# Choices

1. Install ghc 7.6.3 and Haskell Platform
2. Install ghc 7.8.4 and Cabal

# Option GHC 7.6.3 + Haskell Platform

## GHC 7.6.3

Install Ubuntu 12.04 depencies:

    $ sudo aptitude install -y libgmp3c2

Symlink the library:

    $ sudo ln -s /usr/lib/libgmp.so.3 /usr/lib/libgmp

Afterwards, download, configure, and install GHC.

    $ wget https://www.haskell.org/ghc/dist/7.6.3/ghc-7.6.3-x86_64-unknown-linux.tar.bz2
    $ tar xvf ghc-7.6.3-x86_64-unknown-linux.tar.bz2
    $ cd ghc-7.6.3
    $ ./configure --prefix=/opt/ghc
    $ make install      # sudo might be necessary

Add `/opt/ghc/bin` to `$PATH`.

## Haskell Platform 2013.2.0.0

Install Ubuntu 12.04 depencies:

    $ sudo aptitude install -y libgmp3-dev libglc-dev freeglut3 freeglut3-dev

Haskell Platform Ubuntu dependencies:

    $ wget http://lambda.haskell.org/platform/download/2013.2.0.0/haskell-platform-2013.2.0.0.tar.gz
    $ tar xvf haskell-platform-2013.2.0.0.tar.gz
    $ cd haskell-platform-2013.2.0.0
    $ ./configure --prefix=/opt/haskell-platform --enable-unsupported-ghc-version
    $ make -j4
    $ make install      # sudo might be necessary

Add `/opt/haskell-platform/bin` to `$PATH`.

## Cabal

Cabal is included as part of Haskell Platform. Go ahead and update it:

    $ cabal update && cabal install cabal-install

Some useful packages:

    $ cabal install ghc-mod hoogle hlint pointfree

# Option GHC 7.8.4 + Cabal

## GHC 7.8.4

You cannot currently build Haskell-Platform with 7.8.4, so ignore these build
instructions.

Install Ubuntu 12.04 depencies:

    $ sudo aptitude install -y libgmp3-dev

Afterwards, download, configure, and install GHC. This is for the x86_64
version. For the 32 bit version please download the appropriate source from
[here](https://www.haskell.org/ghc/download_ghc_7_8_4).

    $ wget https://www.haskell.org/ghc/dist/7.8.4/ghc-7.8.4-x86_64-unknown-linux-deb7.tar.xz
    $ tar xvf ghc-7.8.4-x86_64-unknown-linux-deb7.tar.xz
    $ cd ghc-7.8.4
    $ ./configure --prefix=/opt/ghc
    $ make install      # sudo might be necessary

Add `/opt/ghc/bin` to `$PATH`.

## Cabal

If you are running Ubuntu 12.04 AMD64 you can bootstrap cabal from this [binary
image][hvr].

Otherwise build it from source:

    $ wget http://www.haskell.org/cabal/release/cabal-1.18.1.3/Cabal-1.18.1.3.tar.gz
    $ tar xvf Cabal-1.18.1.3.tar.gz
    $ cd cabal-1.18.1.3
    $ ./bootstrap.sh --user

Update cabal:

    $ cabal update && cabal install cabal-install

Some useful packages:

    $ cabal install ghc-mod hoogle hlint pointfree
