Zephyr + Openthread compilation problem

[andy9a9]

Dear maintainers!

I tried to build the samples/light_switch_sensor with zephyr project and it failed.

Is there something special what should I set, like CONFIG_OPENTHREAD_MLR=n? Is there some special version needed? See err.log for more details.

Thanks,
Andy

Next question is, why did you chose the OpenThread variant, while the posix Linux is using a native sockets? For example in oc_connectivity_init

// Linux
int
oc_connectivity_init(size_t device)
{
  OC_DBG("Initializing connectivity for device %zd", device);

  ip_context_t *dev = (ip_context_t *)oc_memb_alloc(&ip_context_s);
  if (!dev) {
    oc_abort("Insufficient memory");
  }
  oc_list_add(ip_contexts, dev);
  dev->device = device;
  OC_LIST_STRUCT_INIT(dev, eps);

  if (pthread_mutex_init(&dev->rfds_mutex, NULL) != 0) {
    oc_abort("error initializing TCP adapter mutex");
  }

  if (pipe(dev->shutdown_pipe) < 0) {
    OC_ERR("shutdown pipe: %d", errno);
    return -1;
  }
  if (set_nonblock_socket(dev->shutdown_pipe[0]) < 0) {
    OC_ERR("Could not set non-block shutdown_pipe[0]");
    return -1;
  }

  memset(&dev->mcast, 0, sizeof(struct sockaddr_storage));
  memset(&dev->server, 0, sizeof(struct sockaddr_storage));

  // ...

  if (setsockopt(

// zephyr
int oc_connectivity_init(size_t device)
{
    otError           error;
    struct otInstance *instance = openthread_get_default_instance();
    otSockAddr        sockaddr;

    memset(&socket, 0, sizeof(otUdpSocket));
    memset(&sockaddr, 0, sizeof(sockaddr));
    
    sockaddr.mPort = 5683; // CoAP port

    if (!otUdpIsOpen(instance, &socket))
    {
        error = otUdpOpen(instance, &socket, handle_udp_received, NULL);
        error = otUdpBind(instance, &socket, &sockaddr, OT_NETIF_THREAD);   
    }
}

Can't this port be working with Coap instead of OpenThread?
