Here's a patch to make dh_strip use build-id if compat is >=9. Please
note that this requires relatively new binutils to work as expected,
but that shouldn't be a big deal, since it'll just fall back to the
old path-based schema if build-id cannot be extracted.
Motivation is needing to support multiarch, I see..
http://lists.debian.org/debian-devel/2011/09/msg00375.html
upstream reference: http://fedoraproject.org/wiki/RolandMcGrath/BuildID
I don't understand the symlinks mentioned there:
/usr/lib/debug/.build-id/ab/cdef1234 -> ../../../../bin/foo
/usr/lib/debug/.build-id/ab/cdef1234.debug -> ../../usr/bin/foo.debug
Perhaps for backwards compatability to the old gdb,
The other advantage of such schema is that you know which files have
debugging information just by looking at package contents.
although I don't know why the link to the binary would be needed.
This does not make sense to me either.
it seems we would not want to use these symlinks.
Agreed:
- gdb in stable already supports loading stuff from build-id
directories.
- Using the symlinks would defeat the purpose of helping
to multi-archify -dbg packages.
- If people complained that filenames in -dbg packages are not
transparent enough, a script that would print mapping between binaries
and their .debug counterparts could be easily written, to be included in
devscripts.
