Environment

  • UE 4.27.2 (Launcher)
  • RuntimeImageLoader (commit 3bb5ed5)

What went wrong

Packaging for Android (ASTC) resulted in an undefined symbol error if the OculusVR plugin is disabled.

UATHelper: Packaging (Android (ASTC)):     ld.lld: error: undefined symbol: FRuntimeTiffLoadHelper::FRuntimeTiffLoadHelper()

How to Recreate The Issue

  • Create a new blueprint project from 4.27.2 (Launcher)
  • Close the Editor
  • Import RuntimeImageLoader to the Plugins folder (from commit 3bb5ed5)
  • Open the project and build the binaries for RuntimeImageLoader
  • Disable the OculusVR plugin and restart the editor
  • Attempt to package for Android (ASTC), but it fails
  • To verify, enable the OculusVR plugin and repackage and it will succeed.

I have a separate project and enabling OculusVR did not resolve the error, but so far this was how I found out that I could recreate the error from a new project.

It seems that TIFF format is not supported on Android so I made necessary changes
