You're using the msys version of python, which doesn't correctly search for the SO name. {{{ 6ef8:5d44 @ 584664718 - LdrLoadDll - ENTER: DLL name: kernel32. 6ef8:5d44 @ 584664718 - LdrpLoadDllInternal - ENTER: DLL name: kernel32 6ef8:5d44 @ 584664718 - LdrpFindKnownDll - ENTER: DLL name: kernel32 6ef8:5d44 @ 584664718 - LdrpFindKnownDll - RETURN: Status: 0xc0000135 6ef8:5d44 @ 584664718 - LdrpSearchPath - ENTER: DLL name: kernel32 6ef8:5d44 @ 584664718 - LdrpComputeLazyDllPath - INFO: DLL search path computed: E:\ghc- dev\msys64\usr\bin;C:\WINDOWS\SYSTEM32;C:\WINDOWS\system;C:\WINDOWS;.;E:\Program Files (x86)\Windows Kits\10\Debuggers\x64\winext\arcade;C:\ruby215\bin;C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\WIDCOMM\Bluetooth Software\;C:\Program Files\WIDCOMM\Bluetooth 6ef8:5d44 @ 584664718 - LdrpResolveDllName - ENTER: DLL name: E:\ghc- dev\msys64\usr\bin\kernel32 6ef8:5d44 @ 584664718 - LdrpResolveDllName - RETURN: Status: 0xc0000135 6ef8:5d44 @ 584664718 - LdrpResolveDllName - ENTER: DLL name: C:\WINDOWS\SYSTEM32\kernel32 6ef8:5d44 @ 584664718 - LdrpResolveDllName - RETURN: Status: 0xc0000135 6ef8:5d44 @ 584664718 - LdrpResolveDllName - ENTER: DLL name: C:\WINDOWS\system\kernel32 6ef8:5d44 @ 584664718 - LdrpResolveDllName - RETURN: Status: 0xc0000135 6ef8:5d44 @ 584664718 - LdrpResolveDllName - ENTER: DLL name: C:\WINDOWS\kernel32 }}} 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). correct the link from python3 -> mingw python3.5 and you should be good to go. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12661#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
