I'm a true beginner, so maybe what I say is false or useless, but from the few I know, I think the statement "import" is asking for the name of a module, not just the name of a file. So, is your file starting with the module declaration statement "module Powser (...) where" ? Le mardi 19 avril 2016, Doug McIlroy <doug@cs.dartmouth.edu> a écrit :
I have module Powser stored in haskell/Powser.hs. There is no file ./Powser*.
This loads the module shellprompt> ghci -ihaskell Prelude> :load Powser But this can't find it shellprompt> ghci -ihaskell Prelude> import Powser
What might cause the difference? (I am running ghci 7.8.4.)
