1 year ago With the latest version of the code in this p4lang/tutorials repository, and a recent version of the open source P4 development tools installed on an Ubuntu 20.04 system, I am not able to reproduce this error.
What OS are you running on?
Have you modified the code in your local copy of the tutorials repository? Or are you trying to run the code in the tutorials/exercises/ecn directory with no changes?
How did you install the open source P4 development tools? e.g. one of these?
- cloned this tutorials repo and ran
vagrant up - downloaded a VM image that had the tools already installed (if so, which one?)
- some other steps? What were they?
This page lists a couple of ways that you can get an Ubuntu 20.04 or 22.04 system into a state that has all of the P4 open source development tools installed that should be able to run unmodified exercises in this repo without such errors: https://github.com/jafingerhut/p4-guide/blob/master/bin/README-install-troubleshooting.md
