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. # Please report bugs or propose patches to bug-gnulib@gnu.org. scriptversion=2022-07-29.23; # UTC me="$0" medir=`dirname "$me"` # Read the function library and the configuration. . "$medir"/bootstrap-funclib.sh usage() { cat <<EOF Usage: $me [OPTION]... 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 do not want to waste your bandwidth downloading them again. GNULIB_URL Cloneable URL of the gnulib repository. Options: --gnulib-srcdir=DIRNAME specify 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. Defaults to \$GNULIB_SRCDIR --gnulib-refdir=DIRNAME specify 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. Defaults to \$GNULIB_REFDIR --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 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.
