Unable to debug Android App (Windows + Qt Creator 12 + LLDB)
-
So yeah.. so it seems that the signals received previously by LLDB (but QT was not showing ANY dialog-boxes) or the actual Signal Code, are in fact segmentation faults coming from something name 'Scout Stat' Anyone knows what this is?
-
That's not part of my code and something presumably operating as part of QT ?
-
Ok folks so there's that MAGICAL
'scoutstat' thread, I have no idea what it is that is causing havoc.It must be something related to UI/rendering/UI interactions since the segmentation fault would be signaled only as a result of UI interactions/ UI animations/ preparations.
What's that and why the heck it's sig-faulting on meh
Not my code. And presumably not part of source code that arrive with QT pre-installed since QT does not bring me to these.
-
also getting lots of these on dialog-creations.. what the heck is going on here....
-
My 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.
-
Turns out Sig33 is reserved signal issued by bionic hardware. anyone can confirm, safe to 'handle SIG33 nostop noprint'?
-
Loving the overall EXPERIENCE
-
Do I DARE to tap the first button?
-
Why all my KIts' settings get WIPED OUT after the crash?
-
It's like I'm debugging on V8 ABI, I need 64 bit compiler and QT Creator keeps reverting settings back to 32bit compiled actually messing up with my settings.
Now, how a regular developer is even to notice?
-
By the time I reconfigured everything, it turns our Creator is unable to attach due to ADB being in an 'incompatible state. Thus I'm best off restarting the PC...
-
otherwise it would just remain stuck at ```
D libGRIDNEToken_arm64-v8a.so: QML Debugger: Waiting for connection on port 51672...forever -
I'm also getting segmentation faults in 'binder:X' threads on UI interactions.
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.
-
@CodesInChaoss I am pretty sure that it is mostly related to the update process
-
yeah 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.
-
We've bought the 'cheap' startup license or I recall 600USD per year per person.
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
-
Something I haven't seen for like 4 years

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.
