Ha, you are talking about a lua script i think. My problem is the lua C 
code. I can not debug into that code.
Is it generated without debug info??

Found it. What should happen if one calls a non existing function on a 
name space?

Oke, will dig into this soon.

By the next two i mean that

wxart2d_BindingInit s_wxart2d_BindingInit;

is seen suddenly and therefore the call to this from its construtor.

m_binding.GetBindingList()->Append(&m_binding);

And thus the bindings are initialized properly.
Without any reference to the binding library in my exe/program code, the 
whole binding library is skipped.

I am not so sure about this, at least i had to do trick to make sure one 
module was intialized before the other. Still it works oke. wxModule is 
realy meant to intialize things before the wxApp is starting.
I think it could help us.

wxModule is not so much for static things, but it may solve adding 
bindings before wxLuaState is used.

No CMake solves/writes all the makefiles for me.

Thanks!
