GDB - debug external library, have source code

Question

I am using gdb to debug a package that is using an external library. I have the source code of the external library. How do I make gdb load this source code as well? Thank you!

Answer 1

To make GDB find sources for the library, use the dir command. More info here.

Answer 2

Do you know if the external library was compiled with the "include debugging symbols" flag set? I assume it was not. If you can recompile with that flag set it will make debugging easier.
