I built the haskell platform as stated on the haskell package site.
After make install
I was told the files were installed to /usr/local/bin
How do I run the haskell platform after this step?
Haskell has to be started with ghci
command.
Visit HaskellWiki and see.
Also refer this Stackoverflow question.
You can run a Haskell by:
runhaskell [FILENAME].hs
Or
ghc [FILENAME].hs
