You need to link your app with gthread library, and in the code, at the very beginning, call


You need to lock gdk mutex before entering the main loop.


You may look up, for example, balsa sources (not that it is a best example, but it is a sufficiently complex one).

Generally, threading GDK (or I think most GUIs) with threads is a non-trivial thing (threads are non-trivial, GUI are non-trivial, and the system mixing these together becomes quite complex). If you can steer clear of it, do.
