Unable to debug Android App (Windows + Qt Creator 12 + LLDB)
-
@CodesInChaoss maybe you are using LLDB the wrong way with qt.
Also, have you checked if it is the right version for your Qt version?
How have you first of all added lldb in qt? which versiion of lldb are using? -
Everything comes with defaults delivered by QT Creator 12, clean install of Windows.
-
@CodesInChaoss LLDB is for linux, use GDB for windows
check this https://doc.qt.io/qtcreator/creator-debugger-engines.html -
yes I've seen this page already BUT it seems that recent versions of QT Creator enforce use of LLDB (also by default) on WIndows. There are tickets in Bug-Reports saying that they've 'transitioned'.
I've always worked with GDB on WIndows with QT Creator, but to all my surprise, after installation of QT Creator 12 (we've transitioned to Commercial License) LLDB was selected and enabled BY DEFAULT on all kits.
So I said to myself, ok - let's go. I knew LLDB was for mac since that's what we've been using for iOS deployment.
lldb version 11.0.5 clang revision 87f1315dfbea7c137aa2e6d362dbb457e388158d llvm revision 87f1315dfbea7c137aa2e6d362dbb457e388158d -
As far as I know, LLDB never (before) came pre-installed on Windows installations alongside with QT Creator, I think.
Now, on windows , all kits deployed by QT Creator , by default have this:
-
@CodesInChaoss Do you mean that you have installed lldb with the online installler?
-
@Ronel_qtmaster
Well it must have arrived with the online installer, yes, by default since I've used all the default tickers which go for Qt 5.15.16 -

When I choose GDB rebuild the app none of the breakpoints are ever hit GDB reports version 8.3 ( installed by Qt I presume).
The effect with GDB is that the app waits for debugger, the app runs (the breakpoints I set are not hit - in main())
yes yes, it works I'm not a noob, the app has been tested by thousands already.
-
It's like I've had everything set up and running perfect but something made me update from QT Creator 10 (community edition) towards QT Creator 12 and here I am.
-
seems as both LLDB and GDB come as part of Android SDK/NDK so these have been installed by QT Creator itself during Android bootstrapping (autonomous).
These things do not come as part of the Online Installer.
-
Can anyone else confirm that we are STILL to be using GDB on Windows with QT creator when debugging Android apps, please?
I'm more than fine with just about anything that works.
-
@CodesInChaoss Qt does not install android sdk and ndk during update.You have to do that externelly so if you have updated Qt it might be possible that your ndk version is conflicting somewhere
-
my friend,
Above, for a couple of YEARS now.
And I've been using QT when nothing fancy like that was around trust me when I say.
-
I've been seeing lots and lots of deep sh** when it comes to QT... I've been deep down. Trust me when I say, it's all doomed but I love it but only because I'm a low-level type of a guy.. I can't possibly IMAGINE any typical developer using it. I simply cannot. Not for mobile. And not from WIndows.

Dear Ronel I'll tell you that I've even got GDB 'working' for me but it took quite a few ADB commands and manual creation of folders on my Android device, now tell, me is this a unified QT Multi-Platform Development framework?
How a typical developer is supposed to get around these issues?
Why LLDB set by default?
Now I know it's not QT support.
Anyway I'm still looking into making the android app actually not skip the initial breakpoints.
-
When running the app under GDB (Xiaomi device) I'm getting SigSegvs in a thread named "ScoutStat" asm code.
Anyone knows what this might be? It's not part of my app, the app runs fine.
-
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 ?
