Tom:
You may need re-read the man pages. Also, I highly recommend the book
"Programming with GNU Software" by O'Reilly & Associates
(http://www.oreilly.com/catalog/prognu/) as a very good starting point for
understanding gdb, GNU make, gcc, etc.
To answer your question, To start up gdb, use
gdb executable core
Put your executable file name (i.e. ./circle) in as "executable" and then
put in the core dump (i.e. ../lib/core) as "core". That will open the
debugger and point you to the line that caused the crash and core dump.
From there, you will use commands like backtrace, print, up, down, etc. The
commands are probably best learned from the man pages or a book.
Good luck,
-Cj
