openembedded-devel@lists.openembedded.org is better place (see README

I've no experience with wandaboard, but few people asked about it with
relation to qt5, so maybe someone will respond on ML.

This works on my SabreLite which I built without X11 support.  I did not
use any of your QT_xxx exports, only this command line.

   # Qt5_CinematicExperience -platform eglfs -plugin tslib:/dev/input/touchscreen0

Same works for Wandboard. I have one customer using it.

Not sure what omap3 board specifically that is, but meta-qt5 was successfully 
tested on another TI platform with OpenGLES on SGX - AM335x. No X11 though.

meta-qt5

[Jacob Stiffler]

It appears that the meta-qt5 layer has dropped the 5.4.1 versioned 
recipes. This means that the meta-arago bbappends no longer apply.

I see there is a history of meta-arago using the versioned recipes, but 
these are no longer there, and only the git based recipes remain.

I'm not sure of the impact there would be in moving the meta-arago 
appends to the git based recipes. I'll give this a try and provide an 
update later.

Yeah, saw this last week, but haven't had a chance to fix it.

What I'm thinking is there are 2 options:

1. Rename bbappends from 5.4.1 to git - seems to build fine locally here.

2. Lock meta-qt5 on the commit before 5.4.1 got removed - it won't get much 
better in 5.4.x branch and we are waiting for 5.5 to get better Touchscreen 
support. We can keep using meta-qt5/master in meta-arago/master, but lock 
meta-arago/daisy to 5.4.1, which is what has been tested so far. This seems 
safer for the release...

Thoughts?

I agree that #2 sounds safer at this point.
