Unfortunately it's usually not that simple on a target device with
very limited space and on top of that in a cross compilation
environment...

The libraries involved (usually gtk+, pango, glib) compiled with
debugging symbols (not stripped!) are large enough - no way to fit
gdb on the target.

What you probably want is a gdbserver on the target and a cross-gdb on
the host. Make sure to use current gdb sources for that - earlier
versions appear to be malfunctioning in this scenario (backtraces make
no sense at all).

Check http://www.delorie.com/gnu/docs/gdb/gdb_134.html for info on how
to use gdbserver. On the host you'll need to tell gdb where to find the
shared libraries for the target.
