Okay, I juste solved issue (1) : The package compiled through Cabal has its information stored in the dist/package.conf.inplace file. I can then compile my main by doing : ghc --make -package-conf dist/package.conf.inplace main.hs I just don't know if it's really the way I'm supposed to do this.
Nevertheless, issue (2) remains...
