The run settings to specify depend on the type of the project and on the kit that you build and run the project with.
Qt Creator automatically creates run configurations for your project. To view and modify them, select Projects > Build & Run > 运行 .
To prevent Qt Creator from automatically creating run configurations, select 工具 > Options > Build & Run , and then deselect the Create suitable run configurations automatically check box.
The available run configurations are listed in the Run configuration field. To add run configurations for a project, select Add . To add a run configuration that is based on the current one, select Clone .
To rename the current run configuration, select Rename .
To remove the current run configuration, select 移除 .
The run configurations for qmake projects derive their executable from the parsed .pro files. For more information on how the commands are constructed, see Starting External Processes .
Qt Creator automatically adds run configurations for all targets specified in the CMake project file,
CMakeLists.txt
.
Qt Creator automatically adds run configurations for all targets declared with
executable()
function in Meson build descriptions.
To prevent Qt Creator from automatically creating run configurations for SUBDIRS projects, specify the following variable in the .pro file of the SUBDIRS project:
CONFIG += qtc_runnable
.
Qt Creator creates run configurations only for subprojects that also have
CONFIG += qtc_runnable
set in their .pro files.
You can specify command line arguments to be passed to the executable and the working directory to use. The working directory defaults to the directory of the build result.
For console applications, check the Run in terminal check box. To specify the terminal to use on Linux and macOS, select 工具 > Options > Environment > 系统 .
To run with special environment variables set up, select them in the Run Environment section. For more information, see Selecting the Run Environment .
When building an application, Qt Creator creates a list of directories where the linker will look for libraries that the application links to. By default, the linked libraries are made visible to the executable that Qt Creator is attempting to run. Usually, you should disable this option only if it causes unwanted side-effects or if you use deployment steps, such as
make install
, and want to make sure that the deployed application will find the libraries also when it is run without Qt Creator.
To disable library linking for the current project, deselect the Add build library search path to PATH check box. To disable library linking for all projects, select 工具 > Options > Build & Run , and then deselect the Add linker library search paths to run environment check box.
The Use debug version of frameworks (DYLD_IMAGE_SUFFIX=_debug) option (only available on macOS) enables you to debug (for example, step into) linked frameworks, such as the Qt framework itself. You do not need this option for debugging your application code.
You can also create custom executable run configurations where you can set the executable to be run. For more information, see Specifying a Custom Executable to Run .
Qt Creator integrates Valgrind code analysis tools for detecting memory leaks and profiling function execution. You can configure the tools according to your needs.
You can specify Valgrind settings either globally for all projects or separately for each project.
To specify Valgrind settings for the current project:
For more information about the settings, see:
Click Restore Global to revert to the global settings.
To specify global Valgrind settings, select Tools > Options > Analyzer .
To select the languages to debug, select the Enable C++ and Enable QML check boxes.
注意： Opening a socket at a well-known port presents a security risk. Anyone on the Internet could connect to the application that you are debugging and execute any JavaScript functions. Therefore, you must make sure that the port is properly protected by a firewall.
For more information about debugging, see 调试 .
To run and debug an application on an Android device, you must create connections from the development host to the device, as instructed in 连接 Android 设备 .
A default set of Android Activity manager (am) start options is applied when starting applications. You can specify additional start options in the Activity manager start options field. However, if the default options conflict with the added options, the application might not start.
The default arguments for the Activity manager for a normal run:
am start -n org.qtproject.example.notification/org.qtproject.qt5.android.bindings.QtActivity
The default arguments for the Activity manager for the debugger mode:
am start -n org.qtproject.example.notification/org.qtproject.qt5.android.bindings.QtActivity -D
For example, to run the application as a particular user, enter the start option
--user 10
, where
10
is the user ID of the user account.
You can specify shell commands to run before the application is started and after it is quit. For example, enter the following commands to unlock the screen and to switch to the user account
10
on the device before running the application:
input keyevent 82 am switch-user 10
Enter the following commands to switch back to the default user,
0
, and to unlock the screen after the application is quit:
am switch-user 0 input keyevent 82
To run and debug an application on a Linux-based device, you must create connections from the development host to the device and add the device configurations to kits . Click Manage Kits to add devices to kits. For more information, see 连接一般远程 Linux 设备 .
When you run the application, Qt Creator copies the files to the connected device.
The run settings display the path to the executable file on the development host and on the device. To specify that another application launches your application, for example, enter the command in the Alternate executable on device field and select the Use this command instead check box.
You can specify arguments to pass to your application in the 命令行自变量 field.
To run and debug an application on a QNX device, you must create connections from the development PC to the device. Click Manage device configurations to create a connection. For more information, see 连接 QNX 设备 .
Specifying run settings for QNX Neutrino devices is very similar to Specifying Run Settings for Linux-Based Devices .
To run and debug an application on a Boot2Qt device (commercial only), you must create connections from the development host to the device and add the device configurations to kits . Select Manage Kits to add devices to kits. For more information, see the Installation Guide 在 Qt for Device Creation 文档编制。
The run settings display the path to the executable file on the development host and on the device.
For more information on the deployment steps, see Deploying Applications to Generic Remote Linux Devices .
Qt Creator automatically selects the environment used for running the application based on the device type. You can edit the environment or select another environment in the Run Environment 章节。
You can edit existing environment variables or add, reset and unset new variables.
When running on the desktop, the 构建环境 is used by default, but you can also use the System Environment without the additions made to the build environment. For more information, see 构建环境 .
To run in a clean system environment, select Clean Environment .
When running on a mobile device connected to the development host, Qt Creator fetches information about the Device Environment from the device. Usually, it does not make sense to edit the device environment.
To modify the environment variable values for the run environment, select Batch Edit 。更多信息，见 Batch Editing .
If you use CMake, Meson or the generic project type in Qt Creator, or want to run a custom desktop executable, create a Custom Executable run configuration for your project. For example, when working on a library, you can run a test application that links against the library.
Specify the executable to run, command line arguments, working directory, and environment variables to use.
You can specify run settings for kits with Desktop device type:
You can specify settings for running Qt for Python applications:
If you want to run some other Python file than
main.py
, create a custom executable run configuration:
