Luabind, do not collect my garbages please?

Hi everyone, 

 

I m binding C++ classes and functions with Luabind in my C++ app.

 

My promblem is that when lua_close() is called, it try to delete pointers
wich are already being handle via a C++ memory manager. In short, I have no
need for Lua to collect my garbages from a C++ class being created in Lua.

 

Here is a simplify version of my work:

 

.cpp

 

            module(in_lua)

            [

                  /// Base class for all classes.

                  class_<Object, boost::shared_ptr<Object>>("Object)

                  .def(constructor<>())

                  ,

                  class_<Actor, Object, boost::shared_ptr<Object>>("Actor)

                  .def(constructor<>())

                  .def("SetGeometry", &Actor::SetGeometry)

                  ,

                  class_<Cube, Object, boost::shared_ptr<Cube>>("Cube")

                  .def(constructor<Float, Float, Float>())

            ];

 

.lua

 

myGeo = Cube(1,1,1);

 

myActor = Actor();

myActor:SetGeometry(myGeo);

 

App onExit():

 

1 - delete all C++ objects.

3 - lua_close().

 

I m using the boost::shared_ptr because it does not call the C++ object
destructors when lua_close() is called. 

 

It all works fine, but my promblem occurs when myActor:SetGeometry(myGeo);
is present, lua_close() try to delete myGeo when it has already been
deleted. And BAM!

 

What am I missing? I ve been stalled on this for many hours. I m currently
trying to make sens of how the adopt method could help me with this... how
far am I?
