Can't find C++ debugger

ebonnett

Last night I was working in Qt Creator (4.6.1) and it crashed. Windows 10 gave me the "Qt Creator has stopped working" popup. I restarted Qt Creator and my project file had been corrupted (I assume this because my toolkits for windows were gone). I deleted my pro.user file and let Qt recreate it. Since then when I try to debug Android, the app dies with "Can't find C++ ![alt text](image url)debugger.

My setup:
Qt Creator 4.6.1
NDK r10e
SDK 26.1.1
JDK 1.8.0_131

Here is a screenshot of the Auto-detected debuggers

Here are some things I have tried:

Cloning the toolkit and changing the debugger
Uninstalling Qt Creator and reinstalling 4.6.1.
Installing the Qt Creator 4.7.0 Beta.

Nothing is working. Does anyone have any insight into why or what a workaround is? I'm really pressed for time (as I'm sure everyone is) but I have to release in a matter of days and have pressing issues to resolve.

Thank you in advance for any expert tutelage given.

Hi,

Did you also try to delete Qt Creator's configuration ?

No, I have not. Where might I find that?

(iirc) c:\users\ <user>\AppData\Roaming\QtProject

but I cannot check right now :(

Debugging with 4.6.1 does not seem to work, see also: https://bugreports.qt.io/browse/QTCREATORBUG-20403

Really? So there's no answer to this question? Seems like Qt is unusable. Am I the ONLY person in the entire community that has a fully developed, almost ready to release app but can no longer debug android? Seriously. I have uninstalled Qt Creator and the framework many times. I've removed the NDK, SDK, Windows SDK, damn near everything I can think of. I've installed fresh and this thing STILL can't find the debugger? This is bad. Really bad. I can't resolve the problems I'm experiencing if I can't debug. I'm starting to think it was a really bad idea to use Qt. Meanwhile, I'm completely screwed. Very frustrating.

I figured this particular problem out. I went into Android Studio and played around. Ultimately it told me that it too couldn't find the C++ debugger and asked me if I wanted to intall it. I did and that solved that problem. Now I need to fix the issue where it won't connect to the port. Still can't debug on my S9 or Nexus 6P.
