program works for 32bit but not for 64.

Below is a test-program I have been using.

 

I'm compiling in Visual Studio 2008 on a 64 bit Windows 7 box and I have
5.1.4 of lua. Luabind seems to be 0.9.1.

 

When I compile for a 64 bit platform and I typedef MY_TYPE to int, the
program works. If I typedef it to size_t, greet never gets called

When I compile for a 32 bit platform both cases work. (obviously since
int and size_t are then the same size)

 

Does anyone have any suggestions for 64bit?

 

Thanks,

Steve

 

#include <iostream>

#include <luabind/luabind.hpp>

using namespace std;

 

// int works, size_t doesn't.

typedef size_t MY_TYPE;

 

class NP {

public:

      NP(MY_TYPE number) : m_number(number) {}

 

      MY_TYPE greet(string& s, string& t)

      {

            cout << s << m_number << t << endl;

            return m_number;

      }

private:

      MY_TYPE m_number;

};

 

int main()

{

      using namespace luabind;

 

      lua_State *myLuaState = lua_open();

 

      open(myLuaState);

 

      module(myLuaState)

      [

            class_<NP>("NumberPrinter")

            .def(constructor<MY_TYPE>())

            .def("greet", &NP::greet)

 

      ];

 

      luaL_dostring(myLuaState,

            "Print2000 = NumberPrinter(2000)\n"

            "Print2000:greet(\"Hello \", \" world!\")\n"

            );

 

      std::cout << "sizeof(LUA_INTEGER) = " << sizeof(LUA_INTEGER) <<
std::endl;

      std::cout << "sizeof(int) = " << sizeof(int) << std::endl;

      std::cout << "sizeof(long) = " << sizeof(long) << std::endl;

 

      lua_close(myLuaState);

 

      return 0;
