Hello, I just got the same error as you Meni. The reason was I had remainings of old installation of DPDK, so I was mixing two versions.
As I wanted to use DPDK installed from packages I had to remove all traces of DPDK from /usr/local directory. The most important were headers (files with names rte_\*) from /usr/local/include directory. So my advice: clean all traces of DPDK installations on your side and install DPDK again. —\ Best Regards,\ Piotr Krysik > W dniu 28.07.2022 o 14:05, meni.d...@sabra-microsystems.com pisze: > > > I use UHD version 4.2 and x410. > > > > So far, I have been using DPDK version 18.11.
