As with most things worth learning, by reading the documentation.
I find the GDB quick Reference sheet especially useful.

You have to make sure that gdb knows _where_ to locate the source files.
Most often this is directly handled by using the 'dirs' command to tell
it in which directories to search for your source files. Also, make sure
you aren't asking for it to print the value of some macro item....it
can't do anything with that since there is nothing in the symbol table.
