Fresh install problem


So my old computer fried a motherboard.
So after bying, building and installing my new computer.
I return to wxruby and install it via ‘gem install wxruby’
and run my old programs. BUT they don’t work.

They return this error.

version `GLIBCXX_3.4.9’ not found (required
by /usr/lib/ruby/gems/1.8/gems/wxruby-1.9.8-x86-linux/lib/

  • /usr/lib/ruby/gems/1.8/gems/wxruby-1.9.8-x86-linux/lib/
    from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
    require' from /usr/lib/ruby/gems/1.8/gems/wxruby-1.9.8-x86-linux/lib/wx.rb:12 from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:32:ingem_original_require’
    from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:32:in
    `require’ from dnet.rb:1

Is this something I can fix ?


This error means that glibc is of a different version then the one that
compiled with wxRuby gem. It could be new or it could be older. It all

The only way I can think to fix this, is to go through the self-compile

See here to self-compile wxRuby:

If you have any questions about self-compiling, feel free to ask, and I
someone else will be happy to help.
