From: Naumann Andreas <ANaumann@ultratronik.de>

Since Qt 5.8.0 provides a software rasterizer we can enable Quick for non-GL
platforms. However, some modules provide less functionality without OpenGL,
so install steps have to be limited for the softrender only backend:
- qtmultimedia does not provide qml

 This means that the conditions that are added to be able to select
BR2_PACKAGE_QT5DECLARATIVE_QUICK are no longer correct (e.g. in
qt5quickcontrols). Since the condition is a bit complicated, it's probably
better to add an auxiliary symbol:

config BR2_PACKAGE_QT5DECLARATIVE_QUICK_AVAILABLE
	default y
	depends on BR2_PACKAGE_QT5_GL_AVAILABLE || !BR2_QT5_VERSION_5_6

comment "quick module needs an OpenGL-capable backend"
	depends on !BR2_PACKAGE_QT5DECLARATIVE_QUICK_AVAILABLE

etc.

 Do that as a separate patch that converts all the existing users of
BR2_PACKAGE_QT5DECLARATIVE_QUICK.

 Note that it has to be checked if all the packages that now depend on
BR2_PACKAGE_QT5_GL_AVAILABLE really do work with the softrenderer.

 Line is too long - wrap at 80 characters.

 Just to be sure: if you try to use these QML classes you get a runtime failure,
correct? So the only reason not to copy them is that we know they won't work anyway?

 Arnout

Ok, I'll do that once the new patch set is out.

Yes. I cant quite remember how exactly it failed but it did quite 
harshly. But that was with the beta version. Not copying the qmls of 
course also results in an error message for applications which try to 
include them.
So in the end its maybe not worth it, because it also adds maintenance 
effort in case it is fixed upstream sometime in the future. Going to 
remove that part.


regards,
Andreas

Dear Andreas & All,

just to avoid duplicated efforts: are you planning to work on this
series and prepare the next iteration? I can dedicate time to this
tomorrow morning earliest, so then either i can start to assemble the
patchset based on the collected comments, or test it if one is submitted
in the meantime...

Thanks,

Zoltan Gyarmati

Hi Zoltan,
i was going to wait for yesterdays subset of Thomas to appear (on 
master?) and then post/rework the sw-rasterize specific patches on top 
of that.

regards,
Andreas
