I'm sorry, but this is not a ROS question. It reads like a C++ issue.

As we have far too many questions here already, we must try to stay on-topic as much as possible.

Because of this, I've closed your question. Please post it on a forum dedicated to these kind of issues, such as Stack Exchange or Stack Overflow.
