I have been trying to compile WRCAD and MASTER branches of FastHenry2 and in both cases I run into the following errors:

The WRCAD looks a bit different, but it seems to boil down to the same issue.

Any ideas on how to solve this problem?

So I was trying the same thing but on kubuntu:
I found the definition of timestuff in
"resusage.h"


#ifdef FOUR
#define NOTOTHER 1
#include <sys/time.h>
#include <sys/resource.h>
struct rusage timestuff;
#endif

#ifdef FIVE
#define NOTOTHER 1
#include <sys/types.h>
#include <sys/param.h>
#include <sys/times.h>
struct tms timestuff;
#endif

/* define macros for time and resident memory usage checks */

static double dtime = 0.0;
static long sectime, utime;

#ifdef NOTOTHER

#ifdef FOUR                     /* 4.2,3BSD (tested: Sun4, IBM6000, DEC5000) */
#define starttimer getrusage(RUSAGE_SELF, ×tuff); \
sectime = timestuff.ru_utime.tv_sec; \
utime = timestuff.ru_utime.tv_usec
#define stoptimer getrusage(RUSAGE_SELF, ×tuff); \
dtime = (double)(timestuff.ru_utime.tv_sec - sectime) \
        + 1.0e-6*(double)(timestuff.ru_utime.tv_usec - utime)
#define DUMPRSS                 /*  */
#endif /* FOUR */

#ifdef FIVE                     /* for System V (tested: HP300) */
#define starttimer times(×tuff); \
utime = timestuff.tms_utime
#define stoptimer times(×tuff); \
dtime = (timestuff.tms_utime)-utime; \
dtime /= HZ
#define DUMPRSS                 /*  */
#endif /* FIVE */

#else                           /* default - no timers */

#define starttimer              /*  */
#define stoptimer               /*  */
#define DUMPRSS                 /*  */

#endif /* NOTOTHER */


I think it has to do with some compatibility flags, flags but I really don't understand it.

I think I found the problem. GCC has changed to be more extrict.
It is explained here
ht*ps://w*w.openmx-square.org/forum/patio.cgi?mode=view&no=2904

It seems the solution is to add extern to the definiton of timestuff in resusage.h

however now I have the following problem

[SOLUTION]

you should add static keyword to timestuff definition in resusage.h

also add static to FILE* fp in precond.c
