Subject: [Haskell-beginners] Problems with cabal install hakyll
Message-ID: <87zjq98h0s....@brittoffice.uwaterloo.ca>
Content-Type: text/plain
I have a fresh installation of ghc 7.6.3-1 and cabal 1.16. From this I
was able to cabal update and then cabal install diagrams and pandoc, but
when trying to install hakyll (either version 4 or 3) I get a lot of
dependency conflicts. Can anyone give me some suggestions on how to
proceed in this case? Thank you. Below follow the messages from
cabal install --dry-run

Hi Britt,
most likely the problem is solved by using a cabal sandbox (cabal >= 1.18).
Update your cabal version:
cabal install cabal-install
Create a sandbox and build hakyll in it:
cabal sandbox init
cabal install -j hakyll (-j for building on multiple cores)
The hakyll binary will then be located in './cabal-sandbox/bin/'.
Greetings,
Daniel

Thanks for the suggestion, but cabal 1.18 has conflicts with gtk2hs. In an
earlier post to the beginners list, I was instructed to roll back to 1.16 to
get around a conflict with gtk2hs.

Than perhaps installing diagrams, pandoc and hakyll at once might work,
so that cabal might be able to select versions fitting all three:
cabal install diagrams pandoc hakyll
You might need to delete your '~/.cabal' and '~/.ghc' directories
to get this working, or for testing, just rename them.
Greetings,
Daniel

Thanks for the advice. I deleted my ~/.cabal and ~/.ghc and then
installed hakyll first followed by diagrams and everything was fine.

Okay, I solved the exact test case the paper proposed.
Now I've hit another problem:
> -- -- -- stupid loop
> -- `runSP loop_swap [1..10]` works
> loop_swap :: SP a a
> loop_swap = let swap (a, b) = (b, a) in loop (arr swap)
> -- loop_bufid is just a "delayed id"
> -- `runSP loop_bufid [1..10]` doesn't works :(
> loop_bufid :: SP a a
> loop_bufid = loop (Get (\a -> Get (\b -> Put a (Put b id))))

At least I'm doing progress. :)

Another solution would have been to resort to pre-1.18 means by using
hsenv, for example.
