Device Selector Compilation Error

Hello,

 

Prior to the latest oneAPI update, I had been creating my device selector in the following way:

#if defined(FPGA_EMULATOR)
    sycl::ext::intel::fpga_emulator_selector device_selector;
#elif defined(CPU_HOST)
    sycl::host_selector device_selector;
#else
    sycl::ext::intel::fpga_selector device_selector;
#endif
    
sycl::queue q(device_selector, sycl::property::queue::enable_profiling{});

 Things had been working just fine up until today, 5/4. I adjusted the code following deprecation warnings and a compilation error to follow the new method:

#if FPGA_SIMULATOR
	auto selector = sycl::ext::intel::fpga_simulator_selector_v;
#elif FPGA_HARDWARE
	auto selector = sycl::ext::intel::fpga_selector_v;
#else  // #if FPGA_EMULATOR
	auto selector = sycl::ext::intel::fpga_emulator_selector_v;
#endif

sycl::queue q(selector, sycl::property::queue::enable_profiling{});

However, I am still getting errors when I try and compile my code with this new device selector method. My compilation command is as follows:

icpx -fsycl -qactypes -fintelfpga -DFPGA_EMULATOR src/test.cpp -O3 -o bin/test

I ran the setvars script before attempting compilation as well:

source /opt/intel/oneapi/setvars.sh > /dev/null 2>&1

The error that I am getting is this:

OpenCL platform ID is empty
OpenCL platform name is empty
Failed to find any of these OpenCL platforms:
  Intel(R) FPGA Emulation Platform for OpenCL(TM)
  Intel(R) FPGA Emulation Platform for OpenCL(TM) (preview)
llvm-foreach: 
icpx: error: fpga compiler command failed with exit code 14 (use -v to see invocation)

 

Any ideas on how to fix this issue would be greatly appreciated, thank you!

My apologies everyone, it seems I have the incorrect Intel forum, I meant for this to be in the Intel Devcloud forum

sycl::queue q(selector, sycl::property::queue::enable_profiling{});

 


The code above should be "#ifdef FPGA_EMULATOR" (note the bold ifdef).

Thank you for the suggestion, however, this unfortunately did not solve my issue. As reference, I'm just following the Intel documentation for the new way to use the device selector as seen through this link:

https://www.intel.com/content/www/us/en/docs/oneapi/programming-guide/2023-1/device-selectors-for-fpga.html 

I did initially miss the note to make use of "defined" with the if statements, and thus changed the code to: 

#if defined(FPGA_SIMULATOR) and #elif defined(FPGA_HARDWARE)
