If have this strange problem, can anyone help me please ???

Say, I have two classes Class1 and Class2.
I have the the stuff (interface and implementation) of Class1 in
class1.hpp and class1.cpp.
The stuff of Class2 is in class2.hpp and class2.cpp.
Both classX.hpp are done with
   #ifndef __CLASSX_HPP_
   #define __CLASSX_HPP_
   ...
   #endif
so I can't include twice the same file.
So far, so good,  I can compile both class1.cpp and class2.cpp.

Now, in Class1, I need a member object of Class2
   class Class1
   {
      Class2 * myClass2;
      ...
   };
Thus in class1.hpp, I include "class2.hpp" so that Class1 "knows"
Class2.

I also need a member object of Class1 in Class2
   class Class2
   {
       Class1 * myClass1;
       ...
   };
Thus in class2.hpp, I include "class1.hpp".

MY PROBLEM IS: THIS NEW SITUATION WILL NOT COMPILE!!!
WHY???

Thanks in advance,
Bramz
