As others have pointed out, a big part of your problem is that you're trying to compile plain C (or Objective-C) files that contain C++ code. You need to put C++ code into .cpp or .mm files. (It is possible to tell Xcode to treat a file as C++ or Objective-C++ regardless of its extension, but you'll just confuse yourself if you go that route.)

The C++ code is in .cpp files. I looked a File Types in the workspace guide, and I agree, I do not need more confusion.


What is the difference between ".m" and ".mm" files? A .m file can not access C++ code?

Thanks!

Xcode uses the file extension as a hint to know how to compile the file. Files ending in .m will be compiled with the Objective-C compiler mode, where C++ is nonsensical; .mm will be compiled as Objective-C++, where both runtimes can be used.
