cannot work with ghc 8.10: Test suite pretty-simple-doctest: FAIL

[7c78]

Hi. I use your template https://github.com/srid/haskell-multi-nix and get an error

Here is my flake.nix

{
    inputs = {
        nixpkgs.url = "github:nixos/nixpkgs/nixpkgs-unstable";
        flake-parts.url = "github:hercules-ci/flake-parts";
        haskell-flake.url = "github:srid/haskell-flake";
        systems.url = "github:nix-systems/default";
        flake-root.url = "github:srid/flake-root";
        mission-control.url = "github:Platonic-Systems/mission-control";
    };

    outputs = inputs:
        inputs.flake-parts.lib.mkFlake { inherit inputs; } {
            systems = import inputs.systems;
            imports = [
                inputs.haskell-flake.flakeModule
                inputs.flake-root.flakeModule
                inputs.mission-control.flakeModule
            ];
            perSystem = { self', inputs', system, lib, config, pkgs, ... }: {

                haskellProjects.hello1 = {
                    basePackages = pkgs.haskell.packages.ghc8107;
                };
                haskellProjects.hello2 = {
                };

                devShells.default = pkgs.mkShell {
                    inputsFrom = [
                        config.flake-root.devShell
                        config.mission-control.devShell
                    ];
                };
            };
        };
}

If I run nix develop .#hello2, the shell is built OK and the ghc version is 9.2.7. But if I run nix develop .#hello1, it runs very long and eventually I get the following error

error: builder for '/nix/store/fw26751xhsn8x6891pa6rl6fqd6kal8r-pretty-simple-4.1.2.0.drv' failed with exit code 1;

How can I fix that? Thanks.

You need to override the failing packages: https://haskell.flake.page/dependency

In this case, pretty-simple = pkgs.haskell.lib.dontCheck super.pretty-simple.

Example: https://github.com/nammayatri/common/blob/3ba4249bbd4bc81233502f504f5b8e0924d79911/nix/ghc810.nix#L66-L102

How can not install all packages?

What do you mean?

[7c78]

Sorry, please don't mind.

I meant I just want to create a devshell like this

               devShells.hello = pkgs.mkShell {
                    packages = with pkgs; [
                        haskell.compiler.ghc810
                        cabal-install
                        ghcid
                    ];
                    inputsFrom = [
                        config.flake-root.devShell
                        config.mission-control.devShell
                    ];
                };

What you have should work if you don't have any local packages to compile.

[7c78]

Do you mean I need to use buildInputs instead of packages if I have local packages?

[srid]

I'm referring to local Haskell packages to compile. I don't really understand what you are asking; maybe it would help if you shared your actual project code (full repo), with a clear statement of what you are trying to achieve.
