Extract API/source/raw archives from the Genode source tree
|
|
|
|
usage:
|
|
|
|
$(firstword $(MAKEFILE_LIST)) <archive-path>...
|
|
|
|
The <archive-path> argument denotes the archive to extract in the
|
|
form of a path. The first path element correponds to the identity
|
|
of the archive creator, the second element corresponds to the type
|
|
of the archive, and the third element refers to the recipe of
|
|
the archive description.
|
|
|
|
E.g., the user 'alan' may create the following archives:
|
|
|
|
alan/api/libc - an API archive for the libc
|
|
alan/src/zlib - a source archive for the zlib library
|
|
|
|
The following arguments tweak the operation of the tool:
|
|
|
|
FORCE=1 Replace existing archives with freshly created
|
|
ones. This is useful during the development of
|
|
recipes.
|
|
|
|
VERBOSE= Show individual operations.
|
|
|
|
-j<N> Enable the parallel creation of packages where
|
|
<N> denotes the level of parallelism.
|
|
|
|
UPDATE_VERSIONS=1 Automatically increase the version of recipe
|
|
hash files whenever their respective archive
|
|
content has changed. The versions are named
|
|
after the output of the VERSION_CMD, suffixed
|
|
with a single letter in case VERSION_CMD would
|
|
return the same version the archive already
|
|
has.
|
|
|
|
VERSION_CMD= The script whose output is used in case the
|
|
archive version needs to be updated. The default
|
|
is to use the current date.
