Preparation for the workshop

Please bring your laptop with the following software pre-installed to the workshop.

macOS

If you are on macOS High Sierra (10.13) or Sierra (10.12), please download Haskell for Mac and activate the 14 day trial. Haskell for Mac is an IDE that makes it easy to get started with Haskell. You will receive a full license key at the workshop.

If you are on a version of macOS older than 10.12, please install the Haskell Platform (8.0.2) package. This provides you with a command line compiler.

Windows

Please install the Haskell Platform (8.0.2). (There is also a 32bit version.)

Linux

Please download the Haskell Platform (8.0.2). (There is also a 32bit version.)

Install by running:

$ tar xf ...downloaded archive...
$ sudo ./install-haskell-platform.sh

If you have a system with position independent executables by default (such as Ubuntu 16.10 and above), you should edit the GHC settings file at

usr/local/haskell/ghc-8.0.2/lib/ghc-8.0.2/settings

and change the "compiler supports -no-pie" flag from "NO" to "YES". (This is relative to your installation location.)

Alternatively, you can use your distribution's package manger to install version 8.0.2 of the haskell-platform package.

Editor support (optional)

Here are some optional suggestions for improved Haskell support in a variety of editors. You will be able to follow the workshop without installing any of these.
