Installing ruby-opengl on Windows and Ruby 1.9.

[LB]

First: Follow this tutorial: https://groups.google.com/d/msg/rubyinstaller/vMR5mQVA_88/aZqLyjyQiSYJ (by Tomasz Błajek).

You will get an error with last step (building the gem). At this point you should have this directory tree:

Code: [Select]

(folder) doc
(folder) examples
(folder) ext
(folder) lib
(folder) test
 (file)  metadata
 (file)  Rakefile

Open "metadata" and add after line 13:

Code: [Select]

licenses: []

Then run:

Code: [Select]

gem build metadata

After you will have to download and install Glut to the devkit. Download it here: http://user.xmission.com/~nate/glut.html (the bin option).

Unpack and move 'glut.h' to "<devkit path>\mingw\include\GL", 'glut32.lib' to "<devkit path>\mingw\lib" and 'glut32.dll' to "C:\Windows\System32".

Now run:

Code: [Select]

gem install ruby-opengl-0.60.1.gem

You shouldn't get any errors.

(I'm now testing it with rbSFML.)
