I have a Rails app that has been running fine for months. The other day I went through the laundry list of upgrades in Ubuntu and installed them all. Suddenly, I can't start my dev server because of failures in linecache. I've read various threads on this topic:
ruby_threadptr_data_type error
Rails with ruby-debugger throw 'Symbol not found: _ruby_current_thread (LoadError)'
http://isitruby19.com/linecache
http://antisnatchor.com/debugging_ruby_1.9.3p125
Installing linecache19 for Ruby 1.9.2 via rvm
Still, after spending hours on waiting for installs to fail, I can't get my rails dev server to start.
My versions look like this:
~/app> which ruby
/usr/share/ruby-rvm/rubies/ruby-1.9.3-p125/bin/ruby
~/app> which rvm
/usr/share/ruby-rvm/bin/rvm
~/app> rvm current
ruby-1.9.3-p125
~/app> ruby -v
ruby 1.9.3p125 (2012-02-16 revision 34643) [i686-linux]
~/app>
And here's what happens when I try to install the current version of ruby-debug:
~/app> gem install 'ruby-debug-base19x'
Fetching: ruby-debug-base19x-0.11.29.gem (100%)
Building native extensions. This could take a while...
ERROR: Error installing ruby-debug-base19x:

And my gemfile (the relevant bit anyway):
group :development, :test do
...
gem 'linecache19', :git => 'git://github.com/mark-moseley/linecache'
gem 'ruby-debug-base19x'
gem 'ruby-debug19'
end
Anyone have an idea of what's actually going on here? I'm pretty stumped. I'm willing to start over from scratch if I need to. I just need to know the best way to go back to bare canvas and what to paint.
