How to get it
~~~~~~~~~~~~~
The easy way is to go to the web page, which should be self-explanatory:
http://www.haskell.org/ghc/
Gentoo Linux users can get it from the gentoo-haskell overlay[1].
If you're not familiar with this overlay (a gold mine for haskell
hackers using gentoo), you can easily use layman[2] to get access. Make
sure you have darcs installed, as it is a requirement for our overlay.
Once layman is set up, add the overlay with:
$ layman -a haskell
Note that ghc-6.10.1 still is masked by keyword, and you need to unmask
it first. If you're not familiar with how to do this, here's a quick guide:
# make sure /etc/portage exists
$ [[ -d /etc/portage ]] || mkdir /etc/portage
# accept ghc being ~arch
$ echo "dev-lang/ghc" >> /etc/portage/package.keywords
# ghc requires the very latest libedit package
$ echo "dev-libs/libedit" >> /etc/portage/package.keywords
You may then install ghc-6.10.1 by saying:
# this requires that you already have an older ghc version installed
$ USE="ghcbootstrap -binary" emerge ghc
The USE flags are required as we don't just yet provide the required
binaries to bootstrap ghc. The command above requires that you already
have a ghc version installed to bootstrap with. This version will be
replaced with ghc-6.10.1 once the installation finishes.
GHC binaries will follow shortly, which will shorten the procedure to:
$ emerge ghc
The packages from extralibs will also be available from the overlay.
If you run into trouble, reply to the ml, or find us in #gentoo-haskell
at freenode.
Cheers,
