The current build system > in DPDK is really imperfect. The issue is due to enablement of a new feature for every platforms without dependency check. Actually the patch should disable CONFIG_RTE_SCHED_VECTOR for every non-x86 platforms. Another fix is discussed in another thread to disable the feature inside the code if the platform cannot support it (currently AVX is required).
