Since commit `7f6bffb dpdk: support build with external & multilib toolchains' applied, it added var-HOST_CC_ARCH in which has option `-march=**' to enable specific SSE for specific arch that causing SSE mismatch error while compiling [snip] | recipe-sysroot-native/usr/lib/i586-wrs-linux/gcc/i586-wrs-linux/8.2.0/include/ xmmintrin.h:1232:1: error: inlining failed in call to always_inline '_mm_sfence': target specific option mismatch | _mm_sfence (void) | ^~~~~~~~~~ | In file included from git/lib/librte_eal/linuxapp/eal/eal_thread.c:16: | git/i686-native-linuxapp-gcc/include/rte_atomic.h:26:19: note: called from here | #define rte_wmb() _mm_sfence() | ^~~~~~~~~~~~ | git/lib/librte_eal/linuxapp/eal/eal_thread.c:155:3: note: in expansion of macro 'rte_wmb' | rte_wmb(); [snip]
Choose `-march=native', which will select what is available on the processor. Although it disable previously `-march=**' in var-HOST_CC_ARCH, but others options in var-HOST_CC_ARCH (such as security flags `-fstack-protector-strong -D_FORTIFY_SOURCE=2') still works.
