Right, so I see the problem...
You're using the msys version of python, which doesn't correctly search for the SO name.
Indeed it looks like that is the issue. Great catch!
it doesn't add the ".dll" to it. so the loader doesn't find it. What you want, is the mingw-w64 version of python (which is also compiled with GCC so MSVC runtime not needed).
{{{ pacman -S mingw-w64-$(uname -m)-python3 }}}
Odd, the installation of Sphinx should have installed it as well. It would be python3.5. The msys python is a bit broken (which is unsurprising, the msys versions are usually the bare minimum to get the msys shell itself working).
Judging from the output from that `pacman` command I suspect that the correct python was already installed. However...
correct the link from python3 -> mingw python3.5 and you should be good to go.
Ahh, I suspect this is what I missed. In fact, shouldn't it also be necessary to symlink `python` to `python3.5` as well to ensure that no references to the broken python leak through? This is a rather subtle step, do you think you could mention this on [[Building/Preparation/Windows]]? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12661#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
