Since version 5.11, QDoc uses Clang to parse C++ code. Qt WebEngine has additional build requirements which are listed in the Qt WebEngine Platform Notes. The following development packages should be installed: Qt Speech depends on Speech Dispatcher (libspeechd) on the Linux platform. The package names for GStreamer vary between Linux distributions try searching for gstreamer or libgstreamer in your distribution's package repository to find suitable packages. These additional plugins contain various codecs for audio and video decoding, as well as the necessary components for using the camera APIs. To run applications that use Qt Multimedia, you might also need to install the following GStreamer plugins: 'good', 'ugly', 'bad', ffmpeg (0.10), and libav (1.x). To build Qt Multimedia, you need the GStreamer library, base plugins, and development files for your system. The minimum required version of GStreamer is 0.10.24. Multimedia DependenciesĪs described in the Multimedia overview, Qt Multimedia uses the GStreamer multimedia framework as the backend for audio and video playback on Linux. Note: 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). You can disable OpenGL support by using the -no-opengl option. OpenGL DependenciesĬonfigure attempts to automatically detect OpenGL ES 2.0, or later, or regular desktop OpenGL. Besides DBUS, the development package libatspi2.0-dev must be installed. The Qt accessibility implementation uses the Assistive Technology Service Provider Interface (AT-SPI). Other distributions may provide system packages with similar names. Some of these packages depend on others in this list, so installing one may cause others to be automatically installed. On Debian-based GNU/Linux systems, for example, we recommend that you install the following development packages: Utility library for XCB for XImage and XShmImage, used for QBackingStore and cursor supportÄevelopment packages for these libraries contain header files that are used when building Qt from its source code. Utility library for XCB for keycode conversion X C Bindings for Resize and Rotate Extension Utility library for XCB for Render extension X Rendering Extension used for anti-aliasing and alpha cursor support
