Hello GHC users, Over the next few weeks Microsoft will be pushing out an update (the so-called Creators Update) to Windows 10 which will break the GCC toolchain shipped with all GHC releases prior to the yet-to-be-released 8.2.1 (see Trac [1] for details). Over the last few weeks our resident Windows expert Tamar and I have been working on preparing a set of patched Windows tarballs with retrofitted GCC toolchains covering GHC 7.2.1 through 8.0.2. These tarballs are now available on downloads.haskell.org. The new tarballs are distinguished from the original releases with a `-win10` suffix. For instance, the 64-bit 8.0.2 binary distribution can be found at, https://downloads.haskell.org/~ghc/8.0.2/ghc-8.0.2-x86_64-unknown-mingw32-wi... Other than an updated mingw/bin/gcc.exe, these are identical to the original releases. More details about the patched toolchain can be found in Tamar's ghc-compat repository [2]. As always, let me know if you encounter trouble. Finally, we should all thank Tamar for his work on this; without his effort GHC-on-Windows would be in a sad state indeed. Thanks Tamar! Cheers, - Ben [1] https://ghc.haskell.org/trac/ghc/ticket/13411 [2] https://github.com/Mistuke/ghc-compat
