Re: Expose functions in need?

Nigel,
     Thanks for your reply.  With your help, I changed the luabind module like this:
  
#define LUABIND_REGISTER_CLASS_BEGIN( classname ) \
                 luabind::class_<classname> x(#classname); \
                 x.def(luabind::construtor<>());
 
#define LUABIND_REGISTER_CLASS_FUNC(classname, funcname) \
                if ( FuncInUse(#funcname) ) \
                { \
                       x.def(#funcname, &classname::funcname); \
                }
 
#define LUABIND_REGISTER_CLASS_END(L) \
              luabind::module(L)[ x ];    

FuncInUse() is for checking if the "funcname" is needed in particular lua file (actually i go through the file and 
get the set of functions being used, and then check if the registering func is in the set).

I am happy to see that it works fine. And the total memory use sharply shrink. Thanks again!

Albin
