That means that SSE4 and AVX/AVX2 instructions are disabled. If i get it right that also means that vector PMDs are disabled (at least i40e) as it requires SSE4.1 instructions. All this means that performance of VPP linked against your dpdk libraries will be significantly slower. > > I'm going to try your suggested steps and will let you know how it goes. > >> >> Thanks, >> >> Damjan > Thanks, > Marco > > >> >> >>> >>> On 12 Apr 2017, at 11:33, Marco Varlese <marco.varl...@suse.com> wrote: >>> >>> BTW, in case you're wondering which commands I am using to build: >>> >>>> >>>> make bootstrap >>>> make build (using build-release produces the same issue) >>> >>> >>> Regards, >>> Marco >>> >>> On Tue, 2017-04-11 at 09:27 +0200, Marco Varlese wrote: >>>> >>>> Hi, >>>> >>>> I am facing a build issue with the latest VPP and not sure if others have >>>> seen >>>> the same?
