Hello!

I have a pb with ruby rails and swig

I have wrapped a c library I have made into ruby using swig  
now I want to use it in a rails project

I have already tested my library with a ruby script and it worked well

I added the path to the swig generated library in my script and it  
recognized my library

but when I tired to call my library in my rails project, it did not  
recognize any of the generated files even when I added their path (using  
"$:  
\<\< “path/to/swig/library”)

have anyone an Idea on how to do that

I know that I have to post this message in the rails mailing list, but  
nobody has replied yet, so I try here

thank you
