The above commad has to list the complete program.
Is it working ?

Don't know what the program does, but unless you have it prompting for
some input the 'run' command will run the program to completion. setting
a break point after the run is like closing the barn door after the cow
is out.
My previous use (heavy ) would be
(gdb) break funcname
(gdb) break 10
(gdb) run

You might also try ddd. It is a GUI wrapper of gdb.
