Ocaml packages are not individually overridable

[nomeata]

I am facing the problem that I want to use Ocaml 4.08, but the base package in nixpkgs (1.11.1) is incompatible with 4.08.

I wanted to use a local overlay to bump it to 1.13, but it would not get picked up by other packages, and the reason seems to be that the package set in https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/ocaml-modules/janestreet/default.nix is a simple rec, and does not take part in the global fixed-point of nix packages. Shouln’t this file take base as a parameter and not be a rec set?

Is that intentionally or was it just an oversight? @vbgl?

Oversight. Do not hesitate to contribute improvements! Many thanks.

BTW, recent nixpkgs have base for OCaml 4.08 (0.12.2).

Thanks! I am always a bit hazy on the semantics of the various nixpkgs branches. With “recent” you mean master, but not yet any tagged “release”, right? (Especially if I want a high chance to find packages on cache.nixos.org)

[nomeata]

Hmm, todays master (2cf477f) still has 0.11.1.

BTW, recent nixpkgs have base for OCaml 4.08 (0.12.2).

Is that on a particular branch maybe? (can't fine one, though)

[nomeata]

Oh, now I see pkgs/development/ocaml-modules/janestreet/janePackage_0_12.nix :-)

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
2. Ask on the NixOS Discourse.
3. Ask on the #nixos channel on irc.freenode.net.

This is still an issue with the janeStreet sub set.
