Hi Prashant, Are you referring to the rte_* libraries ? I had actually compiled them using the setup script ($(RTE_SDK)/tools/setup.sh) and then linked the PMD lib extension I've made and then linked the pktdump eventually, before seeing the problem. However, building it all as an app. didn't show any issue.
I will try to redo the building/linking just to make sure. Thank you!
