For example, \l{glossary-device}{device} manufacturers provide special Qt versions for developing applications for their devices. \section1 Registering Installed Qt Versions \QC automatically detects the Qt versions that are registered by your system or by installers. To view detailed information for each Qt version, select it in the list and select \uicontrol Details in the \uicontrol {Qt version for} section. \image qtcreator-qt-versions.png "Qt Versions tab in Kit options" To remove invalid Qt versions, select \uicontrol {Clean Up}. You can link to a Qt that you installed using the Qt Maintenance Tool to automatically register the installed Qt versions. The mechanism does not handle Qt versions installed by the system using some other package manager, such as your Linux distribution, brew on \macos, or Chocolatey on Windows, nor a self-built Qt. To link to a Qt installation: \list 1 \li Select \uicontrol Tools > \uicontrol Options > \uicontrol Kits > \uicontrol {Qt Versions} > \uicontrol {Link with Qt}. \image qtcreator-link-with-qt.png "Choose Qt Installation dialog" \li In the \uicontrol {Qt installation path} field, enter the path to the directory where you installed Qt. \li Select \uicontrol {Link with Qt} to automatically register Qt versions and kits in the Qt installation directory. \li Select \uicontrol {Restart Now} to restart \QC. \endlist To remove the automatically detected Qt versions from the list, select \uicontrol {Link with Qt} > \uicontrol {Remove Link}. If a Qt version is still not listed under \uicontrol Auto-detected, select \uicontrol {Add} to add it manually. You specify the Qt version to use for each \l{glossary-buildandrun-kit} {kit} for building and running your projects in \uicontrol Tools > \uicontrol Options > \uicontrol Kits. \section1 Setting Up New Qt Versions To add a Qt version: \list 1 \li Select \uicontrol Tools > \uicontrol Options > \uicontrol Kits > \uicontrol {Qt Versions} > \uicontrol Add. \li Select the qmake executable for the Qt version that you want to add. \li Select the Qt version to view and edit it. \li In the \uicontrol{Version name} field, edit the name that \QC suggests for the Qt version. \li In the \uicontrol{qmake location} field, you can change the qmake location. \li If the Qt version is for QNX, enter the path to your installed QNX SDK in the \uicontrol{QNX SDK} field. \endlist To remove a Qt version that you added manually, select it in the \uicontrol Manual list and then select \uicontrol Remove. \section1 Registering Documentation By default, \QC registers only the latest available version of the documentation for each installed Qt module. To register the documentation sets of all installed Qt versions, choose \uicontrol{All} from the \uicontrol{Register documentation} list. To register no Qt documentation at all, choose \uicontrol{None}. The default behavior is \uicontrol{Highest Version Only}. \section1 Troubleshooting Qt Installations If \QC detects problems in the installation of a Qt version, it displays warnings and errors beside the name of the Qt version in the list. Select the Qt version to see more information about the issue and suggestions for fixing it. To determine whether a particular Qt version is installed correctly, \QC calls \c {qmake -query} and checks that the directories referenced in the output exist. When \QC complains about the installation of a self-built Qt version, try running \c {make install} in the build directory to actually install Qt into the configured location. If you installed Qt using the Qt installer, run the Qt maintenance tool to check for updates or to reinstall the Qt version. \section1 Minimum Requirements If your build of Qt is incomplete but you still want to use QMake as build system, you need to ensure the following minimum requirements to be able to use that setup with \QC. \list 1 \li qmake is an executable that understands the \c -query command line argument. \li The \c bin and \c include directories have to exist. \QC fetches these directories by running \c{qmake -query}. \li The \c mkspecs directory should be complete enough to parse .pro files. \endlist If your Qt version has no \c libQtCore.so, \QC is unable to detect the ABI. */
