How to install GHC on Ubuntu

#Install prerequisites

sudo aptitude install ghc darcs zlib1g-dev libncurses5-dev

#Get GHC 7.4.1 source and cabal-install HEAD

wget http://www.haskell.org/ghc/dist/7.4.1/ghc-7.4.1-src.tar.bz2

darcs get --lazy http://darcs.haskell.org/cabal/

tar xjf ghc-7.4.1-src.tar.bz2

cd ghc-7.4.1

./configure --prefix=$HOME/src/ghc

time make -j9 #Only took me about 19 minutes on recent quad core xeon

make install

echo "export PATH=`pwd`/bin:$HOME/.cabal/bin:$PATH" >> ~/.bashrc 

#my bashfu might be off here, but you get the idea

. ~/.bashrc

mv ~/.cabal ~/.cabalold

cd ../cabal/cabal-install

export EXTRA_CONFIGURE_OPTS="-p"

./bootstrap

cabal update

#Edit ~/.cabal/config to set library profiling to True

#Test everything up until now

ghc --version

cabal --version

#to pull your own 'haskell platform' try the following

cabal install haskell-src html mtl parallel parsec \

regex-base regex-compat regex-posix stm syb text \

transformers vector --solver=modular

#I had to leave out GLUT, OpenGL, fgl, QuickCheck, and cgi 

#to overcome some MonadCatchIO based dependency errors

 

 

 


                In order to get Pandoc and some of the other stuff I need try this



cabal install vector-strategies vector-fftw fgl graphviz
# In the future instead of the below I think I'll be able to do...
# cd ~/src
# cabal unpack pandoc-types
# cd pandoc-types
# Here I had to edit Text/Pandoc/Builder.hs to hide ((<>)) from Data.Monoid
cabal install pandoc Graphalyze

Also I need to email the maintainers of Graphalyze and gnuplot about the
 changes I had to make to get it to compile with GHC 7.4.1.
