| ''%%sudo ninja install%%'' to install Mesa system-wide | Don't bother installing libdrm from source, just do ''sudo apt install libdrm-dev'' as we say above |
| | |
| | Run the ''meson'' configure command for Mesa without the ''%%-Ddri-drivers=''%%'' option, which was removed in some recent version of Mesa since the guide was written: |
| | |
| | ''CFLAGS="-O2 -march=armv8-a+crc+simd -mtune=cortex-a72" CXXFLAGS="-O2 -march=armv8-a+crc+simd -mtune=cortex-a72" meson -Dglx=disabled -Dplatforms= -Dllvm=disabled -Dvulkan-drivers=broadcom -Dgallium-drivers=v3d,vc4,kmsro -Dbuildtype=release ..'' |

| | After building Mesa, ''%%sudo ninja install%%'' to install Mesa system-wide |
| |
| Clone https:%%//%%github.com/krh/vkcube and ''%%mkdir build%%'' and ''%%meson ..%%'' and ''%%ninja%%'' and ''%%./vkcube -m khr -k 0:0:0%%''. | Clone https:%%//%%github.com/krh/vkcube and ''%%mkdir build%%'' and ''%%meson ..%%'' and ''%%ninja%%'' and ''%%./vkcube -m khr -k 0:0:0%%''. |

| | |
| | Usually, you need to change the ''-Dvulkan-drivers'' and ''-Dgallium-drivers'' options depending on your GPU. |

| | You might need to chmod a different ''/dev/dri'' path if no Vulkan device found. |
