Hi Kirill, > nix-shell '<nixpkgs>' -A haskell-ng.compiler.ghc763
that command starts a shell with an environment set-up that can be used for building "haskell-ng.compiler.ghc763". This does include all dependencies of GHC 7.6.3, but not the compiler itself. > Whenever I have something like > > testHaskell = haskell-ng.packages.ghc784.ghcWithPackages (hp: []); > > in my `config.nix`, it starts to build ghc: ... But if I add any > single package to the list in `ghcWithPackages` it is no longer > building anything. I cannot re-produce that, I'm afraid. On my system, both attributes testHaskell1 = self.haskell-ng.packages.ghc784.ghcWithPackages (hp: []); testHaskell2 = self.haskell-ng.packages.ghc784.ghcWithPackages (hp: with hp; [mtl]); seem to work fine.
