[oe] How can I use gdb in oe?

[Brian Hutchinson]

Hi Journeyer,

I assume you know how to add gdbserver to your root filesystem image or
install the gdbserver package on your target.

Mats instructions were spot on for connecting to the target.

There are a bunch of examples/tutorials that explain attaching to processes
etc. like this one:
http://sourceware.org/gdb/onlinedocs/gdb/Server.html

Regards,

Brian
