Well, do you have a MYCLASS pointer named pMyClass in one of your source files? The extern reference allows the compiler to proceed with compiling your file because you're telling it there IS a pointer named pMyClass somewhere in one of the project's files. It believes you. When you get to the linker, the linker is going to demand that you told the truth and want to know where the hell you're hiding it.
