Using GDB in a self hosted system

OK, today’s lessons for me were using makefiles and enabling threads to do
port i/o. The next newbie roadblock that I have run into is with debugging
a program. Is it possible to debug a program on a self hosted system? The
literature says the only supported usage for GDB is for cross-platform
development. If it’s possible, what are the steps? Is there any hope of
doing useful (I mean real-life source line level debugging) debugging
without slapping down 2.5K for CodeWarrior? I guess if the OS works well, I
might be able to swing it later.

Thanks,
John

Sure, why not? GDB works fine on self-hosted RTP and DDD is very helpful
too.

When I start a GDB session, where does the input/output go (using Photon in
a pterm window)?

Also, I have a licensed copy of QNX 4.24 with Watcom C++ 10.6. Can I use
this under NTO?

Thanks,
John

But when I try to debug my program with gdb, it display ‘cannot get bounds
of the function’. ;-(

Because you forgot to type ‘cont’ command after ‘run’. Under neutrino/gdb
all programs stop before entering main(), so you have to continue them
explicitly.
