glTail Boot Errors

Question

For all those who don't know what I am talking about, it's glTail from Fudgie.

On my Mac at home, I have never been able to get glTail to work. I have gotten it to work on my work Mac. This is just a last resort, as the past 2 days have been nothing but seems like wasted time.

I have the same libraries installed: Ruby 1.8.6, Gem 1.3.1, net-ssh 1.1.4, Chipmunk 2D, ruby-opengl 0.60.0 and file-tail 1.0.3.

Here is the command that I run to try to start it up:

./gl_tail configfile config.yaml

It says right off the bat (almost instantaneously):

-macbook:bin Garrett$ ./gl_tail configfile config.yaml
./../lib/gl_tail/engine.rb:300: [BUG] Bus Error
ruby 1.8.6 (2008-03-03) [universal-darwin9.0]

Abort trap

If you look at engine.rb, it's the first line:

    def start
      glutInit() # Line 300
      glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE)

      glutInitWindowPosition(0, 0)
      glutInitWindowSize(@config.screen.window_width, @config.screen.window_height)
      glutCreateWindow('glTail')

I have a feeling it's something along the lines of GLUT not being installed properly. I am not expecting too much help, as the code it self has very little documentation as it is. But seeing as it's being killed right away I have a feel maybe it's something that isn't updated all the way, most likely OpenGL.

I'm not sure if this is at all helpful to you coming from a linux user, but here goes... I think you are missing the libglut-headers, indeed. If you are installing through gems, that's the only external thing you would need. On linux, I only have to install the libglut3-dev package, then gem install gltail it can build ruby-opengl with that.

So, try to find the libglut development headers on your platform. Hope that helps!
