Hi,

our project uses our internal qml plugin. If we put plugin binary nad qmldir file manually inside Felgo/Felgo/android/qml/Medrepo and build APK in QtCreator all works as expected and qml library together with Felgo project binary (as .so)  are inside /lib/x86. qmldir is inside /assets/–Added-by-androiddeployqt–/qml/…

Now we trying to build Android and iOS packages using Felgo CI/CD server. We have qml plugin binary inside git repositotry, but how to copy it inside Felgo installation? I tried to put it this way:

android {
    ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android
    OTHER_FILES += android/AndroidManifest.xml \
                   android/build.gradle
    equals(ANDROID_TARGET_ARCH, arm64-v8a) {
        ANDROID_EXTRA_LIBS += \
            $$PWD/../../../deploy_android/arm64/libwebsockets.so \
            $$PWD/../../../deploy_android/arm64/libjasca.so \
            $$PWD/../../../deploy_android/arm64/libjasca_qml_plugin.so             
    }
}

where libjasca_qml_plugin.so is the required QML plugin. It gets deployed inside /lib/arm64-v8a, but app still crashes and I think it’s missing qmldir file. I cannot put it in ANDROID_EXTRA_LIBS.

Since on Felgo CI/CD server I cannot manually copy files, the only possibility is to do all deployment with qmake (inside .pro file).

What is the proper way to deploy QML plugin on Android and iOS?

For Android it seems to work using ANDROID_EXTRA_PLUGINS. If put qml plugin together with qmldir inside eploy_android/arm64/Medrepo, then

android {
    ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android
    OTHER_FILES += android/AndroidManifest.xml \
                   android/build.gradle
    equals(ANDROID_TARGET_ARCH, arm64-v8a) {
        ANDROID_EXTRA_LIBS += \
            $$PWD/../../../deploy_android/arm64/libwebsockets.so \
            $$PWD/../../../deploy_android/arm64/libjasca.so
        ANDROID_EXTRA_PLUGINS += $$PWD/../../../deploy_android/arm64/Medrepo
    }

After that I have qml plugin inside /lib/arm64-v8a and qmldir inside /assets/Medrepo/

What should I do for iOS image?

Hi Volker,

sorry for the delay, I had a bit of back and forth with the development team about this. I followed up to you via mail on this.

Best,

Hi Alex,

I’ve got Mac Mini M1 and trying to get app running in Simulator and real device. AFAIK on iOS I have to use static libraries only, so I compiled qml plugin statically and link it with app:

ios {
    LIBS +=            
        $$OUT_PWD/../jasca_qml_plugin/libjasca_qml_plugin.a 
    QMAKE_INFO_PLIST = ios/Project-Info.plist
    OTHER_FILES += $$QMAKE_INFO_PLIST
    QMAKE_IOS_DEPLOYMENT_TARGET = 12.5
    QMAKE_APPLE_TARGETED_DEVICE_FAMILY = 1
    QMAKE_APPLE_DEVICE_ARCHS = arm64
    QMAKE_APPLE_SIMULATOR_ARCHS = x86_64
    Q_ENABLE_BITCODE.name = ENABLE_BITCODE
    Q_ENABLE_BITCODE.value = NO
    QMAKE_MAC_XCODE_SETTINGS += Q_ENABLE_BITCODE
}

But on startup I’m getting: “​Warning: QQmlApplicationEngine failed to load component ((null):0, (null))” and later “module “Medrepo” is not installed”.

I created resources file for qml plugin:

<RCC>
    <qresource prefix="/Medrepo">
        <file>qmldir</file>
    </qresource>
</RCC>

and put following lines in main.cpp

#ifdef Q_OS_DARWIN
    engine.addImportPath(app.applicationDirPath()+"/../PlugIns");
    engine.addImportPath("qrc:/Medrepo/");
    qmlRegisterType<JascaPlugin>(uri, 1, 0, "JascaPlugin");
#endif

But no success …

I forgot to mention that qmldir was adjusted for static linkage:

module Medrepo
plugin jasca_qml_plugin
typeinfo plugins.qmltypes # required for static plugins
classname Jasca_qml_pluginPlugin # static plugin must set classname for plugin c++ class

 

[Volker]

Inside pro of qml plugin there are some ios specific definitions:

ios {
  DEFINES += BUILD_PLUGIN_STATIC
  CONFIG += static
  RESOURCES += plugin_resources.qrc
  QMAKE_MOC_OPTIONS += -Muri=$$uri
  QMAKE_IOS_DEPLOYMENT_TARGET = 12.5
  QMAKE_APPLE_TARGETED_DEVICE_FAMILY = 1
  QMAKE_APPLE_DEVICE_ARCHS = arm64

}

Hi Volker,

just to be sure, is this related to Cloud Builds CI/CD (which this forum thread was related to) or are you trying to build/deploy locally on your Mac?

Best,
Alex

[Volker]

Changing one line to qmlRegisterType<JascaPlugin>(“Medrepo”, 1, 0, “JascaPlugin”); solved the problem.

[Volker]

Hi Alex,

sorry, I had to create a new thread. We are doing CI/CD on our loacl gitlab runner, so it is not related to Felgo’s cloud build system.
