Hi.
On my etch system, the library headers declare the availability of
POSIX timers, but clock_gettime is not actually in the library. The
attached program fails to compile with
/tmp/ccs726Ek.o: In function `main':
test.c:(.text+0x20): undefined reference to `clock_gettime'
collect2: ld returned 1 exit status
(Julien, I'm CC-ing you in case there's something weird on this machine
and it turns out it's not actually a bug.)
Regards,
Juliusz
#include <stdio.h>
#include <time.h>
#include <unistd.h>
int
main()
{
#if defined(_POSIX_TIMERS) && _POSIX_TIMERS > 0
int rc;
struct timespec ts;
rc = clock_gettime(CLOCK_MONOTONIC, &ts);
if(rc < 0)
perror("clock_gettime");
else
printf("POSIX timers OK.\n");
#else
printf("No support for POSIX timers.\n");
#endif
return 0;
}

from the manpage:
NOTES
Most systems require the program be linked with the librt
library to use these functions.
Looks like you forgot -lrt. Closing as PEBKAC.
Cheers,
Julien
