Subject: Re: Linking opengl under windows

Hello,

I've checked the situation of opengl module of ruby.

My patch for opengl module is not necessary for latest version of
rbogl (ver 0.32b).
Sorry for confusing you.

I downloaded binary package of glut v. 3.7.6 from 
http://www.xmission.com/~nate/glut.html
and compiled opengl.so and glut.so.

They works well in my system (Windows2000) with Ruby (v.1.6.5).

I also copied .h to vc98\include and .dll to windows(or winnt)\system.

I think these errors come from incompatibility of glut32.lib and other (.h 
or .dll?) files. (I encountered something like this when I loaded new glut 
module form Ruby without rebooting system.)

Good luck!
