Qt Creator groups settings used for building and running projects as kits to make cross-platform and cross-configuration development easier. Each kit consists of a set of values that define one environment, such as a device, compiler, Qt version, and debugger command to use, and some metadata, such as an icon and a name for the kit. Once you have defined kits, you can select them to build and run projects.
Qt Creator supports development for the desktop and for the following types of devices:
- Android Device
- Bare Metal Device
- Boot2Qt Device (commercial only)
- Boot2Qt Emulator Device (commercial only)
- Generic Linux Device
- iOS Device
- iOS Simulator
- QNX Device
- Windows Phone
- Windows Phone Emulator
- Windows Runtime (local)
Typically, only a subset of the kit settings is relevant for a particular setup. Therefore, Qt Creator plugins register sets of relevant settings that you can view and modify in Tools > Options > Kits >. For example, if you use CMake to build all your projects, you can hide Qbs and qmake settings by default.
To hide and show settings in the Kits tab for the current kit, select Settings Filter. To view and modify the settings displayed when you add a new kit, select Default Settings Filter.
To add kits:
- Select Tools > Options > Kits > Add.
To clone the selected kit, select Clone.
- In the Name column, enter a name for the kit.
- Select the button to select an image to use as an icon for the kit.
- In the File system name field, enter a name for the kit to use as a part of directory names. This value is used for the CurrentKit:FileSystemName variable, which determines the name of the shadow build directory, for example.
- In the Device type field, select the type of the device.
Double-click the icon next to the field to select the image that is displayed in the kit selector for this kit. You can use any image in a supported file format (for example, PNG). The image is scaled to the size 64x64 pixels. For example, using the compiler logo as an icon allows you to easily see, which compiler is used to build the project for the selected kit.
- In the Device field, select a device.
- In the Sysroot field, specify the directory where the device image is located. If you are not cross-compiling, leave this field empty.
- In the Emulator skin field, select the skin to use for the Boot2Qt Emulator Device.
- In the Compiler field, select the C or C++ compiler that you use to build the project. You can add compilers to the list if they are installed on the development PC, but were not detected automatically. For more information, see Adding Compilers. This setting is used to tell the code model which compiler is used. If your project type and build tool support it, Qt Creator also tells the build tool to use this compiler for building the project.
- In the Environment field, select Change to modify environment variable values for build environments in the Edit Environment Changes dialog. For more information about how to add and remove variable values, see Batch Editing.
- Select the Force UTF-8 MSVC compiler output check box to either switch the language of MSVC to English or to keep the language setting and just force UTF-8 output, depending on the MSVC compiler used.
- In the Debugger field, select the debugger to debug the project on the target platform. Qt Creator automatically detects available debuggers and displays a suitable debugger in the field. You can add debuggers to the list. For more information, see Adding Debuggers.
For Android kits, the Android GDB server field will display the path to GDB server executable.
- In the Qt version field, select the Qt version to use for building the project. You can add Qt versions to the list if they are installed on the development PC, but were not detected automatically. For more information, see Adding Qt Versions.
Qt Creator checks the directories listed in the
PATHenvironment variable for the qmake executable. If a qmake executable is found, it is referred to as Qt in PATH and selected as the Qt version to use for the Desktop kit that is created by default.
- In the Qt mkspec field, specify the name of the mkspec configuration that should be used by qmake. If you leave this field empty, the default mkspec of the selected Qt version is used.
- In the Additional Qbs profile settings field, select Change to add settings to Qbs build profiles. For more information, see Editing Qbs Profiles.
- In the CMake Tool field, select the CMake tool to use for building the project. Select Manage to add installed CMake tools to the list. For more information, see Adding CMake Tools.
- In the CMake generator field, select Change to edit the CMake Generator to use for producing project files. Only the generators with names beginning with the string CodeBlocks produce all the necessary data for the Qt Creator code model. Qt Creator displays a warning if you select a generator that is not supported.
- In the CMake configuration field, select Change to edit the variables of the CMake configuration for the kit.
Qt Creator uses the default kit if it does not have enough information to choose the kit to use. To set the selected kit as the default kit, select Make Default.
To use Ninja with CMake, you must install it and select it as the CMake generator in the build and run kit:
- Install Ninja.
- Add the path to the Ninja executable to the value of the PATH system variable.
- Select Tools > Options > Kits, and then select the build and run kit for the project.
- Select Change next to the CMake generator field to open the CMake Generator dialog.
- In the Generator field, select Ninja.
- Select OK to return to the Kits tab.
- Select OK or Apply to save your changes.
Note: To make sure that old build artifacts don't get in the way the first time you build the project after the change, select Build > Rebuild Project. This cleans up the build directory and performs a new build.
To view the Qbs profile associated with the kit, select Tools > Options > Kits > Qbs.
You can add keys and values to the profile or remove them from it, as well as modify existing values. For a list of available keys and values, see List of Modules in the Qbs Manual.
To edit the Qbs profile associated with the kit:
- Select Change next to the Additional Qbs Profile Settings field to open the Custom Properties dialog.
- Double-click an empty cell in the Key column to specify the key to add or modify as:
- Double-click the cell on the same row in the Value column to specify a value as a JSON literal.
- Select Add to add the key-value pair.
- Click OK.
To modify an existing value, double-click it in the Value field.
To remove the selected property, select Remove.
