    Can anyone help. Im quite a novice and have run into this error. It plays fine in the player and everything works but when i try ti build the apk for the oculus quest, i get the following errors. Its only a basic 3 scene app with a walk through of some environments using photon.

    IL2CPP error for method 'System.Void POpusCodec.OpusDecoderAsync`1::DataCallbackStatic(System.IntPtr,System.IntPtr,System.Int32,System.Boolean)' in OpusDecoder.cs:155

    This appears to be failing to build in the Photon Voice package. You might consider copying your project and removing it to test a build, and/or I would recommend contacting the package authors.

    I have a similar error trying to build for webGL if you could help. Here is the error:

    There should be additional information in the editor log (or maybe the editor console) about this error message. This part of the message is pretty general, and does not let us know what caused the error.

    Could to track down that additional information and post it here?

    It looks like there might be a problem locating or running python on this machine, which is required to run the Emscripten C++ compiler.

    Does /usr/bin/python exist and work on this machine?

    Thanks for looking into this!

    It doesn't exist on usr/bin nor is it default directory with new versions of mac OS as it is a security issue. I tried creating a sym link without success. Can I change target location from Unity somehow?

    In Unity < 2021.2 (iirc if I am not messing up my memory on the versions), Unity used to rely on Apple to ship Python as part of macOS. Like Josh mentions above, /usr/bin/python is one of the paths that is looked up, and also iirc anything in PATH should be looked for as last resort.

    In Unity 2021.2, with Emscripten 2.0.19.6-unity, Emscripten updated to Python 3, and we migrated to bundling Python 3 as part of the WebGL package, which fixed Unity to no longer depend on macOS system python.

    In Unity 2022.2, Unity updated to Emscripten 3.1.8-unity, which streamlined the Emscripten SDK installation with WebGL package.

    Apple dropped shipping built-in Python 2 in a newer OS update macOS 11.0 (iirc?) when Apple M1 chips came out, which broke Unity < 2021.2 to no longer be able to build to WebGL out of the box on macOS.

    To fix that issue, Unity retrofitted the Emscripten installations on Unity < 2021.2 to also explicitly ship Python, but I am not 100% on which Unity versions have that backport fix. Should be in all tech streams, but maybe there was a gap somewhere.

    So to troubleshoot, try testing Unity 2022.2 and then Unity 2021.2. If those work for you out of the box, then it is likely the issue is about missing bundled python. If those don't work either, then the issue is probably something else that is a bit more subtle.

    You can also try doing a subdirectory search inside the Unity Editor directory, and see if there is a 'python' executable in there to see if your particular version of Unity has come with a bundled python, or if it is expecting a system installed version. If you haven't already, updating to latest point release of your editor tech stream might also help.

    Thanks for all this info. I followed the advice to add a prebuild scrip from https://forum.unity.com/threads/cas...d-unity-2020-3-constant-build-errors.1255419/ and now I'm getting issue below:

    Good - now Emscripten is found correctly, and the generated C++ code is compiling.

    This failure occurs because the code in the project has extern methods in C#. Methods marked as extern with a the [Dllimport("__Internal")] attribute must be present in a native library that is linked with the Unity player when building with the IL2CPP scripting backend.
    For example, this in this project one function which causes this issue is named: CapturePixelData
    You have two options:

    1. Build a native library with all of the methods marked as extern with the [Dllimport("__Internal")] attribute for the target platform and architecture of the player. See this documentation for details about native plugins: https://docs.unity3d.com/Manual/NativePlugins.html

    2. Remove the C# code which defines this extern method. You can do that with platform dependent compilation: https://docs.unity3d.com/Manual/PlatformDependentCompilation.html
