Hello All,
I’m trying to get the hang of UE4 for an AI/simulation project and I’m running into some issues with the build environment in Ubuntu Linux (16.04).
The problem:
If I build the project using the command line UnrealBuildTool and then run the generated executable, I get a segfault with the following error:
Fatal error: [File:/home/charlesrwest/cpp/projects/UE4/UnrealEngine/Engine/Source/Runtime/Core/Private/Linux/LinuxPlatformMisc.cpp] [Line: 455]
Error copying clipboard contents: Video subsystem must be initialized to set clipboard text
However, if I package the project with the UE4 editor then run the resulting executable (without any code change) then it works fine. Does anyone know either what I am doing wrong or how to fix this issue? I would very much prefer to develop in a manner where I get error messages and/or can remote.
Command line compilation:
(Showing debug, also did development and shipping)
/bin/sh -c 'mono ../../UnrealEngine/Engine/Binaries/DotNET/UnrealBuildTool.exe TestFirstPerson Linux Debug -project="/home/charlesrwest/cpp/projects/UE4/TestFirstPerson/TestFirstPerson/TestFirstPerson.uproject"'

Running the packaged version of development without problems:

Somewhat similar to this issue, but their fix did nothing:
