timer_create problem

[Aitor.Viana.Sanchez at esa.int]

Hi all,

i am having a look to the CANFestival v3.0 trying to port it to RTEMS. I 
get the code already running over RTEMS but I have a problem with the 
timer_create POSIX function. 

The main.c source code gets inside the RTEMS configuration which includes:

...
#define CONFIGURE_MAXIMUM_TIMERS            10
...

/** RTEMS Configuration */
#define CONFIGURE_MAXIMUM_RTEMS_TIMERS CONFIGURE_MAXIMUM_TIMERS
...

/** POSIX Configuration */
#define CONFIGURE_MAXIMUM_POSIX_TIMERS          CONFIGURE_MAXIMUM_TIMERS
...

When I try to create a timer calling the timer_create routine:
        ....

        memset (&sigev, 0, sizeof (struct sigevent));
        sigev.sigev_value.sival_int = 0;
        sigev.sigev_notify = SIGEV_THREAD;
        sigev.sigev_notify_attributes = NULL;
        sigev.sigev_notify_function = timer_notify;

        status = timer_create (CLOCK_REALTIME, &sigev, &timer);
        if (status != 0)
                        MSG_ERR(errno, strerror(errno), status);

        .....

i got an error which is quite weird. I got the errno = 22 which is 
"invalid argument", that means that the specified clockid (CLOCK_REALTIME) 
is not defined. Nevertheless, i tried to call the function clock_gettime, 
which also needs the clockid (CLOCK_REALTIME) as a parameter, and i got no 
problem at all.

I am using RTEMS 4.6.5.

Do you have any idea that could help me to solve this problem ?

Cheers
