trying to run programs

[Johansson Mikael]

hello

I'm starting up using a GHC-compiler and have successfully compiled a =
simple
"Hello World" program. Thanks for the responses.
Now I'm trying to use some simple programs from haskell.org/hugs but =
there are
problems.=20

Compilation had errors

It seems some object are missing. I have tried to find them=20
in ghc/lib/imports and others but haven't succeded.
Is there some libraries I need to run these hugs-files on
my ghc-compiler?

regards
