package.bbclass: Support stripping and debug copy of static libraries
By default, we won't copy and strip static libraries. However, this
functionality can be useful in some cases where people are doing
development on the target, and don't generally want the larger debug
capable static libraries. To enable the new functionality set:
PACKAGE_DEBUG_STATIC_SPLIT = '1'
Add a new function splitstaticdebuginfo. Thus function will copy the
unmodified static library into the specific debug directory location.
By keeping an unmodified version, it is possible for a user trying
to debug something to use -L /usr/lib/.debug-static and their existing
build commands to switch from stripped to full debug versions.
The PACKAGE_DEBUG_SPLIT_STYLE will select between two different
approaches, /usr/lib/debug-static or <path>/.debug-static.
Additionally you can now choose to strip static libraries to conserve
space. If either 'PACKAGE_DEBUG_STATIC_SPLIT' or 'PACKAGE_STRIP_STATIC'
is set to 1, the static library will be stripped. (This is not on by
default, as it could make diagnosing static library usage difficult in
some cases.)
Add to insane.bbclass a skip to the staticdev warning for the specific
-dbg package versions.
