Just for some background, here on Debian Etch I can apt-get install libopengl-ruby (the package which supplies ruby-opengl: http://www2.giganet.net/~yoshi/ ). To install it, it pulls in freeglut3 also. It gives you opengl.so and glut.so. The readme does not seem to be available in english. I notice that, for writing games with Ruby, RubyGame ( http://rubygame.seul.org/ ) makes use of ruby-opengl as well. It's docs have this to say: | Please note that Rubygame itself does not provide an interface | to OpenGL functions - only functions which allow Rubygame to | work together with OpenGL. You will need to use another library, | for example ruby-opengl, to actually create graphics with OpenGL. There's a bit more to say on Ruby + OpenGL at the wiki: http://www.rubygarden.org/ruby?OpenGL Would someone mind posting a translation of the README.EUC here? Thanks, ---John
