Error with "make launch"

[JDIRK3]

CARLA version: 0.9.15 Platform/OS: Ubuntu 20.04

Problem you have experienced: When I try to start carla with "make launch" after successfully do "make PythonAPI", the unreal engine editor starts, but the progress bar stops at 71%. The following errors occure:

• [2024.05.22-13.25.05:351][ 0]LogAssetRegistry: Error: Package ../../../../carla/Unreal/CarlaUE4/Content/Carla/Maps/TestMaps/EmptyMap.umap has malformed tag (and many similar errors)

Steps to reproduce: I followed the introduction https://carla.readthedocs.io/en/latest/build_linux/ with additional steps provided by other issues.

Other information (documentation you consulted, workarounds you tried): search through the other issues (in some somebody have/had the same issue in context of another issue, but no solution was provided and the issue was closed); tried ./Update.sh but got the message the content was on the newest version

same problem,is it solved?

[JDIRK3]

No, I will post the solution, if I found one.

Maybe as addition on the error messages:

I got the following Crash report from the Unreal Engine:

You have not the content available. that's why it does not work

[JDIRK3]

Ok, but i extracted the input of the content.tar.gz into the content folder under "/carla/Unreal/CarlaUE4/Content/Carla". I used the newest version of the content (20231108 or something like that). What did I do wrong?

The "/carla/Unreal/CarlaUE4/Content/Carla" has following data inside:

• Blueprints
• Carla_0.9.15
• Config
• ExportedMaps
• HDMaps
• hooks
• HoudiniEngine
• Jenkinsfile
• LICENSE
• Makefile
• Maps
• road_xodr
• Static

[JDIRK3]

I am not sure, but maybe I found the issue. Could it be, that Content.tar.gz needs to be extracted into /carla/Content?

For clarification before I meant with "Content.tar.gz" the file that needed to be downloaded and "Content" was just a placeholder for the Content-ID it's called, if I remember right

After update.sh is executed, the “content.tar.gz ” file package will be automatically extracted to the carla/content directory. Have you solved the problem “ Signal 11 caught.” now? 🥺

I installed two times content.tar.gz in different versions and at different places. After deleting both of them and running update.sh it worked. No signal 11 left.

[JDIRK3]

Solution was to completly everything new. So something must gone wrong during installation would be my guess.

[johnren-code]

I don't fully understand what you mean. What does the specific solution refer to?

I don't fully understand what you mean. What does the specific solution refer to?

I suppose you need to re-run the ./Update.sh correctly, so that we have a complete Content folder
