PI_ERROR_DEVICE_NOT_AVAILABLE while executing/debugging FPGA_Compile example on EMULATOR

    Hello, I was able to solve the problem,

    Turns out setting the variable CL_CONTEXT_MPSIM_DEVICE_INTELFPGA causes problems with emulation and debugging. Unsetting this variable fixed my problem.

Hello, thank you for your response. I been using GCC version 13.2.0, Quartus Prime and OneAPI version 24.2 with FPGA support package installed on Ubuntu 24.04.1 LTS when I was doing the steps I mentioned in my post. I didn't make any changes to the files on Github repository. Unfortunately my problem persists.

    I just ran the OneAPI diagnostic tool and I get the following error

    Check name: dpcpp_compiler_sys_check
Description: This check verifies if the environment is ready to use the Intel(R) oneAPI DPC++ Compiler.
Result status: FAIL
Intel(R) oneAPI DPC++ Compiler requires gcc version 5.1 or higher.
Warning: INTEL_FPGA_ROOT is not set. Warning: Open Programmable Acceleration Engine (OPAE) driver was not found.

    However, my pc is using gcc version 13.2.0 and I couldn't find any information on forum or the oneAPI documentation regarding how to set INTEL_FPGA_ROOT. In addition to that there are bunch of "gcc4.8" directories inside oneAPI installation directory that is installed with basekit.
