Is it possible to deploy a Qt Quick application without Qt Network on OS X?

Question

I have a Qt Quick application using the following modules

QT = core gui qml quick widgets \
    core-private gui-private \
    multimedia printsupport`

which I deploy on OS X. Now my main binary as well as a lot of Qt Qtick plugins show a dependency on Qt Network.

otool -L /path/to/My.app/Contents/MacOS/My

        /System/Library/Frameworks/Security.framework/Versions/A/Security (compatibility version 1.0.0, current version 55471.14.18)

        /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 855.17.0)

The same dependency on Qt Network is found in the following plugins

My.app/Contents/Frameworks/QtMultimedia.framework/Versions/5/QtMultimedia
My.app/Contents/Frameworks/QtMultimediaQuick_p.framework/Versions/5/QtMultimediaQuick_p
My.app/Contents/Frameworks/QtQml.framework/Versions/5/QtQml
My.app/Contents/Frameworks/QtQuick.framework/Versions/5/QtQuick
My.app/Contents/Plugins/audio/libqtaudio_coreaudio.dylib
My.app/Contents/Resources/qml/QtMultimedia/libdeclarative_multimedia.dylib
My.app/Contents/Resources/qml/QtQuick/Controls/libqtquickcontrolsplugin.dylib
My.app/Contents/Resources/qml/QtQuick/Dialogs/libdialogplugin.dylib
My.app/Contents/Resources/qml/QtQuick/Dialogs/Private/libdialogsprivateplugin.dylib
My.app/Contents/Resources/qml/QtQuick/Layouts/libqquicklayoutsplugin.dylib
My.app/Contents/Resources/qml/QtQuick/PrivateWidgets/libwidgetsplugin.dylib
My.app/Contents/Resources/qml/QtQuick/Window.2/libwindowplugin.dylib
My.app/Contents/Resources/qml/QtQuick.2/libqtquick2plugin.dylib

1. Is it possible to use Qt Quick without Qt Network?
2. Is there any module dependency documentation for Qt?

I don't get why the dependency in Qt Network is compiled into my own binary.

Answer 1

No.

Proof

The following command line script generates a dependency list of Qt5 modules on Linux:

# Run in e.g. Qt/5.4/gcc_64/lib
for f in libQt5*.so; do mod=$(basename "$f" .so | cut -c "7-"); echo "$mod"; ldd "$f" | grep "libQt5" | cut -f 1 -d">"  | tr -dc "a-zA-Z0-9.[:space:]" | cut -d"." -f 1 | sed 's/libQt5//g'; done

which results in the following output:

Answer 2

Well, QtQml depends on QtDeclarative which depends on QtNetwork so I doubt you can...

And for you, here is the Qt Library Cross Dependencies

Answer 3

The only option for you is reconfiguring and rebuilding Qt.
You can customize available features and get rid of lots of stuff without breaking license.

I didn't do it for long time so I don't have details (I've lost link to best instruction, if I find it I will let you know). I hope that documentation above will be enough. I'm sure you will be able to find some better instruction with Google.

Answer 4

I don't get why the dependency in Qt Network is compiled into my own binary.

If you statically link your program with Qt, the resulting executable should only contain a copy of the library routines called, not the entire library.
