The eclipse PTP project that I package is starting to ship an executable in
one of its plugins. The executable is packed into a jar file. This prevents
debuginfo creation for the executable.
I started taking a look at how this might be handled elsewhere and found:
/usr/lib64/eclipse/dropins/cdt/eclipse/plugins/org.eclipse.cdt.core.linux.x86_64_5.2.0.201302132326.jar:
13327 Defl:X 3624 73% 02-13-2013 23:21 326488c7

os/linux/x86_64/libspawner.so
but no debuginfo package.
Thoughts, comments?
This is pretty obviously a breach of packaging guidelines. We shouldn't
be hiding DSOs in archives.
Hmm, I am not aware of any guideline touching this topic (perhaps because it's
not that common). But from practical perspective these jars are extremely
practical because they don't have to deal with JNI file locations and similar
things which ten to be quite variable.
I don't consider this approach hiding, but we could surely improve the tooling
support for it.
WRT original question, I am not sure how to proceed. Even if you generate
debuginfo packages I have to wonder how easy will it be to use in a debugger?
The workaround that I am employing for the moment in PTP is to install a
copy of the binary in %{_libdir}/ptp so that rpm can find it an generate
debuginfo. As for how useful that might be, I don't know. I *think*
gdb matches things up via hashes these days so it might work, and might
for the cdt shared libraries as well.
Whatever the solution, I think we need to improve our tooling to check
inside of archives for binaries. I'm CC'ing the packaging list as well.
