Compiling Version 2.4.0 fails for all build targets except standalone and android

[Marbl70]

When importing the latest version 2.4.0 into Unity where the build target is set to WebGL or iOS or anything except standalone and android there are a number of errors in the console, preventing builds.

..
Library\PackageCache\com.htc.upm.vive.openxr@3dd72f5\Runtime\CompositionLayer\Scripts\CompositionLayerPassthroughAPI.cs(641,22): error CS0161: 'CompositionLayerPassthroughAPI.SetPassthroughLayerType(int, LayerType, uint)': not all code paths return a value
...

In those functions there is an ifdef missing:

#if !(UNITY_STANDALONE || UNITY_ANDROID)
return false;
#endif

This prevents us from using this version of the sdk as we are building for multiple targets, please fix asap.

Thanks,
Martin

Thanks for the feedback. We'll fix in next release.

👍 for fixing this in the "next release". For anyone who finds there way here, the solution is as follows: go into PackageCache, take the imported codebase, pull it into your Packages folder, and update manifest.json as follows:

"com.htc.upm.vive.openxr": "file:./com.htc.upm.vive.openxr"

This way, you can go into CompositionLayerPassthroughAPI.cs and modify it as needed. In my case, the modification was to add something like this to each of the functions that otherwise lack return values:

#if UNITY_IOS
    return false;
#endif

Cheers.

Just updated to 2.5.1 and the issue is still there? It is really an easy fix, just put a "return false" at the end of those functions...

Pulling the code from PackageCache is a workaround but requires to make it a custom package and check it into our git source control - which is not nice.
