Any news on this front? I've been trying to follow the cross compiling tutorial with no success at all, but I'm not actually sure if I'm just missing something simple (reading the .nix files even gives me the impression that the pkgs attribute when importing haskell.nix is ignored?).

I think the way you should do it is:

nix-build -A projectCross.musl64.hsPkgs.bench.components.exes.bench

with a "stock" default.nix file – the resulting value should a be a call to haskell-nix.project

See this for more details: https://input-output-hk.github.io/haskell.nix/tutorials/getting-started/#working-with-a-project
