Can anyone see why the compile keeps giving me an error. It compiled before and then I went to the computer lab and changed some of the files. When I uploaded them back to my home computer the compiler keeps saying that there is a syntax error even though the lab computers compile the same code with no complaints or warnings. The compiler I am using is Dev C++ v4.9.8.0 Here is the warning: Model.h:18: syntax error before `*'' token Model.h

@Sneftel
Yeah I thought about the string thing causing the compiler to barf but I have already tried commenting it out and I still get the same error

@langguy
The computers in the lab run redhat linux with gcc 3.2.2
My home computer is WinXP. Like I said before the code was
working before I went to the lab and made changes. The change
being that Polygon used to be called Face.

Update on the problem

The problem seems to be that the compiler doesnt think that Polygon has been defined even though Vertex.cpp which contains all of the function definitions for class Polygon compiles with no errors.

Ok so I fixed the problem by changing the name of Polygon to CPolygon. WTF is up with that?

check all the files that are included at any point for Polygon and chances are you will find some windows header with a function called Polygon. like so often when using common names there might have been some guys at ms deciding that they were using it first and the rest should just go and use another name. wingdi for example, though i wouldnt know why this should be included in a project thats also going to be used under linux.
