Hello, I'm sorry I may misunderstood relationship between icpx and clang++, but when I use icpx with DPC++ plugin to compile cloudsc-sycl, I did met some error messages seems related to LLVM/clang:

llvm-foreach:
icpx: error: ptxas command failed with exit code 255 (use -v to see invocation)
Intel(R) oneAPI DPC++/C++ Compiler 2024.1.0 (2024.1.0.20240308)
Target: x86_64-unknown-linux-gnu
Thread model: posix

I guess it may be related to CUDA. When using CUDA nvcc, adding -rdc=true as an compiler option may solve the "Unresolved extern function 'xxxxx' " issue. As for icpx, I found the compiler option "-fgpu-rdc", but it didn't solve my problem.
