# Builds and installs all tools needed for developing and testing P4 support in
# ONOS.
#
# Tested on 16.04 and 18.04.
#
# Recommended minimum system requirements:
# 4 GB of RAM
# 2 cores
# 8 GB free hard drive space (~4 GB to build everything)
#
# To execute up to a given step, pass the step name as the first argument. For
# example, to install PI, but not bmv2, p4c, etc:
# ./install-p4-tools.sh PI
# -----------------------------------------------------------------------------
# Exit on errors.
