Running programs in KDevelop

Once you have built a program, you will want to run it. To do this, need to configure Launches for your project. A Launch consists of the name of an executable, a set of command line parameters, and an execution environment (such as "run this program in an external terminal", or "run this program in the debugger").

Setting up launches in KDevelop

  • Select Run -> Configure launches from the menubar.
  • Highlight the project you want to add a launch for and click on the /Add button.
  • From the drop down menu shown, select the name of the launch configuration.
  • Enter the name you want to call the launch configuration (you can edit it later by double clicking it ).
  • In the executable tab, choose the project target or the path where you want to run the program.

Any required command line arguments can be specified in the Arguments: edit box.

If you need to build the executable or add libraries before running it,add the dependencies tab at the bottom of the page,

  • select Build from the dropdown Action: menu.
  • Select the symbol to the right of the textbox and select whatever target you want to have built.
  • Click Ok.

To configure a debug launch:

  • Select on the Debug symbol under the selected launch configuration on the left tab.
  • add the path to the debugger program.

if this is the system's default debugger (e.g. gdb on Linux), then you don't need to do this step.

To run the program:

  • From the menu bar, select Run -> Execute Launchor use the shortcut Shift + F9.

Your program should now run in an external terminal window of KDevelop. The picture above shows the result: The new Run tool subwindow at the bottom shows the output of the program that is being run, in this case the nano text editing program.


If you have configured multiple launches, you can choose which one should run when you hit Shift + F9 by going to Run -> Current Launch Configuration. There is a non-obvious way to edit the name of a configuration, however: in the dialog box you get when you select Run -> Current Launch Configuration, double-click on the name of the configuration in the tree view on the left, which will allow you to edit the configuration's name.

Some useful keyboard shortcuts

Running a program
F8 Build (call make)
Shift + F9 Run
F9 Run program in the debugger; you may want to set breakpoints beforehand, for example by right-clicking with the mouse on a particular line in the source code
