I spent many hours getting Haskell-IDE-Integration working with ghc-863 (lts-13.10). The Haskell IDE Integration package actually will not compile without this version. I see the package is available as ghc863Binary, but not as tag ghc863. Further, when I install the ghc863Binary tag, it installs, but is not recognized by the Haskell Nix integration, which is specifically looking for the tag ‘ghc863’. I have rolled back my generation to get back off of 864, which sort-of works, but error persists:
stack repl error: attribute 'ghc863' missing, at (string):1:48 (use '--show-trace' to show detailed location information)
I’m trying to figure out whether I should file a bug report somewhere or if this is something I can still fix. Thanks.
