Hi @tarelli ,

Which version of JavaCL are you using?
This looks like #387, which is fixed in the latest snapshot (I'm long overdue to perform a new release :-S).

Cheers

Hi @ochafik,
I did try also with SNAPSHOT-1.0.0 back to when you fixed that with no luck, same error. When do you think you are going to be able to release again (would be handy so that I can point to the new version anyway)?
Thanks

Hi @tarelli ,

Could you please try again with the latest 1.0-SNAPSHOT? There's a magic one-line fix that might help...
Release is at hand if this is fixed :-)

Cheers

On an AMD ubuntu machine I was able to resolve the issue by using the AMD-APP-SDK-v2.8.1.0 SDK.
