Do you know about inclusion guards?

// myheader.h
#ifndef MYHEADER_H
#define MYHEADER_H

// Your class here

#endif

Most likely the error you're getting is a multiple definition error for classA because you used a header without inclusion guards multiple times.

This should never be done. In any case include guard as Naure described should solve the problem. But I suggest you relook at your dependencies and see how to avoid one of the two #includes.

Ah, and next time copy paste the error msg in your post, it's more understandble than "XYZ is giving error".. :)
