Re: [arch-haskell] ghc: /usr/share/doc/ghc/html/libraries/hslogo-16.png exists in filesystem

From user's perspective, I guess I agree the Arch packages should be

Ramana, preferred. I'm new to Haskell, so I'm not able to comment on packaging strategies. I simply listen to what experts say, trying to make my own sense of it. -- Mateusz Łoskot (sent from mobile, apology for top-post or broken quotes) On 15 Oct 2012 17:22, "Ramana Kumar" wrote:

It is possible and desirable to manage haskell packages with pacman on Arch Linux! It is just not perfect yet - the arch-haskell project needs your help. Perhaps you could point Ian Ross this way too. (For me personally, using the [haskell] and [haskell-extra] repositories has worked out well so far, and it's nice knowing everything is managed properly by pacman.)

I'm not sure why that error happened but it happened to me too.

The problem seems to be that those files were not part of any package, but now are in ghc.

I removed the offending files manually and tried again, and ran into more problems (although everything installed, there were many warnings about interface files being the wrong version and being skipped). So I'm not sure what the correct way out is. Perhaps it will require some manual removals then reinstalls.

This is a problem with ghc-pkg version. For previous version of ghc I had to do:

$ pacman -Rcs ghc

then reinstall ghc and needed haskell-* packages. I think you'll want to remove the offending files before installing ghc again. I hope this solve the problem.

Why is it that every single time there is a ghc-update, I have to remove everything and reinstall everything haskell related. Haskell is such a cool language but keeping a Haskell environment up-to-date is sometimes just a real pain.

As Haskell newbie and new born Hakyll users, I've found recent replies [1] by Ian Ross interesting:

"I'm also using Arch Linux on x86_64. I would strongly recommend *not* using the Arch packages for most Haskell things. I use hsenv instead."

I haven't switched myself and I still use the packages, but I started to wonder if Ian's got the point indeed.
