converting project code to MFC

[tmorlan]

Hey guys, i'm working on a project for school where I have to make a GUI for a text based adventure game that was a previous project. I am trying to create an instance of a class called Player, and I am getting a linkage error. I think it must have something to do with the way I have <include>'d everything, but I can't seem to find the problem. Here is the output from the program, and if i need to post something else from the program please let me know. Thanks.

Are you declaring global variables in an h-file and including it in multiple C++ files? If so check out __declspec(selectany) and put it in front of each global variable in your h-file.

__declspec(selectany) int SomeGlobalVaribale
