Installing Hakyll on Gentoo Linux

Posted on June 28, 2015

I have been using Gentoo Linux as my primary OS since 2004. So, it usually important for me to choose software which available in Gentoo portage. And there is no Hakyll in portage :(

Of course, it is possible to install Hakyll from cabal using cabal-install, but according to the wiki this is not recommended. Instead of this, we can install this package fro the Gentoo Haskell overlay. So, first of all it required to add this overlay using layman (of course if you didn’t do it before).

$ emerge layman
$ layman -a haskell
$ echo "/var/lib/layman/make.conf" >> /etc/portage/make.conf

The next problem is that Hakyll requires Pandoc version >= 1.14 (which is also available in the overlay), and it has dependency on GHC >= 7.8. And this means that you have to unmask lot of packages. Bad news: autounmasking doesn’t work. Lot of packages should be unmasked manually to avoid blocking. Good news: I’ve done that and here is the list of unmasked packages:

You might have a trouble with blocking if you already have installed GHC. In this case you should emerge -uD ghc and then call haskell-updater --upgrade before emerging Hakyll.

Now you can create your own Hakyll based site.
