Hi! I have compile the gui program by QT5.9 (sudo apt install qt5-default). The compiling complete finely at lxqt and debian9:
sudo apt install qt5-default cd program_directory make clean make *At lxqt, the binary program runs finely*. But lxqt take up too much space, so I need in debian9. But at debian9, running the binary file returns an error: *QXcbConnection: Could not connect to display* I have made: *export DISPLAY=:0.0* *sudo apt install libffi-dev phantomjs gksu xserver-xorg* But the error is still present. Also I can run the gui program at debian9 from another PC by: ssh -X 192.168.X.X -l debian but this doesn't solve the problem. P.S. I was advised here, and then my topic was deleted: *You are going to have to add enough stuff to provide, at minimum, an Xserver implementation -- and most likely you'll need a window/desktopmanager.* *The xserver is installed.* Please help. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
