Fwiw, there was an issue with static linking + some version of pkg-config that comes with RHEL/Centos 7. https://github.com/openvswitch/ovs/commit/252e1e576443#diff-b781fde347898f87c1814ea8961b8e39c2615374b2811e7fc91047e7517d9b57R356 -- David Marchand _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
