I am guessing that you are linking rump_server without the
export-dynamic flag. However, I do not know for sure without recreating
a setup where your problem manifests.
One should note that drv-netif-dpdk is not a consumer-level product,
i.e. one that can be used without technical expertise. We are happy to
provide support on the big picture, but it is not anyone's job on this
list to provide free assistance for every issue, and users are expected
to be able to work out typical problems pertaining software development
on Unix systems.
