It looks incomplete
-
they have other plugin but i didn't take it because i tougth that two plugin it's necessary to know if i use xcb,linuxFB or EGLFS or other. All other plugin seemeds to Qt object... Do you want the complete result or i need to check some specific plugin?
-
You should check for the entries that start with
loaded library, you'll have the information you seek. -
if you are not root you need to add sudo :P tanks i try this
@CrazyCreepy said in Cross compile dont gen QLabel and QPushbutton and Fontconfig pre-condition:

Sure. But the question was: why do you need to start your app as root?
-
thats all of load library i have found.
loaded library "/usr/local/qt5/plugins/platforms/libqeglfs.so"
loaded library "/usr/local/qt5/plugins/egldeviceintegrations/libqeglfs-brcm-integration.so"
loaded library "/usr/local/qt5/plugins/imageformats/libqgif.so"
loaded library "/usr/local/qt5/plugins/imageformats/libqicns.so"
loaded library "/usr/local/qt5/plugins/imageformats/libqico.so"
loaded library "/usr/local/qt5/plugins/imageformats/libqjpeg.so"
loaded library "/usr/local/qt5/plugins/imageformats/libqsvg.so"
loaded library "/usr/local/qt5/plugins/imageformats/libqtga.so"
loaded library "/usr/local/qt5/plugins/imageformats/libqtiff.so"
loaded library "/usr/local/qt5/plugins/imageformats/libqwbmp.so"
loaded library "/usr/local/qt5/plugins/imageformats/libqwebp.so"so with this it's seem i use the eglfs backend. Now i can't tell if it's normal or not...
and jslum in ancien projet on a raspberry pi i always need to need to be root to start a application ... so i tought it's always like this but it seems that isn't necessary.

Ok, so it means no window manager.
Can you post an image of what you are getting exactly on screen when running your application ?

@SGaist so what this is mean?
-
Firat thing, you won't have any window decoration. The EGLFS plugin only works in full screen mode.
Can you test the LinuxFB plugin ?
-
I have some new. I finally have the push button on my raspberry pi... but the label still missing. Some one give me a program that work correctly on another raspberry pi, but I have the same issue so think it's missing file on my rasp... but i don't understand why i use "apt-get install qt5-default" to install the lib....
how i do that? also all programme i run in full screen mod.
-
How are you positioning them ?
-
@SGaist positionning them? who is them? I'm confuse... and i don't know how i can test the linuxFB plugin...
@CrazyCreepy How do you position the widgets (label and button)? Do you use layouts?
-

@jsulm no i juste use Qdesign and drag and drop.
-
Then you should put them in a layout in your main widget.
-
@SGaist I never do that on windows and it's work.Also, the text on the pushboutton not appear and if i add a another widget like a jauge the pourcent doesn't appear... i try to uninstall qt5-default package and reinstall it, I have also upgrate all package, but it's not work.
-
@SGaist I run my program with this commande ./test -platform linuxfb. The result is i have some graphique bug like 2 curso one white and the second is black.If i pass the cursor on windows programs the icons of my task bar appear and the text is always missing. but it's not in full screen.
look the picture:
-
Is it me or are you trying to run an application on the framebuffer while also having Xorg running ?

@SGaist it's possible... i just follow a tutoriel to get a screenshot and they said enter startx and afther when i open my terminal i have lxterminal on it. i though it's normal and i didn't care about it. but if i run an application in the normale terminale it have the same result of the graphic bug.
