Hi Paul, Grep nixpkgs for "$out/nix-support/propagated-user-env-packages".
That's the way to tell nix-env to install additional packages to cabal into your environment. An alternative is this approach which let's you install multiple packages using one derivation only: http://wiki.nixos.org/wiki/Howto_keep_multiple_packages_up_to_date_at_once I also encourage you having a look at hack-nix which is a cabal replacement based on nix creating local environments for each working directory based on your configuration. Dependency resolution is done by brute force. So currently it does not make sense to support all possible combinations. I can help you getting started if you're interested in it. It also generates tag files on the fly. Marc Weber _______________________________________________ nix-dev mailing list [email protected] https://mail.cs.uu.nl/mailman/listinfo/nix-dev
