Build Instructions

Latest tested commit: b723962418cee94070997fd8c15548dfeebf88ee

1. Open Git Bash
2. In any directory you like: git clone https://gitlab.freedesktop.org/mesa/mesa.git; mkdir mesa/flibitBuild
3. Close Git Bash
4. Extract contents of Win flex-bison to a conveniently-located folder, add said folder to $PATH
5. Open an appropriate Developer Command Prompt
   • For PC: x64 VS Developer Command Prompt
   • For console: Xbox One Gaming Command Prompt or Scarlett Gaming Command Prompt
6. py -m pip install mako
7. cd to mesa/flibitBuild/ folder

For PC...

8. meson .. -Dgallium-drivers=d3d12 -Dgallium-d3d12-video=disabled -Dzlib=disabled --backend=vs
9. msbuild mesa.sln /m (or build with Visual Studio)

For console...

8. Write this to a file called gdkx.txt:

[target_machine]
system = 'Gaming.Xbox.XboxOne.x64'
cpu_family = 'x86_64'
cpu = 'x86_64'
endian = 'little'

Pay very close attention to the system property! Adjust this if you are building for Scarlett!

9. meson .. -Dgallium-drivers=d3d12 -Dgallium-d3d12-video=disabled -Dzlib=disabled -Dc_winlibs=[] -Dcpp_winlibs=[] --backend vs --cross-file gdkx.txt
10. Build flibitBuild/mesa.sln with Visual Studio

Final Packaging

These are the files you want to make the full D3D12 driver:

• mesa/flibitBuild/src/gallium/targets/libgl-gdi/opengl32.dll
• mesa/flibitBuild/src/gallium/targets/wgl/libgallium_wgl.dll
• PC Only: dxcompiler.dll and dxil.dll, from the DXC release you downloaded

Enjoy!

Open the generated project files in Visual Studio and use the Configuration Manager to add a new solution platform for the Gaming.Xbox platform you want, otherwise it will not work. I don't know of any automated way to make this fix.
