Hello,
Has anyone successfully built a OpenContrail 3.0 vrouter with
dpdk support and used it successfully? Although, I can get something to
compile, it does not seem to have all the necessary startup scripts and
configuration files connected to it. I must be missing something? Any
suggestions on how to compile this correctly? Or maybe there is a repository
that already has the packages for 3.0 somewhere? The standard PPA and the
tcpcloud PPA don't seem to have the dpdk vrouter package in them ...
Thank you!
Jay

Hello,
I'm resending this, since it was probably missed by many people
since it was sent during a US holiday. Any help or suggestions is appreciated.
Thank you!

Folks,
Happy Memorial Day weekend!
I'm hoping someone here can help me with a problem that I'm
running into. I've had some success with installing OpenContrail 2.x from the
available Ubuntu packages. However, now I am trying to trying to compile
OpenContrail 3.0 from source and I'm running into problems. Any suggestions
would be appreciated. I am roughly following the directions from
http://juniper.github.io/contrail-vnc/README.html.
I have been able to build most of the the packages following the documentation
at that link. However, I ran into a problem where it was not trying to build
the contrail-vrouter-dpdk package. The best I could tell, this was initially
failing because the dpdk directory was missing from the "third_party"
directory. There is no mention on the docs to install this (I would have
thought fetch_packages would have downloaded it), but I added it manually, and
then it appears that the vrouter with dpdk attempts to build. It gets pretty
far, but then it fails with the following error:

I'm not sure why its trying to call rcu_barrier exactly, but as far as I can
tell rcu_barrier is a function that is part of the linux kernel. The
rcu_barrier function is not defined anywhere in the contrail source code, and
there does not appear to be anything including the linux kernel headers. I'm
running this on Linux Ubuntu Trusty 14.04.01 (latest patches installed) with
kernel 3.16.0-70-generic.
This is roughly the procedure that I am following:
apt-add-repository ppa:opencontrail/ppa
apt-get update
apt-get install <lots of packages>
Manually install libuv, cassandra-cpp-driver, and cassandra-cpp-driver-dev
repo init -u
[email protected]:Juniper/contrail-vnc<mailto:[email protected]:Juniper/contrail-vnc>
repo sync
Python third_party/fetch_packages.py
wget http://downloadmirror.intel.com/22777/eng/dpdk-2.0.0.tar.gz
tar xfvz dpdk-2.0.0.tar.gz
cp -pr dpdk-2.0.0 third_party/dpdk
scons vrouter
Any suggestions or comments would be very much appreciated.
Thank you,
