Qt

Specifying Run Settings

Qt Creator automatically creates run configurations for your project. To view and modify the settings, select Projects > Build & Run > Run.

The settings to specify depend on the type of the project and on the kit that you build and run the project with.

Click Add to add run settings for a project and Remove to remove the current settings.

Specifying Run Settings for qmake Projects

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.

Specifying Run Settings for Desktop Device Types

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. If you need to run with special environment variables set up, you also do it in the run configuration settings.

The Use debug version of frameworks (DYLD_IMAGE_SUFFIX=_debug) option (available on Mac OS, only) 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. If you select this option, a crash might occur when debugging applications on Mac OS X Snow Leopard. For more information, see Application Crashes when Debugging on Mac OS X Snow Leopard.

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.

Specifying Analyzer Settings

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 analyzer settings either globally for all projects or separately for each project.

To specify analyzer settings for the current project:

  1. In the Analyzer Settings section, select Custom.
  2. Specify analyzer settings for the project.

    "Analyzer Settings"

For more information about the settings, see:

Click Restore Global to revert to the global settings.

To specify global analyzer settings, select Tools > Options > Analyzer.

Specifying Debugger Settings

"Debugger Settings"

To select the languages to debug, select the Enable C++ and Enable QML check boxes. The Debug port is the port to communicate with the debugger. You can use any free port in the registered or dynamic port range.

Note: 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.

If you debug more than one application at a time, you might receive an error message stating that the port is already in use. Specify a free port number in Debug port and try again.

For more information about debugging, see Debugging.

Specifying Run Settings for Linux-Based Devices

To run and debug an application on a Linux-based device (embedded Linux, MeeGo Harmattan, or Maemo), 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 Configuring Connections to Maemo Devices, Configuring Connections to Harmattan Devices, and Connecting Embedded Linux Devices.

When you run the application, Qt Creator copies the files to the connected device.

For MeeGo Harmattan and Maemo device types, Qt Creator also generates an installation package in the build directory by default. You can deliver the installation package to users for installation on devices that are of the same type and run the same firmware as the connected device. For more information, see Deploying Applications to Linux-Based Devices.

For generic embedded Linux devices, 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.

"Run settings for Linux-based devices"

You can specify command line arguments to pass to your application in the Arguments field.

Specifying Run Settings for QNX Devices

To run and debug an application on a QNX or BlackBerry device, you must create connections from the development PC to the device. Click Manage device configurations to create a connection. For more information, see Connecting QNX Devices.

"Run settings for QNX devices"

When you run the application on the BlackBerry device, Qt Creator first creates a BAR package using the settings in the Application Descriptor File. The default is to create the BAR package in the build directory. The BAR package is then deployed to the selected device. For more information, see Deploying Applications to QNX Devices.

Specifying run settings for QNX Neutrino devices is very similar to Specifying Run Settings for Linux-Based Devices.

Selecting the Run Environment

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 section.

You can edit existing environment variables or add, reset and unset new variables.

"Run Environment section"

When running on the desktop, the Build Environment is used by default, but you can also use the System Environment without the additions made to the build environment. For more information, see Build Environment.

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.

Specifying a Custom Executable to Run

If you use CMake 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.

"Run settings for custom executables"

Specifying Run Settings for Qt Quick UI Projects

You can specify run settings for kits with Desktop device type:

  • In the Arguments field, you can specify command line arguments to be passed to the executable.
  • In the Main QML file, select the file that Qt QML Viewer will be started with.
