Platform Plugin Dependencies▲
On Linux, the xcb QPA (Qt Platform Abstraction) platform plugin is used. It provides the basic functionality needed by Qt GUI and Qt Widgets to run against X11. Its library dependencies are described the following table. To build Qt from its source code, you will also need to install the development packages for these libraries for your system.

Development packages for these libraries contain header files that are used when building Qt from its source code. On Debian-based GNU/Linux systems, for example, we recommend that you install the following development packages:
-
libfontconfig1-dev
-
libfreetype6-dev
-
libx11-dev
-
libx11-xcb-dev
-
libxext-dev
-
libxfixes-dev
-
libxi-dev
-
libxrender-dev
-
libxcb1-dev
-
libxcb-glx0-dev
-
libxcb-keysyms1-dev
-
libxcb-image0-dev
-
libxcb-shm0-dev
-
libxcb-icccm4-dev
-
libxcb-sync-dev
-
libxcb-xfixes0-dev
-
libxcb-shape0-dev
-
libxcb-randr0-dev
-
libxcb-render-util0-dev
-
libxcb-util-dev
-
libxcb-xinerama0-dev
-
libxcb-xkb-dev
-
libxkbcommon-dev
-
libxkbcommon-x11-dev
Some of these packages depend on others in this list, so installing one may cause others to be automatically installed. Other distributions may provide system packages with similar names.
Accessibility Dependencies▲
The Qt accessibility implementation uses the Assistive Technology Service Provider Interface (AT-SPI). Besides DBUS, the development package libatspi2.0-dev must be installed.
OpenGL Dependencies▲
Configure attempts to automatically detect OpenGL ES 2.0, or later, or regular desktop OpenGL. You can disable OpenGL support by using the -no-opengl option.
The Qt OpenGL module (which contains classes that start with QGL) has been deprecated in favor of the Qt GUI module (which contains classes that start with QOpenGL).
QDoc Dependencies▲
QDoc uses Clang to parse C++ code. If you wish to build QDoc manually, refer to Installing Clang for QDoc for specific build requirements.
