Answer 1

It says the header is not found and IIRC there's no header file "piece.h" in the standard. If you get this when compiling a source code/project you found online - try to find and read the documentation, a good open source project usually comes with a good documentation. If the problem persists, try to contact the developers and inform them of a missing file from their project/repository.
