[wxlua-users] link error

I am trying to build wxLua 2.6.0.3 (cvs checkout + build all modules +
shared) with Visual C++ 6.0 (service pack 4)
 and wxMSW 2.7.1 (shared, multilib), on Windows XP Pro,
but when linking the wxlua_msw27_wxbind.dll I get an unresolved external
error.
(lua5.1.dll, wxlua_msw27_lua.dll and wxlua_msw27_wxlua.dll build ok)

Error description:

So I added a destructor in class wxLuaTreeItemData in file wxbind.h like so:

 virtual  ~wxLuaTreeItemData(void){};
 This does not help. Does anyone know how to fix this? And would you be so
kind to share this info with me ?
