Get and Install Qt with Command Line Interface

Use the command line interface with Qt Online Installer and Qt Maintenance Tool to install, uninstall, update, and search components.

The command line interface supports both interactive and non-interactive usage (unattended usage). The following topics provide examples and information on how you can use the command line interface:

Component Names for Installation

Quick Installation with Alias Packages

Note: Quick installation with alias packages will be available in Qt Online Installer release 4.8.

Instead of searching for specific package names for installation, you can use alias packages to install the most common configurations. Alias packages are a shortcut to include the actual packages for an easier installation experience.

To list the existing alias packages, use the following command on the command line interface:

 installer.exe / maintenancetool.exe search

The contents of the alias packages are listed in the table below.

Note: Qt 6.7.0 release is used in the alias package examples listed below. Always remember to use the packages that match the Qt release you are working on.

Listing Non-Alias Packages

To list the non-alias packages, use the following command on the command line interface:

 installer.exe / maintenancetool.exe search --type package

Advanced Searching for Specific Installation Packages

Search available packages with the search command and regular expressions: search <regexp>. You can filter the results with --filter-packages <regexp>. For example, filtering with the display name information can help search.

For example, the following command finds all MSVC 2019 packages for Qt 6.7.0:

 search .*670.*msvc2019

You get the same result when you filter the search result as follows:

 search --filter-packages DisplayName=MSVC 2019,Version=6.7.0

As a result, you get the following packages:

 <availablepackages>
     <package name="qt.qt6.670.win64_msvc2019_64" displayname="MSVC 2019 64-bit" version="6.7.0-0-202303290841"/>
     <package name="qt.qt6.670.win64_msvc2019_arm64" displayname="MSVC 2019 ARM64 (TP)" version="6.7.0-0-202303290841"/>
 </availablepackages>

You can also use filtering when you search all Qt versions that some package is provided for. For example, search all Qt Charts packages provided for Qt versions:

 search --filter-packages DisplayName=charts

The search result is as follows:

 <availablepackages>
     <package name="qt.qt5.5125.qtcharts" displayname="Qt Charts" version="5.12.5-0-201909090651"/>
     <package name="qt.qt6.641.addons.qtcharts" displayname="Qt Charts" version="6.4.1-0-202211101525"/>
     <package name="qt.qt5.5123.qtcharts" displayname="Qt Charts" version="5.12.3-0-201904161619"/>

Installing Without User Interaction

By default, Qt Online Installer or Qt Maintenance Tool may ask for additional information during installation, which requires user attention. Unattended usage via the command line interface is possible by providing all the requested information beforehand with appropriate options.

New Installation with Qt Online Installer

You can do new installations from the command line interface without user interaction as follows:

  1. Define the Qt Online Installer executable.
  2. Define the installation directory with --root.
  3. Use the install <list of packages> command with options for unattended usage. See the full list of options in Options for Unattended Usage.

The following examples demonstrate how you install Qt 6.7.0 binaries with Qt Online Installer for Windows, macOS, and Linux. The unattended commands automatically accept the licenses (--accept-licenses), answer all message queries with their default answer (--default-answer), and skip asking for permission to continue performing (--confirm-command):

 # Windows: new installation with Qt Online Installer
 qt-unified-windows-x64-[Qt Online Installer version]-online.exe --root C:\Users\[username]\installation_dir --accept-licenses --default-answer --confirm-command install qt.qt6.670.win64_msvc2019_64

 # macOS: new installation with Qt Online Installer
 qt-unified-macOS-x64-[Qt Online Installer version]-online.dmg --root /home/<username>/installation_dir --accept-licenses --default-answer --confirm-command install qt.qt6.670.clang_644

 # linux: new installation with Qt Online Installer
 qt-unified-linux-x64-[Qt Online Installer version]-online.run --root /home/<username>/installation_dir --accept-licenses --default-answer --confirm-command install qt.qt6.670.gcc_64

Options for Unattended Usage lists all available options for unattended usage.

Updating Installation with Qt Maintenance Tool

You can update existing installation from the command line interface without user interaction as follows:

  1. Define the Qt Maintenance Tool executable.
  2. Use install <list of packages> with options for unattended usage. See the full list of options in Options for Unattended Usage.

The following examples demonstrate how you add Qt 6.7.0 binaries with Qt Maintenance Tool to an exsting installation on Windows, macOS, and Linux. The unattended commands automatically accept the licenses (--accept-licenses), answer all message queries with their default answer (--default-answer), and skip asking for permission to continue performing (--confirm-command):

 # Windows: update installation with Qt Maintenance Tool
 MaintenanceTool.exe --accept-licenses --default-answer --confirm-command install qt.qt6.670.win64_msvc2019_64

 # macOS: update installation with Qt Maintenance Tool
 MaintenanceTool.app/Contents/MacOS/MaintenanceTool --accept-licenses --default-answer --confirm-command install qt.qt6.670.clang_64

 # linux: update installation with Qt Maintenance Tool
 MaintenanceTool.run --accept-licenses --default-answer --confirm-command install qt.qt6.670.gcc_64

Options for Unattended Usage

The following table lists all options for unattended command line usage:

Option for unattended usageDescription
--accept-licensesAutomatically accepts all license agreements.
--accept-obligationsIn the opensource installations, accepts Qt Open Source usage obligations without user input.
--default-answerAnswers all message queries with their default answer.
--auto-answer <identifier=value>In case you want different answers to certain queries, you can use this option. For example, --auto-answer telemetry-question=Yes,AssociateCommonFiletypes=Yes. See all message identifiers in Message Identifiers for --auto-answer.
--accept-messagesAccepts all message queries.
--reject-messagesRejects all message queries.
--confirm-commandBy default, Qt Online Installer and Qt Maintenance Tool print a summary of components to be affected by the option. Then they ask for permission to continue acting, to prevent accidental changes. This option skips asking for permission to continue.
--email <your_email>Provides the email when you log in from the command line. For more information, see Providing Login Information.
--pw <your_pw>Provides the password when you log in from the command line. For more information, see Providing Login Information.
--file-query <identifier=value>Sometimes Qt Online Installer asks for a file or a folder location. You can provide the location with --file-query <identifier=value>. For example, --file-query PathForSDP7=<path_to_sdp>.

The identifiers are printed into the command line before the actual question and message type. You can pick up the identifiers from there.

Message Identifiers for --auto-answer

Use the --auto-answer option to provide answers to certain queries. The following table lists known identifiers and values used for --auto-answer:

IDValuesDefault
OperationDoesNotExistErrorAbort, IgnoreIgnore
OverwriteTargetDirectoryYes, NoNo
stopProcessesForUpdatesRetry, Ignore, CancelCancel
installationErrorWithCancelRetry, Ignore, CancelCancel
installationErrorWithIgnoreRetry, IgnoreIgnore
AssociateCommonFiletypesYes, NoYes
telemetry-questionYes, NoYes

Providing Login Information

Qt Online Installer and Qt Maintenance Tool have a forced login. The forced login uses information on the qtaccount.ini file if it is available in cache. You find qtaccount.ini as follows:

Hostqtaccount.ini location
WindowsC:\Users\<username>\AppData\Roaming\Qt
macOS/Users/<username>/Library/Application Support/Qt/qtaccount.ini
Linux/home/<username>/.local/share/Qt/qtaccount.ini

Optionally, you can login either from the command line using the switches for email and password: --email <your_email> and --pw <your_pw>.

Alternatively, you can save the jwt token to the environment variable QT_INSTALLER_JWT_TOKEN. You find the token in the qtaccount.ini file.

Installing With User Interaction

You can use the command line interface with user interaction as follows:

  1. Define the executable:
    • Qt Online Installer if you need to do a new installation.
    • Qt Maintenance Tool if you need to update an existing installation.
  2. When you do a new installation, define the installation directory with --root
  3. Use install <list of packages> to install the listed packages.

The following examples demonstrate how you create a new installation of Qt 6.7.0 binaries with Qt Online Installer for Windows, macOS, and Linux:

 # Windows: new installation with user interaction
 qt-unified-windows-x64-[Qt Online Installer version]-online.exe --root C:\Users\[username]\installation_dir install qt.qt6.670.win64_msvc2019_64

 # macOS: new installation with user interaction
 qt-unified-macOS-x64-[Qt Online Installer version]-online.dmg --root /home/<username>/installation_dir install qt.qt6.670.clang_64

 # linux: new installation with user interaction
 qt-unified-linux-x64-[Qt Online Installer version]-online.run --root /home/<username>/installation_dir install qt.qt6.670.gcc_64

The following examples demonstrate how you update your existing installation by installing the Qt 6.7.0 binaries with Qt Maintenance Tool:

 # Windows: update installation with Qt Maintenance Tool
 MaintenanceTool.exe install qt.qt6.670.win64_msvc2019_64

 # macOS: update installation with Qt Maintenance Tool
 MaintenanceTool.dmg install qt.qt6.670.clang_64

 # Linux: update installation with Qt Maintenance Tool
 MaintenanceTool.run install qt.qt6.670.gcc_64

Uninstalling Packages

The command line interface provides two commands for uninstalling packages:

  • The remove <list of packages> command uninstalls the listed packages.
  • The purge command uninstalls all installed packages.

You should use both commands with Qt Maintenance Tool.

By default, Qt Maintenance Tool prints a summary of components to be affected by the command. Then the tool asks for permission to continue acting, to prevent accidental changes. Use --confirm-command to skip asking for permission to continue.

The following example uninstalls the Qt 6.7.0 binaries without user interaction:

 # windows
 MaintenanceTool.exe --confirm-command remove qt.qt6.670.win64_msvc2019_64

 # macOS
 MaintenanceTool.dmg --confirm-command remove install qt.qt6.670.clang_64

 # linux
 MaintenanceTool.run --confirm-command remove qt.qt6.670.gcc_64

The following examples uninstall all packages and ask for permission to continue performing the action:

 # Windows
 MaintenanceTool.exe purge

 # macOS
 MaintenanceTool.dmg purge

 # Linux
 MaintenanceTool.run purge

Listing Installed Packages

The list command lists all packages you have installed. Use the command with Qt Maintenance Tool as follows:

 # Windows
 MaintenanceTool.exe list

 # macOS
 MaintenanceTool.dmg list

 # Linux
 MaintenanceTool.run list

Checking Updates

The check-updates command checks the updates that are available for the installed packages. Use the command with Qt Maintenance Tool as follows:

 # Windows
 MaintenanceTool.exe check-updates

 # macOS
 MaintenanceTool.dmg check-updates

 # Linux
 MaintenanceTool.run check-updates

Updating Packages

The update command updates the installed packages. Use the command with Qt Maintenance Tool as follows:

 # windows
 MaintenanceTool.exe update

 # macOS
 MaintenanceTool.dmg update

 # linux
 MaintenanceTool.run update

Use the command <installer_executable> --help to study the available commands and options. Popular commands are as follows:

CommandUsage

Qt Installer Framework Manual provides more information about the commands and options.

Selecting Mirror for Opensource

Qt Online Installer has an option for selecting a mirror for opensource metadata and downloads. Set the mirror from the command line with the --mirror option.

For example, use --mirror as follows:

 installer(.exe) --mirror http://www.nic.funet.fi/pub/mirrors/download.qt-project.org
 installer(.exe) --mirror http://ftp2.nluug.nl/languages/qt
 maintenancetool(.exe) --mirror http://qt.mirror.constant.com

As the example shows, don't use the full path but use the path before '/online' (no forward slash at the end).

You find the available mirrors from https://download.qt.io/online/qtsdkrepository/windows_x86/root/qt/Updates.xml.mirrorlist.
