symbol lookup error:undefined symbol: rb_str_new_static

[Gregor Mitzka]

Hey everybody,

I am new with Passenger and I try to get things started. But I have an problem I cannot solve at my own and there doesn't seem to be much information about this. When I try to start my rails app I get an error like this:

[ 2015-04-17 13:03:08.0517 15740/7f84ec1a3700 App/Implementation.cpp:287 ]: Could not spawn process for application [edited]: An error occurred while starting up the preloader. It exited before signalling successful startup back to Phusion Passenger.
  Error ID: ae45bc90
  Error details saved to: /tmp/passenger-error-FAz9bs.html
  Message from application: An error occurred while starting up the preloader. It exited before signalling successful startup back to Phusion Passenger. Please read <a href="https://github.com/phusion/passenger/wiki/Debugging-application-startup-problems">this article</a> for more information about this problem.<br>
<h2>Raw process output:</h2>
<pre>
/usr/bin/ruby: symbol lookup error: /usr/local/lib/ruby/gems/2.2.0/gems/json-1.8.2/lib/json/ext/parser.so: undefined symbol: rb_str_new_static
</pre>

Is there anybody who has an idea about what would solve the problem? I also posted an issue request at the ruby bugtracker but to me it seems like an issue of Passenger.

Thanks for help and any advice.

Regards,
Gregor

PS: I'm running on Ubuntu 14.4 LTS, Passenger 5.0.6 and Ruby 2.2.2.

Hi,

This is likely not a problem in Passenger. rb_str_new_static I think is a very new feature of Ruby, one of your gems has a problem with it. If you look in the error file Passenger generated for you (in /tmp/passenger-error-FAz9bs.html) there should be a longer stack trace that could give a hint to what gem is having the problem.

Kind regards,

Tinco
