Hello,

I'm relatively new programming ObjectiveC and Cocoa, and I'm trying to add some C++ code to my existing ObjectiveC/Cocoa code using Xcode 3.1. I have my C++ files in a separate .mm files (as the documentation says to), and my C++ headers are in a xxx.h file. When building the code, I keep getting my C++ 'class' and everything associated with it as undefines. Is there some compiler flag I have to set that is not being set automatically, or is there something else I am not doing correctly?

Perhaps you need to extern "C" {} your prototypes? Objective-C, after all, "is" C.
