SOS ！help me

童心心

int main()
{

using namespace luabind;

lua_State* L = lua_open();
luabind:pen( L );
object stateTable = get_globals(L);//["stateTable"];

for( object::iterator curState = stateTable.begin();curState != stateTable.end();
  curState++ )
{
  printf("%d\n",object_cast<int>(stateTable[curState.key()]));
}
...
}


my lua file:
table.lua
stateTable=
{ IDLE = 1,
  APPROACH =2,
  ATTACK = 3,
  ESCAPE = 4,
}

我实现不了lua中的数据向c++中数据的转换。急煞我也，到底object_cast怎么使啊？
大家帮我检查一下我的代码，给我提个建议或者解决方案。谢谢！
