#include woes

It's been a while since I've used C++, and I've gone a little rusty. One problem I managed to overcome in the past was situations where two header files include each other... For example

In resource.h

Code:

---

#include "resourcemanager.h"

---

In resourcemanager.h

Code:

---

#include "resource.h"

---

... but now I've forgot how to get around it. Can anyone help me out? :)

There is no easy way around this. One common source of this problem is when two classes need each others declaration. In that case use a forward declaration of one of the classes:

Code:

---

// b.h
class A;

class B {
  A* doSomething();
}

// a.h
#include "b.h"

class A {
  B* doSomething();
}

---

Thanks! That was the method that I used previously (but had forgot the syntax for!).

Bah, it turns out to have not worked so well afterall..

Code:

---

error C2027: use of undefined type 'cResource'

---

I'm guessing that is related to the forward declaration. The problem is that each class needs to access the members of the other class, and so I don't see any way around it.

Any other ideas? :(

Put the member accesses into the source files.
