[ovs-dev] Build failures with openvswitch-{2.9.1, 2.8.3} due to missing rte_mempool_ops_get_count DPDK symbol

[Markos Chandras]

Hello,

I was trying to update the openSUSE package to 2.9.1 (2.8.3 has the same
issue) but the following build error occurs

[   58s] libtool: link: gcc -Wstrict-prototypes -Wall -Wextra

[   58s] lib/.libs/libopenvswitch.so: undefined reference to
`rte_mempool_ops_get_count'

The 'rte_mempool_ops_get_count' symbol seems to be an internal DPDK one
since it doesn't seem to be exported in the map file

http://www.dpdk.org/browse/dpdk/tree/lib/librte_mempool/rte_mempool_version.map

This was added in commit 91fccdad72a253a3892dcb3c4453a31833851bb7
("netdev-dpdk: Free mempool only when no in-use mbufs."). I am not sure
how that ever built since that symbol was never exported by the
rte_mempool DPDK library

Any clues?
