Hello,
I'm new here, so I hope I'll ask my question correctly. I have an assignment to create a "text-based cosmic adventure" and all went well until now. My project is separated into several header and implementation files. Problem arises only when I include certain file in another header file. Compiler writes the famous "myClass was not declared in this scope" error. And I really don't know what I'm doing wrong (or better said what to do).
I have a tip, but better first some code:

Code:
// Location.h
#include "MainMenu.h"
class Location 
{...}

// MainMenu.h
#include "Planet.h"
class MainMenu
{...}

// Planet.h
#include <vector>
#include "Location.h"
class Planet 
{
...
vector<Location> location; // error: 'Location' was not declared in this scope 
...
}
I think there could be some sort of cycle between Location.h and Planet.h. First Location.h includes MainMenu.h, which then includes Planet.h, that includes again Location.h. But I really don't know how to prevent this, because I need all headers to be included.

Do you think this is the reason or is it something else? Could you please show me a solution to this problem?
Thank you very much

Note: When I do not include MainMenu.h in Location.h, the error in Planet.h doesn't occur. but I'd really like to be able to use MainManu functionality (well, better said, I need to, because it controls the whole game).


P.S.: At the beginning of every file I of course have that thing against cycles:
Code:
#ifndef LOCATION_H
#define LOCATION_H
...
#endif
so there shouldn't be any "inclusion cycle problem".
