does not name a type ERROR

Hi,

I'm having trouble compiling, after writting a few lines of code, suddenly my compiler throws me an error. The error is :

GameWorld.h:38: error: ‘AsteroidList’ does not name a type

Here's the code that is related :

GameWorld.h

Code:

#ifndef GAMEWORLD_H
#define GAMEWORLD_H
#include <iostream>
#include <cstdlib>
#include <sstream>
#include <fstream>
#include <QApplication>
#include <QGridLayout>
#include <QPushButton>
#include <QPainter>
#include <list>
#include <vector>

#include "AsteroidList.h"
#include "Asteroid.h"
#include "AsteroidType1.h"
#include "AsteroidType2.h"
#include "Player.h"
#include "t_List.h"

using std::cout;
using std::istringstream;
using std::ifstream;
using std::string;
using std::cin;
using std::list;
using std::vector;

class GameWorld
{
  Player p;
  list<Asteroid*> L;
  list<Asteroid*>::iterator i;
  vector<Asteroid*> V;
  t_List<Asteroid*> tList;

  public:
    // Error is here
    AsteroidList li;
    void loadData(char*,char*,int);
    void drawPlayer(QPainter&);
    void drawAsteroid(QPainter&);

  private:
    int dataType;
};

#endif

Here is my header file for #include "AsteroidList.h"

Code:

#ifndef ASTEROIDLIST_H
#define ASTEROIDLIST_H
#include <QPainter>
#include <vector>
#include <list>

#include "AsteroidNode.h"
#include "Asteroid.h"
#include "AsteroidType1.h"
#include "AsteroidType2.h"
#include "GameWorld.h"

using std::cout;
using std::vector;

class AsteroidList
{
  public:
    AsteroidList();
    AsteroidNode* first() const;
    void addAsteroidPoint(string,float,float);
    void addAsteroid(string,float,float,int,int,int);
    void drawAsteroids(QPainter&, int, string,int,float,float);
    void drawAsteroid(QPainter&, QPolygonF,float,float);
    void checkAsteroids(QPainter&, int);
    void display();
    void setNull();

  private:
    Asteroid *a_first;
};

#endif

I have no idea what happened. Can anyone share any ideas?

"GameWorld.h" #includes "AsteroidList.h" that #includes "GameWorld.h"
Get rid of all the unnecessary #includes in your headers.
Headers should only #include what is necessary for them to compile.
e.g. I don't see a reason why "AsteroidList.h" should #include "GameWorld.h"
Kurt

Try including AsteroidList after

#include "Asteroid.h"
#include "AsteroidType1.h"
#include "AsteroidType2.h"

Thanks alot! I'm sorry about my unnessary includes because my assignment happened to be so large I sometimes get really messed up. Its the first time I'm doing C++.

Thanks ZuK and Desolation!
