How to build QtQuick module in older Qt versions

[VStevenP]

This question is for those who have experience building older versions of Qt from source:

I need to build Qt 5.3.2 from source. I'm cross-compiling on an Ubuntu host for an ARM target. (Sorry, but I don't have choice of Qt version in this situation.)

I wish to build the QtQuick module as part of this cross-compile, but it doesn't do it, even when I use a simple configure line followed by make. It builds many modules, but not QtQuick. Also, QtQuick is not listed in the config summary.

Is there a trick with earlier Qt versions like 5.3.2 to have it build the QtQuick module as part of the build? Or do I need to build it separately?

Data point: When I install Qt 5.3.2 from binaries on Ubuntu 18.04, the QtQuick library/includes are available:
http://master.qt.io/new_archive/qt/5.3/5.3.2/qt-opensource-linux-x64-5.3.2.run

BTW, I am using the following source file:
http://master.qt.io/new_archive/qt/5.3/5.3.2/single/qt-everywhere-opensource-src-5.3.2.tar.xz

Additional data point: I can cross-compile Qt 5.9.9 from source and it builds the QtQuick module no problem...

So, I am just wondering whether there's something special I need to do to build it using an older version of source like 5.3.2.

Hi,

Did you check the configure logs to see what test may have failed that disables that module ?

[VStevenP]

Thanks for your idea!

In qtbase, I see a config.summary. Here's the contents - It does not list any of the QML/Quick features as yes or no. (That's why I wondered if QtQuick module is really part of the "everything" source build.) I also show the contents of config.status at the end.

Please let me know if you'd like to see another log file and what name it would have.

config.summary:

NOTE: Qt is using double for qreal on this system. This is binary incompatible against Qt 5.1.
Configure with '-qreal float' to create a build that is binary compatible with 5.1.

There's also a folder with the test results that you should be able to grep to see if there's anything relevant.

[VStevenP]

Thanks for that. Are you talking about config.tests? I see some Qt project code in there, but it's not built. This is not related to the -nomake tests configure option, hopefully.

Here's what I see:

If you can think of the name of the folder or files I should be looking for, I'd be glad to search them for errors. I can also increase my terminal capture and post all the configure output, or at least try to look for some clues.

[SGaist]

Let's start again:

• nuke your sources as they now contain artifacts
• extract them fresh
• use an out of source build

The out of source build allows you to keep your sources clean and it will also contain less stuff to inspect after the configuration step.

My Qt 5.3.2 out-of-source cross-compile completed fine, but there was no libQt5Quick.so target built and written to qtbase/lib. Also, there are no QtQuick headers in qtbase/include.

This differs quite wildly from what the Qt 5.3.2 installer binaries provide on Linux. The versions differ so much that I don't think it's really configure differences. Maybe it's down to open source vs commercial option, or some sort of deployment differences that makes them vary so much.

Let me know if you'd like to see any directory listings. I can't identify any config log results files.

Here's an archive of the out-of-source build folder for your perusal. Let me know if you have any additional ideas.

And thanks again for your help.

The out-of source build did generate some other libraries which it didn't publish to qtbase/lib. Here's the list. It includes Qt5Qml.so, which should have been published to qtbase/lib.

Also, I have a theory that the missing QtQuick library may actually be the QtDeclarative library which is perhaps renamed and copied as part of a deploy step. I found a clue in the 5.3.2 source tree:

OpenGL is a requirement for Qt Quick 2 with this release.
https://code.qt.io/cgit/qt/qtdeclarative.git/tree/src/src.pro?h=5.3#n6:

qtHaveModule(gui):contains(QT_CONFIG, opengl(es1|es2)?) {
SUBDIRS +=
quick
qmltest
particles

qtHaveModule(widgets): SUBDIRS += quickwidgets

}

The software renderer arrived several minor releases later. If Qt 5.3.2 without OpenGL is a real requirement, Qt Quick 1 (aka QtDeclarative) is available.

@jeremy_k That is a golden nugget of information right there . Thank you.

In Qt 5.3.2, the only thing that was seemingly requiring me to list the quick module in the pro file my app was my use of QQuickItem. I was trying to inherit from QQuickItem and expose that class to QML via qmlRegisterType(). When I did not try to inherit from QQuickItem and expose that class to QML, my app was actually working on an ARM hardware that has no GPU using Qt 5.3.2. Perhaps it was falling back to QtQuick1 for software rendering even though all my QML imports were for QtQuick 2.0.

Thanks very much for your thoughts.

[jeremy_k]

I am unaware of any fallback mechanism from Quick 2 to Quick 1. Version 1 was implemented on top of the graphics view stack, which in turn uses widgets. The libraries an application would link to are different. Failing to account for that should lead to a build failure. By any chance is this application using a software OpenGL implementation?

Changes to the QML language and Quick items are covered in the QtDeclarative link about, with a focus on moving from version 1 to 2. They aren't significant. Going the other direction could be harder.

[VStevenP]

@jeremy_k OK, I think I understand now. Please correct me if I am wrong.

1. If I need to use QtQuick 2 and also need the Qt Quick 2D Renderer (due to no GPU) , it looks like I need to use Qt 5.7 or higher, because that's when the Qt Quick 2D Renderer became available. (I could configure with -no-opengl and -linuxfb, for example.)

2. If I want to use QtQuick2 with OpenGL ES2 (due to GPU with Open GL ES2 support), I could use Qt 5.0 or higher. (I could configure with -opengl es2, and also possibly -eglfs for full-screen/single surface if needed.)

Either of those might work.

Another option is one of the Mesa software OpenGL drivers. They will be slower and consume more CPU time than a hardware assisted driver, but may be adequate.

Are you tied to an OS or compiler that had support dropped in more recent Qt releases? After solving this problem, there will be a line of others that have been addressed in newer versions.

[VStevenP]

@jeremy_k Thanks for reminding me about the Mesa option. Yes, I am tied to an older compiler for now. Thanks for helping me understand these Qt versions and their capabilities better.

@SGaist Thanks for your help yesterday.
