Still running into this, would like a fix

[marsam]

Would you mind trying the unstable channel? I can build/run ocaml-ng.ocamlPackages_latest.ocaml-lsp on x86_64-linux and x86_64-darwin.

[Zenthial]

That worked, sorry for the trouble. I thought I was using the unstable channel, but I actually wasn't

[Zenthial]

This does then result in a linker error when attempting to run dune build, using the unstable version of dune_3. With the linker error being "undefined reference to `__isoc23_strtol'"
