语法错误丢失;之前*

我有一个这样的头文件:

#pragma once
#include "gamestate.h"
#include "ExitListener.h"

class InitialGameState : public GameState
{
public:
  InitialGameState(Ogre::Camera *cam, Ogre::SceneManager *sceneMgr, OIS::Keyboard      *keyboard, OIS::Mouse *mouse, Ogre::Root *root);
  ~InitialGameState(void);
  virtual bool update(Ogre::Real time);
  virtual void pause(void);
  virtual void start(void);
  void keyPressed(const OIS::KeyEvent &e);
  void keyReleased(const OIS::KeyEvent &e);
//private:
ExitListener *mFrameListener;
};

问题是我从VC 8中得到以下错误:

InitialGameState.h(16) : error C2143: syntax error : missing ';' before '*'  
InitialGameState.h(16) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int  
InitialGameState.h(16) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int  

(它们都指最后一行)

我有一节课 ExitListener.h 这就是为什么我不知道错误的原因

编辑:exitListener.h:

#pragma once
#include <Ogre.h>
#include <OIS/OIS.h>
#include <CEGUI/CEGUI.h>
#include <OgreCEGUIRenderer.h>
#include "Thing.h"
#include "InitialGameState.h"

using namespace Ogre;
class ExitListener : public FrameListener, public OIS::KeyListener, public     OIS::MouseListener
{
public:
ExitListener(OIS::Keyboard *keyboard, OIS::Mouse *mouse, Camera *cam, std::vector<Thing*> &vec): 
  mKeyboard(keyboard), r(0.09), mContinue(true), mRunningAnimation(false),
mMouse(mouse), mYaw(0), mPitch(0), things(vec), mCamera(cam), mWDown(false), mSDown(false), mADown(false),
mDDown(false)
{
  things = vec;
  mKeyboard->setEventCallback(this);
  mMouse->setEventCallback(this);
}
bool frameStarted(const FrameEvent& evt);   
bool keyPressed(const OIS::KeyEvent &e);
bool keyReleased(const OIS::KeyEvent &e);
bool mouseMoved(const OIS::MouseEvent &e);
bool mousePressed(const OIS::MouseEvent &e, OIS::MouseButtonID id);
bool mouseReleased(const OIS::MouseEvent &e, OIS::MouseButtonID id);

void setOwner(GameState *g);

private:
  AnimationState *mSwim;
  Radian r;
  Radian mYaw;
  Radian mPitch;
  OIS::Keyboard *mKeyboard;
  OIS::Mouse *mMouse;
  Camera *mCamera;
  bool mContinue;
  bool mRunningAnimation;
  std::vector<Thing*> &things;
  bool mWDown;
  bool mADown;
  bool mDDown;
  bool mSDown;
  GameState *mOwner;
};

编辑2:

事实证明,这个问题可以通过一个转发声明来解决,然后将另一个头直接包含在我的.cpp文件中。

谢谢。
