configure -opengl es2 -no -angle Dynamically Loading Graphics Drivers 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. ANGLE requires that the DirectX SDK is installed when building Qt.
ANGLE implements the OpenGL ES 2.0 API on top of 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: configure -icu Graphics Driversįor Qt Quick 2 to work, a graphics driver that provides OpenGL 2.1 or higher is required.
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, as long as Qt WebKit is not used. Qt Core can be configured to either rely on ICU functionality, or fall back to Windows API and internal algorithms with somewhat reduced functionality.įrom Qt 5.3 and onwards, configure does not link Qt Core against ICU libraries anymore by default. Qt WebKit, and applications using it, always need the ICU libraries. 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. Note: When building for 64-bit environments, de-activate the WarnAsError option in every project file, otherwise, integer conversion warnings will break the build. Building the library requires the installation of the Direct X SDK.

ANGLE: This library converts OpenGL ES 2.0 API calls to DirectX 9, 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.These are not mandatory, but some components (for example, Qt WebKit) may depend on them. The following libraries may be used when running Qt 5 applications in Windows. This page describes the required libraries and environment for Qt for Windows.
