Carla Docker (ue4-dev) LightBuild (run_container.sh, UE4 separately built): version compatibility issue (TaggedComponent.cp error)

[shubhamKGIT]

Hi,

I am trying to build Carla container with Scripts/run_container.sh (from git ue4-dev branch). The $UE4_ROOT is set in local bash environment and UE4 build is working fine in both containerized and local install. There is some issue in CarlaUE4Editor build step. Can someone please help with the issue if you also came across this.

The errors seems to be from UE4 changes for forward updates but backward compatibility for Carla broken in the process. Are there compatible UE4 and Carla branches which would make this issue stop? Please share if you know.

Thank you for your help.

Found out that if you use UE4 carla branch and then do container builds (UE4 Editor build and then a separate Carla Editor build), the issue is resolved.
