If I include stdio, I get a conflict types error "time_t" in types.h. The previous declaration was in base.h (In the include folder of the mercury sdk). I tryed deleting the typdef unsigned long time_t out of base.h but then I got a "expected declaration specifiers or ... before * token" error at line 115 so I tryed deleting this line to and after this it says undefined referenc to sprintf again. Sorry for the bad English
