To use the Eden compiler:
1. source the envars.sh shell script so you have the following aliases
 ghceden -- for the Eden compiler
 edentv  -- for Eden TV

$ source envars.sh

2. You need to install 2 packages for the example programs and need to initiate cabal
$ cabal update

Then edit the following lines in ~/.cabal/config

--with-compiler=
--with-hc-pkg=

to

with-compiler=/home/pt114/OPT/ghc-eden-7.6.1/bin/ghc
with-hc-pkg=/home/pt114/OPT/ghc-eden-7.6.1/bin/ghc-pkg

This points to the correct Eden compiler to use for the exercises.


3. Install the packages

$ cabal install edenskel
$ cabal install random
