Hi Neil,

> What was the value of RTE_COMPILE_TIME_CPUFLAGS when you built your libra=
ry?  If you added defines for flag support that are not tested for yet in t=
he cpu_feature_table, that would be the error you would see I think

RTE_COMPILE_TIME_CPUFLAGS=3D RTE_CPUFLAG_SSE,RTE_CPUFLAG_SSE2,RTE_CPUFLAG_S=
SE3,RTE_CPUFLAG_SSSE3,RTE_CPUFLAG_SSE4_1,RTE_CPUFLAG_SSE4_2,RTE_CPUFLAG_AES=
,RTE_CPUFLAG_PCLMULQDQ,RTE_CPUFLAG_AVX

For gcc_version >=3D4.6, that value is the same, of course (and all those f=
lags are supported). So it has to be something else...=20

Thanks,

Pablo de Lara
