HI
I tryed to use QZXing library bat not work good,when I go at declare in the my *.pro I have this problem
D:\GoogleDrive\c++\QT\ProvaNegozioCodeBAr\main.cpp:13: error: 'registerQMLTypes' is not a member of 'QZXing' QZXing::registerQMLTypes(); ^~~~~~~~~~~~~~~~
this is my file *.pro
QT += quick include(QZXing/QZXing.pri) CONFIG += c++11 core qzxing_qml # The following define makes your compiler emit warnings if you use # any Qt feature that has been marked deprecated (the exact warnings # depend on your compiler).

Is there any native library running for android and IOS? I tried to look for some working projects but also those that are like an example are all with old QT version.

@Nio74 QZXing is working fine, if you set it up correctly in your project.
How did you include it? The pri file in your project or as precompiled lib ?
Do you want to use the QML based imageFilter ? I assume so because your error message eis of missing regisetQMLTypes.
My guess is you forget this define in your pro file
DEFINES += QZXING_QML

I have created new project and insert "Src" library in the my project directory renamed it in to QZXing, and this is my complete *.pro file.

in this image you to see my qml and the error

@Nio74 on first glance, I would say you mixed stuff up.
It's defines, not config.
example, directly taken from one of my projects
DEFINES += QZXING_QML include($$PWD/3rdParty/QZXing/QZXing.pri)
