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?
Who is including the "xxx.h" header? If that header has C++ keywords
in it (aka class, etc.) then all files that include that header have
to be compiled using the C++ compiler (.mm or .cpp files).
If you don't want that to happen then you need to rework what is
exposed in your header(s).
