OpenCL Build Program Error with 1.2 platform

Philip_C_3 — Mon, 23 May 2016 04:57:24 GMT

Hello, I am in need of some assistance...

I've downloaded and installed Intel OpenCL Applications SDK 2016 and am trying to run my OpenCL projects on Windows 10. When I select the Experimental OpenCL 2.0 CPU Platform everything goes smoothly and the program exist normally. If I select GPU HD Graphics 4000 (OpenCL 1.2) I get a run time error during Program build saying that the compiler cannot find a header file included in my kernels.

Setup: Windows 10 with current HD Graphics 4000 driver (15.33.xx) and Intel Core i7-3630.

I am using cl.hpp with CL_USE_DEPRECATED_OPENCL_1_2_APIS if that helps.

Could this be the way a OpenCL compiler is handling platform versions 1.2 differently than platforms with version 2.0? Let me know if additional information can help.

Thanks!

Hi Philip,

The CPU and GPU compilers for OpenCL are quite different. Could you please provide your kernels? Are you specifying -I option to the clBuildProgram function so that compiler can find your header files included in the kernel. A small reproducer of this issue will go a long way :) If you don't want to share your code in a public forum, you could send me a private message with the attachment (our forum supports that capability).

Hi,

Even I am facing a similar issue here, wherein the code compiles successfully for CPU but fails for Intel HD 2500 Graphics. Please, may I know the solution to fix this problem?
