Generates the JSON configuration for the behavioral-model (bmv2), as well as the PD (Protocol Dependent) library C/C++ files, if needed.

• To install p4c-bm on your machine:
  • sudo pip install -r requirements.txt
  • sudo python setup.py install
• Using p4c-bm
  • Try p4c-bm -h
  • --json to generate a JSON representation of the P4 program
  • --pd to generate the PD C++ code

• Compiling the PD

  You can copy the generated C++ PD file to your project directory (and compile them with your app).

  You can also use the pd_mk directory to compile the PD code:

  • cd pd_mk/
  • ./configure --includedir=<target_dir_for_headers> --libdir=<target_dir_for_libraries>
  • make 'P4_PATH=<path_to_p4_program>' 'P4_PREFIX=<prefix_for_apis>'
  • make install

  You will find the PD headers (fixed and generated) in target_dir_for_headers and the libraries (libpdfixed and libpd) in target_dir_for_libraries.

  If your main project also uses autotools, you may be able to integrate pd_mk directly in your infrastructure with AC_CONFIG_SUBDIRS
