cannot build using `stack`

Hi, i saw your blogpost from Tweag and i would love to create a updated version of the graph

Describe the bug The stack build command fails with the following error:

error:
       … while calling the 'derivationStrict' builtin

         at /builtin/derivation.nix:9:12: (source not available)

       Did you mean one of ghc943, ghc810, ghc88, ghc884 or ghc94?

Environment

OS name + version: NixOS 23.11.20240501.0638fe2 (Tapir)
Version of the code: Latest commit from master

Hi, glad you liked the blog post.

This is a limitation of Stack with Nixos: it can't download the compiler itself, so it relies on Nix. But if the precise Nix version isn't pinned (there's a pin for the Nix script in default.nix, but not for GHC), then Stack may require a version that isn't in Nixpkgs anymore.

The Haskell file is simple enough. You probably can fix the build by applying the following change to the stack.yaml file:

- resolver: lts-12.14
+ resolver: lts-22.6

- resolver: lts-12.14
+ resolver: lts-22.20

This repository is very much exposed “as is”, we aren't really spending time in maintaining it. That being said, you may want to sync up with the Nixtract team (@ErinvanderVeen , @GuillaumeDesforges ) who may have more modern ways of generating a similar graph.
