Yes, travis is switching.  We need to adapt to it sooner or later.  It
is possible that the best solution here is to disable the particular
warning, for example by adding -Wno-error=inline to some appropriate
CFLAGS.

I tried a few approaches…
-Wno-error=inline worked
Thanks

Or maybe this line in linux-build.sh needs adjustment:
find ./ -type f | xargs sed -i 
's/max-inline-insns-single=100/max-inline-insns-single=400/'

Re: [ovs-dev] DPDK build errors on travis

2017-08-08 Thread Darrell Ball 
We ran these builds many times with 17.05.1 and they were fine.
Is Travis switching over to a new build environment ?

I saw a notification

“This job ran on our Trusty environment, which is gradually becoming our 
default Linux environment. Read all about this in our blog: Trusty as a default 
Linux is coming and take note that you can add dist: precise in your 
.travis.yml file to continue using Precise.”
