Hello everybody
I have an NVIDIA 6200 card under OpenSuSE 11.1, drivers and all installed glxgears giving 2000-3000 fps on an old Athlon 64. I installed ruby gems and used (as root) the command
# gem install ruby-opengl
to get and install openGL bindings for ruby. The command completes with no complaints, everything goes smoothly. Then under a normal user I am trying to run some of the Redbook examples, found under
> /usr/lib64/ruby/gems/1.8/gems/ruby-opengl-0.60.1/examples
without success. They fail with the error that the requested openGL isual is not available.
Any idea how to get this one flying?
Regards,
George
To be more precise:
# cd /usr/lib64/ruby/gems/1.8/gems/ruby-opengl-0.60.1/examples/RedBook
# ruby aapoly.rb
yields:
aapoly.rb:42:in `require': no such file to load -- opengl (LoadError)
modifying the code as follows:
# diff aapoly.rb aapoly_mod.rb
41a42,43
> require 'rubygems'
> gem 'ruby-opengl'
yields
ruby aapoly_mod.rb
freeglut (aapoly_mod.rb): ERROR: Internal error <FBConfig with necessary capabilities not found> in function fgOpenWindow

Major opcode of failed request: 4 (X_DestroyWindow)
Resource id in failed request: 0x0
Serial number of failed request: 25

What is going wrong?
