Unity Build with MRTK + OpenXR + Acoustics fails due to dependency issues

[jmfranz]

From the demos of acoustics 2 I thought it should be compatible with HL2 builds; however, the build fails due to missing numerics.vectors dependency.

Unity Version: 2020.3.16f1 MRTK Version: 2.7 Acoustics: Latest on aka.ms

Error message:

Fatal error in Unity CIL Linker
Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'System.Numerics.Vectors, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null'

Hey @jmfranz can you provide a bit more information? Does the project work in-editor at all? Are you targeting ARM or ARM64 for the HoloLens build?

We tried this internally and don't see the missing System.Numerics.Vectors issue, although we have seen #65

Hi @MikeChemi, it works in the editor. I've downloaded the sample again today and added it to an empty project together with the MRTK and OpenXR.

Unity 2020.3.15f2 Target HoloLens on ARM64 SDK set to 10.0.19041.0 on Release It fails with Net 4.x and Standard 2.0 Here is the full error:

Thanks for the additional information. Off-hand, I'm surprised to see this, since we only need the managed DLLs for in-editor baking. If anything, I'd expect the editor to have issues, but the build-for-device to be OK.

We'll dig in on our side, but I don't have a good estimate of when we'll have more information to share. In the meantime, you can try deleting the entire Acoustics/Editor folder prior to building for HoloLens, since that is where all the managed code lives which shouldn't be necessary for deploying Project Acoustics to the HoloLens.

@MikeChemi thanks for the suggestion. Confirming no issues compiling after deleting the Editor folder.

To be honest, I thought Unity would ignore everything in the Editor folder during a build.

Thanks!
