Building ONOS

...

In order to run ONOS using onos.py, you will need a correctly built ONOS package in your VM.

We recommend sure building ONOS in your

...

Mininet VM or server using buck:

cd ~/onos
buck build onos

Make sure that the build completes without errors - without a correct correctly built ONOS package, you will not be able to start ONOS.

Info

title	Legacy build process using Maven

It's also possible to use the legacy mvn build process if absolutely necessary, by setting ONOS_TAR to point to the ONOS package:

cd ~/onos

mvn clean install  # or mci for short; needs to complete without errors

onos-package  # once again, needs to complete without errors

cd ~/onos/tools/dev/mininet

# See below for more details on options for mn

sudo env ONOS_TAR=/tmp/onos-1.7.0.openflow.tar.gz mn --custom onos.py ...

Make sure that you use the correct ONOS_TAR file name for your version of ONOS. Also make sure that it is a gzip/tar archive:

sudo file /tmp/onos-1.7.0.openflow.tar.gz

/tmp/onos-1.7.0.openflow.tar.gz: gzip compressed data, from Unix, last modified: Thu Jun  2 15:08:11 2016

A final alternative is to build elsewhere, copy the ONOS tar.gz file to your development VM, and set ONOS_TAR appropriately.
