(Gem::Installer::ExtensionBuildError) ------=_Part_126925_23744086.1177345312900 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Content-Disposition: inline Hi. I have questions. Because I need to generate complex simple 3D pictures in Windows XP, I want to use OpenGL, especially in Ruby. Please consider that I'm a complete newbie in OpenGL. Problem is... I cannot 'gem' ruby-opengl. Here are two qustions. 1. What do I need to install before installing ruby-opengl? What I did: (1) get opengl.dll, glu.dll, glut.dll from the internet and copied them to the windows sytem32 folder. (2) Installed ruby 1.8.6, rake, mkrf as shown in " http://ruby-opengl.rubyforge.org/build_install.html" 2. But I cannot install ruby-opengl. Error messages are like this. (gem version is 0.9.2) What I did: (1) try installing ruby-opengl directly using gem (2) raking in ruby-opengl folder. In (1), I get, "ERROR: Failed to build gem native extension. In (2), I get, undefined method 'exitstatus' for nil:NilClass Following is the detail of the output Thank you.
