You have a collision between C++ macros and functions defined by perl.
This usually happens when an '#include <iostream>' is present somewhere
in your XS or a header included from there.
You can work around that by doing a
#undef do_open
#undef do_close
#include "Ui.h"
...
If you need to use perl's do_(open|close), use them with their full
names Perl_do_(open|close).
