A PCH is a Precompiled Header file. It sounds like you've got an #INCLUDE somewhere that wants something defined in this header. Are you doing a "Build"? The compiler should normally create the PCH files for you, if you're building the solution. If you don't want to use PCH's, you can tell the compiler to not use them by going into the project settings and unselecting the Precompiled heading option (depending on the version of the compiler, it's in a different spot). The only downside to doing this is that it will slow down your builds.
