[Haskell] Importing Repa library
Hello! :) I want to write a simple application, using the Repa library as a university project, but I don't know much about Haskell. I'm using Windows, so I downloaded and installed Haskell platform for Windows, then I run in the command prompt cabal update, then cabal install cabal-install and then cabal install repa and everything seemed fine. Then I put this script import qualified Data.Array.Repa as R :m +Data.Array.Repa Z into the file file.hs, opened WinGHCi and loaded the file, and then evaluated it, but what I get is: Could not find module `Data.Array.Repa' Perhaps you meant Data.Array.Base (from array-0.4.0.0) Data.Array.IO (from array-0.4.0.0) Data.Array.ST (from array-0.4.0.0) Use -v to see a list of the files searched for. Failed, modules loaded: none. I read that This happens when you install a package globally, and the previous packages were installed locally. Note that cabal-install install locally by default and the runhaskell Setup commands install globally by default., but I think that I installed Repa locally, not globally. Also ghc-pkg list repa says: WARNING: cache is out of date: C:/Program Files/Haskell Platform/2012.4.0.0\lib\package.conf.d\package.cache use 'ghc-pkg recache' to fix. C:/Program Files/Haskell Platform/2012.4.0.0\lib\package.conf.d: C:\Users\Faery\AppData\Roaming\ghc\i386mingw32-7.4.2\package.conf.d: And after executing recache, I get the same. Please help me to fix this issue and to be able to use the library. Thank you very much in advance for your time and goodness! ___ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
