Hi
When building 1.7.1 or 1.8.0-rc4 on recent CentOS 6 (6.6) I got this error: In file included from /home/makerpm/rpmbuild/BUILD/dpdk-1.8.0/lib/librte_eal/linuxapp/kni/ethtool/igb/e1000_osdep.h:41, from /home/makerpm/rpmbuild/BUILD/dpdk-1.8.0/lib/librte_eal/linuxapp/kni/ethtool/igb/e1000_hw.h:31, from /home/makerpm/rpmbuild/BUILD/dpdk-1.8.0/lib/librte_eal/linuxapp/kni/ethtool/igb/e1000_api.h:31, from /home/makerpm/rpmbuild/BUILD/dpdk-1.8.0/x86_64-native-linuxapp-gcc/build/lib/librte_eal/linuxapp/kni/e1000_82575.c:38: /home/makerpm/rpmbuild/BUILD/dpdk-1.8.0/lib/librte_eal/linuxapp/kni/ethtool/igb/kcompat.h:3870: error: conflicting types for 'skb_set_hash' include/linux/skbuff.h:620: note: previous definition of 'skb_set_hash' was here make[8]: *** [/home/makerpm/rpmbuild/BUILD/dpdk-1.8.0/x86_64-native-linuxapp-gcc/build/lib/librte_eal/linuxapp/kni/e1000_82575.o] Error 1 It seems the assumption that skb_set_hash is missing in CentOS prior to version 7 is not valid anymore. Didn't see a fix of it in trunk or in the patches. Thanks, Barak
