Re: [dpdk-users] Fwd: FW: DPDK Compilation Error

[Sergey Matov <smatov@mirantis.com>]

Hello Rajaraman.

Currently I've no experience running DPDK on 32 bit machines.
However all recommendation I could give to you is to check out related
problems, such as http://dpdk.org/ml/archives/dev/2014-August/004695.html
AFAIC it seems that using sse version 3 is kind of hard requirement for
configuration you want to compile.
