Since it’s possible to disable OpenGL related plugins, it would be nice to be able to get rid of all the OpenGL dependencies if Qt Creator needs to run e.g on a virtual machine without OpenGL support.
You normally install libraries from a package manager in Linux. That Qt -no-opengl thing is a build option, and usually only made use of in Windows, which has poor OpenGL support by default. On Linux OpenGL is usually always available if there’s a graphics system installed.
By default, Qt is configured to use ANGLE, which is bundled with Qt and depends on the DirectX SDK. ANGLE enables running Qt applications that depend on OpenGL , without installing the latest OpenGL libraries. The – opengl option can be used to configure Qt to use the OpenGL in the target system, a different version of OpenGL ES (with or without …
OpenGL is required by QtGui and QtQuick modules: you can’t compile them without it. You can skip unneeded modules with @-skip modulename @, ANGLE enables running Qt applications that depend on OpenGL , without installing the latest OpenGL drivers. If ANGLE also fails, Qt will fall back to software rendering, which is the slowest but most safe of the rendering methods. The – opengl option can be used to configure Qt to use the OpenGL in the target system, a different version of OpenGL …
The following feature keywords are relevant for choosing the OpenGL implementation: disable_desktopgl – Disables OpenGL. This ensures that Qt does not attempt to use regular OpenGL (opengl32.dll), and that it starts with ANGLE right away. This is useful to prevent bad OpenGL drivers from crashing the application. disable_angle – Disables ANGLE. Ensures that Qt does not attempt to use ANGLE (and.
configure Options. The authorative source of the available configure options (and defaults) is the script itself. Here is the output of configure -help as it was when the documentation was built.. Note that some configure options will change the default value of other options.
OpenGL ES 2.0 (Open Graphics Library for Embedded Systems) is a stripped-down version of OpenGL for use on embedded systems, which is missing some functions. The Qt Quick 2 stack in Qt 5 is based on OpenGL , and requires OpenGL 3.0 (alternatively OpenGL 2.x with the framebuffer_object extension) or higher or OpenGL ES 2.0.
DEFINES + = QT _ DISABLE _DEPRECATED_BEFORE = 0x050F00. In CMake, you can use add_compile_definitions: add_compile_definitions … It is still possible to use OpenGL calls in Qt applications, but the OpenGL APIs are moved to the Qt OpenGL module. The graphical backend for Qt Widgets applications are unchanged from Qt 5.
This page describes the required libraries and environment for Qt for Windows.. Graphics Drivers. For Qt Quick to work, a graphics driver that provides Direct 3D 11.1, Vulkan 1.0, or OpenGL 2.1 or higher is required. As of Qt 6, the default for Qt Quick on Windows is Direct3D 11.
