OpenCL error message with GTX560 unter linux #13

Closed monarc99 closed 9 years ago

monarc99 commented 9 years ago

from forum: It is not really necessary that the device is OpenCL 1.2, just the platform is required. NVIDIA simply has no suitable drivers for GT/GTX 500 series.

I have a GT560Ti with driver 355.11 under linux. So this error message means, the driver is too old?

Error in OpenCL compiler

So i hope they update the opencl part too and i want to be sure, what this error message means.

OpenCL 1.2 introduced 'image2d_array_t'. I use it when 'd' > 0. How you see your driver does not recognize it and therefore error. It is an error due to the driver not compatible.

In version 0.7.3 there will be messages more understandable.
