Command Explanations

--buildtype=release: This switch ensures a fully-optimized build, and disables debug assertions which will severely slow down the libraries in certain use-cases. Without this switch, build sizes can span into the 2GB range.

-D glvnd=enabled: This forces the build system to fail the configuration step if libglvnd-1.7.0 was not found. If you want to accept the risks of using this package's core OpenGL libraries and have not installed libglvnd, remove this parameter. Read About OpenGL for more information. Switching is not recommended.

-D platforms=...: This parameter controls which windowing systems will be supported. Available linux platforms are x11 and wayland.

-D gallium-drivers=auto: This parameter controls which Gallium3D drivers should be built. Gallium drivers are essentially OpenGL drivers. If you wish to build specific drivers, valid options include:

You may replace auto with a comma-separated list to build only a subset of these drivers if you precisely know which drivers you need, for example: -D gallium-drivers=radeonsi,iris,swrast.

-D vulkan-drivers=auto: This switch enables support for the Vulkan graphics API. It automatically builds all graphics drivers that are available for Vulkan. If you wish to build specific drivers, valid options include:

You may replace auto with a comma-separated list to build only a subset of these drivers if you precisely know which drivers you need, for example: -D vulkan-drivers=amd,nouveau,swrast.

-D video-codecs=all: This parameter enables building all the video codecs as they are disabled by default to avoid legal issues. It would be prudent to not distribute your build if you set this option. The matter is still unclear, however. See this Debian bug report for more info.

-D valgrind=disabled: This parameter disables the usage of Valgrind during the build process. Remove this parameter if you have Valgrind installed, and wish to check for memory leaks.

-D libunwind=disabled: This parameter disables the usage of libunwind.

-D egl-native-platform="...": This parameter controls which Embedded Graphics Library support will be built. Available linux options are auto (default), x11, wayland, surfaceless, and drm.

-D gles1=disabled: This flag disables building a deprecated spec of OpenGL ES if -D glvnd=enabled was not passed.

-D gles2=disabled: If you didn't pass -D glvnd=enabled and don't need OpenGL ES, use this option. Be sure to read the section called “About GLES (OpenGL ES)”.

-D libgbm-external=true: This links against the system-installed libgbm and disables building the GBM if it's installed. Whenever updating this package, it is recommended to also update the GBM so this option is not used.

BINDGEN_EXTRA_CLANG_ARGS="-m32": This variable ensures that rust-bindgen-0.72.1 generates bindings that don't go out of bounds when compiling lib32 Nouveau Vulkan.

sed -i 's/\/usr\/lib\//\/usr\/lib32\//g' ./build.ninja: This package can be stubborn and likes to link against LLVM libraries in /lib, even on a multilib installation, so this command tells this package to link against libraries in the proper directory.
