From: "AMILIN Aurélien" Date: 2010-04-05T20:06:20+09:00 Subject: Re: /usr/bin/ld: cannot find -lruby The problem is that ruby-opengl need to compile some C code to make the bindings between ruby and opengl. And for that you need ruby source code. The easy way is to install with your package manager (apt-get, yum ...) the source code of ruby the package name should be ruby-dev, ruby-devel ... something like that (depending on your linux distribution) The hard way is to put the source code you've download into the right directory but I don't know how Then you should be able to install ruby-opengl Le 05/04/2010 12:46, Venkat Akkineni a écrit : > Hello > > I got the following error when I tried to install ruby-opengl > gem.
