__NoChroot error trying to integrate stack build into NixOS configuration.nix

[cdepillabout]

To get past your immediate error, you can use the Nix option --option sandbox relaxed. This turns off the sandboxing for your Stack build.

Although, most people using Haskell with Nix don’t use the generic stack builder from Nixpkgs. One of the main reasons is the requirement that you turn off sandboxing!

So what are your options for building Haskell projects with Nix? I have a small list here:

Super-Simple Haskell Development with Nix

the simplest, most beginner-friendly approach to developing Haskell under Nix I think what you have here probably is the easiest approach to getting started with Nix + Haskell. For other people reading this, there are a couple other approaches to developing Haskell under Nix that you may want to consider: Use Nix to get GHC, cabal, and system deps. Then use cabal to download and build all Haskell dependencies: $ nix-shell -p haskell.compiler.ghc8104 -p cabal-instal -p zlib # zlib here i…

If you absolutely want to build a stack-based project with Nix, you have three main options:

1. Pick a version of Nixpkgs that uses the same LTS version your project is based on, and then use haskellPackages.developPackage or haskellPackages.shellFor for building your project.

2. Use haskell.nix. This has very good support for building from a stack.yaml file. The downside is that it can be quite complex.

3. Use stacklock2nix. This is a little simpler than haskell.nix (although I’d hesitate to say that it is “beginner-oriented”).
