#751: Cabal confused about DeriveFunctor ---------------------------------+------------------------------------------ Reporter: osaunders | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: 6.12.3 Platform: Mac OS | ---------------------------------+------------------------------------------ Comment(by guest): I attached a patch to add DeriveFunctor, DeriveFoldable, and DeriveTraversable, but I don't know if I did everything necessary to add the extensions. In particular, the notes in Language.Haskell.Extension.hs say that new extensions should be added to the lists in Distribution.Simple.X.languageExtensions, but (at least for GHC) that seems to be generated dynamically. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/751#comment:1 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
