopull.sh script that is specific
|
|
# to your package.

Bootstrap this package from the checked-out sources.
|
|
|
|
Optional environment variables:
|
|
GNULIB_SRCDIR Specifies the local directory where gnulib
|
|
sources reside. Use this if you already
|
|
have gnulib sources on your machine, and
|
|
you want to use these sources.
|
|
GNULIB_REFDIR Specifies the local directory where a gnulib
|
|
repository (with a .git subdirectory) resides.
|
|
Use this if you already have gnulib sources
|
|
and history on your machine, and do not want
|
|
to waste your bandwidth downloading them again.
|
|
GNULIB_URL Cloneable URL of the gnulib repository.
|
|
|
|
Options:
|
|
--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
|
|
--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 or the --gnulib-srcdir option
|
|
points to a gnulib repository with the correct
|
|
revision
|
|
--skip-po do not download po files
|
|
EOF

|
bootstrap_print_option_usage_hook
|
|
cat <<EOF
|
|
If the file bootstrap.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 the environment variable GNULIB_SRCDIR is set (either as an
|
|
environment variable or via the --gnulib-srcdir option), then sources
|
|
are fetched from that local directory. If it is a git repository and
|
|
the configuration variable GNULIB_REVISION is set in bootstrap.conf,
|
|
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. If GNULIB_REFDIR is set (either
|
|
as an environment variable or via the --gnulib-refdir option) and is
|
|
a git repository, then it is used as a reference.
|
|
|
|
* 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 the configuration variable GNULIB_REVISION is set in bootstrap.conf,
|
|
then that revision is checked out.
|
|
|
|
* Otherwise, the existing Gnulib sources in the 'gnulib' directory are
|
|
used. If it is a git repository and the configuration variable
|
|
GNULIB_REVISION is set in bootstrap.conf, 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 bootstrap.conf.
|
|
|
|
Running without arguments will suffice in most cases.
