</code>

First time
<code bash>
# clone
git clone https://github.com/NvPhysX/UnrealEngine.git

# complete download of dependencies and binaries
cd UnrealEngine
./Setup.sh
./GenerateProjectFiles.sh
</code>

build editor
<code bash>
make ShaderCompileWorker UnrealLightmass UnrealPak CrashReportClient UE4Editor
</code>

To running editor an IDE must be present, Epic wants kdevelop but it is possible to use [[https://wiki.unrealengine.com/Linux_Known_Issues|others]].

For example configure vim IDE for C++ editor mode: 
1) clone
<code>
cd Engine/Plugins/Developer
git clone https://github.com/fire/SensibleEditorSourceCodeAccess.git
</code>

2) edit '''Engine/Config/Linux/LinuxEngine.ini'''
<code>
[/Script/SourceCodeAccess.SourceCodeAccessSettings]
PreferredAccessor=SensibleEditorSourceCodeAccessor
</code>

run editor
<code>
Engine/Binaries/Linux/UE4Editor
</code>
