You can select a particular GHC version to compile with by setting the
`ghc` attribute as an argument to `buildStackProject`. Better yet, let
Stack choose what GHC version it wants based on the snapshot specified
in `stack.yaml` (only works with Stack >= 1.1.3):
{nixpkgs ? import <nixpkgs> { }, ghc ? nixpkgs.ghc}
with nixpkgs;
let R = pkgs.R.override { enableStrictBarrier = true; };
in
haskell.lib.buildStackProject {
name = "HaskellR";
buildInputs = [ R zeromq zlib ];
inherit ghc;
}
