LLVM Error while implementing clBuildProgram

Hi all,

Recently I bought a new laptop.

I get the following error after starting clBuildProgram when running any of OpenCL code.

LLVM ERROR: Unknown error while opening the igdclbif.bin

clGetPlatformIDs, clGetDeviceIDs, clCreateContext, clCreateProgramWithSource all works.

I assume the complicated kernel code is cause and change it to the following simply

void a() {

}

But the problem is not disappeared.

I think the driver has problem.

When I triy to update graphics driver, I can see the message that the most recent driver available is already installed.

Does anyone have any idea to solve it?

Thanks all.
