Hello guys

Recently I have changed from kate to kdevelop but I have a problem with with this virtual environment. There is always automatically a "!" sign in my terminal, when I want to execute my code and it doesn't go away. Does anyone know how to fix this?
Kind regards!

Posting a screenshot/screencast of the problem would be helpful, as well as details such as what versions of kdevelop and kde libraries you are using on what distro (much of the information can be found in Help > About)
