Building on iOS still not possible #71

Closed EtharBuildBot closed 1 year ago

EtharBuildBot commented 1 year ago

When building in Unity for iOS an issue is raised (see below) however a build is still generated:

'''text EntryPointNotFoundException: arwRegisterLogCallback assembly: type: member:(null) PluginFunctionsARX.arwRegisterLogCallback (PluginFunctionsLogCallback lcb) (at Assets/artoolkitX-Unity/Scripts/PluginFunctionsARX.cs:106) ARController.OnEnable () (at Assets/artoolkitX-Unity/Scripts/ARController.cs:425) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&) (at /Users/bokken/build/output/unity/unity/Modules/IMGUI/GUIUtility.cs:189) '''

However, when trying to build using Xcode on Mac, the screen simply renders pink and no camera feed is displayed:

I was plagued by this error (EntryPointNotFoundException) for a day and now after updating Unity to 2021.3.25f1 I can't reproduce it. What version are you using?

philip-lamb commented 1 year ago

Closing as not able to be reproduced with current build.

philip-lamb commented 1 year ago

OK, so it looks like conditions for this to be triggered include updating the native iOS plugin after doing at least one previous build. Clearing the Unity project Library folder resolved the issue. So I would speculate that Unity is doing some caching of plugin symbols on iOS, and when the libARX.a file changes, it can't find the new symbol addresses using the old cache.

philip-lamb commented 1 year ago

This turned out to be a bug that was triggered by some recent version of Unity changing how it handles calls to plugin functions when iOS is selected. Fixed by #76
