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

MaximAlien

Thanks a lot sierdzio. I'll ask him. If there is any progress with this issue I'll post solution here.

Hi,

Unfortunately, I know nothing about Mac or this deployment tool. Thiago mentioned on IRC that from the logs it looks like it's unable to find the QtQuick plugin (the QML import plugin) even though it's finding the QtQuick library (the library is what is shown in the logs).

The plugin src is from qtdeclarative/src/imports/qtquick2
It's installed to the QML2 plugins directory (which can be specified via QML2_IMPORT_PATH

I don't know where that tool looks for the plugins, but the default install location is something like QT5DIR/qml/QtQuick.2 (or maybe QT5DIR/plugins/qml/QtQuick.2 I can't remember - oops).

Cheers,
Chris.

MaximAlien

Thank you for your reply Chris. I'll try to manually copy all needed plugins and libs.

MaximAlien

Hey,

This is working solution for deploying QML applications on MAC OS X: https://github.com/MaximAlien/macdeployqtfixed.git

Hope it helps you guys.

hi Maxim, is there any way to get it works with QT 5.1 ?

Struggling with the same issues, can't deploy QtQuick app on Mac

MaximAlien

Hey,

Did you test code I provided? I tried deploying it for Qt 5.1 only once and there were some issues with paths. I'll try it more this evening.

If I manage to deploy it correctly I'll write here.

Cheers,
Max.

I'm testing it know, there is issue with a path, but I'm applying work around I described "here":http://stackoverflow.com/a/17591828/2370437

If I will manage to deploy, I will post here

Does not work for me.

macdeployqt MyApp.app/ -qmldir=../src/qml/

dynamic links information is changes inside executable and QtQuick modules were copied into the app bundle, near executable. But still getting an error:

main.qml:1 module "QtQuick" is not installed

Maybe it is connected with QML_IMPORT_PATH variable, or we need to specify somehow where application can find QtQuick modules

MaximAlien

You suggested this hint sierdzio, thanks.

I tried it a couple of months ago and it doesn't work for me, even more it was updated Mar 19, 2013 9:43 AM, before Qt 5.1 release.

Cheers,
Max.

sierdzio

Yeah, not sure why Ivan suddenly went silent on this.

MaximAlien

miks131 you can try setting QML2_IMPORT_PATH in application pro file, this may help.

I'm using CMake ( have a lot of different components)

Made a quick check.
Tried to add a link to the directory which contains QtQuick and QtQuick.2 folders after deploy.

@engine.addImportPath( QLatin1String("/Users/username/Projects/MyApp/bin/MyApp.app/Contents/MacOS/") );@

Does not work, the same result if I specify two path to QtQuick and QtQuick.2 folders

MaximAlien

Path is correct for QML plugins.
Did you try copying all frameworks and plugins manually?

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.

miks131

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.

miks131

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.

miks131

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
