Does your title have anything to do with your question? If so, would you mind clarifying where C comes into play? — danielschemmel, Apr 08 '15 at 05:44

Your question is a bit vague but the problem could be name mangling. Put your C++ function in an extern "C" { ... } block in order to give it C linkage and prevent the compiler from mangling the name.

I have already tried this but still facing the same issue(Undefined Reference). will you please elaborate it more so that I can try again. – Prashant Mehta Apr 08 '15 at 05:52
So, perhaps the problem is in path where cpp -files located or incorrect run of compiler? – VolAnd Apr 08 '15 at 06:07
