Hi Orion,
There are two ways to remove the debugging symbols:
1) strip --strip-debug your_library.so
2) objcopy --strip-debug your_library.so
Below is an example of both approaches:
1) Method using strip:
paul$ objdump --syms libfoo.so | grep debug
0000000000000000 l d .debug_aranges 0000000000000000 .debug_aranges
0000000000000000 l d .debug_info 0000000000000000 .debug_info
0000000000000000 l d .debug_abbrev 0000000000000000 .debug_abbrev
0000000000000000 l d .debug_line 0000000000000000 .debug_line
0000000000000000 l d .debug_str 0000000000000000 .debug_str
paul$ strip --strip-debug libfoo.so
paul$ objdump --syms libfoo.so | grep debug
paul$
2) Method using objdump:
paul$ objdump --syms libfoo.so | grep debug
0000000000000000 l d .debug_aranges 0000000000000000 .debug_aranges
0000000000000000 l d .debug_info 0000000000000000 .debug_info
0000000000000000 l d .debug_abbrev 0000000000000000 .debug_abbrev
0000000000000000 l d .debug_line 0000000000000000 .debug_line
0000000000000000 l d .debug_str 0000000000000000 .debug_str
paul$ objcopy --strip-debug libfoo.so
paul$ objdump --syms libfoo.so | grep debug
paul$
Are there other symbols you are looking to strip?
Hope it helps,
Paul

I'm trying to resolve this packaging issue with Lmod:
https://artifacts.dev.testing-farm.io/4d7bee41-8d21-42fb-8c57-e5ffbf58119f/
debuginfo
BAD /usr/share/lmod/8.7.25/lib/tcl2lua.so in Lmod-8.7.25-2.fc38 on i686
contains debugging symbols
I've dealt with a couple of issues here:
https://src.fedoraproject.org/rpms/Lmod/pull-request/2
but despite all of my attempts the library does not appear to get stripped.
In fact:
]$ strip -g
/home/orion/BUILDROOT/Lmod-8.7.25-3.fc39.x86_64/usr/lib64/lmod/tcl2lua.so.1.0.1
$ file

/home/orion/BUILDROOT/Lmod-8.7.25-3.fc39.x86_64/usr/lib64/lmod/tcl2lua.so.1.0.1:

linked, BuildID[sha1]=aa1ea44979190d0cf530d350f8151ffafeab0f36, not stripped
