I have a C program that uses a .dylib, this library is 32bit, to get it working I had to compile it with gcc using the -m32 option.

I am now trying to integrate the C code with Ruby but when I try to run it from console I get ***Unable to open library: dlopen(library.dylib, 2): no suitable image found. Did find: library.dylib: no matching architecture in universal wrapper*** which is the same I get if I compile without the -m32 using gcc.

Do you have any ideas? — I don’t have the source of the .dylib..
THANK YOU!!

(Couple of typos: “string = STree::Sting.new ‘foo’”, “get the tring length as an integer”

@walmeister, FFI is slower and most FFI ports to JRuby got rewritten in pure java (like nokogiri for instance). Ruby C extension API is well known and supported by CRuby, MacRuby and Rubinius

I’m just wondering why more people don’t use FFI, which looks to me like it has a number of advantages like, working with JRuby, Ruby 1.8.x and Ruby 1.9.x, etc. and no recompilation step.
