Hi Cliff,

The earlier error is resolved now. It was some compilation problem. Now I am getting some other error:

EAL: Detected 24 lcore(s)

EAL: Detected 1 NUMA nodes

EAL: Auto-detected process type: PRIMARY

EAL: Detected static linkage of DPDK

Hi Team,

I have to run dpdk on mellanox nic. I have compiled dpdk 21.08 with the following commands:

meson --prefix=$(pwd)/build build
ninja -C build
ninja -C build install
ldconfig

While running the application I am getting following error:

Also I cannot find mlx5 compiled libs in the dpdk build folder. Please help me in resolving this issue.
