[Haskell-beginners] ghc-8.4.3 at Ubuntu

[Andreas Röhler]

Thanks all!

Will try hsenv.

Meanwhile recipe found here was succesful:

https://www.reddit.com/r/haskell/comments/5jsyr0/announce_ghc_802_release_candidate_2/

Did
sudo apt-add-repository ppa:hvr/ghc
sudo apt update
sudo apt install ghc-8.0.2 cabal-install-1.24

added /opt/ghc/bin to $PATH

Configure done so and make is running...
