Chapter 8. Graphics Drivers

libglvnd-1.7.0

Introduction to libglvnd

The libglvnd package provides OpenGL implementations that dispatch API calls to a given driver vendor. Some of the libraries are simply wrappers to the main dispatcher.

Installation of libglvnd

Install libglvnd by running the following commands: 

mkdir build &&
cd    build &&

meson setup --prefix=/usr       \
            --buildtype=release \
            -D gles1=false      \
            -D hgl=false        \
            .. &&

ninja

Now as the root user: 

ninja install

lib32 Installation of libglvnd

Install lib32-libglvnd by running the following commands: 

rm -rf * &&
CC="gcc -m32" CXX="g++ -m32"         \
PKG_CONFIG_PATH=/usr/lib32/pkgconfig \
meson setup --prefix=/usr            \
            --libdir=/usr/lib32      \
            --buildtype=release      \
            -D gles1=false           \
            -D hgl=false             \
            .. &&

ninja

Now as the root user: 

DESTDIR=$PWD/DESTDIR ninja install    &&
cp -vr DESTDIR/usr/lib32/* /usr/lib32 &&
rm -rf DESTDIR                        &&
ldconfig

Command Explanations

[Note]

Note

Inspect meson_options.txt or meson.options for a full list of options.

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-D gles1=false: This disables an obsolete version of OpenGL ES.

-D hgl=false: This disables targetting Haiku by default as this guide is for Linux, not Haiku.

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

Short Descriptions

libEGL

contains EGL window-system API functions

libGL

is the “legacy” OpenGL library; wrapper library calling libGLdispatch and libGLX

libGLESv2

exposes OpenGL ES 2.x and 3.x entrypoints; wrapper library calling libGLdispatch

libGLX

dispatches GLX extensions to the right vendor

libGLdispatch

dispatches OpenGL and TLS to the right vendor

libOpenGL

is the “new” OpenGL library and exposes OpenGL entrypoints; wrapper library calling libGLdispatch
