Usage: $me [OPTION]... |
|
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. |
