Hi

I’m using rake+setup.rb to create a gem. It has a data-dir which is  
supposed to go into the shared data directory. My issue now is: how do I  
know in the executable where that data-dir went?  
Similar thing for the conf directory.

Regards  
Stefan

Thanks to cout in [irc.freenode.org/#ruby-lang](http://irc.freenode.org/#ruby-lang) I solved my problem. In  
case somebody googles this thread due to the same problem, here’s the  
solution:  
require ‘rbconfig’  
data\_dir = Config::CONFIG[‘datadir’]

If you want put architecture dependent files, they shouldn’t go  
the shared data directory, use ‘libexecdir’ instead.
