I have been working the universal windows platform and the HoloLens and I have been hoping to make use of a native plugin with the eventual goal of streaming video and audio. I originally used this tutorial:
Working with Native Plugins - 2019.3 - Unity Learn
Which allowed me to create a plugin which works fine on a normal windows machine. My first thought would be that you would recompile for ARM64 and have it work the same. I understand that different APIs exist, but since it was supposed to be the simplest case of adding two numbers, I was hoping it wouldn’t matter. The project builds, but when the function is seems to exit as soon as it comes to the DLL code in the build. Despite visual studio being attached no exceptions seem to be thrown so I am unsure as to what the exact issue is.
I have had a look at this:
How to: Use existing C++ code in a Universal Windows Platform app | Microsoft Learn
However, I can’t figure out how to make use of the Giraffe example. I have made a windows runtime component, but the syntax seems to link into unity seems to be different. I have the same issue with this dll in the build, so I tried to build to x64 to test in the unity editor:
I have tried this syntax for instance:
[DllImport(“GiraffeDll”)]
private static extern IntPtr Create();
To call the giraffe factory function called create which is marked with the export macro in the example code.
I get a:
DllNotFoundException: GiraffeDll assembly: type: member:(null)
UseDllGiraffe.OnEnable () (at Assets/Plugin Scripts/UseDllGiraffe.cs:38)
Am I missing something obvious here?
