I have a linux box with oneAPI 2023.0 and the latest CUDA plugin from Codeplay. I have a problem compiling the examples/cuda_interop project from this repo: https://github.com/codeplaysoftware/SYCL-For-CUDA-Examples. The simpler project example/vector_addition compiles and runs well.
Hi Rafa,
Is it possible to confirm if it is just this example that fails to build besides the vector_addition example?
I have passed this issue onto second support who are closer to the development of the examples.
Thanks
Illya
It seems there is a bug with this example. The file is not included with the oneAPI toolkit. It looks like it should be.
ATM is is shipped with dpct, not the compiler. We have noted the issue to be resolved for the next oneAPI release.
Sorry for any inconvenience.
Ok, I’ve waited for the next oneAPI release (2023.1.0), installed it as well as the latest oneapi-for-nvidia-gpus-2023.1.0-cuda-12.0-linux.sh available here (thanks for swiftly providing the updated version).
However the problem is still there:

Am I doing something wrong? Thank you very much for your help!
Unfortunately, these headers are still only shipped with the dpcpp-ct tool and not with the main compiler. Apologies for the inconvenience. However, since both are part of the oneAPI Base Toolkit, there is a workaround possible. The main compiler can be pointed to the other installation of header files with the flag:
