Nixpkgs: Please backport ghc-8.8.3 into release-19.03

Created on 12 Apr 2020  路  13Comments  路  Source: NixOS/nixpkgs

Describe the bug
I installed ghc and stack using NixOS 19.09. When I try to use stack, it looks for GHC 8.8.3. However, the version of ghc installed is 8.6.5.

To Reproduce
Steps to reproduce the behavior:

  1. Use NixOS v19.09.
  2. Include ghc and stack in packages list.
  3. nixos-rebuild switch --upgrade
  4. stack new helloworld new-template

Expected behavior
A new project called "helloworld" should be created.

Screenshots

$ stack new helloworld new-template
error: attribute 'ghc883' missing, at (string):1:43
(use '--show-trace' to show detailed location information)

Additional context
Possibly related to #21470?

The problem here is that the derivation for GHC-8.8.3 just hasn't been backported to 19.09.

GHC-8.8.3 is available on both 20.03 and unstable:

Please feel free to open up a PR backporting ghc883 to the 19.09 release.

Your other option is to use an older stackage resolver that uses ghc882 or ghc865. I think LTS-15.1 or so uses ghc882 instead of ghc883. Also, LTS-14 uses ghc865.

Note: I've upgraded to 20.03 now, and deleted ~/.stack, but the bug persists.

I don't think using a different stackage resolver could help this particular problem. This error occurs when creating a brand new project, before you create the yaml files that would specify which resolver to use. I believe it's looking for ghc883 to run Stack itself.

@mhwombat Hmm, I'm not able to reproduce this locally.

My guess is that your 20.03 checkout is just too old? Can you try running sudo nix-channel --update and trying again?

On my 19.09 system, stack can't find ghc883 and I get a similar error to you:

$ stack new amy --verbose --resolver lts-15.8

However, if I explicitly use the latest 20.03 channel, it works:

Also, make sure you pass stack the --verbose flag.

You'll get a log message about how exactly stack is trying to run nix-shell. This is really helpful in debugging what is going on.

For example, in one of my commands above, I got the following message:

Run process: /run/current-system/sw/bin/nix-shell -E "with (import <nixpkgs> {}); let inputs = [haskell.compiler.ghc883 git gcc gmp]; libPath = lib.makeLibraryPath inputs; stackExtraArgs = lib.concatMap (pkg: [ ''--extra-lib-dirs=${lib.getLib pkg}/lib'' ''--extra-include-dirs=${lib.getDev pkg}/include'' ]) inputs; in runCommand ''myEnv'' { buildInputs = lib.optional stdenv.isLinux glibcLocales ++ inputs; STACK_PLATFORM_VARIANT=''nix''; STACK_IN_NIX_SHELL=1; LD_LIBRARY_PATH = libPath;STACK_IN_NIX_EXTRA_ARGS = stackExtraArgs; LANG=\"en_US.UTF-8\";} \"\"" --run "'/nix/store/6lzdpxshx78281vy056lbk553ijsdr44-stack-2.1.3.1/bin/stack' $STACK_IN_NIX_EXTRA_ARGS '--internal-re-exec-version=2.1.3.1' 'new' 'amy' '--verbose' '--resolver' 'lts-15.8'"

You can see exactly what arguments stack is passing to nix-shell.

TL;DR: Adding --nix-path nixpkgs=channel:nixos-20.03 as suggested by @cdepillabout solves the problem. Thank you!

is there any way to fix this without having to switch to nixos 20?

Mateiadrielrafael picture Mateiadrielrafael on 16 Apr 2020

is there any way to fix this without having to switch to nixos 20?

Yes, you can use @mpickering's NUR repository that contains all GHC versions.

Setup NUR as described on https://github.com/nix-community/NUR.

Then put the following into a shell.nix file next to your stack.yaml (replace GHC version as indicated in the comment):

with (import <nixpkgs> {});
let
  # Needs NUR from https://github.com/nix-community/NUR
  ghc = nur.repos.mpickering.ghc.ghc863; # Keep in sync with the GHC version defined by stack.yaml!
in
  haskell.lib.buildStackProject {
    inherit ghc;
    name = "myEnv";
    # Put compile-time system depenencies of your project in here:
    nativeBuildInputs = [ ];
    # Put run-time system depenencies of your project in here:
    buildInputs = [ ];
  }

@mhwombat

is there any way to fix this without having to switch to nixos 20?

@nh2's suggestion is what most people do. Use a shell.nix file for stack. There are directions in the Stack documentation about how to do this.

The other solution is just to open a PR backporting ghc883 to the to 19.09 branch. This would help the most people in the Nix community.

If you're not sure how to do this, the easiest thing would be to look for a PR adding ghc883 to the master branch, and then do that same thing but to the release-19.09 branch.

If you send this PR, I'll merge it in.

@cdepillabout @nh2 thanks for the suggestions

So, it's my first time using stack so I just wanted to create a project with stack new, so I don't have any version declared in my config.

I have acces to NUR and I'll try adding the needed ghcs from there to my overlay, but I don't really get how stack can't find version 8.8.3 when I have 8.8.3 as my global ghc version (installed from the unstable channel)

Mateiadrielrafael picture Mateiadrielrafael on 17 Apr 2020

I will look into opening a PR

@cdepillabout

So would opening a copy of this: https://github.com/NixOS/nixpkgs/pull/80975 into the 19.09 branch do the job?

Mateiadrielrafael picture Mateiadrielrafael on 17 Apr 2020

@Mateiadrielrafael Yes, that should hopefully work!

cdepillabout picture cdepillabout on 17 Apr 2020

I believe the issue has been resolved insofar as that we know what's causing it and how it can be fixed. My understanding is that @Mateiadrielrafael will submit an appropriate PR. Until then, I'll close this bug.
