Loading package OpenGL-2.2.1 ... linking ... done. Loading package GLUT-2.1.1 ... linking ... done.
The above message was after you have installed GLUT-2.0, but GHC was still loading GLUT-2.1.1. The later errors were caused by your forced copy of 2.0 lib over the default 2.1.1.
I noticed this myself. The problem is, I don't know where to get GLUT-2.1.1. If I look on Hackage [1] and select GLUT from the Graphics category, I am directed to GLUT-2.0. [1] http://hackage.haskell.org/packages/archive/pkg-list.html
the messages indicate that you already have GLUT-2.1.1 somewhere, even installed at some point. for the latest sources, http://www.haskell.org/haskellwiki/Opengl should give the correct pointers (btw, the hopengl mailinglist specifically covers these topics and, being low-traffic, has a better chance of reaching Sven, whenever he catches up with haskell-related email). in contrast to the hopengl home page, which is outdated, the link above is on the wiki, and is meant to collect information that usually puzzles new hopengl users. so if one of those who have successfully replaced glut with freeglut on windows (or other platforms) could add instructions to that page, that would be useful. from Ron's log, it appears that simply replacing the dll does not quite work? claus
