No, not your code, it works fine on Debian, so I expect it should as well on Alpine. I had a chat with @emery and he seems to concur that it might be caused by an incompatibility due to Alpine’s Musl vs. Glibc. I did not track the error yet, having to deal with NixOS first. See updated post in https://dream.public.cat/t/d2-2-mvp-alpha-upsycle/154/2?u=how where I made some progress, but my ignorance of NixOS combined with the lack of documentation on setting up NixOS for DREAM development makes me go slow.
I could build ocaml-seaboar using nix flakes.
But I fail to add I found the way…make as a dependency to run opam install . in ocaml-conduit-dream. I need to sleep on it and will come back to it on Saturday.
