QCreator: how to create debug build configuration

Question

I started a new C++/Qt-Desktop project in QCreator and two build configurations were automatically created:

• a Release-Configuration where the build was created in a separate directory than the source-code
• a Debug-Configuration, where additional compiler flags were set and you could nicely debug with Valgrind

Somehow I got these build-configurations deleted (either by moving to a new computer, or opening the project on another computer - I don't know).

How to I recreate these two (apprently default) configurations for my specific project?

Answer 1

1. close your project

Answer 2

1. Open your project.

2. Go to the Projects pane.

3. Select the Build & Run tab.

4. Select the Build subtab.

5. In the "Edit build configuration:" line, click Add dropdown, select Build submenu.

6. Select the Debug or Release configuration in Build Steps->Details.
