I assume you're using cabal, which hides all packages by default. Add "bytestring" or "bytestring >= 0.9.*" or something along those lines to Build-Depends in your .cabal file. If you're not using cabal, I'm not sure why it would be hidden, but you can unhide with -package bytestring to GHC. -Ross On Apr 10, 2009, at 4:36 PM, Anatoly Yakovenko wrote:
I am trying to build ParseP on the latest ghc, and i am getting this error:
Text/ParserCombinators/ParseP/Interface.hs:26:17: Could not find module `Data.ByteString.Char8': it is a member of package bytestring-0.9.1.4, which is hidden
what does "hidden" mean? why does this work in ghci
import Data.ByteString import Data.ByteString.Char8
