I am trying to compile the code below:

#include <sys/types.h>
#ifdef _TIMES
#include <sys/time.h>
#include <sys/times.h>
#include <limits.h>
#else
#include <time.h>
#endif
#include <sys/resource.h>
#include "libU77.h"

real etime_(real t[2])
{
#ifdef _TIMES
  struct tms tm;

  times(&tm);
  t[0] = (real) (tm.tms_utime + tm.tms_cutime) / (real) CLOCKS_PER_SEC;
  t[1] = (real) (tm.tms_stime + tm.tms_cstime) / (real) CLOCKS_PER_SEC;
#else
  struct rusage tm;
  float meg = 1000000.0;

  getrusage(RUSAGE_SELF, &tm);
  t[0] = (real) (tm.ru_utime.tv_sec + (tm.ru_utime.tv_usec) / meg);
  t[1] = (real) (tm.ru_stime.tv_sec + (tm.ru_stime.tv_usec) / meg);
#endif

  return (real) (t[0]+t[1]);
}


I get the following error upon compilation:

In file included from etime.c:56:
/usr/include/sys/resource.h:58: field `ru_utime' has incomplete type
/usr/include/sys/resource.h:59: field `ru_stime' has incomplete type
*** Error code 1

Stop.

The /usr/include/sys/resource.h contains the following:

/*
 * Resource utilization information.
 */

#define RUSAGE_SELF     0
#define RUSAGE_CHILDREN -1

struct  rusage {
        struct timeval ru_utime;        /* user time used */
        struct timeval ru_stime;        /* system time used */
        long    ru_maxrss;              /* max resident set size */


What do I need to do to the code to make it right?

Thanks in advance.
