Hi,
I changed CFLAGS to following in XBoard Makefile (any better way?). Now there seems to be some problems with timeZone.
Code: Select all
CFLAGS = -std=c11 -Wall -Wextra -pedantic
Note that I used -Weverything but I removed this since it produced massive number of warnings.
Now:
Code: Select all
#if HAVE_GETTIMEOFDAY
#include <sys/time.h>
//#include <sys/timeb.h>
struct timeval timeVal;
struct timezone timeZone;
gettimeofday(&timeVal, &timeZone);
tm->sec = (long) timeVal.tv_sec;
tm->ms = (int) (timeVal.tv_usec / 1000L);
#else /*!HAVE_GETTIMEOFDAY*/
I get:
Code: Select all
backend.c: In function ‘GetTimeMark’:
backend.c:17839:21: error: storage size of ‘timeZone’ isn’t known
struct timezone timeZone;
^~~~~~~~
What can I do ?
Edit: Corrected title.
Farewell.

Says
here the timezone argument of gettimeofday is obsolete. Apparently it is no longer defined in the system headers used with the C11 standard. Just set the second argument of gettimeofday to NULL, and delete the declaration. It was just passed as a dummy anyway, and not used for anything.

I added code like this , is it OK ?
Code: Select all
[...]
#if defined __STDC__
struct timezone {
int tz_minuteswest;
int tz_dsttime;
};
#endif /* __STDC__ */
[...]
Farewell.
