Subject: [Haskell-beginners] latest Haskell Platform build fails
Message-ID: <[email protected]>
Content-Type: text/plain; charset=utf-8; format=flowed
Hello all,
I am trying to install the latest version of Haskell Platform and am
having a problem.
I created a new VM and installed Ubuntu 14.04 server and applied the
latest updates. Also installed packages
"build-essential" and "zlib1g-dev".
I then downloaded and installed ghc-7.8.3 from
https://www.haskell.org/ghc/download_ghc_7_8_3#x86_64linux
and then downloaded and installed cabal 1.20.0.3 from
http://hackage.haskell.org/package/cabal-install.
After installing cabal, I did a "cabal update" followed by "cabal
install hscolour".
Then downloaded the latest Haskell Platform tarball
(haskell-platform-2014.2.0.0-srcdist.tar.gz) and attempted to
install like this:
./platform.sh ../ghc-7.8.3-x86_64-unknown-linux-deb7.tar.bz2
This fails like this:
***

Any suggestions on how to get past this?
Thanks,
