I want to use rubyinline to write a simple code with inline c functions.

Here is my code:

require ‘rubygems’  
require ‘inline’

class TestC  
inline do |builder|  
builder.c "  
static void hello(int n) {  
printf(“Hello %d\n”, n);  
}  
"  
end  
end

k = TestC.new  
k.hello(5)

when I run this code, I get error as:

./inline.rb:5: undefined method `inline' for TestC:Class (NoMethodError) from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in`ge  
m\_original\_require’  
from  
c:/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in `re  
quire’  
from inline.rb:2

Would anybody help to find what’s the err?

I use ‘gem install rubyinline’ to install rubyinline and get results as  
‘Successfully installed RubyInline-3.6.2’, so I think the rubyinline  
should be installed without err.

You didn’t call your own source file ‘inline.rb’ by any chance? That  
would  
cause this error. Use a different filename.

Don’t call your file inline.rb if you’re going to require ‘inline’.
