../net/slirp.c:365:9: error: ‘slirp_pollfds_fill’ is deprecated [-Werror=deprecated-declarations]
         slirp_pollfds_fill(s->slirp, &poll->timeout,
         ^~~~~~~~~~~~~~~~~~
In file included from ../net/slirp.c:41:

解法如下：

$ vim net/slirp.c +365
    363     switch (poll->state) {
    364     case MAIN_LOOP_POLL_FILL:
    365         slirp_pollfds_fill_socket(s->slirp, &poll->timeout,
    366                            net_slirp_add_poll, poll->pollfds);
