VC++ not recognizing 'GameBoard' in code

[huyvtq]

I have a class Chess with the contructor:
Chess(const GameBoard& argGameBoard,int,int,Color,int); //line 1
and a property:
GameBoard& mGameBoard; //line 2

to creat a reference to one obj of GameBoard: :mGameBoard(argGameBoard) at constructor.

But when It's compiled (by VC2005++). This errors occured:
at line 1

1>e:\vc2005\chessgame\src\Chess.h(34) : error C2059: syntax error : '<cv-qualifer>'
1>e:\vc2005\chessgame\src\Chess.h(34) : error C2238: unexpected token(s) preceding ';'
 

and at line 2:

1>e:\vc2005\chessgame\src\Chess.h(69) : error C2143: syntax error : missing ';' before '&'
1>e:\vc2005\chessgame\src\Chess.h(69) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

It seem that Compiler don't know what GameBoard is in class Chess.
Here class GameBoard I have defined and included. It have a property:
Stack<TurnHistory>& aReport;

Who can tell me what it is?

Tks a lot!

I can help you but I need to see chess.h.

The errors can be due to a number of things.
