Linux Support for ARKit / LiveLink

Unreal Engine 5.1.0, 5.1.1
OS: Arch Linux, Ubuntu 20.04

The issue happens on all version platform combinations as above.

When having a project with ARKit and Livelink enabled I try to get the iphone app show up as Source in Livelink.
This works flawless on a Windows setup, but on Linux I can’t make a source show up at all.

  • I configured UDP Messaging as recommended for a particular network adapter. (also remove all netwok interfaces but one)
  • I confirmed I can receive the UDP traffic on port 11111 using wireshark or for testing purppose a custom parser for the livelink data.
  • I checked that the UDP port 11111 is available and also reconfigured the configuration to a different port for testing.

I also tried to create a preset from the source as it appears on Windows - and the opened the project in Linux.
I then get:

[2023.02.09-13.11.29:868][ 1]LogLiveLink: Warning: Create Source Failure: The factory is not defined.
[2023.02.09-13.11.29:868][ 1]LogLiveLink: Warning: Create Subject Failure: The source doesn’t exist.
[2023.02.09-13.11.29:868][ 1]LogLiveLink: Error: Could not apply ‘LiveLinkPreset /Game/MyLiveLinkPreset.MyLiveLinkPreset’

It seems it just won’t run on Linux at all.

Hi, have you solved this problem? I met this problem on windows11 environment like i can’t load the live link preset created before
