[Haskell-fr] premier essai avec Parsec

[Marc Chantreux]

Bonjour a tous,

Je me suis lancé dans le tuto de DAAN LEIJEN sur parsec il y a qq temps.
Je voulais passer a l'experimentation mais je n'arrive pas a compiler
mon code.

J'ai tenté toutes les variantes de lancement de ghc fournies dans la le
tuto a coup de 

ghc -lparsec -Lparsec, 
ghc --package Parsec,
...

rien ne fait ... en simplifiant, voila ce que je tente: 

> cabal install 'parsec >= 3' 
Resolving dependencies...
No packages to be installed. All the requested packages are already
installed.
If you want to reinstall anyway then use the --reinstall flag.

> cat > a.hs 
import Parsec                    
main = print "do" 

> ghc -v !$
