Hi,

I am getting an error:

ruby: symbol lookup error:  
/Programs/Ruby/1.8.7p160/lib/ruby/site\_ruby/1.8/i686-linux/gtk2.so:  
undefined symbol: gtk\_file\_system\_error\_quark

My relevant versions (all compiled from source) are:

gtk: 2.14.7  
glib: 2.20.3  
gcc: 4.3.3  
atk: 1.22.0  
ruby: 1.8.7

Perhaps one of you guys has an idea what the error could be. This haunts  
me since some time and I can not use ruby-gtk until I managed to solve  
it.  
Perhaps some version is incompatible or something.

I googled a bit and found some references like on  
[http://bugs.archlinux.org/task/11623](http://bugs.archlinux.org/task/11623) but I am not smart enough to  
understand it entirely.

I wouldn’t mind to patch this away (i dont think I need it in my code),  
but I would really like to continue working with ruby-gtk as soon as  
possible again. Did make a break of a few weeks already… 🙂

Could you re-run ‘make clean && ruby extconf.rb && make’?

‘ruby extconf.rb’ for Ruby/GTK+ detects whether your GTK+  
has gtk\_file\_system\_error\_quark() or not.

## Thanks,

Thanks - it works now.

I cleaned up my gtk install as well. (I was using a higher gtk version  
before that, now I downgraded cleanly, and ruby-gtk works happily.)
