Create environments with GHC HEAD artefacts
The README says:
One simple way to use it is:
nix run -f https://github.com/mpickering/ghc-artefact-nix/archive/master.tar.gz ghcHEAD
This will enter a shell where the most up to date artefact built for the master branch is available to use.
This doesn't enter a shell anymore. Instead it calls the respective executable, so the command above will produce:
ghc: no input files
Usage: For basic information, try the `--help' option.
Whereas:
❯ nix run -f https://github.com/mpickering/ghc-artefact-nix/archive/master.tar.gz ghcHEAD -- --version
The Glorious Glasgow Haskell Compilation System, version 9.3.20220130
This is with
❯ nix --version
nix (Nix) 2.6.0pre20211217_6e6e998
but I also tried recent releases, and both 2.4 and 2.5 suffer from it. OTOH 2.3 works as currently described.
nix run -f https://github.com/mpickering/ghc-artefact-nix/archive/master.tar.gz ghcHEAD
warning: unable to download 'https://gitlab.haskell.org/ghc/ghc/-/jobs/artifacts/master/raw/ghc-x86_64-apple-darwin.tar.xz?job=validate-x86_64-darwin': HTTP error 404; using cached result
Builds of GHC master
commits including https://gitlab.haskell.org/ghc/ghc/-/merge_requests/6485 fail as ghc-cabal
now depends upon libstdc++
.
This could be useful for testing MRs.
Following the README, I try
~/build/haskell/ghc $ nix run -f https://github.com/mpickering/ghc-artefact-nix/archive/master.tar.gz ghcHEAD
[0.0 MiB DL]
error: unable to download 'https://gitlab.haskell.org/ghc/ghc/-/jobs/artifacts/master/raw/ghc-x86_64-fedora27-linux.tar.xz?job=validate-x86_64-linux-fedora27': HTTP error 404
(use '--show-trace' to show detailed location information)
but it fails. Is this a bug, or a transient, expected failure? If the latter, maybe point that out in the README, including possible ways to work-around that, and get a recentish GHC.
I've tried adding it myself to releases.nix
like this:
{ ghc_9_6_1_alpha1 = fromBindist {
url = "${downloads}/9.6.1-alpha1/ghc-9.6.0.20230111-x86_64-fedora33-linux.tar.xz";
sha256 = "sha256-bc+2Q2oPTe7eTJoaaVkE4w67A3XKvOzUp4DxDKlPYwI=";
};
}
But this complains about wrong GLIBC versions on NixOS 21.11:
$ nix run -f releases.nix ghc_9_6_1_alpha1 --extra-experimental-features nix-command
error: builder for '/nix/store/8fr0flad6x6949pfm0pqbafbvaq22vp7-ghc-9.6.0.20230111.drv' failed with exit code 2;

I've also tried the deb10
and deb11
bindists, but all fail with a similar error message.
@mpickering and I were discussing this on IRC: It seems that 633c6d7 is not sufficient to fix executable linking; there is still a dependency on libtinfo
sneaking in somehow. I suspect this is via the package database.

I'm using the derivation from this repository in another Nix shell derivation as:
{
pkgs ? import (fetchTarball https://github.com/NixOS/nixpkgs-channels/archive/nixos-20.03.tar.gz) {}
, ghcHeadOl ? import (fetchTarball https://github.com/mpickering/ghc-artefact-nix/archive/master.tar.gz) {}
, ghc ? ghcHeadOl.ghcHEAD
}:
with pkgs;
stdenv.mkDerivation {
name = "ghcenv";
buildInputs = [ ghc cabal-install ghcid ];
}
If I point my <nixpkgs>
to nixpkgs-unstable
or change np = import <nixpkgs> {};
to np = import (fetchTarball https://github.com/NixOS/nixpkgs-channels/archive/nixos-unstable.tar.gz) {};
in ghc-artefact-nix/default.nix
, the above Nix shell derivation fails with:
error: anonymous function at ghc-artefact-nix/artifact.nix:1:1
called without required argument 'llvm_39',
at /nix/store/dyca73pcc7d9zmmdnrcf35ycjg1gl4x6-source/lib/customisation.nix:69:16
I've fixed it by applying this patch to ghc-artefact-nix/default.nix
:
np = import <nixpkgs> {};
- ghc = self: ref: self.callPackage ./artifact.nix { } ref;
+ ghc = self: ref: self.callPackage ./artifact.nix { inherit (np.llvm_39) llvm_39; } ref;
I'm not making a pull request because this was a result of lot Googling and I don't fully understand what's going on here. It's working for me now but do you think ghc-artefact-nix/default.nix
needs to be patched?
