Thanks Ilya, you are right, it works. I missed libmnl-devel.
I get another error today, "undefined reference to `rte_eth_from_rings' "
In my code , rte_eth_from_rings was called in netdev-dpdk.c, and I have
include <rte_eth_ring.h>, and when I compile dpdk with make , not meson ,it
works well.
It is weird.
Hope to get your advice.
Thanks,
YUN
