Question

I need to use ruby 1.8.6 to run a legacy script. I’ve installed NetBeans 6.9.1 and I’m trying to use the fast debugger but when I try to install it I get:

/home/eianni/.rvm/gems/ruby-1.8.6-p420@xml2rpc/gems/rubygems-bundler-0.3.0/lib/rubygems_bundler/regenerate_binstubs_command.rb:34: warning: parenthesize argument(s) for future version
Building native extensions.  This could take a while...
ERROR:  Error installing ruby-debug-ide:
    ERROR: Failed to build gem native extension.

Gem files will remain installed in /home/eianni/.rvm/rubies/ruby-1.8.6-p420/lib/ruby/gems/1.8/gems/ruby-debug-ide-0.4.9 for inspection.
Results logged to /home/eianni/.rvm/rubies/ruby-1.8.6-p420/lib/ruby/gems/1.8/gems/ruby-debug-ide-0.4.9/ext/gem_make.out

This is probably because the ruby version is too old, but is there a way to tell Netbeans to use a different version for ruby-debug-ide. I can install withouth problems ruby-debug-ide 0.10.0.

I’m using Ubuntu 10.04

In order to use ruby-debug-ide 0.4.9 with Ruby 1.8.6, you have to install ruby-debug-base 0.10.3 and linecache 0.45.

To know and manage your gems in Netbeans :
