I`m having two projects (x64).

A. written in C (wxWidgets) B. written in c++

A compiles fine. B uses funcions of A. When I try to compile, I`m getting several errors.

I suggest that the reason for the errors is the same for all, so I mention only the first: It says: strlen: identifier not found.

But I have included the headers:

#include <stdio.h>

#include <string.h>

So, currently, I have just no idea where to start to search for the reason of the errors. May it be that I have c and c++ files? May it be that I compile for x64?

Thanks for help!
