Unreal Engine 4 on Debian Buster, OpenPOWER Edition

Required OS dependencies

clang-5.0 dos2unix autotools-dev automake cmake libtool libc++-dev libc++abi-dev libx11-dev libxext-dev libegl1-mesa-dev mesa-common-dev libgl1-mesa-dev libgles2-mesa-dev libglib2.0-dev libglu1-mesa-dev libxinerama-dev libxkbcommon-dev libxrandr-dev libxrender-dev libvulkan-dev libxcursor-dev libxt-dev libxi-dev libxv-dev libhdf5-dev libwebsockets-dev freeglut3-dev wayland-protocols x11proto-input-dev x11proto-randr-dev x11proto-scrnsaver-dev x11proto-xinerama-dev

Required OS setup

update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-5.0 100
update-alternatives --install /usr/bin/clang clang /usr/bin/clang-5.0 100

Required licenses

You will need to set up an account with Epic / GitHub and accept the EULA terms for access to the source code to continue. If you cannot accept the terms but still want to play Unreal Tournament 4 on OpenPOWER, the only recourse available to you would be to contact Epic and ask for them to allow release of alpha builds for OpenPOWER.

To proceed, navigate to the Unreal Engine licensing page and follow the instructions, then come back here once you have access to the source code.

Important: All of the links below for source download will return 404 unless you are logged in to GitHub with the account that has source code access enabled.

Current Status

  • Editor seems to be working properly as of GIT commit 1057ebacec3649a44bf6b5617112a12d9b9e56b0
  • OpenGL mode appears to function correctly, Vulkan mode loads but triggers a failure in the radeonsi Vulkan stack when mousing over the right hand navigational view.
  • OpenGL can run into an overflow condition with very complex scenes; this manifests as scene lights turning off / back on somewhat randomly based on what is in view. This limitation of OpenGL is supposed to be fixed in Vulkan, but Vulkan support is still at a very early stage and loads to a black screen much of the time or outright crashes.

Known Issues

  • AMD GPUs have known bugs as of Q3 2018. While we expect these to be fixed over time, in the interim the kernel and mesa need to be patched to work properly[1].
  • LLVMPipe cannot be used because it only exposes Shader Model 4 interfaces, while UE4/UT4 require Shader Model 5 or higher (or even Vulkan) to support their advanced rendering features.
