Hi Arie, My guess is that you don't have a necessary library in your path. Here are the Haskell libraries I have in my path (change as necessary for your setup): C:\Program Files\Haskell Platform\2013.2.0.0\lib\extralibs\bin C:\Program Files\Haskell Platform\2013.2.0.0\bin C:\Program Files\Haskell Platform\2013.2.0.0\mingw\bin HTH, Howard ------------------------- Message: 2 Date: Tue, 8 Oct 2013 18:12:41 +0200 From: Arie van Wingerden <xapwing@gmail.com> To: beginners@haskell.org Subject: [Haskell-beginners] Error when starting GHCI Message-ID: <CADkALSHpG7s89tT7rXJw56q7hkDyEcwv1=xu5Tg3_qLqoqtDxg@mail.gmail.com> Content-Type: text/plain; charset="iso-8859-1" Hi, today I downloaded the Haskell platform for 32 bits Windows (HaskellPlatform-2013.2.0.0-setup.exe) and installed it. The first time I started GHCI all worked perfectly. When I closed GHCI and later tried to start it again I constantly get however: C:\Users\Arie>ghci GHCi, version 7.6.3: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... ghc.exe: : Kan opgegeven module niet vinden. <command line>: can't load .so/.DLL for: (addDLL: could not load DLL) WHERE Kan opgegeven module niet vinden MEANS Can't find the specified module Any ideas? Kind regards, Arie
