the process that generates those IDs in GHC is non-deterministic. Two people can compile the same library with the same version of GHC on the same type of machine yet end up with two distinct IDs. It doesn't happen often, but it does happen. I'd recommend running $ nix-store --delete /nix/store/*-haskell-parsec-ghc7.8.3-3.1.5-shared on all your machines. Then the next build will download these packages from Hydra, and you'll have a consistent build again. Note that you may have to remove packages from your active profiles to make that deletion process succeed. I hope this helps, Peter _______________________________________________ nix-dev mailing list [email protected] http://lists.science.uu.nl/mailman/listinfo/nix-dev
