Cross-compiling makes it possible for game developers to target Linux from Windows. At this time, cross-compiling is only supported for Windows, and Mac users currently have to resort to native compiling. Additionally, we support, test, and provide libraries and toolchains for the Linux-x86_64 platform.

If you are developing your project with Unreal Engine, version 4.13 (or older), refer to the Cross-Compiling for Linux (Legacy) documentation.

Why Cross-Compilation

Cross-compilation makes it possible for game developers, working in a Windows-centric workflow, to target Linux. At this time, cross-compilation is only supported for Windows. Mac users currently have to resort to native compilation. We support, test, and provide the libraries and toolchains for the Linux-x86_64 platform.

Getting the Toolchain

  • For toolchains -v8 through -v13 , there is no need to extract files or set the environment variable — just run the installer package.

  • For toolchains -v4 through -v7, we also provide the libraries and toolchains that enable you to compile for Linux ARM (original Raspberry Pi and up).

    • Note that this will require you to make a (minor) code change in UnrealBuildTool (UBT).

  • We currently have driver support for AMDGPU-PRO (not RADV) for users running Unreal Engine on CentOS.


To verify your current setup, run %LINUX_MULTIARCH_ROOT%x86_64-unknown-linux-gnu\bin\clang++ -v from the Command Prompt, which should display "clang version X.X.X ..." (see below):
