Expected initializer before * token

So I have this header file:

#pragma once

#include "engine.hpp"

namespace spacecubes
{
  extern engine* _engine;
}

and the included engine.hpp:

#pragma once

#include <iostream>

#include "glinclude.hpp"
#include "debug.hpp"
#include "convert.hpp"
#include "renderer.hpp"
#include "global.hpp"

namespace spacecubes {
    void display();

    class engine {
        renderer renderengine;

    public:
        void start(int argc, char* argv[]);
        void stop(int status = 0);
        void poll();

        renderer getRenderEngine() {return renderengine;}
    };
}

What the compiler reported later on was:

g++  -c -o bin/obj/engine.o src/engine.cpp
In file included from src/engine.hpp:9,
                 from src/engine.cpp:1:
src/global.hpp:7: error: expected initializer before '*' token
src/engine.cpp: In function 'void spacecubes::display()':
src/engine.cpp:5: error: '_engine' was not declared in this scope

I don't get it. What did it mean that it expected an init? Thanks in advance!

Replace 

#include "engine.hpp"

with a forward declaration:

namespace spacecubes { class engine; }
