Now we have deltask API, stop poking around bitbake internal variables. (From OE-Core rev: 98637df0c04fd14b506d9eec7da8ec6ae441221b) (From OE-Core rev: 3aa30ca04752c6366a81db6ff99209fa0b46861c) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

# externalsrc.bbclass enables use of an existing source tree, usually external to
|
|
# the build system to build a piece of software rather than the usual fetch/unpack/patch
|
|
# process.
|
|
#
|
|
# To use, add externalsrc to the global inherit and set EXTERNALSRC to point at the
|
|
# directory you want to use containing the sources e.g. from local.conf for a recipe
|
|
# called "myrecipe" you would do:
|
|
#
|
|
# INHERIT += "externalsrc"
|
|
# EXTERNALSRC_pn-myrecipe = "/path/to/my/source/tree"
|
|
#
|
|
# In order to make this class work for both target and native versions (or with
|
|
# multilibs/cross or other BBCLASSEXTEND variants), B is set to point to a separate
|
|
# directory under the work directory (split source and build directories). This is
|
|
# the default, but the build directory can be set to the source directory if
|
|
# circumstances dictate by setting EXTERNALSRC_BUILD to the same value, e.g.:
|
|
#
|
|
# EXTERNALSRC_BUILD_pn-myrecipe = "/path/to/my/source/tree"
|
