[Xenomai-help] native queue and timeout

[Xenomai-help] native queue and timeout

Hello all. I grabbed svn 3956 and am having a slight problem with
2.6.25.6.

 

I spawn a native thread that does the following:

 

        int res;

        

        printf("reading..\n");

        res = rt_queue_read(&ql, &level_data, sizeof(unsigned long int),
TM_INFINITE);

        printf("done?\n");

        if(res!=sizeof(unsigned long int)) {

            rtlog(RTLOG_LEVEL_EMERG, "level thread went wrong. retval
%d", res);

            abort();

        }

 

The queue "ql" is bound to successfully. The queue is created in another
userspace application. My binding code looks like this:

 

    if(rt_queue_bind(&ql, "rtlog level", TM_NONBLOCK)) {

        fprintf(stderr, "failed to bind to rtlog level queue -- is
rtlogd running?\n");

        abort();

    }

 

"ql" is: RT_QUEUE ql;

 

Now, in the native thread, the call to rt_queue_read always returns with
-ETIMEDOUT  (-110) which makes no sense because I am passing
TM_INFINITE. I made sure my include files were up to date.

 

Any idea?

 

Thanks,

Steven

If running the trunk/, then you need to fully rebuild the Xenomai userland libs
as well; the ABI has changed in that area.

Philippe,

I have done this as well. I should have specified. I am running /trunk, btw.

I will double check that I copied the libs properly.

It appears I copied the libnative.so.2* instead of the 3*. Thanks for the heads up. Everything is peachy-keen now.
