Subject: [Haskell-beginners] Trying to install "Craft3e" from Hackage
using stack
Message-ID: <ners58$msg$1...@ger.gmane.org>

I'm currently reading "Haskell: the Craft of Functional Programming", by
Simon Thompson and I'm trying to download and install the package books
code.
But when I run "stack build Craft3e" I get the following error message:
> Run from outside a project, using implicit global project config
> Using resolver: lts-5.12 from implicit global project's config file: >
/home/dumbl3d0re/.stack/global-project/stack.yaml
> While constructing the BuildPlan the following exceptions were

> mtl: needed (>=1.1 && <2.2), 2.2.1 found (latest applicable is
2.1.3.1)
> needed for package Craft3e-0.1.0.10
How should I go about to install "Craft3e"?
Thanks in advance!
Regards,
Albin

Assuming that you would keep any book-related code in a local project,
here's how you'd create a local project with a dependency on Craft3e:
# Create a new project using ghc-7.8 (due to Craft3e's dependency on mtl <2.2)
$ stack --resolver ghc-7.8 new craft
$ cd craft
# Edit the library section of craft.cabal to contain a dependency on Craft3e:
#
# build-depends: base >= 4.7 && < 5
# , Craft3e
#
# Calculate a consistent set of packages to use in the project:
$ stack solver --update-config
Now you can write exercises etc. as library modules in the src
directory and use them interactively with stack repl.
If you haven't used stack before, you might also want to take a look
at the stack guide:
http://docs.haskellstack.org/en/stable/GUIDE/
Cheers,
Simon

I don't know if it's possible with the method you described, but I need
to be able to import some files into GHCi. They contain function
definitions that I have to be able to use in GHCi.
