Qt is a cross-platform C++ application framework. Qt’s primary feature is its rich set of widgets that provide standard GUI functionality.

The Qt Chooser provides a wrapper to switch between versions of Qt development binaries when multiple versions like 4 and 5 are installed or local Qt builds are to be used.

It is commonly used via a symlink from an executable_name like qmake.


The options which apply to the qtchooser command are:


Lists available Qt versions from the configuration files


Prints environment information


Selects version as the Qt version to be used


Runs the selected tool.



Same as -qt=version. If set, the selected configuration is used and binaries symlinked to qtchooser will be executed without additional paramenters.


Used as specified in <>



System-wide configuration files. Each has two lines, the first is the path to the binaries and the second is the path to the Qt libraries. If a default.conf is provided, the settings from it will be automatically used in case nothing else is selected.


User configuration files.
