Hello,
This is more of a Haskell and Stack question than a Nix question, so I’m gonna post it here instead of NixOS discouse.
Recently, GHC 8.6.5 was dropped from nixpkgs master branch. I added it back via an overlay, but the problem is, stack refuses to use that particular instance of GHC 8.6.5 on NixOS.
Is there a way to force stack to use system ghc on NixOS while still using Nix for other packages?
