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 !$
