[DanielB2]

Here is my code http://rafb.net/p/noi06840.html

Now I will paste a list of errors that I keep getting, Any help appreciated

[MrSpigot]

Just declaring your classes before they are used isn't always sufficient. E.g you declare

class MoveList;

before it is used in

class RandomPlayer : public BackgammonPlayer

but in this case you actually need the complete class definition of MoveList before the definition of RandomPlayer.
If you were using a pointer to MoveList in RandomPlayer you would be able to get away with it because the pointer size is known.

So you need to do a bit of re-ordering in the header file. You may find it easier if you put each class in a separate header file and only include the ones you need.

Also, use bool instead of boolean.

I'm sure there will be several problems after those are sorted. Hard to see the wood for the trees at the moment!

There is no such keyword as boolean -- its bool
