It doesn't say that setbomb isn't defined. It says that it's defined but it isn't used, so use it in anything or just remove it. For the second thing, show us the code. For the third thing, make sure you have zcmd.inc in pawno/includes and don't double-click your .pwn file to open it, use pawno instead and then open with it the .pwn file.
