Bug ID: 681
Summary: DPDK 20.11.1 failed to build for x86 machine types
Product: DPDK
Version: 20.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: meson
Assignee: dev@dpdk.org
Reporter: qlinqlin@yahoo.com
Target Milestone: ---
While build with commands:
meson build
meson -Dmachine=atom
works fine, build with x86 machine types failed. e.g.
meson -Dmachine=silvermont
The problem seems with compiler setting. File
$(DPDK_ROOT)/config/x86/meson.build has code:
# we require SSE4.2 for DPDK
if cc.get_define('__SSE4_2__', args: machine_args) == ''
message('SSE 4.2 not enabled by default, explicitly enabling')
machine_args += '-msse4'
endif
The error is: "Could not get define '__SSE4_2__' "
