require 'barracuda'
irb: symbol lookup error: /var/lib/gems/1.9.1/gems/barracuda-1.3/ext/barracuda.so: undefined symbol: clGetDeviceIDs
(then dumps me out to shell)

Also: on my system OpenCL/OpenCL.h is /usr/include/CL/opencl.h

I am a Ruby beginner and I am trying to get this to work on Ubuntu. I downloaded the Intel OpenCL SDK, which put a bunch of files in /usr/lib64.

When I run rake, here is what I get:
rake/gempackagetask is deprecated. Use rubygems/package_task instead
cd ext && ruby extconf.rb
checking for CL/cl.h... yes
checking for main() in -lOpenCL... yes

libOpenCL.so exists in /usr/lib64/libOpenCL.so. How do I get the tests to run and see that file?

Here's one of them, 'to_float.rb',

I was hoping to try out Barracuda, and was neither able to run it from the gem, or when building it from the source off of GitHub. Here's the test output (it's complaining about rb_ary_replace).

The v1.3 gem will install but NOT run with 1.9.2 on OS X Snow Leopard, however, when I clone the source, `cd ext; make distclean; ruby extconf; make', all is well. Not sure why exactly, but maybe it's because the binaries are actually committed to the repo? It's that's the case, this is failing for everyone on Ruby 1.9

The error is thus:

rake install
sudo gem install pkg/barracuda-1.3.gem --local
