Qt 5.11.0 compile issue for Android

[Pouria]

Hi,
I’m trying to open a project from github on windows 10 using Qt 5.11 with NDK 17. When i open the project.pro file, i get a warning saying:

C:\Users\poury\AppData\Local\Android\Sdk\ndk\android-ndk-r17c\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-linux-androideabi-gcc” is used by qmake, but “C:\Users\poury\AppData\Local\Android\Sdk\ndk\android-ndk-r17c\toolchains\llvm\prebuilt\windows-x86_64\bin\clang.exe” is configured in the kit.
Please update your kit (Android for armeabi-v7a (Clang Qt 5.11.0 for Android armv7)) or choose a mkspec for qmake that matches your target environment better

And when i try to build the project, i get this error:

linking debug\libQGroundControl.so
arm-linux-androideabi-g++: error: oj\moc_CoordinateVector.obj: No such file or directory
make: *** [debug\libQGroundControl.so] Error 1
00:29:32: The process “C:\Users\poury\AppData\Local\Android\Sdk\ndk\android-ndk-r17c\prebuilt\windows-x86_64\bin\make.exe” exited with code 2.
Error while building/deploying project qgroundcontrol (kit: Android for armeabi-v7a (Clang Qt 5.11.0 for Android armv7))
When executing step “Make

Any suggestion how to solve the issue ?

Hi and welcome to devnet forum

See on https://doc.qt.io/qt-5/android-getting-started.html there you will found following section

Your current NDK version is r17c. Either you install at least an older NDK version or you need to switch to Qt 5.12. I recommend to upgrade to Qt5.12.

@koahnig , thank you for your response, i really appreciate it. i did as you said, the previous error is gone, but i get a new error :

clang++.exe: error: no such file or directory: 'obj\moc_QGCAppliction.obj'
make: *** [debug\libQGroundControl.so] Error 1
22:41:39: The process "C:\Users\poury\AppData\Local\Android\Sdk\ndk\19.2.5345600\prebuilt\windows-x86_64\bin\make.exe" exited with code 2.

how should i resolve this one?

@Pouria

Right click on project and on "Run qmake" afterwards a "Rebuild all". Check if this is helping to resolve the problem.

@koahnig
it shows a new error :

@Pouria

Could be an interference from anti-virus app. You need to check if the AV-app denies access there.

@koahnig
there was no access deny, but anyway i turned off the AV and i still get an error, it's driving me crazy!
what about using qt 5.11 with NDK 10, do you think if i downgrade would it help ?

clang  : error: no such file or directory: 'obj\moc_PositionManagerobj'
make: *** [debug\libQGroundControl.so] Error 1

@Pouria

You can try to downgrade. I have done some tests with Qt5.11.3 and changed to Qt5.12.0. BAsically you could switch forth and back. The only nuisance was the required change of ndk version.

@Pouria ,
Any success? I'm trying exactly the same!
Would like to know how you overcame it, it's driving me crazy too!
Your time is appreciated. Many Thanks!
