I just compiled UE4 from github and when I want to start UE4 Editor I get:

tomsk@Andromeda:~/UnrealEngine$ ./Engine/Binaries/Linux/UE4Editor
./Engine/Binaries/Linux/UE4Editor: symbol lookup error: /home/tomsk/UnrealEngine/Engine/Binaries/Linux/libUE4Editor-Kismet.so: undefined symbol: _ZN26FGraphEditorDragDropAction9ConstructEv

Any solution please?

Hey t0msk-

The message you’re seeing is likely related to the version of clang you’re using. Can you try switching clang to 3.8 and then run through ./Setup.sh & ./GenerateProjectFiles.sh. You may also want to download a fresh instance of the engine and do a clean rebuild as well.

Cheers

Thank you and please how can I switch to Clang 3.8? Because Setup will install Clang 3.9 automatically.

You should be able to use the command “sudo apt-get install clang-3.8” in your terminal output to install 3.8 specifically. You may want to check the following page for how to set it as default: 12.04 - Set clang-3.8 as default - Ask Ubuntu
