Converting from MSVC to DPC++ 2023.1

Hi,

I try to convert my existing application to DPC++ 2023.1. I switch the toolset in the project properties of vs2022 and added the line:

#include <sycl/sycl.hpp>

to allow some sycl function calls in the future. The I compile and line - without any issue - except that it took much longer than MS v143.

But as soon as i try to debug the console app i got the message:

I tries to avoid this by copying the missing file from the intel oneapi folder into my app folder and the next dll was missing. Since I cannot belief that this is the way to go i guess I'm doing something wrong here.

Can someone shed some light on this and let me know how DPC++ is supposed to be used in the VS2022 IDE?

Thanks,

Daniel

Rebooting fixes this problem (sometimes) - very strange. Now I have the problem again. It seems to be fixed after reboot, but after a second report the problem reappeared.

copied the sycl6d.dll into C:\Program Files (x86)\Intel\oneAPI\compiler\latest\windows\redist\intel64_win\compiler fixes the problem that the app cannot run. unfortunately it seem not to be the correct solution sine non of the sycl functions returns a useful result.

creating/compiling the DPC++ console sample that s installed into the VS project templates works without any issues. The problem seems to be the converted MSVC solution.

The problem happens if you have a solution that contains some projects. If you set the startup project to a non-DPC++ project - that still uses a DPC++ project (maybe load a shared lib) the sycl6d.dll is not found. Setting the startup project to a project that is build with DPC++ all is fine.
