#12661: Testsuite driver fails on Windows ---------------------------------+-------------------------------------- Reporter: bgamari | Owner: Phyx- Type: bug | Status: new Priority: normal | Milestone: Component: Test Suite | Version: 8.0.1 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+-------------------------------------- Changes (by Phyx-): * owner: => Phyx- Comment: I haven't encountered it before but: File not Found will also be returned by the system loader when it couldn't find a dependency of a library it's trying to load. In this case I suspect you've set up the buildbot on a completely new Windows install. In which case you're probably missing the proper Microsoft C Runtime. (Windows update would eventually get to this). According to the docs : https://docs.python.org/3.4/using/windows.html Python 3.5 has a dependency on the VC2015 runtime https://www.microsoft.com/en-us/download/details.aspx?id=48145 and Python 3.4 on the VC2008 runtime https://www.microsoft.com/en- us/download/details.aspx?id=15336 The load is probably failing because ctypes loads a dll that needs the runtime. It should have recorded the missing dependency in the Windows Event Viewer as well. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12661#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
