Linux engine compilation error: "libUE4Editor-SequenceRecorder.so: file not recognized: File format not recognized"

When trying to compile the release branch of the engine, I get following error:

.../UnrealEngine/Engine/Binaries/Linux/libUE4Editor-SequenceRecorder.so: file not recognized: File format not recognized

Setup.sh and GenerateProjectFiles.sh ran without any problems.

System: Xubuntu 17.10

Did you interrupt (e.g. Ctrl-C or anyhow else) your compliation previously? Also, is it a new repo or was it previously used with different engine versions?

In either case I suggest removing that file and rebuilding.

that was it. I had to interrupt the compilation in the middle. Deleting the file worked. thanks!
