Hi all, With the recent update to ghc 7.4 and the new haskell platform release, I found that only 2 packages on my system weren't happy with this change: - uhc - xmonad extras
For the time being, I kept them on ghc 7.0.4, so all is fine for now. I started looking into the problems a bit and found the XmonadExtras problem is a bit over my head, so I'll wait for upstream to fix it someday. However, UHC's problem seems simpler. It's just missing the 'binary' package, which got merged into ghc's core from 7.2.1 The way this is checked by the configure script is by just calling "ghc-pkg list --simple-output binary". I haven't investigated nix's cabal-hooking a lot, as it mostly "just works". I see it's using a little wrapper to point ghc to all installed packages, but my package list indeed doesn't show any core libraries (the ones inside the ghc derivation). Is this by design? If I remember correctly from before-nixos, ghc-pkg list did also show all built-in libraries (like containers and array). What should I do to have them show up? Or is there something against uhc's configure script's way of checking package availability that should be patched instead? Thanks, Mathijs
