OpenCL error -30 (CL_INVALID_VALUE), What's Wrong? about dynamic_ocl

[dmarcuse]

This is intended behavior. It looks like your Nvidia OpenCL driver only supports OpenCL 1.2, and the device itself only OpenCL 1.1. Meanwhile, many of the information types this library supports were added in OpenCL 2.0 or later, so they'll just return an error on your system instead. If you don't need them, you can simply ignore them.

Actually, I missed the second half of your logs, where the example crashes. It looks like there might actually be a bug in my code here because it crashes when no devices are available from the Mesa OpenCL driver - I'll look into it.

I've pushed a commit that should fix this - could you try it out and see if it fixes it? If so, I'll publish a new alpha release of the crate.
