man qtchooser (1): a wrapper used to select between Qt development binary versions

SYNOPSIS

qtchooser -list-versions
qtchooser -print-env [-qt=version]
qtchooser -run-tool=tool [-qt=version] [program_arguments]
<executable_name> [-qt=version] [program_arguments]

DESCRIPTION

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.

OPTIONS

The options which apply to the qtchooser command are:

-list-versions

: Lists available Qt versions from the configuration files

-print-env

: Prints environment information

-qt=version

: Selects version as the Qt version to be used

-run-tool=tool

: Runs the selected tool.

ENVIRONMENT

QTCHOOSER_NO_GLOBAL_DIR: If qtchooser has been built with QTCHOOSER_GLOBAL_DIR (predefined search paths for qtchooser's configuration files, useful in some distros), setting this variable will override its effect.
QT_SELECT: Same as -qt=version. If set, the selected configuration is used and binaries symlinked to qtchooser will be executed without additional parameters.
XDG_CONFIG_HOME
XDG_CONFIG_DIRS: Used as specified in <http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html>

FILES

/etc/xdg/qtchooser/*.conf: 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.
$HOME/.config/qtchooser/*.conf: User configuration files.
