Unnable to build to UWP

[Nuno-Monteiro]

Hello! Super excited about this repo and being able to access camera stream on HLL2. I managed to compile the dll's for all architectures (altough I had to edit UWP.vcproj and delete the requires module line about Cpp.WinRT) However I'm having a very weird issue building the UWP proj from Unity (2019.4.1f1).

The error is: IOException: Failed to copy C:\Program Files\Unity\Hub\Editor\2019.4.1f1\Editor\Data\il2cpp\external\bdwgc\libatomic_ops\src\atomic_ops\sysdeps\loadstore\char_acquire_release_volatile.h to C:\Users\NunoMonteiro\Documents\test\UnityPluginCollection-master\CameraCapture\CameraCapture\UnitySample\CameraCaptureApp\Temp\StagingArea\Il2CppOutputProject\IL2CPP\external\bdwgc\libatomic_ops\src\atomic_ops\sysdeps\loadstore\char_acquire_release_volatile.h: The system cannot find the path specified.

The most bizarre thing is that if I copy and paste this path on explorer I can open the file!

Did you ever get this issue? What am I doing wrong?

Cheers!

Instead of removing Cpp.WinRT, download this and then build again.

as @cwule said, try to download the C++/WinRT extension. if that did not reslove the issue try these steps:

• take the project to a different location that has a very short path.
• check your disk capacity
• check if the file is accessible (avoid working in preserved locations)

correct, you should be on the latest VS2019 and ensure you have the cppwinrt extension installed from Visual Studio. There is also a Nuget package that you may not have. Right-click the solution and select "Manage Nuget Package"
