Haskell Graphics

The next step in my Haskell quest has been to display some graphics. I might add that I use windows and that I use Haskell platform 2012.2.0.0. After a bit of investigation I found this rather hairy description. Not too encouraging. At this point I had been fiddling around and I might have installed bindings for OpenGL and GLUT using cabal.

(?) cabal install OpenGL

(?) cabal install GLUT

At least the packages are among my installed packages when listing using

cabal list –installed

 

Anyhow, I decided to just give it a shot without installing anything – just to see what happened. I copied the source code for teapot.hs and compiled it using:

ghc teapot.hs

 

It actually compiled without any problems into teapot.exe but when run nothing happened. I figured that this might be due to a missing glut32.dll. I downloaded a precompiled version from here and placed the dll next to the teapot.exe and bang:

The application was up and running. Nice and simple. (Don’t know why it is called teapot though).
