Beyond Linux® From Scratch (System V Edition) - Version 11.2

Chapter 24. Graphical Environments

Mesa-22.1.7

Introduction to Mesa

Mesa is an OpenGL compatible 3D graphics library.

[Note]

Note

Mesa is updated relatively often. You may want to use the latest available 22.1.x mesa version.

This package is known to build and work properly using an LFS-11.2 platform.

Package Information

Additional Downloads

Mesa Dependencies

Required

Xorg Libraries, libdrm-2.4.112, and Mako-1.2.1

Recommended

libva-2.15.0 (to provide VA-API support for some gallium drivers, note that there is a circular dependency. You must build libva first without EGL and GLX support, install this package, and rebuild libva), libvdpau-1.5 (to build VDPAU drivers), LLVM-14.0.6 (required for Gallium3D, nouveau, and radeonsi drivers and for swrast, the software rasterizer which is sometimes referred to as llvmpipe. See https://docs.mesa3d.org/systems.html for more information), and wayland-protocols-1.26 (required for Plasma-5.25.4, GNOME, and recommended for GTK+-3.24.34)

Optional

libgcrypt-1.10.1, libunwind-1.6.2, lm-sensors-3-6-0 , Nettle-3.8.1, Valgrind-3.19.0, mesa-demos (provides more than 300 extra demos to test Mesa; this includes the same programs added by the patch above), Bellagio OpenMAX Integration Layer (for mobile platforms), libtizonia, and libvulkan

Installation of Mesa

If you have downloaded the xdemos patch (needed if testing the Xorg installation per BLFS instructions), apply it by running the following command: 

patch -Np1 -i ../mesa-22.1.7-add_xdemos-1.patch

Install Mesa by running the following commands: 

mkdir build &&
cd    build &&

meson --prefix=$XORG_PREFIX   \
      --buildtype=release     \
      -Dplatforms=x11,wayland \
      -Dgallium-drivers=auto  \
      -Dglx=dri               \
      -Dvalgrind=disabled     \
      -Dlibunwind=disabled    \
      ..                      &&

ninja

If you built the tests (see 'Command Explanations'), to run them issue: ninja test.

Now, as the root user: 

ninja install

If desired, install the optional documentation by running the following commands as the root user: 

install -v -dm755 /usr/share/doc/mesa-22.1.7 &&
cp -rfv ../docs/* /usr/share/doc/mesa-22.1.7

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.

-Dgallium-drivers="...": This parameter controls which Gallium3D drivers should be built.

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

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

-Dvalgrind=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.

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

-Dbuild-tests=true: This switch will cause the test code to be enabled.

-Dvulkan-drivers=...: This switch allows choosing which Vulkan drivers are built. Since BLFS does not use Vulkan, it is safe to leave the list of Vulkan drivers empty. The default is auto.
