anybody help?

3

I suspect that the C++ compiler from the Android NDK cannot be located properly. Please confirm that the Android NDK is installed. It should be possible to install the NDK from the Unity Hub.

4

Android NDK is already truly located. I didn’t get it why gives this error

5

Maybe try to re-install the NDK and Unity then. I’m not sure where Unity is looking for the NDK in this case, but it seems to be the wrong place.

now giving this error

I’m not sure what this error means. @Tomas1856 can you help?

8 
android.defaultConfig.versionCode is set to 0, but it should be a positive integer.

Please make your version number a positive number in PlayerSettings

9

R8 issue is happening because of API Target 31

10

That’s a warning, it shouldn’t block you. Check the version code.

11

it is because of API 31. I did API 30 and fixed. Also, why does r8 appear active in gradle template when it is not in player settings? it is ridiculous

Unity 2020.3.28f1 WebGL build failed on macOS Monterey 12.3

I have the same problem.

14

This seems like a different issue from the one reported in this thread originally, as the original discussion was about and Android player build.

However, I suspect that the issue here has something to do with the Emscripten installation. Do you happen to have Emscripten installed separately on this machine? Unity should ship with its own Emscripten installation that works, but I wonder if IL2CPP is picking up a different one.

15

The same thing is happening to me (not the Android build) but just building out this project in general. I created a thread for it here .

16

i just updated my mac to 12.3.1 and now showing this! Did you fixed it? if yes how?

17

same here.

18

For the WebGL build I’m getting the same (also running OSX Monterey 12.3) and @JoshPeterson I’m running 2020.3.32f1 and have not installed any additional ECMA Script stuff. This is a new computer with only Unity installed, GIMP and Blender. Very plain vanilla. Let me know how to analyze multiple IL2CPP issues and I’d be happy to do the leg work.

Hi guy,
Try to create class in Asset folder with name “WebglPreBuildProcessing” and script as below. Note that: the path should change for current python version: Versions/3.10/bin/python3.10

Then build again. Hope to resolve this case

  • #if UNITY_EDITOR
  • using UnityEditor.Build;
  • using UnityEditor.Build.Reporting;
    • public class WebglPreBuildProcessing : IPreprocessBuildWithReport
  • {
  • public int callbackOrder => 1;
  • public void OnPreprocessBuild(BuildReport report)
  • {
  • System.Environment.SetEnvironmentVariable(“EMSDK_PYTHON”, “/Library/Frameworks/Python.framework/Versions/3.10/bin/python3.10”);
  • }
  • }
  • #endif

Hi guys, I’m having the same issue and I also running OSX Monterey 12.3.1. Did anyone have any idea of how to solve this problem?
