Hi All,
I have just migrated my Unity project from Unity **v2020.3.30f1** to **v2021.3.5f1**.
I have successfully built and run the project targeting Windows.
When I change the target platform to **Android** the build **fails** while **generating il2cpp**.
The failure seems to be caused by issues with **EasyWebCamLib.cpp**
I cannot determine whether EasyWebCamLib.cpp is an Android standard lib, a Unity standard lib or something linked in by Packages/Plugins I use in my project.
Any suggestions or help would be very much appreciated. TIA.
Regards AndyB
