Re: [gtkmm] Compiling my first gtkmm program - HELP!!

[Matthew Walton <matthew alledora co uk>]

Well I don't think it's the Makefile this time. I'd like to know what 
this is doing here:

>   class Wimm : virtual public Gtk::Window {

I didn't even know you could do virtual inheritance, and I certainly 
have no idea what it means. Since the errors look like they might be 
related to virtual function tables and they're certainly something to do 
with something down in the Gtk::Window ancestor classes, perhaps you 
could try

class Wimm : public Gtk::Window {

instead and see what happens. Unless there's a particular reason you 
need to do it, in which case someone more knowledgeable than I will have 
to take over, or I'll have to go and read about it, because I've never 
heard of virtual inheritance in C++. But I guess it must exist in some 
form or it wouldn't compile (or is that me putting too much faith in g++?)

Anyway, that's all I can offer this time... glad my other tip helped. I 
honestly didn't notice these error messages really last time, as they 
were a bit buried amidst the others.
