Hi,

I get the following error while compiling (I guess it's actually the linking step):

$ghc -o cmimc cmimc.hs

ghc -o cmimc cmime.hs --make or ghc -o cmimc cmime.hs --package package-you-use

However, running the program with ghci: $ghci cmimc.hs Prelude Main> :set args "testinput.txt" Prelude Main> :trace main

gives the correct output...

Where might there be a problem? In my installation (Kubuntu i386, ghc6.10.4-1ubunbtu2) perhaps?

No. ghci/runhaskell automatically loades additional libraries. ghc do not.

Please tell me if/which additional info I need to provide.

TIA,

Erik
