Thank you , earlier I had enabled only 'CONFIG_RTE_BUILD_COMBINE_LIBS=y' , compilation is successful after enabling 'CONFIG_RTE_LIBRTE_VHOST=y' configuration.

It's been a while since I've used OVS 2.4 but from what I remember with DPDK 2.0 it used vhost cuse and there were extra steps required to enable the vhost cuse interfaces in DPDK which could crop up at compilation as you are seeing, I'm wondering is this the issue your hitting. Have you followed the build instruction from the 2.0 documentation, specifically install the fuse and fuse-devel (libfuse-dev for ubuntu) and then updating the config/common-linuxapp file in DPDK with the following. CONFIG_RTE_BUILD_COMBINE_LIBS=y CONFIG_RTE_LIBRTE_VHOST=y Steps to build are also available in the link below. https://github.com/openvswitch/ovs/blob/branch-2.4/INSTALL.DPDK.md It might be worth giving it a shot. (Please note vhost-cuse support has since been removed from OVS with DPDK and replaced with vhostuser) > > The GTP protocol functionality is implemented in OVS 2.4.0 code base. > So I have to use OVS 2.4.0 since merging the GTP packet handling code > to OVS > 2.8.0 due to lot code changes between OVS 2.4.0 and 2.8.0 A lot of work has been put in to cleaning up the DPDK aspect of OVS to make sure it plays nicely when hitting issues like this, normally I would encourage users to move to 2.8 but it seems that's not an option for you unfortunately.
