- Check which gcc was used when compiling kernel
- Use that gcc version instead of default one.

Or:

- Disable IGB kernel module in DPDK .config

I've been running 18.04 for the past month or so and it seems very solid.
So +1 for that suggestion.

I'm trying to build dependencies for linux-generic odp for the same 
Ubuntu which Travis ships in his image. Which a little bit buggy for 
cross arch support (libpcap-dev package conflicts between arches,
some other dependencies issues). But in general it works.  But I think 
you are right it's better to switch to some fresh image, like Ubuntu 
18.04 LTS.

Re: [lng-odp] unrecognized command line option '-fstack-protector-strong'

2018-06-27 Thread Bill Fischofer 
Is this an ODP question or a DPDK question? Is this unique to Ubuntu
14.04?  I notice that release goes out of support in April 2019 so I'm
wondering if it's still an important release to carry.
