I did better, to streamline the problems, I created a dedicated vm to keep things clean. So here is what I did:
1) I followed this guide http://fluffynukeit.com/series/haskell-nixos/ to establish ~/nixpkgs as my base for packages, adding this in my .zshrc: > rm -r ~/.nix-defexpr > ln -s ~/nixpkgs ~/.nix-defexpr > export NIX_PATH=/home/carlo:nixos-config=/etc/nixos/configuration.nix; 2) I installed ghc, cabalInstall and cabal2nix in my environment, with: > nix-env -iA haskellPackages.ghc > etc.. 3) I packaged software as usual in that guide. Now, look at the image of dependencies in "https://hackage.haskell.org/package/music-suite";. I installed without problems the packages music-pitch-literal and music-dynamics-literal, whose dependencies are all already packaged. I tested them in ghci, all fine. But when I went on packaging lilypond, it created a problem in my configuration, so that now ghc-pkg check reports errors in installed packages. Also, lilypond does not show up when I try to import it from ghci. Could you help me to point out the errors I'm doing here? 2014-12-02 18:54 GMT+01:00 Benno Fünfstück <[email protected]>: > Hi Carlo, > > can you try running nix-shell with --pure as an addiitional argument?
