Debugging with JRuby 1.4.0RC1?

[homerlex-3]

Using Netbeans 6.7.1 on Vista.  Debugging works fine with JRuby 1.2.



I installed JRuby 1.4.0RC1.  The app runs just fine but if I try to debug it fails trying to install the fast debugger.  Error is shown below.



Has anyone gotten this working?



ERROR Message:



JRuby limited openssl loaded. gem install jruby-openssl for full support.

This blog might help: http://blogs.sun.com/divas/entry/installing_your_own_jruby_to

especially this part:
You will need the debugger gems. Follow the instructions on the NetBeans Ruby Debugger wiki page. Make sure you get the correct versions -- the ones noted on the wiki page. If you opted for a separate gems repository in the previous step, then add --install-dir your-repo-path to the gem install commands.

The above assumes that JRuby 1.4 is in your path

A note about the "native extensions" error messages. You will see these whenever you try to use native gems with JRuby. I explain this here: http://blogs.sun.com/divas/entry/using_gems_with_jruby.

Installing ruby-debug-ide 0.4.9 fails due to a bug in JRuby (I believe),
check this message for a workaround:

http://www.nabble.com/Re%3A-Trying-to-install-ruby-debug-ide-on-jruby-1.2.0-p25525773.html

I guess on your JRuby 1.2.0 you have ruby-debug-ide 0.4.6 which doesn't
suffer from this issue.

HTH,
Erno
