cabal2nix broken on darwin

[MaxDaten]

I'm fairly new to nix, not sure if it the right place. I did a fresh install of nix via curl https://nixos.org/nix/install | sh.

And then right after the (single-user) installation, I did nix-env -i cabal2nix, and it fails with:

Any ideas how to solve this?

[peti]

Personally, I have no idea what those errors mean. Pinging @shlevy and @domenkozar, who might be able to help. In any case, this bug is probably better reported at https://github.com/nixos/nixpkgs since it doesn't look like it's related to cabal2nix itself.

[domenkozar]

Most probably needs a bump of swift-corefoundation-private.

[wildsebastian]

We discussed the issue on the nix-darwin irc yesterday. This should be fixed by #49768. It not only happens on the latest beta of macOS, but also 10.13 as well as the stable 10.14 and 10.14.1.

[MaxDaten]

Okay, thanks for the clarification and moving the issue to the correct place. I will try the fix as soon it landed.

[pshemass]

I'm interested in fix for that however I don't really have enough knowledge about Nix to know what is the process of release fixes like that.
I see that PR been merged but what next? should this be available in unstable channel already?

Let's find out together ;) I'm a completly novice to the nix eco-system, but I found some parts:

1. http://howoldis.herokuapp.com/ You can see here, how old the corresponding channels are. For example nixpkgs-unstable is currently 2 hours ago. What does this mean? Let's investigate and click the channel.
2. https://releases.nixos.org/nixpkgs/nixpkgs-19.03pre158299.efe6322ce4c You can see the git commit the channel is based on and the corresponding hydra evaluation
3. https://hydra.nixos.org/eval/1488172 Here you see the evaluation of the current channel version. What does this mean? Hydra is building packages continuously based on new git commits and this will update channels regularly. (not sure about the rules when exactly, but there are some test matrices)
4. When search for cabal2nix, I will recieve following for the current nixpkg-unstable channel evaluation: https://hydra.nixos.org/eval/1488172?filter=cabal2nix&compare=1488136&full=#tabs-still-succeed

So I assume it should be possible to install cabal2nix (because hydra was able to build it successfully). But maybe hydra differs in the macOS version.

I did following:

$ nix-channel --list
nixpkgs-unstable
$ nix-channel --update
$ nix-env -i cabal2nix

But this was unsuccessful on my machine.

I'm currently still in the build progress of:

$ nix-env -iA 'nixpkgs.haskellPackages.cabal2nix'

Not sure what the exact difference between cabal2nix and nixpkgs.haskellPackages.cabal2nix is.

After clicking here https://hydra.nixos.org/build/83848234 hydra offers a possibility to install from binary cache:

nix-env -i /nix/store/ksasgf87kk7289hx4k6fs8xm3n51l0r2-cabal2nix-2.11.1 --option binary-caches https://cache.nixos.org

I will try this next.

[pshemass]

it's already in unstable channel.

[LnL7]

@MaxDaten The output of nix-channel --list isn't complete. But if you named the channel nixpkgs-unstable you then have to use that as the prefix.

$ nix-env -iA nixpkgs-unstable.cabal2nix

And with this you can query the current version of channels on your system.

$ nix-env -p ~/.nix-defexpr/channels -q
nixpkgs-unstable-19.03pre159144.0249f7d48af
$ nix-env -p /nix/var/nix/profiles/per-user/root/channels -q  # only for multi-user
nixos-18.09.1228.a4c4cbb613c

Hi,

currently still problems:

$ nix-channel --list                                                                                                                                                                                                
nixpkgs https://nixos.org/channels/nixpkgs-unstable
$ nix-channel --update
$ nix-env -p ~/.nix-defexpr/channels -q                                                                                                                                                                             
nixpkgs-19.03pre159739.3ae0407d3c9

and calling:

$ nix-env -iA nixpkgs.cabal2nix
