ruby_threadptr_data_type error

Question

I'm starting up a new rails app with the latest version of rails (3.1.3). Rails crashes when I try to start up the server. First I fixed this bug, and now I'm getting this one

ruby-debug-base19-0.11.25/lib/ruby_debug.so: undefined symbol: ruby_threadptr_data_type 

There's a discussion about this going on here, but I can't make enough sense of it to get things to work.

UPDATE

I updated the version of ruby-debug

gem 'ruby-debug-base19x', '~> 0.11.30.pre4'

and have now moved on to this error

linecache19-0.5.12/lib/trace_nums19.so: undefined symbol: ruby_current_thread

Answer 1

Ok, it turns out that both ruby-debug and linecache needed to be manually updated to the latest versions. These lines in my gemfile did the trick

gem 'linecache19', :git => 'git://github.com/mark-moseley/linecache'
gem 'ruby-debug-base19x', '~> 0.11.30.pre4'
gem 'ruby-debug19'

To run specs, you need to run bundle exec rspec -d spec

this is the same answer as the one by @Jakob_Cosoroaba – Forjudge

@Forjudge - yeah, it is. This one was here for about a week before he gave his answer. Not sure why he duplicated it. – Garamond

Doesn't work. Still have the same problem. Tried with required, and without git and version definition. The same. – Elastic

This worked great for me on Ruby 1.9.3-p0 and Rails 3.2.0.rc2. Thanx! – Takamatsu

Verified to be working with 1.9.3-p125 and OSX Lion. Why this is so hard to keep in line I have no idea. shakes fist – Fickle

@Fickle - yeah, when I posted this I never thought it would still be the right solution 5 months later. – Garamond

Answer 2

At last I found the problem. The debugger in RubyMine starts without bundle exec, so it doesn't use linecache19 from git. You need to install it manually.

Resolution of the problem found here: http://youtrack.jetbrains.com/issue/RUBY-9418?projectKey=RUBY

gem uninstall linecache19
gem uninstall ruby-debug-base19x
curl -OL http://rubyforge.org/frs/download.php/75414/linecache19-0.5.13.gem
gem install linecache19-0.5.13.gem
gem install ruby-debug-base19x –-pre

Make sure to uninstall all linecache19 and ruby-debug-base19x!

Answer 3

The following lines worked for me:

gem 'linecache19'
gem 'ruby-debug-base19x'
gem 'ruby-debug19', :require => 'ruby-debug'

(Hat tip to declan. His comment didn't work for me, but it gave me the idea to add linecache19.)

I tried everything else as well and this was the only solution that solved my issue. For those updating to Ubuntu 12.04, ruby will be auto updated to 1.9.3p0. – Scholl

Answer 4

after trying all advise on stackoverflow, the following combination worked for me

gem 'linecache19', :git => 'git://github.com/mark-moseley/linecache'
gem 'ruby-debug-base19x', '~> 0.11.30.pre4'
gem 'ruby-debug19'

I'm running Rails 3.1.3 on Ruby 1.9.3-p0 with RVM

when I set :require => 'ruby-debug' the server would not start.

Answer 5

It's repost from this

I also ran into this, and found the solution in Ruby 1.9.3 and ruby-debug. You need to install not-yet-officially-released versions of ruby-debug-base19 and linecache19. The currently released versions indeed cause the exception you had.

Use this gist.

#To install ruby-debug on Ubuntu ruby-1.9.3 you need to download from http://rubyforge.org/frs/?group_id=8883

linecache19-0.5.13.gem 
ruby_core_source-0.1.5.gem 
ruby-debug19-0.11.6.gem 
ruby-debug-base19-0.11.26.gem

#Then in your console

export RVM_SRC=/your/path/to/ruby-1.9.3
# Note, your source path should be something like /home/user/.rvm/src/ruby-1.9.3-p0

gem install archive-tar-minitar
gem install ruby_core_source-0.1.5.gem -- --with-ruby-include=/$RVM_SRC
gem install linecache19-0.5.13.gem -- --with-ruby-include=/$RVM_SRC
gem install ruby-debug-base19-0.11.26.gem -- --with-ruby-include=/$RVM_SRC
gem install ruby-debug19-0.11.6.gem -- --with-ruby-include=/$RVM_SRC

I tried it and it's work!

This is solve of our problems.
