undefined symbol: _ZN4sycl3_V15queueC2ERKNS0_6deviceERKSt8functionIFvNS0_14exc

[Hongbo_R_Intel]

Hello, I have a piece of OneAPI code like this:

#include <sycl/sycl.hpp>
#include <sycl/ext/intel/fpga_extensions.hpp>

#include "exception_handler.hpp"

....

sycl::queue q_device(sycl::ext::intel::fpga_selector_v, fpga_tools::exception_handler, sycl::property::queue::enable_profiling());

...

It is compiled on a S10 machine s001-n142 in commands like:

source /glob/development-tools/versions/oneapi/2023.2/oneapi/setvars.sh --force

icpx -fsycl -fintelfpga demo.cpp some_fpga_image.a -o demo.out

The commands finished successfully, but when running there is an error:

./demo.out

symbol lookup error: undefined symbol: _ZN4sycl3_V15queueC2ERKNS0_6deviceERKSt8functionIFvNS0_14exception_listEEERKNS0_13property_listENS1_13DiscriminatorE

I looked at the demo.out with "nm -D demo.out" and indeed the symbol is undefined. I guess there might be some libraries I missed in the "icpx" command above?

Thanks!

I am not sure if the error is related with my devcloud batch submission. But in an interactive command window, I removed the generated .out file and other related files, then rebuilt the .out file in the same commands, and the newly generated .out file runs just fine. Not sure why, but this issue is solved.
