/usr/lib/debug/usr/lib64/libpython2.7.so.1.0.debug does exist

$ objdump -s -j .gnu_debuglink /usr/lib64/libpython2.7.so

/usr/lib64/libpython2.7.so:     file format elf64-x86-64

Contents of section .gnu_debuglink:
 0000 6c696270 7974686f 6e322e37 2e736f2e  libpython2.7.so.
 0010 312e302e 64656275 67000000 9ede5e96  1.0.debug.....^.

But gdb does not find (or even search for) the split debug symbols. I've tried both 7.3.1 and 7.5 and get the same behaviour.

Running strace through gdb and grepping I see only two references to "/debug".

I thought this was supposed to work automatically? Am I missing something? Do I need to specifically enable it?

Shouldn't you also have added -g(/gdb) to CFLAGS/CXXFLAGS, then?
Comment 2 Peter Waller 2012-11-19 09:58:13 UTC 
Wow, that did the trick. I feel stupid. Thanks, Jeroen.

I naively expected the splitdebug feature to add whatever flags it might need.
