Hi Sergey, > where can I find this ghc-wrapper ?
there are many versions of ghc-wrapper, one for every version of GHC that we support: $ nix-env -qaP \* | grep ghc-.*-wrapper haskellPackages_ghc6104.ghc ghc-6.10.4-wrapper haskellPackages_ghc6123.ghc ghc-6.12.3-wrapper haskellPackages_ghc704.ghc ghc-7.0.4-wrapper haskellPackages_ghc741_no_profiling.ghc ghc-7.4.1-wrapper haskellPackages.ghc ghc-7.4.1-wrapper haskellPackages_ghc741_profiling.ghc ghc-7.4.1-wrapper haskellPackages_ghc742.ghc ghc-7.4.2-wrapper The current default version is GHC 7.4.1, so you can install that one simply by running "nix-env -i ghc". Other versions can be selected by giving the full name, "nix-env -i ghc-6.10.4-wrapper", or by using the attribute path (which is what I personally prefer): $ nix-env -iA haskellPackages.ghc In short, if you want to use the Haskell 'split' library via Nix, you have to run $ nix-env -iA haskellPackages.ghc haskellPackages.split or $ nix-env -i ghc-7.4.1-wrapper haskell-split-ghc7.4.1 Take care, Peter _______________________________________________ nix-dev mailing list [email protected] http://lists.science.uu.nl/mailman/listinfo/nix-dev
