Hi all. My build fails, log: https://gist.github.com/elieux/2b2a074e03005f7754d6 I'm working on Windows x64, using msys2 with mingw64-x86_64 4.9.1. What I did: download the official 7.6.3 x64 build without included toolchain download x64 msys2, install x64 toolchain and set ghc to use it build Cabal, install Alex and Happy set paths to relevant binaries download http://www.haskell.org/ghc/dist/7.8.3/ghc-7.8.3-src.tar.xz extract cp mk/build.mk.sample mk/build.mk ./boot patch configure to remove the in-tree toolchain ./configure with some parameters make I have a PKGBUILD, but since I'm bootstrapping with the manually configured ghc, the environment is not 100% reproducible at the moment. Can you point me at what should I try changing to build successfully? -- David Macek
