Just to add to Carter's message: if you happened to install Xcode 5 anyway, then realized your mistake and uninstalled it and installed Xcode 4 again, you will STILL have the command line tools that came with Xcode 5 and your Haskell toolchain will STILL be broken -- and so far I have been unable to fix that by any combination of cabal's "gcc-location", ghc's "-pgmP", and various other options. This was true even though I installed the command line tools that came with Xcode 4.
Eventually I fixed this by manually installing the command line tools separately from https://developer.apple.com/downloads/index.action?=command%20line%20tools# Unlike ticking the "Command line tools" option in Xcode itself, this will actually overwrite the command line tools in /usr/bin, and my Haskell toolchain was once again restored. I don't know why I couldn't get it to work by pointing to the relevant tools in /Applications/Xcode.app/Contents/Developer/usr/bin, but there you go.. Anyway, this might save some of you some headaches.. -Edsko On Fri, Sep 20, 2013 at 7:05 PM, Carter Schonwald <carter.schonw...@gmail.com> wrote: > glad to help. > > an alternative for the discerning power user is to install a recent version > of gcc locally (eg 4.8), and build 7.6.3 with that!
