Hi Athan, am I guessing correctly that your system follows the release-14.04 branch? If that is the case, then you should probably add the argument
-I nixpkgs=/opt/nixpkgs to the "nix-build" command-line to fix the build. The master branch contains code that allows it to build Haskell projects that contain no Setup.hs file [1], but patch code was never merged to release-14.04. (Not sure whether it should have been.) "nix-build default.nix" uses the system-wide nixpkgs repository (a.k.a. '<nixpkgs>'). Your call to nix-repl, however, loads another repository, which I suspect follows the master branch. I hope this helps, Peter [1] https://github.com/NixOS/nixpkgs/commit/dc285e6895e97355f769fdd6341b3e9c0cce2cf9 _______________________________________________ nix-dev mailing list [email protected] http://lists.science.uu.nl/mailman/listinfo/nix-dev
