Unable to create a debugging engine in Qt Creator

Question

I have recently installed Qt Creator 4.8.0 based on Qt 5.12.0 and I have it configured like in the image below. However, I haven't managed to start the debugger. As it can be seen, the debugger is correctly set for this kit, the one I'm using right now.

Any solution?

Thanks!

Answer 1

Same error here, in my case GDB was not installed in my docker container where the qt-creator is executed.

Answer 2

In my case, I had to completely trash all of Qt Creator's settings in C:\Users\<my username>\AppData\Roaming\QtProject in order to get debugging working again.

Answer 3

I had the same issue when Qt Creator didn't recognized the path to the Debugger. Due to some reason it showed multiple Auto-detected Debuggers at the same location. And on the top one of the list with the red error indicator.

see

Projects->Manage Kits...->Debuggers

I removed the erroneous Debugger and restart the Qt Creator.

Answer 4

In my case it was needed to select "Enable C++" under Debugger settings screenshot

Answer 5

I had the same error in MacOS, debugger suddenly stopped working (LLDB debugger worked in XCode but not Qt Creator).

In this case, I reinstalled Qt Creator and reinitialized the config by removing the .config/QtProject directory located in homedir. This solved the problem.

Answer 6

The same dumm error QT creator shows when you simply don't have gdb installed. Worked in my case ;)

Answer 7

I got the same error, but in my case I was using the MSVC compiler and the kit didn't manage to find the CDB debugger. I was able to fix it by going to "Add or remove programs" -> "Windows Software Development Kit" -> Modify -> Change -> Debugging Tools for Windows.

Answer 8

Wow! I found it!!! Here in the tab "projects", there are several build and run configurations. Despite you select a default kit, the final one being executed is the one in black under this tab.

Finally I disabled all of them except the one that was properly configured in the Kits window and it worked. I hope this information is helpful for someone. I don't think that part of the configuration is clear.
