The ³.mm² extension is required for source that contains both C++ and
Objective-C, thus called Objective-C++. Not required for pure C++ source.
A couple ideas:
1. Be sure to add the C++ source files to your target. (ie, look for the
checkmark in the target column)
2. Any objective-c source that creates C++ declared objects also must have
the ³.mm² extension and must include the C++ header files.
