Oops, the perils of applying debug patches on top of debug patches...
Can you add a...
#include <stdio.h>
at the top of the file, e.g, after '#include <string.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
-
+#include <stdio.h>
#include <X11/xshmfence.h>
#include <xcb/xcb.h>
#include <xcb/dri3.h>
Then it should compile, albeit with some format warnings, but those
shouldn't affect the outcome.
