Generate texture

ruby-talk

I am trying to generate a texture.

When I execute: @texture = glGenTextures(1).first

I get the following error:

[BUG] Bus Error
ruby 1.8.4 (2005-12-24) [i686-darwin8.8.1]

Any help would be great. Thanks.

Below is a more complete snippet of the code that I am using:

#!/usr/local/bin/ruby

require 'rubygems'
require 'opengl'

include Gl
include Glu
include Glut

class GlutTest

  def initialize
    puts "=== GlutTest.initialize ==="

    @texture = glGenTextures(1).first

    # Setup the GLUT display loop callback
    @display = lambda do
      glClear(Gl::GL_COLOR_BUFFER_BIT | Gl::GL_DEPTH_BUFFER_BIT)

      gluOrtho2D(0.0, 128.0, 0.0, 128.0)

      glutSwapBuffers
    end

...

end

The issue was that the call to generate a texture must be inside of a
glut call back.
