Hey Patrick,
In dev version of CarlaUE4 you should not have anything related to CarlaUnreal folder as it only belongs to ue5-dev.
It seems like you have a missmatch between versions. We recommend to have carla clones two times if you wanna work with ue4 and ue5 versions.
We are gonna release a document about how to work with Carla UE5 in next weeks. For now, we suggest you to do switch branch to dev, or an specific branch, do a git clean -fdx and continue working as you were until now.
Please, do not mix 'dev' and 'ue5-dev'
Apologizes

Hi Aaron,
I didn't switch branch or use the UE5 branch.
I cloned the repository with
git clone --depth 1 -b carla https://github.com/CarlaUnreal/UnrealEngine.git /apps/UnrealEngine_4.26
a few months ago, and didn't change the UnrealEngine_4.26 file for months, too.
Jän = January
Mai = May
i did the same with the Carla source version
git clone --depth 1 -b 0.9.15 hhttps://github.com/carla-simulator/carla.git /apps//apps/carla_source_0.9.15
Jän = January
Mai = May
I did the same with Carla 0.9.15.2, but deleted the folder a week after installing it.
I can switch to the dev branch, but if the normal branch doesn't change without me updating it manually, I want to keep it that way to prevent breaking something.
I want to be sure this behavior is documented (as an issue), if someone has this kind of problem in the future.
BR,

Then this is so strange... nothing should have changed

I believe the problem is, that the files I mention before have an absolute path to the Carla source version.
At some point 2 files are generated, and it doesn't update with just using "make launch"
I can look into it a bit deeper, if I have some free time.

Sorry for being late @PatrickPromitzer.
By the way, thanks for the community contributions you are making we really appreciate it.
How do you suggest to fix this issue?

You are Welcome.
From the code I saw, I am not sure if you could stop creating the problematic file.
(I am not deep enough in the UnrealEngine code to see if you could shift it into the Carla project path. At some point I probably try to work the the C++ code itself.)
I have 3 ideas, but someone have to check witch one works
1.) Generate the files each time you need it
If it doesn't take too long, it would be the easiest way to just generate the file each time you use the make file from Carla.
As example for
- opening the Editor
- generate package
- install
...
you call a script to generate the file with the absolute path to the Carla Project.
You could just replace the "/apps/carla_source_0.9.15/" with the right path, too. (I did that to make it work)
2.) move the file into the project folder (maybe not possible)
A better way (but more complex), would be if the script is in the Carla Project folder instead of the UnrealEngine folder.
I don't think it is possible, but it would be cleaner.
3.) use a different file name for each installation
The current file has the name "Link-libUE4Editor-CarlaUE4.so.link.sh" which is pointing to the project folder.
If you have a more unique name, for example "Link-libUE4Editor-CarlaUE4-v0_9_15.so.link.sh", it would not be completely fail save, but better with different versions.
