Hello loh.tar,
it seems the you are using the Build Plugin. I have the following issues, maybe you have a solution.
**Build with errors**
I use this build command to build kate:
```
cd ~/kde/build/frameworks/ktexteditor/ && ninja install && cd ~/kde/build/kde/applications/kate/ && ninja install
```
After build the Output slider always changes to "Parsed output" which contains nothing even if there are compiler errors or warnings. Is this normal? (Apparently not, see comments, TODO: file bug report)
**Run**
To run Kate I press F4 to activate the Terminal and then I use the history to invoke
```
bash -c "cd /home/gregor/kde/build/kde/applications/kate ; source prefix.sh ; ./kate/kate --startanon"
```
How do you do it? Ideally, I would like to have one single shortcut for this action (an idea for this documented here: https://phabricator.kde.org/T10324).
