Hi Everyone
I made an simple AR test app with one marker and one object on OpenSpace 3D Editor Windows version then exported it for Raspberry.
I was on Jessie version of Raspbian and had a libcui18n.so problem (Jessie version is 52 and 57 was expected)
Switched to Stretch - problem fixed.
I had the Stretch OpenGLES names problem and fixed it thanks to rpi-update
From this point til now when I start the app I have a white screen with a button in the bottom center with no text in it that closes the app when I click on it
There's a problem with QFontDatabase as you can see in this log

QObject: Cannot create children for a parent that is in a different thread.

/usr/bin/test-ar-pi : ligne 2 : 1175 Abandon sudo /usr/share/test-ar-pi/test-ar-piI made errors about QFontDatabase disappear by creating the folder the app expected (even if I know that the problem is not really fixed)
Now the error about QThread is still here and I still have the white screen with the no text button. The camera LED stays off.
config.txt includes the start_x=1 so I assume the camera is on (I tested it with picamera - the camera did show up and the camera LED was on)
config.txt also includes the gpu_mem=256 instead of 128 as I noticed thanks to this forum that it could be a source of errors.
From what I read on the net this QThread error seems to be due to Qt5 but I don't really know what to do now.
If somebody's got an idea...
Thanks everybody
Ayu
