[solved] Unable to deploy Qt Quick 2 application on Mac OS X 10.8.2

MaximAlien

Looks like macdeployqt needs to be slightly changed for Qt 5.1 because using otool utility for dependencies search before and after macdeployqt nothing changes.

App still uses dependencies from system, not in bundle.

There is another bug - executable contains doble slash in path to Qt dynamic libraries. Take a look here https://bugreports.qt-project.org/browse/QTBUG-32379

That's why macdeployqt does not change links. But you can work it around. Just use install_name_tool to get rid of double slashes, before you run macdeployqt.

Well, I did try to copy QtQuick modules manually too.

But not a frameworks, there are a lot of dependencies with linking which has to be resolved by install_name_tool - to get a self contain app bundle. So I'm using macdeployqt for copying Qt Framework.

MaximAlien

I see. Thanks

I'll try to check it this evening.

OK,

there are still troubles even with this work around.

The thing is that there are a lot of dependencies between Qt libraries. For example QtQML depends on Network, Core, V8 ( you can check that by running otool -L ). So QtQML links with them dynamically. macdeployqt suppose to resolve linking paths, from absolute once to relatives. Because we copied all libs inside app bundle. But it does not do it, because of doble slash inside paths for QtQml for example:

@otool -L QtQml /Users/username/Qt5.1.0//5.1.0/clang_64/lib/QtNetwork.framework/Versions/5/QtNet‌work )@

So path to QtNetwork was not changed, and it means bundle will not be distributable, since it depends on absolute paths.

In general deployment of QtQuick modules is a bigger problem, because dynamic linking paths could be modified manually with install_name_tool and there is a "documentation":http://qt-project.org/doc/qt-5.0/qtdoc/deployment-mac.html how to do so.

But there is not any documentation how to deploy QtQuick modules : /
I wrote an email to Qt-Components mailing list, maybe someone will provide useful tip.

So the same story with libraries inside QtQuick and QtQuick.2 folders, it is not enough just copy them inside app bundle.

Dynamic linking paths inside libs has to be modified to a relative once with install_name_tool

"This script":https://gist.github.com/lasconic/5965542 will help to fix duble slashes within QT

This bug reported since Qt5.0.1 come out
"bug report":https://bugreports.qt-project.org/browse/QTBUG-29495

Until now, we still don't get a useable macdeployqt nor any document
show us how to deploy QtQuick2 projects on mac, maybe even the
developers also don't know how to do it?

After I copy the QtQuick2 and QtQuick folders into the plugins folder of the bundle
I run the otool -L on each dylib, the path are relative but not absolute, so what is wrong?
Something haven't changed?Or I missing some dylib?

@MaximAlien great job with macdeployqt on GitHub! Thanks a lot. It works with QT 5.1 after I fixed double slashes with script I mentioned above.

Maybe it is a good idea update README on GitHub

qtnext

It dont' works for me .... I have use the script to fixe the double slashes, use macdeployqt from git ... and it start with a white screen and module "QtQuick" is not installed ....
I don't understand why this bug is not fixed : it seems for me a major show stopping bug : Quick2 is the new way to go and MacOS is a major platform ...

MaximAlien

Finally this macdeployqt problem is fixed in Qt 5.1.1

I’m using Qt 5.1.1, and deploying to OSX, but I am still getting errors similar to these.
Specifically the qml imports:

QQmlApplicationEngine failed to load component
module “QtQuick.LocalStorage” is not installed
module “QtQuick.Layouts” is not installed
module “QtQuick.Controls” is not installed
module “QtQuick” is not installed
module “QtQuick.Dialogs” is not installed
module “QtQuick.Controls.Styles” is not installed
I’m using qtcreator & macdeployqt, but there is not a -qml option. Most sources say the macdeployqt command just works now in 5.1.1, but that still does not seem to be the case with qml. After all the debugging in this thread what is the canonical way to deploy to mac now?

Thanks
