I am a long time user of gdb.

You can't "install debug symbols". All of the source code must be
compiled with the gdb or -g option. You need a special makefile or
compile and link all of the source code at once including your top level
api. I am not sure if gdb can use libraries (of the gsl code)  so I
would stick strictly with the source code compiled and linked in the
same directory. I would strongly recommend not using shared libraries
with gdb but rather use static.


That should fix the problem once you have mastered the compile and link
without errors.
