Here's a basic question. Can gdb/insight debug code from .so files?
I have a library, compiled with debug information, and a main program, also with debug info. If I start gdb with the main program, does gdb automatically dig up the debug info from any .so libraries used by the main program? Can I set breakpoints on the source code in the .so file?
Or do I have to link statically for debugging purposes?
Thanks,
Bill

It should work fine. There are a couple of quirks, though.

In my experience, when I attach to a process that includes say
libc.so.1, gdb says no debugging information found. I thought maybe I
had to recompile libc.so.1. Is that not the case? Maybe/probably I'm
doing something wrong.

No, GDB doesn't know anything about the shared libraries until they're
loaded. If you set a breakpoint on 'main', and run the program to it,
then GDB will know about the shared libraries, and you'll be able to
set breakpoints on them.
