Qt app without window manager.
-
Ok, but why is qt still trying to use xcb, i built it for linuxfb?
My build configuration is:
@./configure -opensource -release -force-debug-info -confirm-license -static -qt-sql-mysql -qt-zlib -qt-libpng -qt-libjpeg -no-openssl -no-pch -linuxfb -nomake examples -nomake tests
@ -
Just wild guess, but it might be that linuxfb is built additionally to xcb
-
I just finnished rebuilding a fresh copy and if put -no-xcb the compilation fails with error:

Did you cleanup before rebuilding ?
-
Did you try with -qpa linuxfb ?

@It is building now, fingers crossed.

So far so great.
I built twice. It failed the first time because i forgot to ommit the webkit, pfff.
The second time it build perfectly with the above configuration. Thanks SGaist.
So i quickly built a simple gui app and copied it in the target system and voila a window appeared :) .
But, still a but, i don't have a mouse and keyboard. And the system is stuck at this point.
-
Great !
You can also move/remove the webkit folder if you want to avoid that.
Are both detected on your target system ?
-
What kind of device is reported ? (/dev/mouse or... ?)
-
Then you might need to setup that information before starting your application but I don't know if Qt 5 has the same set of variables / command line options as Qt 4 for that, sorry.

Ok, thanks a lot. You've been very helpful.
I will start a new thread for this problem.
Edit: Follow "this thread":http://qt-project.org/forums/viewthread/31911/ for mouse and keyboard problem.
