An OS X build of GHC 7.10.1-rc3 is now available, courtesy of Mark Lentczner. This is in addition to the GHC 7.8.4 and 7.10.1-rc2 builds Mark has made available on February 2. Thanks, Mark. GHC 7.8.4 for OS X can already be downloaded from haskell.org, even though it’s not mentioned on the GHC 7.8.4 webpage: https://downloads.haskell.org/~ghc/7.8.4/ghc-7.8.4-x86_64-apple-darwin.tar.x... To avoid running up Mark’s bandwidth bill, I’m omitting the URL to his staging area. I’ve mirrored all three builds in Halcyon public storage: 7.8.4: https://halcyon.global.ssl.fastly.net/original/ghc-7.8.4-x86_64-apple-darwin... 7.10.1-rc2: https://halcyon.global.ssl.fastly.net/original/ghc-7.10.0.20150123-x86_64-ap... 7.10.1-rc3: https://halcyon.global.ssl.fastly.net/original/ghc-7.10.0.20150316-x86_64-ap... Binary builds of GHC, repackaged with documentation removed, are also available in Halcyon — on OS X 10.10, 10.9, 10.8, and a considerable number of Linux distributions. This includes GHC 7.10.1-rc3, 7.10.1-rc2, 7.8.4, 7.8.3, 7.8.2, 7.6.3, 7.6.1, 7.4.2, 7.2.2, and 7.0.4. Using Halcyon, installing GHC together with cabal-install is expected to take 20-30 seconds: https://halcyon.sh/tutorial/#install-ghc-and-cabal -- Miëtek https://mietek.io
