Install Glasgow Haskell Compiler GHC on Ubuntu

Download GHC

http://www.haskell.org/ghc/download_ghc_7_4_2#x86linux 



This is the INSTALL instructions for a binary distribution of GHC. For
more details on what on earth this package is up to, please consult
the README and ANNOUNCE.

This distribution can be installed in a location of your choosing.

To set the ball rolling, run the configure script (as usual, run the
script with --help to see what options it supports).  eg. to set up
the package for installing in directory , use

    ./configure --prefix=

The default installation directory is /usr/local.

The configure script will figure out what platform you're running on,
and a couple of other interesting pieces of trivia, which it will then
fill in the Makefile.in template to give you a real Makefile.  If
you're of a paranoid persuasion, you might want to take a look at this
Makefile to see if the information is correct.

Now run:

    make install

(`make show-install-setup' prints the details of where the different
pieces of the bundle are heading when -- possibly helpful).

For more information, full GHC documentation is available from the
main GHC site:

  http://www.haskell.org/ghc

Bug reports/suggestions for improvement to the installation
procedure/setup (as well as other GHC related troubles you're
experiencing, of course), gratefully received.  Bug reporting
instructions are here:

Enjoy,
