I am crossposting this to .programming and .unix because I don't
really know the source of the problem - my incompetence with C++ or my
compiler (gcc).

This isn't really POV-related ATM but will be at some point in time.
Anyway...

I am developing a set of classes for vector operations. Every class is
separated in a separate pair of .hh and .cc files.

The problem occurs when trying to include header file A in B and B in
A. For example,

// $Id: cvector.hh,v 1.6 2001/07/27 13:20:39 peter Exp $

#ifndef CVECTOR_HH_
#define CVECTOR_HH_ 

#include "ctransf.hh"

class CVector {
   ... // snipped some stuff to save space
   void Transform (const CTransform &);
};

#endif

// $Log: cvector.hh,v $
// Revision 1.6

and then I have this file:

// $Id: ctransf.hh,v 1.2 2001/07/27 14:12:13 peter Exp $

#ifndef CTRANSF_HH_
#define CTRANSF_HH

#include "cvector.hh"

class CTransform {
   ... // snipped some stuff here too
   void CreateRotate (const CVector &);
};

#endif

// $Log: ctransf.hh,v $ 

The compiler complains that in ctransf.hh, CVector was not declared in
this scope. More precisely, it complains about a parse error before &.
How come? I do include cvector.hh, I do have the proper pre-processor
directives to avoid multiple inclusion...

I was able to build the project by substituting the includes with
dummy class declarations like 'class CVector;' in ctransf.hh and
'class CTransform;' in cvector.hh, but I am 100% sure this will lead
to terrible memory problems during runtime, even though it linked
properly. Right?

Please help me before I lose all my hair over this problem.
