I don't either? They're defined in libwxbind, no compilation errors there?

These are the order they're linked in apps/wxlua/src/Makefile and it
works there.
 -l$(WXLUABIND_LIB) -l$(WXLUA_LIB) -l$(WXLUADEBUG_LIB)
-l$(WXLUASOCKET_LIB) $(LUA_LIBS)

Having to know these int tags is not great, they can be looked up
dynamicly from the classname, but I'd like to see how slow that really
is. It might be something that could be cached as needed, for example
the callbacks only need s_wxluatag_wxEvent so it'd no great thing to
just cache that. I'd like to wait on that though since it'd be a
pretty big change and I still have to get the coroutine stuff working
again.

Let me know if you can figure this out and commit your other changes
before I start with things again.
