How do I compile this program for the openrisc processor? I tried uncommenting each of these 3 lines and got errors...btw, this is for a FuseSOC generated soc on a de0 nano board (which I finally got working, UART is finally displaying some output after including or1k-support.h (didn't find that documented anywhere :) Do I need some special h/w attached to use these time functions?


/* define only one of the next three defines */
#define GETRUSAGE /* Use getrusage(2) time function */
//#define TIMES /* Use times(2) time function */
//#define TIME /* Use time(2) time function */
