The Petr4 project is developing the formal semantics of the P4
Language, backed by an independent referene
The Petr4 reference implementation is implemented in OCaml. To install
from source, perform the following steps.
Install external dependencies:
sudo apt-get install m4 libgmp-dev
Check the installed version of OCaml:
If the version is less than 4.06.0, upgrade:
opam switch 4.06.0
Use OPAM to build and install Petr4. This will take a while the first time
because it installs OPAM dependencies.
opam pin add petr4 .
petr4 is merely a P4 front-end. By default, it will parse
a source program to an abstract syntax tree and print it out, either
as P4 or encoded into JSON.
