how to determine location of source?

I haven't need this type of info much, but "info sources" has been
handy sometimes.

There are several ways of doing this depending of what you are trying
to do. There is the "dir" command. But perhaps you have moved the
sources elsewhere, and want to translate the encoded source locations
into your new location. Have a look at "set substitute-path".
That's as much as remember off the top of my head.

PS: Sounds like you could benefit greatly from reading the GDB
    documentation. Best advice I ever received in my first year
    of Engineering School.
