[dpdk-dev] Build is broken in dpdk-next-net

[Andrew Rybchenko]

Hi all,

Build is broken in dpdk-next-net for me on Ubuntu 16.04.4:

lib/librte_vhost/fd_man.c: In function ‘fdset_pipe_read_cb’:
lib/librte_vhost/fd_man.c:284:2: error: ignoring return value of ‘read’, declared with attribute warn_unused_result [-Werror=unused-result]
   read(readfd, charbuf, sizeof(charbuf));
   ^
lib/librte_vhost/fd_man.c: In function ‘fdset_pipe_notify’:
lib/librte_vhost/fd_man.c:324:2: error: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Werror=unused-result]
   write(fdset->u.writefd, "1", 1);
   ^

$ gcc --version
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609

As I understand it is broken in ad94ade905454401b705be9e06b19e54a1c78148
vhost: add pipe event for optimizing negotiating

Andrew.
