If you have a fix and submit it via pull request I can approve it rather
quickly and get this fixed for you. Otherwise ill have to take a look when
I get a chance and hopefully implement a fix for you. Thanks for reporting.

Dears,
I'm evaluating aparapi for one of our project, and a requirement for it is
that it runs pure java even if no opencl device is available.
I've designed a simple test case using the guide but the test fails:

this exception is thrown when the program its the line:
List<OpenCLPlatform> platforms = (new OpenCLPlatform()).
getOpenCLPlatforms();
Going through the code, it seems that he try to check if opencl is
available on the machine running OpenCLLoader.isOpenCLAvailable(), inside
the init static block of that class it try to load the native library, and
it fails as it's not available. Anyway that exception is not catch and
everything breaks.
It catches IOException but that does not catch the UnsatisfiedLinkError.
Thank you and regards,
Fernando

there are a few opencl implementations available for linux. i know at least one of them has CPU support. you may only need to install that in the system. https://packages.ubuntu.com/search?keywords=opencl&searchon=names&suite=yakkety§ion=all |

@automenta it's not about opencl support, but opencl device detection by aparapi |
