To use an OpenGL ES 2.0 emulator instead of ANGLE, use the configure options: -opengl es2 -no-angle. To use OpenGL, pass the command line options -opengl desktop to the configure script. If you installed additional OpenGL drivers from your hardware vendor, then you may want to consider using this version of OpenGL instead of ANGLE. To use a custom version of ANGLE, set the ANGLE_DIR environment variable to point to the ANGLE source tree before building Qt. Possible values are d3d11, d3d9 and warp. For these cases, the environment variable QT_ANGLE_PLATFORM (introduced in Qt 5.4) can be used to control the render backend. However, some graphics cards may not fully support it. ANGLE requires that the DirectX SDK is installed when building Qt.ĪNGLE chooses the render backend depending on availability. ANGLE implements the OpenGL ES 2.0 API on top of DirectX 11 or DirectX 9.

Qt includes a version of the ANGLE project which is included from the Windows Qt installers. The default driver from Windows is OpenGL 1.1. To explicitly enable the use of ICU in Qt Core, pass -icu to configure:įor Qt Quick 2 to work, a graphics driver that provides OpenGL 2.1 or higher is required. QCollator::setNumericMode() does work consistently on all Windows versions.QLocale::toUpper(), QLocale::toLower() always use case conversion rules specific to the locale.Extended set of text codecs (see QTextCodec).Behavior matches other platforms more closely.Letting Qt Core utilize the ICU libraries however has following advantages: This reduces the size of a self-contained application package considerably. ICUįrom Qt 5.3 and onwards, configure does not link Qt Core against ICU libraries anymore by default.

See Secure Sockets Layer (SSL) Classes for instructions on building Qt with SSL support. Support for Secure Sockets Layer (SSL) communication is provided by the OpenSSL Toolkit, which must be obtained separately. ANGLE: This library converts OpenGL ES 2.0 API calls to DirectX 11 or DirectX 9 calls (depending on availability), removing the need to install graphics drivers on the target machines.At run-time, the ICU DLLs need to be found by copying the DLLs to the application folder or by adding the bin folder of the ICU installation to the PATH environment variable. ICU: Qt 5 can make use of the ICU library for enhanced UNICODE and Globalization support (see QTextCodec, QCollator::setNumericMode()).Īt compile time, the include and lib folders of the ICU installation must be appended to the INCLUDE and LIB environment variables.The following third-party libraries may be used when running Qt 5 applications on Windows. This page describes the required libraries and environment for Qt for Windows.
