I tried to change the library order to match this one but it still 
doesn't work (same errors).

I then tried to use the hand-made Makefile but I get:

frm@genius:~/work/wxLua/apps/wxlua/src$ sudo make
make[1]: Entering directory `/home/frm/work/wxLua/modules/lua'
cd include; make all

And this did not work with both a static and a shared build of wxWidgets.

Last, I searched for the unresolved linker symbols: i.e. 
s_wxluatag_wxWindow, s_wxluatag_wxBitmap, s_wxluatag_wxEvtHandler, 
s_wxluatag_wxEvent and I found that they are all declared as extern 
symbols at the beginning of some CPP files (like wxlstate.cpp) but then 
they are not defined anywhere.

How did you manage to compile these sources ?
Do I have to run some bind generator ?
Or you have some un-committed sources in your local copy ?
