Cannot find Xeon with OpenCL drivers with SYCL support

Hi,

I'm trying to run a sycl app using DPC++ Spir-v backend but I'm facing a lot of issues with installing the right opencl driver.

Configuration

Description

I tried to download the OpenCL CPU Runtimes for Linux from there: OpenCL™ Runtimes for Intel® Processors
After the installation, clinfo returns the correct device but I can't compile even a simple sycl app using the CPU backend (-fsycl-targets=spir64_x86_64)

Looking at the opencl runtime page, I saw that there is a dedicated section for opencl runtimes with SYCL capabilities, so I tried to download the intel-oneapi-opencl-runtimes from the apt repository.
However, no OpenCL devices are found with clinfo with this method.

Am I missing something?

Additional info for OpenCL Runtimes 18.01

Hi,


> However, no OpenCL devices are found with clinfo with this method.

Did you set oneapi environment before clinfo command?

For example, setting oneapi environment via command "source /opt/intel/oneapi/setvars.sh", then use "clinfo -l" command, all the devices are displayed.


Thanks
