In spite of #including the header files I get: "... was not declared in this scope"

Hi,
I am writing an application consisting of some files that do inherit from a common base class "Piece". When I try to instantiate an object based on "Piece" inside another class that is also based on "Piece" I get an error like this: "... was not declared in this scope".
I can however instantiate objects from these classes inside other non-related classes. Creating a minimal compilable piece of code to highlight that problem would involve changing the whole code base (bad design :-s) so I just wanted to know if anybody here is able to quickly spot the problem. you can get the sources from here: http://gitorious.org/shatranj/shatranj/trees/master (There is a Download master as tar.gz button on the right side of the page.) Compiling it involves: qmake && make


Here is a piece of code that highlights the problem in "king.cpp"

#include "king.h"
#include "chessboard.h"
 
// Qt
#include <QPair>
#include <QDebug>
 
#include "rook.h"
 
King::King(ChessBoard const* board, Color color, int file, int rank)
    : Piece(board, Piece::King, color, file, rank)
    , m_hasMoved(false)
{
  Rook* r;
}
 
...

#include "king.h"
#include "chessboard.h"

// Qt
#include <QPair>
#include <QDebug>

#include "rook.h"

King::King(ChessBoard const* board, Color color, int file, int rank)
    : Piece(board, Piece::King, color, file, rank)
    , m_hasMoved(false)
{
  Rook* r;
}

...

To copy to clipboard, switch view to plain text mode 

If you remove Rook* r; the code will compile without any further issues. Can anybody tell me what I am doing wrong?

Thanks in advance

King inherits Piece which has enum containing Root enum. I wonder which the compiler takes when you use "Rook *r".

May change the enum say it says instead ID_Rook, etc to prevent collisions with classes of the same name.

Thanks alot :-).
