hi openman , any solutions? I met the same errors as you.

the no such unistd.h problem can be just add new file name the unistd.h
contents :

ifndef _UNISTD_H

define _UNISTD_H

include <io.h>

include <process.h>

endif /* _UNISTD_H */

then add it to your /vs path / vc/include dir .

I'm working on the other errors.
