The joys of decoupling: whenever anyone uses native_compute in a Coq development, Nix CI needs ocaml and findlib as explicit dependencies. Otherwise, one gets the following error, which is at least self-explanatory:

Error: The OCaml compiler was not found. Make sure it is installed, together with findlib.

There's even an issue about this: https://github.com/NixOS/nixpkgs/issues/34657

And a trivial fix that I support, but I haven't cared enough to open a PR. Maybe I should?

if it helps Nix in CI, I'm all for it

in the meantime, I did the dumb fix: https://github.com/coq-community/coqtail-math/pull/1/commits/9038465eeb251a188c8c07e80fccd2bfa9649761

I opened: https://github.com/NixOS/nixpkgs/pull/101058
A similar PR will be necessary for the version in the Coq repository.

I can confirm there's no fundamental incompatibility between native_compute with a local nix OCaml installation, as it is the setup I use

if some improvements of native_compute could help with the Nix packaging, feel free to open a feature request / PR
