UE4.25 - Sample Project - AvatarSamples.uproject - Build Error: lOVRLipSyncShim

[andrewtek]

Hi All,

I am trying to build the sample project AvatarSamples.uproject. I am using Unreal Engine 4.25, built from Oculus' GitHub repository: https://github.com/Oculus-VR/UnrealEngine.

The error I am seeing when building is: 

LogPlayLevel:     [598/599] AvatarSamples-armv7.so
LogPlayLevel: Error:     ld.lld: error: unable to find library -lOVRLipSyncShim
LogPlayLevel: Error:     clang++: error: linker command failed with exit code 1 (use -v to see invocation)

I was looking for documentation for this sample project, but this particular sample is not even mentioned:
https://developer.oculus.com/documentation/unreal/unreal-samples/

Any help would be greatly appreciated! Thanks!

Oculus, please fix 4.25 avatar and lipsync

It's a known bug, but yeah, I'd love them to fix it asap.

Hi Motorsep! Long time no chat. Do you know of a way I can build the avatar sample project without the lipsync shim? Thanks!

[motorsep]

I have no idea, sorry. I don't use Avatars.

Hi,

Haven't tried this myself, but from your posted error it looks like you're trying to build the older 32-bit Android executable (armv7).

It doesn't look like AvatarSamples is configured to build Android as-is, have you tried unchecking armv7 and checking just arm64 under the Android build settings?

Thanks en-austin. I looked at https://developer.oculus.com/blog/oculus-developer-release-notes-v17/ and saw this:

Oculus Lipsync version 1.43 is not compatible with Unreal Engine 4.25. To use Lipsync, you must use an older version of Unreal Engine.

My guess is that Oculus is working on it and we will see an update before too long.
