Re: [OMPI devel] Build failure on FreeBSD 7

That's good that you guys revive this thread, I almost forget about it.



  Thanks,

The code you're referring, is not part of the libevent. It was one of my "fixes" around for problem on OS X (where kevent is not able to work nicely with pty). It works on MAC as the code trigger an error so there is no need for the timeout ... I'll make the corrections over the weekend.

Hi, Jeff...

This may depend on how you ran the app on FreeBSD -- did you run on
the localhost only?

We have/had a problem when running locally with regards to kevent --
I'm not 100% sure if we've fixed it yet.  Let me check...

This test was performed locally, yes. I'm short on machines at the moment to perform any proper distributed tests.

After digging a little deeper, it turns out that the kevent() call in
opal/event/kquene.c:
        if (kevent(kq,
          kqueueop->changes, 1, kqueueop->events, NEVENT, NULL) !=
1 ||
           (int)kqueueop->events[0].ident != master ||
           kqueueop->events[0].flags != EV_ERROR) {

seems to hang in freebsd 7. Changing the NULL parameter to, lets say
1000, causes the function to return and print out the error message:


error %d (%s)", __func__, errno, strerror(errno));

The simple non-blocking send/recv app used to test this then runs to
completion. Compiling OpenMPI on linux and running this same app
produces no errors.

Any ideas?

Thanks.
