    So do you have a question?

    Perhaps you could be so kind as to post the complete error messages, exactly as they appear in your development environment.

    You may want to start by fixing the errors your compiler is telling you about.

    Just a small list to start, many, many more following these.

    Please keep to one thread per subject.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
