| 83 | Gnulib sources can be fetched in various ways:
|
|---|
| 84 |
|
|---|
| 85 | * If this package is in a git repository with a 'gnulib' submodule
|
|---|
| 86 | configured, then that submodule is initialized and updated and sources
|
|---|
| 87 | are fetched from there. If \$GNULIB_SRCDIR is set (directly or via
|
|---|
| 88 | --gnulib-srcdir) and is a git repository, then it is used as a reference.
|
|---|
| 89 |
|
|---|
| 90 | * Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir),
|
|---|
| 91 | then sources are fetched from that local directory. If it is a git
|
|---|
| 92 | repository and \$GNULIB_REVISION is set, then that revision is checked
|
|---|
| 93 | out.
|
|---|
| 94 |
|
|---|
| 95 | * Otherwise, if this package is in a git repository with a 'gnulib'
|
|---|
| 96 | submodule configured, then that submodule is initialized and updated and
|
|---|
| 97 | sources are fetched from there.
|
|---|
| 98 |
|
|---|
| 99 | * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are
|
|---|
| 100 | cloned into that directory using git from \$GNULIB_URL, defaulting to
|
|---|
| 101 | $default_gnulib_url.
|
|---|
| 102 | If \$GNULIB_REVISION is set, then that revision is checked out.
|
|---|
| 103 |
|
|---|
| 104 | * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
|
|---|
| 105 | used. If it is a git repository and \$GNULIB_REVISION is set, then that
|
|---|
| 106 | revision is checked out.
|
|---|
| 107 |
|
|---|
| 108 | If you maintain a package and want to pin a particular revision of the
|
|---|
| 109 | Gnulib sources that has been tested with your package, then there are two
|
|---|
| 110 | possible approaches: either configure a 'gnulib' submodule with the
|
|---|
| 111 | appropriate revision, or set \$GNULIB_REVISION (and if necessary
|
|---|
| 112 | \$GNULIB_URL) in $me.conf.
|
|---|
| 113 |
|
|---|
| 114 | Running without arguments will suffice in most cases.
