Wrong place for clang ?

Hi,
Seems that on Ubuntu, clang is not well extract..

I tried to edit SetupToolchain.sh in Linux directory but still no change

Hi,
It seems I have the same issue. When looking at /tmp/dbuild-unreal_engine_4.log, it raises a lot of warnings (I only include one of them but the list is very long)

Step 36/48 : RUN cd /local/UnrealEngine && ./GenerateProjectFiles.sh
 ---> Running in 1332dc350b74
Attempting to set up UE4 pretty printers for gdb (existing UE4Printers.py, if any, will be overwritten)...

WARNING: Exception while generating include data for UE4Editor: Unable to build: no compatible clang version found. Please run Setup.sh
WARNING: Exception while generating include data for BlankProgram: Unable to build: no compatible clang version found. Please run Setup.sh

I guess this is the cause of the final error I get:

Any idea how I can fix that?

Thanks!

As a trick, I change the path of extraction of clang in the script files
Contact me if you got other issue.

[Roman-Malinowski]

Hi Tom,
Thank you for your response. I can't figure out where to change the clang extraction path, could you provide me some insight on the files you modified and the new path you specified?

Thanks

Hi,
Has mentioned above, it is that file that could be hack :
DroneSimLab/dockers/unreal_engine_4/UnrealEngine/Engine/Build/BatchFiles/Linux/SetupToolChain.sh

and I edit the TOOLCHAIN_CACHE=../ue4-sdks/

I create an hotfix based on the 4.23.0 release on my fork

[Roman-Malinowski]

Thanks a lot!

[tomlogan501]

@Roman-Malinowski Did you succeed ?

[Roman-Malinowski]

Hi Tom,

Thank you for asking!
Actually I can't make it work, I have issues when building Unreal with your version. Like before, it delays some install because apt-utils is not yet installed, and the final error I get is the one bellow.
Any idea on how to fix this?
In any case, thank you for your help!

Hmm try to delete the docker image to start from new, did you use your own computer or a CI job ?
I have no more errors on the job I deploy but i will verify the image before the demo.
