Re: [Haskell-cafe] Re: what does the hidden package error mean?

I agree, a better error message (or something less cryptic w.r.t. the new guy) would be very nice. --Deniz 2009/4/10 Anatoly Yakovenko :

Ah, bytestring was missing from the build-depends,

what a confusing error message, can we change it to say

"package Foo is missing from the MyPackage.cabal build-depends"

would be a lot more obvious how to fix it.

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

without any problems
