Thanks Ben. I installed the Mac binaries. For others who are wondering, you need llvm 5 if you want to use llvm with this.
Needless to say, many libraries, e.g. haskell-src-exts, primitive, and intero won't compile with this even with --allow-newer I'll notify those libraries about that in case they want to get started on 8.4.1 Cheers George On Wed, Dec 20, 2017 at 4:48 PM Ben Gamari <b...@well-typed.com> wrote: > > The GHC development team is pleased to announce the first alpha release > of the 8.4.1 release.
