Because skb_vlan_tag_present renamed in Linux 3.19 (commit: df8a39d) and this commit backported in this kernel. This error can be also fixed, but another compile error pops up. This is hard to keep up, because kernel version is old (2.6.32) but backported latest commits. We are not able to rely on kernel version checks or define checks. If you don't need KNI you can either: 1- Disable it from configuration file 2- Compile kernel modules against newer kernel version using RTE_KERNELDIR, like: "make RTE_KERNELDIR=/tmp/latest_linux_version" As far as I can see you are using spec file to compile, is this spec file distributed with DPDK? If so, perhaps you can share your updates to spec file? > > Might be a totally different problem now, I don't know... :-) > > Best, > Thiago
