Unable to debug Android App (Windows + Qt Creator 12 + LLDB)

also getting lots of these on dialog-creations.. what the heck is going on here....
wrote on 20 Feb 2024, 11:41 last edited by CodesInChaossMy app works fine as long as I keep neglecting and going past all these SIGFaults and Sig33s
what's that?
I really wouldn't like to neglect segmentation faults my code or not.
Why am I seeing these now? With QT Creator 12 and not 10?
Looking forward to some guidance.

Now, how a regular developer is even to notice?

Yet again, if I ignore these the app runs FINE.
ideas?
It's like tapping on an UI element is almost guaranteed to result in such a SigFault.

The moment one pastes anything to
QT Creator crashed, Lo and Behold
On my way to reconfigure everything anew.
this feels like an early Alpha of some wanna-be development framework not something that has been around for many many years.
Something I paid for.

wrote on 20 Feb 2024, 12:19 last edited by CodesInChaossyeah sure but for the fact I've wiped out everything QT related.
- QT has been wiped CLEAN the entire QT folder
- everything in AppData QT related WIPED clean as well.
- NDK/ SDK everything installed anew
- same stuff on a fresh VM (like I've explaiend)

If you mean you have purchased a commercial licence from TQtC you can raise your issues with them for their attention.
If you are using the free, open source version then that is not available and here we are just other users of Qt like yourself.

Now, it does not come with technical support (as it tuned out).
As we've learned the hard way that is.
Now, I've forced GDB manually to neglect any segmentation faults (!!!) and Sig33s (..) by typing the custom arguments to QT Creator by hand as copy-pasting would result it to CRASH.
Now I'm able to debug.. I'm not disturbed by QT's internal segmentation faults... I presume? correct me if I'm wrong

Ah, I did not know about that licence's terms.I'm not sure whether in "QT's internal segmentation faults" you mean Qt itself or Qt Creator. I would be worried about either, certainly if Qt code itself in your application is faulting, but I don't know what "workarounds" you need/have to live with for your situation.
Be aware that even without paid support you can raise bugs, against either Qt or Creator, at https://bugreports.qt.io/. People there look at them and respond/fix, regardless of OP's license state. I think Creator is regularly undergoing new releases, I don't know how robust it is for Android stuff.

I know I can.
Then I get to wait 1-2 years till fix-ups make their way into commercial license and another 2 years into open source.
I know.

- we are manually overriding QT's Segmentation Fault events
- overriding Sig33 signals (bionic hardware)
Under the above conditions we are able to debug through QT Creator 12 and GDB with Qt 5.15.16 BUT
- removal of any breakpoint causes the GDB connection to become corrupted.
- no further debugging would be possible
Anyway, we CAN live with that (hopefully).
The most pressing issue is - how to force the mobile app to actually wait for QT Creator to fully attach?
I don't know the details but it seems that QT Creator 12 attached through GDB, the app knows.. BUT... NO BREAKPOINTS WOULD FIRE FOR 2-3 minutes at all (creator would keep showing that it's still attaching during that time period).
