We need to provide this information in a clear way, because this WILL be a problem where we'll have a support load from it (whether we want to or not, until GHC 7.8 gets a haskell platform release, this WILL happen. We need to have a mitigation strategy so that we aren't dealing with it constantly) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8197 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

(because GHC 7.6 doesn't know how to call clang correctly, because the CPP pass needs to be in clang's ASM CPP mode) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8197#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

This is going to be a nightmare for a lot of people once 10.9 hits, where Xcode 5 is required. I haven't tried Luke's script yet but it might be the right way to go. If we use it, we should ensure it's only called with clang is invoked via GHC, just to be on the safe side and to avoid causing any unforeseen problems for other clang users. Another alternative is to use apple-gcc42 until 7.8 ships. This is currently what I'm doing on 7.6.3 on 10.9/Xcode 5 and how it works if you install GHC 7.6.3 through homebrew. (apple-gcc42 installs a separate gcc-4.2 binary; it doesn't overwrite any existing gcc/clang stuff). Unfortunately both the wrapper and the apple-gcc42 approach are hacks. I would honestly be much more in favor of releasing a 7.6.4 that does a proper fix by backporting the clang compatibility patches. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8197#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
