Debugging with ruby-debug in Funny-Falcon's Performance Patched Ruby 1.9.3 and RVM


It's much easier to get this working now, simply install the following three gems in sequence. You don't need to be version specific (Ref).

> gem install debugger
Fetching: debugger-ruby_core_source-1.2.3.gem (100%)
Fetching: debugger-linecache-1.2.0.gem (100%)
Fetching: debugger-1.6.1.gem (100%)
Building native extensions.  This could take a while...
Successfully installed debugger-ruby_core_source-1.2.3
Successfully installed debugger-linecache-1.2.0
Successfully installed debugger-1.6.1
3 gems installed

Yesterday I found adding the following to the Gemfile

group :development, :test do
  gem 'linecache19', '0.5.13'
  gem 'ruby-debug-base19', '0.11.26'
  gem 'ruby-debug19', :require => 'ruby-debug'

...and running bundle install just would not work. The reason is ruby-debug19 is no longer maintained and there's a recommended fork called debugger that works on 1.9.2 and 1.9.3 and installs easily for rvm/rbenv rubies.

However, I wanted to get ruby-debug19 to install and followed the advice of this post on Stackoverflow and created a gist to allow installing this under my particular version of ruby-1.9.3-p327-fastGist: Install ruby-debug19 with Falcon patched ruby-1.9.3-p327-fast

### UPDATE: ruby-debug19 is no longer maintained, use https://github.com/cldwalker/debugger

# Install with:
# bash < <(curl -L https://raw.github.com/gist/5110684)
# Reference: http://blog.wyeworks.com/2011/11/1/ruby-1-9-3-and-ruby-debug

echo "Installing ruby-debug with ruby-1.9.3-p327-fast ..."

curl -OL http://rubyforge.org/frs/download.php/75414/linecache19-0.5.13.gem
curl -OL http://rubyforge.org/frs/download.php/75415/ruby-debug-base19-0.11.26.gem

gem install linecache19-0.5.13.gem ruby-debug-base19-0.11.26.gem -- --with-ruby-include=$rvm_path/src/ruby-1.9.3-p327-fast

rm linecache19-0.5.13.gem ruby-debug-base19-0.11.26.gem

echo "Done."

Simply perform

bash < <(curl -L https://raw.github.com/gist/5110684)

to install the above into $rvm_path/src/ruby-1.9.3-p327-fast. To edit the install path, I suggest you fork and make your own modified own gist.
