What I tried was to install the "centos-release-xen" repo, and run "yum upgrade" in my CentOS 6.8 box, this way, I can receive a new Kernel for it, which is "3.18.34-20.el6.x86_64", and here is the DPDK build error now: --- ........... CC eal_common_dev.o cc1: warnings being treated as errors /root/rpmbuild/BUILD/dpdk-16.04/x86_64-default-linuxapp-gcc/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.c: In function 'igbuio_pci_probe': /usr/src/kernels/3.18.34-20.el6.x86_64/include/linux/slab.h:582: error: inlining failed in call to 'kzalloc.clone.0': --param max-inline-insns-single limit reached /root/rpmbuild/BUILD/dpdk-16.04/x86_64-default-linuxapp-gcc/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.c:383: error: called from here make[8]: *** [/root/rpmbuild/BUILD/dpdk-16.04/x86_64-default-linuxapp-gcc/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.o] Error 1 make[7]: *** [_module_/root/rpmbuild/BUILD/dpdk-16.04/x86_64-default-linuxapp-gcc/build/lib/librte_eal/linuxapp/igb_uio] Error 2 make[6]: *** [sub-make] Error 2 make[5]: *** [igb_uio.ko] Error 2 make[4]: *** [igb_uio] Error 2 make[4]: *** Waiting for unfinished jobs....

I'm still looking for a way to build and package the latest DPDK on CentOS 6.8 box. I appreciate any help... Thanks! Thiago
