unresolved external errors

This problem has stumped me all afternoon. I have 2 function in the gameInititalize header, they are defined in Engine.cpp, and called in Entry.cpp. I had same problems with some DirectX function calls, but they when away when I did pragma for 2 directX libraries. Help is appreciated.

I managed to fix it. I didnt define functions gameRun() and gameEnd() in the Engine cpp file.
