[SOLVED] BB10 official support for Qt 5.x
-
I'm sorry I just edited my post with additional information while you posted.
I will be updating the wiki pages to give a better explanation as how to test and deploy Qt5 applications with the Overlay today.What Operating system are you on?
If you use the overlay and the commands I outlined (they are explained in make bbhelp) the Qt5 runtime will be packaged into your application and will run without requiring a Qt5 runtime installed on the device.
Applications created in that way are perfectly suitable for submission on blackberry world. -
@AlterX: Moving the whole platform to a new, non BC (Qt5 vs Qt4) version of one of the base layers (as Qt4 in BB10) is not a quick and simple thing you do in a rush. Moreover, there might be other, more important tasks for many teams. Like any platform, BB10 wants to be attractive for end users and for developers. Qt (4 or 5) is only a part of the whole picture, important part, but still a part. Qt is an exciting technology and Qt5 is its top edge, but this is by far not the only thing the market expects from a mobile platform.
If you wanna use Qt5 for app development you are better off using a pre-built package. It is better for BB10 as a platform too, since we can channel all apps using one base and not multiple self-made versions.

Hi Vladimir, yes I know Qt is just a part of a big plan, but:
-
Qt 4.x on blackberry are close to be unusable (I have just ported a stupid app, but more complex apps were impossible to port due to lack of many objects and graphics effects)
-
Think about Jolla: they did all big plan (a new operatin system, innovative UI, the best android virtual machine ever, full Qt5 support as runtime and sdk, TOH sdk, complete store and platform to publish apps ,
many OS updates and last but not least they worked hard to ship all pre-ordered devices by themself) in just 1.5 years with 100 persons...
I think RIM is just a little bit bigger then Jolla...

Coming back to the original topic of this thread. Due to the way how applications are installed on BB10 and permissions are structured, a slide-loaded Qt run-time works the same way for an app carrying it as the one which would be provided as a part of the firmware. So side-loading should not be a reason to not using Qt5 for app development on BB10.
-
Coming back, since I have seen Qt 4.x runtime within firmware, I was thinking of some delays on Qt 5.x
But right now swoz told me about the ability to bundle runtime with app (so publishing on BB10 is possible), I feel good since it is still possible to work on BB10 using the new Qt 5.x
-
I wanted to add one more thing that for testing you need not to bundle Qt libs with app. using Qt Creator 3.1 beta it got too easy.
it will copy all your libs, plugins, to /accounts/devuser folder so in bar-descriptor give the path and enjoy. http://qt-project.org/wiki/Qt-Creator-with-BlackBerry-10 may help you -
I'm trying to configure the Qt 5.x package under QtCreator...it's very difficult...I have tried on 3.0.1 and 3.1 beta, but nothing.
I'am using "install new target" facilities and even it tells me installation was successfull it doesn't configure nothing!
I am trying to install manually, but I got big problems on path of qmake.exe and similar....
How Do I achieve this? -
It is worrying that you write you "replaced the original directories with overlay ones". You have to copy the overlay content into the original folders, and not replace them.
Moreover, QtCreator 3.0.x is will not recognize the additional content provided by the overlay as long the NDK is not deactivated and activated again. If 10.2 Gold is the only NDK you have, you should download and install one more version of the NDK to do the activation trick, since it is not possible to deactivate a single NDK instance. This will be improved in the upcoming 3.1. This and the previous point are mentioned in the README of the overlay, BTW.
If you continue experience problems please file an issue as noted on wiki and in the README.
Regarding your question "if it is possible to publish a Qt 5.x app on BB store". There are multiple Qt5 apps in the store since a long time. Some of them are even based on Qt 5.0.
-
I have configured all and seems correct, but when I deploy just a starter BB project, after compilation, QtCreator shows me:
@
Error: Failed to create application process: Exec format error
@target is qnx6 and I am trying to deploy to well-configured BB z10
-
The qnx6 target actually consists of two different ones: arm (device) and x86 (simulator). You probably managed to deploy an x86 binary on Z10.
-
ah, one more thing. Watch if a qmake and a compile run is restarted after you had switched from one target to another. I remember the were cases that QtCreator did not notice a change in the kit and did not restart qmake and build accordingly.
