Forum: Ruby-Gnome 2 rb_thread_critical - anyone knows this error?

I try to run menu.rb from gtk2/ sample directory:

rb menu.rb

Error is this:


/pkg/Ruby/1.9.3p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in

(My ruby prefix is /pkg/Ruby/1.9.3 etc..)


My glib.so probably does not have glib2.so rb_thread_critical symbol.

Does one of you know how to get this symbol? Or is there a workaround?
So far, everything else seems to work ok when I compile the rubygnome
bindings.

It seems that your build has a problem.
Could you show how to install Ruby/GLib2?

rb_thread_critical is defined in Ruby 1.8 but it's not
defined in Ruby 1.9. So it's strange that your Ruby/GLib2
on Ruby 1.9 refers the symbol.
