Containers? I've built Docker containers from most recent Coccinelle versions and used to use them in my custom Travis CI build jobs; the version included in Ubuntu 18.04 is rather old, and apparently it doesn't catch some transformations that later versions do [1]. I'm sure it's somehow possible to use such containers in GitHub Actions as well. > Should we try compiling it from source for this job? It's not that difficult to build Coccinelle from source once you figure out its OCaml dependencies... And luckily those dependencies seem to be rather stable: we can pass the same dozen or so package names to 'apt-get' to install all its build dependencies both on ubuntu:18.04 and :20.04 base images. However, installing dependencies and building Coccinelle takes almost 5 minutes on my machine; I don't think we'd want to add that much overhead to every CI build. > Should we > consider moving off of coccinelle and onto a different tool? Is there any other comparable tool out there?!
