You should also define -DDEBUG=1 (and make sure -DNDEBUG=1 is *not* defined). -g3 provides maximum debugging information. For example, symbolic constants through #define's will be available. -ggdb provides gdb extension. I don't believe there are any at the moment, but I got into the habit of using it (in case they show up in the future). NDEBUG is Posix C and used for "Release" builds, so it should be undefined. Some libraries/implementation sneak in additional code when DEBUG is defined, so I define it. Sorry about not answering your original question :( Jeff
