How did you install dpdk-19, with meson buil or setup?

I am using dpdk-19, same version that you posted, have set the SDK as well and following the same steps for its installation. I am getting this while issuing make command. cmake is fine

Try using meson to build the latest LTS DPDK 19:

meson build
ninja -C build
ninja -C build install

The API doesn't seem to have changed between these two versions, so it should still work correctly.

I have compiled and not being able to view results.

Do the same code works with l2fwd?

This program needs to receive SIGUSR1 to print statistics: https://github.com/STEELISI/dns-proxy/blob/master/main.cpp#L1195-L1203 My tests used TRex to send packets on a second computer connected to the one running dns-proxy to get statistics on packets returned, so it could take network card behavior into account.
