Nvidia Jetson Nano UE4LinuxArm64Vulkan screenshot
If you turn off AmbientOcclusion and do some tweaks on scalability settings, set the resolution to 720p (ex: 1080p fullscreen set r.ScreenPercentage to 50) it can run Unreal Engine blank project template at 60fps on Nvidia Jetson Nano. If something fails, read the Errors and Fixes below. If everything worked, it will create an Linux Arm64 package. Try to package your project to Linux in UE4. project file, “Switch Unreal Engine Version” and make sure it’s using your UE4 compiled source code.Ĭreate an environment variable LINUX_MULTIARCH_ROOT with the folder path to your clang++ v8 directory containing the multiple linux architecture directories.Ĭreate an environment variable of UE4_LINUX_USE_LIBCXX to 0. Or TargetArchitecture=ArmUnknownLinuxGnueabihf (for Linux Arm 32bits OS). TargetArchitecture=AArch64UnknownLinuxGnueabiĬhange TargetArchitecture to TargetArchitecture=AArch64UnknownLinuxGnueabi Static private string DefaultArchitecture = “aarch64-unknown-linux-gnueabi” Ĭhange aarch64-unknown-linux-gnueabi to arm-unknown-linux-gnueabihf if you want to build packages to Linux Arm 32bits OS (like Raspberry Pi, Asus Thinkerboard and others SBCs).Įdit your UE4Project\Config\DefaultEngine.ini, find or add the following lines :
static private string DefaultArchitecture = “aarch64-unknown-linux-gnueabi” static private string DefaultArchitecture = “x86_64-unknown-linux-gnu” Static private string DefaultArchitecture = “x86_64-unknown-linux-gnu” …/UnrealEngine/Engine/Source/Programs/UnrealBuildTool/Platform/Linux/UEBuildLinux.cs Unzip and copy aarch64-unknown-linux-gnueabi to clang8\aarch64-unknown-linux-gnueabi. Unzip and copy arm-linux-gnueabihf to clang8\arm-unknown-linux-gnueabihf. ĭownload the Unreal Engine 4 Linux-x86_64 cross compile toolchain binaries from ĭuplicate the arm-unknown-linux-gnueabihf to another folder named aarch64-unknown-linux-gnueabi. Unzip all folders (bin, include, lib, etcs) to clang8\arm-unknown-linux-gnueabihf. Install the additional CLang8 package for Linux ARM architeture from Be careful with spaces on your folder name or paths because it can cause troubles later. Preparing to cross-compile to Linux ARM : I used this tutorial, it’s outdated and it breaks with newer UE4 versions: You need access to Unreal Engine 4.23.1 Source Code, download it and build it one time to assure everything is working. This are my old notes about “HowTo_UE4_LinuxArm64.txt”, I’m saving and sharing here if anyone else wants to try.
