In Ruby 1.8.7 and Rails 2.3.18, I used Dl.dlopen to load intel fortran
dll
like the following
require ‘dl’
…
sspath = Pathname.new( ".../lib/libsamplesize.dylib" )
ss = DL.dlopen( sspath )
samplesize = ss[ "samplesize_", "iiddS" ]
session[:n], args = samplesize[ session[:nmax], session[:delta],
session[:conf], session[:errmsg] ]
but I got error message at line
require ‘dl’
This error occurred while loading the following files:
dl
Thanks!

I am using Ruby 2.1.0 and Rails 4.1.2 now, and ‘dl’ no longer works?

That’s a very short error message. What did the rest of the error say?

DL was deprecated in Ruby 2.0 and removed in 2.1 in favor of Fiddle.

Thanks! I will check fiddle out and post if I have any questions. It can
call .dylib?

I don’t see anything else though, let me copy the whole page:

Dear Matt:
I have tried fiddle, but couldn’t make it to import functions in .dylib
(Fortran dll generated by intel
fortran compiler) that I could use DL to import successfully before.
Any
suggestions?
Thanks!
Liz
Does fiddle work in Mac? I saw some comment that it doesn’t work in all
platforms.
