From: Dave Thomas Date: 2002-02-20T14:44:26+09:00 Subject: Linking opengl under windows Continuing my masochistic quest to build Ruby under mswin32, I'm trying to compile the opengl extension. I installed a 3.7 version of glut, copying the .lib files into vc98\lib. I patched extconf.rb using the patch from sfns.u-shizuoka-ken.ac.jp/geneng/horie_hp/ruby/opengl.mswin32.diff, then ran it. When I then run nmake, I get three undefined symbols when creating glut.lib: __imp____glutInitWithExit __imp____glutCreateWindowWithExit __imp____glutCreateMenuWithExit So, Windows fans, what am I forgetting to do? Cheers Dave
