Linux standalone sharedassets are corrupted

[wassx]

Does this affect the legacy HoloToolkit (master) or the Mixed Reality Toolkit (mrtk_release)? Mixed Reality Toolkit

Describe the bug Building a minimal scene for linux standalone with build target Linux64. In the scene (and project) there is just a mixedrealityplayspace with a camera (tagged) and the mrtk. Everything compiles and looks fine. When starting the standalone app (in my case done in a docker container) the Player.log is filled with

This error messages spams the log. Cleaning the build folder, library,... did not work. This error occurs every 95% of builds/launches.

Thanks for the report.

Could you try going back a few commits and see when this was introduced?

Have you also been able to reproduce this for other platforms like windows or osx?

[wassx]

I tried with a version shortly after vnext_beta, same issue. Can only reproduce with linux64. Will try to step back and find latest working version.

[StephenHodgson]

Much appreciated.

Oh man that was quite some digging. Dating back to 27.10.2018 PR https://github.com/Microsoft/MixedRealityToolkit-Unity/commit/7eca8c5e668f4abc2162e28bfdfed051fd2a6cb6 still works. The issue occurs with: https://github.com/Microsoft/MixedRealityToolkit-Unity/commit/5d2f3064448941de761fa5fd3c326e8cdd1cd98f Maybe the Microsoft.MixedReality.Toolkit.Core.Utilities.Editor.Setup.dll? Is there somewhere the source of this dll to link to?

[StephenHodgson]

Hmm that's odd. It's just an editor dll. Shouldn't get into the build at all.

[wassx]

I removed the dll (see attached patch for latest mrtk_dev at commit https://github.com/Microsoft/MixedRealityToolkit-Unity/commit/49f5c4c22b66a7e2c212f15b982056dcb31ff4cd) and now it builds and runs without these sharedassets exceptions. Removal_of_editor_setup_dll.zip

@wassx the source code can be found here

It's still in the folder with the dll, but it's been hidden by the editor with a period. Just delete the dll and rename the file without the prefixed period and it'll show back up.

Not sure that's the source of the problems tho, as it only changes the project settings and should never make its way into a final build.

[StephenHodgson]

@wassx were you also using a headless build process for linux?

[wassx]

@StephenHodgson Hi sorry for late reply, notifications didn't went through. Yes, always started a headless linux.

[StephenHodgson]

Okay, then this is def related to #3192

[david-c-kline]

This is likely fixed as we no longer use a precompiled editor setup dll
