How to install recent ghc and cabal for ubunt 12.04 by adding ppa

Raw

install-recent-ghc.md

Add apt-repository, install ghc and cabal

I used this repository.

sudo add-apt-repository ppa:hvr/ghc
sudo apt-get install ghc-7.8.3
sudo apt-get install cabal-install-1.20

Add the bin directory to PATH

The packages install into /opt/ghc/$VER and /opt/cabal/$VER respectively. If you use zsh, make sure to add to bash settings as well. In Emacs haskell-mode, when hasekll-interactive-bring command tries to load ghci, the PATH envrionment seems to be under bash. Save the settings and test.

source .zshrc
source .bashrc
which ghci
which cabal
