Greetings,

I’ve got FXRuby gem installed in NetBeans 6.5b

Code starts:

require ‘rubygems’  
require ‘fox16’ --\> this line returns error (from custom\_require.rb  
file)

…

and following: fox16.so:32:in ‘require’

E:/Programming/Apps/NetBeans 6.5 Beta/ruby2/jruby-1.1.3/lib/ruby/gems/  
1.8/gems/fxruby-1.6.16-x86-mswin32-60/ext/fox16/fox16.so:32: E:/  
Programming/Apps/NetBeans 6.5 Beta/ruby2/jruby-1.1.3/lib/ruby/gems/  
1.8/  
gems/fxruby-1.6.16-x86-mswin32-60/ext/fox16/fox16.so:1: Invalid char `  
\220’ (’?’) in expression (SyntaxError)

fox16.so is installed with fxruby gem.

How to make this “Invalid char `\220’ (’?’) in expression  
(SyntaxError)” run ?

Thanks.

FXRuby only works with the traditional C-based Ruby interpreter; it  
won’t work under JRuby.

You may want to check which ruby platform your Netbeans project is set  
to. Right click on the project name -\> Properties -\>Run. If it says  
Jruby you need to change it to Ruby for fox to work.

True. I’ve change Ruby Platform to pure ruby and it works.
