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

# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Refer to the documentation for the

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)

@J.Hilk

not work this is the simple project, I feel like I'm crazy, I compiled for Android Arm,and work with QT 5.12.2

[KroMignon]

@Nio74 like @J-Hilk has written, QZXing works fine with Android. I've used it a little project.

Important: You have to set CONFIG += qzxing_qml, before include(QZXing/QZXing.pri)!

If you want to use filter capabilities: CONFIG += qzxing_qml qzxing_multimedia

qzxing_qml qzxing_multimedia

so it works thanks, now I have to let the camera read the barcode let's see if we can study a bit, if anyone has any help it's welcome;)
