Thread: problem with compiling

Hello..

I have 2 headers.

The first one is:

Code:

#ifndef SESSION_HEADER
#define SESSION_HEADER

#include "header2.h"
class session {
public:
	session() { }
	thread *threads;
	thread *get_thread(unsigned short id);
	..etc..
};

#endif

And the other one is:

Code:

#ifndef THREAD_HEADER
#define THREAD_HEADER

#include "header1.h"

class thread {
public:
	thread(session *se) { s = se; }

	session *s;
	thread *next;
};

#endif

Now im getting errors when compiling, I think because the compiler wants to include header which would need the first header.. I know for extern, but is this the way how should I do it? And if I should, how would be the right way to do it?

Thanks for help guys

You are using only pointers to the other class, so a forward declaration should do.
e.g.

Code:

#ifndef SESSION_HEADER
#define SESSION_HEADER

// #include "header2.h" // not needed

class thread;

class session {
public:
	session() { }
	thread *threads;
	thread *get_thread(unsigned short id);
	..etc..
};

#endif
