DPDK does not build on gcc 4.4, as it complains due to strict-aliasing rules in virtual_pmd and link_bonding_mode4 tests, with no errors in next gcc versions:
CC virtual_pmd.o CC test_link_bonding_mode4.o cc1: warnings being treated as errors /root/dpdk/app/test/test_link_bonding_mode4.c: In function ?test_mode4_expired?: /root/dpdk/x86_64-native-linuxapp-gcc/include/rte_ring.h:645: error: dereferencing pointer ?pkt.409? does break strict-aliasing rules /root/dpdk/x86_64-native-linuxapp-gcc/include/rte_ring.h:729: error: dereferencing pointer ?pkt.409? does break strict-aliasing rules ... cc1: warnings being treated as errors /root/dpdk/app/test/virtual_pmd.c: In function ?virtual_ethdev_stats_reset?: /root/dpdk/x86_64-native-linuxapp-gcc/include/rte_ring.h:645: error: dereferencing pointer ?pkt.338? does break strict-aliasing rules /root/dpdk/x86_64-native-linuxapp-gcc/include/rte_ring.h:729: error: dereferencing pointer ?pkt.338? does break strict-aliasing rules This patch fixes the compilation by disabling these warnings.
