[Interest] Qmake to CMake project conversion android build

Thu Nov 17 07:43:56 CET 2022

To answer this myself: Get rid of all find_package(Qt5...) in CMakeList.txt not containing source files. Only search for qt packages in library or application related CMakeList.txt.

if(ANDROID)
    set(QT_ANDROID_APPLICATION_BINARY EuroSoft_live)
endif()

has to be inserted before find_package() call for Qt library cause of a bug in Qt5 cmake tools that root PROJECT_NAME is used for the Android shared object file. This is fixed with Qt6.

I’m using Qt Creator and in Run EuroSoft live is already present:

Hi,

Do you use Qt Creator to build, deploy and run the application? If yes I would guess you need to switch the "Run" target on in bottom part of the left panel.

Regards,
Alexey.

Hello experts,
currently trying to move from qmake to cmake. Starting point in my Framework was using qmake2cmake tool. This generated a bunch of heavy cmake files, stripped them down and got it working that my integrated internal libs are building on windows.
I have managed to get building and running working under MSVC. Now I stuck with Android, my libraries and UI components in applets are building, also the final shared lib for EuroSoft_live is building but build process stops with following error:
👎 Fehler: Cannot find application binary in build dir D:/Projects/QtEuroSoftProjectQt6/build/Android_Qt_5_15_10_Clang_Multi_Abi-Debug/android-build//libs/armeabi-v7a/libEuroSoftProject_armeabi-v7a.so<https://v7a.so/>.

Project structure:
EuroSoftProject
CMakeLists.txt
- applications
CMakeLists.txt
- EuroSoft_live
CMakeLists.txt
- applets
- libraries
..

Why does the compiler search for libEuroSoftProject... and not for libEuroSoft_live...? When i remove the project tag from root CMakeLists.txt it searches for libProject... The final libEuroSoft_live is already exisiting in build-dir/android-build/libs/armeabi-v7a/...

Do you have any advice for me?

Regards Michael
