Hi! the ghc compiler keeps complaing " can't find module 'Char', perhaps you haven't installed the profiling libraries for package haskell98?". but actually I did install it, and i checked with ghc -v , it is right there: "wired-in package haskell98 mapped to haskell98-1.0.1.0", and Char.hi is right there in the folder haskell98-1.0.1.0.. can't figure out why it happened.. anyone please ? Thanks! Liang --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo! Mobile. Try it now.

You'd want the hierarchical modules now. Replace import Char with import Data.Char and it should work.

Could you just use Data.Char instead?

On second reading, ghc asks for profiling libraries for haskell98, that would mean you should look for Char.p_hi. If there are no *.p_hi files in the folder, that library wasn't built for profiling and you should do that then, runghc ./Setup.hs configure -p runghc ./Setup.hs build runghc ./Setup.hs haddock runghc ./Setup.hs install Hope this helps, Daniel
Thanks! It is a very helpful hint..
I didnot find the profiling library for ghc-6.8.2, so I installed ghc661-prof, but the yum ( i use fedora 8) installed the latest ghc-6.8.2, so they end up in different directories..
now it is working.
Cheers,
