[dpdk-users] [vpp-dev] vpp-verify-master-opensuse build failure triage

Tue Nov 28 12:31:53 CET 2017

Hi Gabriel,

I just submitted a patch (https://gerrit.fd.io/r/#/c/9597/) to VPP to fix thisissue. 
I've added you to the review so you can take a look.

In order to verify that the new patch fixes the issue, people should first run:

$ rpm -e vpp-dpdk-devel && rm dpdk/dpdk-17.08.tar.xz

to trigger a rebuild and reinstall of the dpdk package...

Cheers,
Marco
