I built UE4 from branch 4.23 on Ubuntu 16.04 and followed the directions for Qt Creator integration from here and step 6.9 (running CPP project) fails – Qt Creator reports in the compile output that build succeeded but the application output shows the following error:
14:38:02: Starting /home/jeffreycreswell/apps/UnrealEngine/Engine/Binaries/Linux/UE4Editor "/home/jeffreycreswell/Documents/Unreal Projects/DrivingCPP_Prj/DrivingCPP_Prj.uproject"... 14:38:02: Failed to start program. Path or permissions wrong? 14:38:02: /home/jeffreycreswell/apps/UnrealEngine/Engine/Binaries/Linux/UE4Editor exited with code -1 14:38:02: The process failed to start. Either the invoked program "/home/jeffreycreswell/apps/UnrealEngine/Engine/Binaries/Linux/UE4Editor" is missing, or you may have insufficient permissions to invoke the program.
The path is fine and the permissions are
-rwxrwxr-x 1 jeffreycreswell jeffreycreswell 405480 Sep 6 19:11 UE4Editor
which should be fine; I’m able to launch the editor without issue from terminal or a desktop entry.
What could be going wrong?
