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

Please use the following table to download the appropriate toolchain:


UE4 Version	Toolchain
4.27	-v19 clang-11.0.1-based
4.26	-v17 clang-10.0.1-based
4.25	-v16 clang-9.0.1-based
4.23 and 4.24	-v15 clang-8.0.1-based
4.22	-v13 clang-7.0.1-based
4.21	-v12 clang-6.0.1-based
4.19 and 4.20	-v11 clang-5.0.0-based
4.18	-v10 clang-5.0.0-based
4.16 and 4.17	-v9 clang-4.0.0-based
4.14 and 4.15	-v8 clang-3.9.0-based
4.11 thru 4.13	-v7 clang-3.7.0-based
4.9 and 4.10	-v6 clang-3.6.0-based
4.8 and earlier	-v4 clang-3.5.0-based

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.

Troubleshooting

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):
