Haskell ecosystem on Windows XP

leave a comment »

It’s been fun watching the Haskell ecosystem evolve into a mature system over the years. Seems that about every three months it takes a leap forward and I usually find myself uninstalling what I previously had and putting the latest and greatest on my laptop. To save myself some time in the future, I’ve compiled this post as a reference of basic “stuff” that is good to have for doing Haskell development on a Windows XP machine.

Haskell Platform

It used to be that you had to go find a number of different applications to get packages, compile source code and generate documents (among a handful of other things), then a group of folks identified an opportunity and put together a platform for getting new users a place to start. The result is the Haskell Platform.

After installing, you’ll want to go to the command line and run the following commands to make sure that you’ve got the latest version of Cabal and to make sure that it has the latest package list:

C:\cabal install cabal-install
C:\cabal update


Many developers are probably used to having a quality Integrated Development Environment (IDE) to work with and the Haskell Community’s answer is Leksah. Leksah is still fairly green and has a ways to go before being comparable to Eclipse or Visual Studio, but nonetheless, Leksah is packed with plenty of goodies that will make for easy development of packages and modules for distribution on Cabal.

It is best to use the installer from the Leksah website. Once you’ve installed the latest, you’ll need to run the following from the command-line

C:\ghc-pkg recache 

So that the packages on the system (those provided by GHC) will show up when you have the browse pane open.


If you plan on doing any Graphical User Interfaces (GUIs), then you’ll want to get the Haskell binding to the GTK+ library. On the page there should be an “All-in-one bundle”- for the purpose of the following, I went with version 2.20.

After extracting the bundle on the machine, make sure that the path you extracted the bundle at along with the child bin directory is added to the PATH environment variable.

Then from the command-line run the following and you should be able to include GTK in your project:

C:\cabal install gtk


I’ve been working on some basic game programming and I’ve done some stuff in the past with OpenGL so I decided to give the Haskell bindings a try. Windows doesn’t natively ship with the OpenGL library, so you’ll need to get it from here.

Then get the following packages off of Cabal:

c:\cabal install glut
C:\cabal install opengl


I haven’t done a dry run to test all of the above, so if you follow all of the above and come across a problem, post the solution in the comments. I’ll continue to update this post as I identify any problems or come across additional “stuff” that falls into the must-have category.
