To install gems that depends on binary extension, like yours, you need a compiler. Ruby needs a version specific compiler, the same used to build Ruby, which is Visual C 6.0 Unless you have a license, that compiler is not available. I suggest you play with or try out the preview version of the new One- Click Installer based on GCC, let you build gems with native extensions without these issues.

I fixed my issue. I went directly to: [http://rubyforge.org/frs/?group\_id=2103](http://rubyforge.org/frs/?group_id=2103) … and downloaded the ruby-opengl-0.60.1-x86-mswin32.gem … ran gem install ruby-opengl-0.60.1-x86-mswin32.gem … … And it installed correctly with no issues. I looked through your links though and the second one was very well written - I especially enjoyed your ideas about user file separation on a different partition. Good read! ---

Hi Luis, Wish I would have known this before I did all the things I just finished doing. I figured out that I was missing cl.exe and so I grabbed the latest visual studio 2008 express and installed it and then encountered problems with path variables. So, I updated all of the path variables and went to run the gem install and encountered the … MSC Version Mismatch error… At which point I looked through the doc notes for opengl and saw that the compiler has to be MSC 6.0 (which I believe the latest version I have is not compatible). So, before I go heads into another session of fix this/fix that… let me make sure I understand what it is you are saying… The version I need is no longer available unless I have a license so I need to play with the one-click-installer that’s based on GCC? No other way around it eh? ---

Well, you can get VC8/9 to build extension for VC6 version of RUby, but is not the best approach I’ll suggest (if you appreciate your mental health). GCC based Ruby is the candidate for One-Click Installer, since building extensions with 12 years old compiler is kind of obsolete (that is VC6).
