Adding Kits

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 Remote Linux Device
• iOS Device
• iOS Simulator
• MCU Device (commercial only)
• QNX Device
• WebAssembly Runtime
• Windows Phone
• Windows Phone Emulator
• Windows Runtime (local)

Filtering Kit Settings

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 工具 > 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 .

Specifying Kit Settings

To add kits:

1. 选择 工具 > Options > Kits > Add .

   

   To clone the selected kit, select Clone .

2. 在 Name column, enter a name for the kit.
3. Select the button to select an image to use as an icon for the kit.
4. 在 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.
5. 在 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.

6. 在 Device field, select a device.
7. 在 Sysroot field, specify the directory where the device image is located. If you are not cross-compiling, leave this field empty.
8. 在 Emulator skin field, select the skin to use for the Boot2Qt Emulator Device .
9. 在 编译器 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 添加编译器 . 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.
10. 在 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 .
11. 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.
12. 在 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.

13. 在 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 PATH environment 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.

14. 在 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.
15. 在 Additional Qbs profile settings field, select Change to add settings to Qbs build profiles. For more information, see Editing Qbs Profiles .
16. 在 CMake Tool field, select the CMake executable to use for building the project. Select Manage to add installed CMake executables to the list. For more information, see Adding CMake Tools .
17. 在 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.
18. 在 CMake configuration field, select Change to edit the parameters of the CMake configuration for the kit.
19. 在 Meson tool field, select the Meson tool to use for building the project. Select Manage to add installed Meson tools to the list. For more information, see Adding Meson Tools .
20. 在 Ninja tool field, select the Ninja tool to use for building the project with Meson. Select Manage to add installed Ninja tools to the list.

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 .

Using Ninja as a CMake Generator

要使用 Ninja with CMake, you must install it and select it as the CMake generator in the build and run kit:

1. Install Ninja.
2. Add the path to the Ninja executable to the value of the PATH system variable.
3. 选择 工具 > Options > Kits , and then select the build and run kit for the project.
4. 选择 Change next to the CMake generator field to open the CMake Generator 对话框。

   

5. 在 生成器 field, select Ninja .
6. 选择 OK to return to the Kits tab.
7. 选择 OK or Apply to save your changes.

注意： To make sure that old build artifacts don't get in the way the first time you build the project after the change, select 构建 > Rebuild Project . This cleans up the build directory and performs a new build.

Editing Qbs Profiles

To view the Qbs profile associated with the kit, select 工具 > Options > Qbs > Profiles .

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:

1. 选择 Change next to the Additional Qbs Profile Settings field to open the Custom Properties 对话框。

   

2. Double-click an empty cell in the Key column to specify the key to add or modify as: <module_name>.<property_name> .
3. Double-click the cell on the same row in the Value column to specify a value as a JSON literal.
4. 选择 Add to add the key-value pair.
5. Click OK .

To modify an existing value, double-click it in the Value field.

To remove the selected property, select 移除 .
