Even with it applied the remaining include subsequently at rte_vect.h:67 pulls in x86intrin.h which still ends up including smmintrin.h. Long story short is that the mentioned issues like the following still occu= r: /usr/lib/gcc/x86_64-linux-gnu/5/include/smmintrin.h:67:1: error: inlining failed in call to always_inline =E2=80=98_mm_testz_si128=E2=80=99:= target specific option mismatch _mm_testz_si128 (__m128i __M, __m128i __V) So I'd ask to still disable CONFIG_RTE_SCHED_VECTOR in the default config via my patch.
