All: Pardon this noobish question. I'm trying to bring up ruby-opengl
on my Mac OS X (v 10.4.10).
I ran "sudo gem install ruby-opengl" without any trouble -- gem
announced that it was loading ruby-opengl 0.40.1 as well as mkrf-0.2.2
-- so far so good! I poked around and found that it had installed the
following file (among others):
LoadError: no such file to load -- opengl
from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require'
from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`require'
from (irb):106
from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:399
My question: My guess is this is a problem with paths. What is the
cleanest remedy? Do I extend my path, make symbolic links, or move the
opengl files?

I think you want to require 'gl' rather than 'opengl'. With a working
install of ruby-opengl on 10.4.10 I have the following in a working Ruby
script:

But when I do irb(main):003:0> require 'gl'
I get the following error:
LoadError: Failed to lookup Init function ./gl.bundle
from ./gl.bundle
from (irb):2
(Well, 'opengl.rb' file contains line "require 'gl'" anyway, but when I
do
irb(main):003:0> require 'opengl', I receive:
LoadError: Failed to lookup Init function ./gl.bundle
from ./gl.bundle
from ./opengl.rb:16
from (irb):1:in `require'
from (irb):1 )
I also tried to test run 'plane.rb' file located in
/usr/local/lib/ruby/gems/1.8/gems/ruby-opengl-0.40.1/lib/examples
using TextMate and got the following:
/Volumes/TextMate1.5.5/TextMate.app/Contents/SharedSupport/Support/lib/
scriptmate.rb:107:in `initialize': Permission denied -
/usr/local/lib/ruby/gems/1.8/gems/ruby-opengl-0.40.1/examples/plane.rb

(Errno::EACCES) from /Volumes/TextMate
What am I doing wrong?
I think TextMate needs write access to files to run them (bug?). I had
the very same problem yesterday, even with a 'properly' installed
TextMate, and I ended up copying the example .rb files to the Desktop.
Could run them from there without problems.

Ok, I copied an exmple rb file to the Desktop where TextMate is, but
still get:
LoadError: Failed to lookup Init function
/usr/local/lib/ruby/gems/1.8/gems/ruby-opengl-0.40.1/lib/gl.bundle

Don't know if it might be the same problem, but just in case. I was
trying to install opengl in Ubuntu, but couldn't make it work, until
someone pointed to me that opengl.0.40.1 required version 1.9+ of
rubygems. So maybe you could try to upgrade to version 1.9 to see if
that's the problem?
In Ubuntu:
sudo gem update --system
Don't know how to do it in Mac OS X, though.
Hope this helps,
Jesus.
