p4c-bm

Generates the JSON configuration for the behavioral-model (bmv2).

NOTE: This repository is no longer under active development or maintenance. We recommend that you instead consider using the currently developed open source P4 tools, which are p4c and behavioral-model.

Important: the PD has been moved out of this repository and split between the bmv2 repository (for fixed part of the PD) and the new p4-build repository (build infrastructure for the auto-generated / program-dependent part of the PD).

Usage

• To install p4c-bm on your machine:
  • sudo pip install -r requirements.txt
  • sudo pip install -r requirements_v1_1.txt if you are interested in compiling P4 v1.1 programs
  • sudo python setup.py install
• Using p4c-bm
  • Try p4c-bmv2 -h
  • --json to generate a JSON representation of the P4 program
  • --pd to generate the PD C++ code
  • --p4-v1.1 if your input program is a P4 v1.1 program
• To install in a non-default location, you can use:
  • python setup.py build install --prefix <your_path> [--single-version-externally-managed] --record install_files.txt
  • cat install_files.txt | xargs rm -rf if you need to uninstall later on
