cross reference problem

I cant get the following code compiled. The following code is an abstraction of the problem I met in my development. How do you usually solve this kind of problem in your project?

#ifndef TEST1_H
#define TEST1_H

#include "test2.h"

class Test2;

class Test1 {
public:
	typedef struct Nested {} N;
};

#endif

4) The "right way" to include http://www.cplusplus.com/forum/articles/10627/

Files cannot inlucde each other. In test1.h it is completely unnecessary to include test2.h. Not even the forward reference is required.

Either include or forward reference, but not both.
