I read and followed the tutorial in subject http://www.udoo.org/ProjectsAndTutorials/how-to-build-qt5-for-udoo. I wanted to write a comment as the author wrote at the end of the tutorial but I have not found a way, so here I am. I followed the tutorial and it worked. I can compile and launch qt application but i found some problems. The bigger problem i have is caused by the console or the window manager trying to paint over the GUI of the Qt program. When i launch the Qt program from the console (CTRL+ALT+F1), every time the console updates it paints over the GUI of my program. This means i can see the console cursor blinking or every debug message my program prints to the console. I tried disabling all the /dev/ttyn and launching the progam throught ssh but the console cursor blinking is still visible. Am I the only one facing this problem? Have someone a solution? I tried to compile qt5 for the debian image but failed, any chances to have a similar guide for the armhf debian image?
