Hi :) I have a problem trying to expose a class to luabind. When i expose a class normally it compiles and works fine, but when i try to expose a class that has inherited a base class (using the "bases<>" call) it brings up errors that i cant seem to figure out. I have made a scaled down test version of the problem which is pasted below.

#include "Dog.h"   //Animal and Dog are both declared in here

extern "C"
{
  #include <lua/lua.h>
  #include <lua/lualib.h>
  #include <lua/lauxlib.h>
}

#pragma comment (lib, "lua-d.lib")
#pragma comment (lib, "lauxlib-d.lib")
#pragma comment (lib, "luabind-d.lib")

#include <luabind/luabind.hpp>

using namespace luabind;

int main()
{
	lua_State *state;

	state = lua_open();

	luaopen_base(state);
	luaopen_string(state);
	luaopen_table(state);
	luaopen_math(state);
	luaopen_io(state);
	luabind::open(state);

	Dog puppy(0);

	luabind::module(state)
	[
		luabind::class_<Animal>("Animal")
		
		.def(luabind::constructor<int>())
		.def("SetAge", &Animal::SetAge)
		.def("GetAge", &Animal::GetAge)
	];

	luabind::module(state)
	[
		luabind::class_<Dog, bases<Animal> >("Dog")
		
		.def(luabind::constructor<int>())
		.def("SetType", &Dog::SetType)
		.def("GetType", &Dog::GetType)
	];

	return 0;
}

Without the "bases<Animal>" part it compiles fine, but with it i get the following errors.

        ]

If anyone could help i would be very thankful.

You shouldn't need to use bases if you have only one base.

luabind::class_<Dog, Animal >("Dog")
