if u want to include a class in a .mm or a .m file that is defined in a .cpp file or vice versa, u will need to set the compile source as setting to Objective-C++ so it will just compile everything as Objective-C++. the compiler would in essence be treating all your files as if they had a .mm extension in this case.
otherwise if the comiple as source setting is set to according to file extension then a .cpp file will be compiled as C++ and a .mm file will be compiled as Objective-C++. the C++ compiler and the Objective-C++ file are not the same, or maybe i should say the files would not be compiled as the same language.

One simple question about mixing C++ with Objective-C. Is the C++ suffix .cpp ever used or all source files must use the Objective-C Suffix? I assume that when you said hybrid, all source files use the Objective-C Suffic .mm.
