Building Openjfx on Centos 6.6

[Nick Pratt]

Thanks for the help.  So now I can invoke Java without the link errors, but
my JavaFX app isnt appearing on the attached TFT screen ( Note: I can get
'x' to appear on the the Pi TFT screen by setting the FRAMEBUFFER variable
prior to invoking startx so I know my TFT screen is setup and the right
Kernel mods are enabled and applied)

Notwithstanding the error messages below, am I invoking Java correctly here
: (based on the comments in https://javafx-jira.kenai.com/browse/RT-36960 )

pi at raspberrypi ~ $ java -Djavafx.platform=monocle
-Dmonocle.screen.fb="/dev/fb1" -Ddispman.display=0 -Ddispman.layer=1 -jar
JavaFXApp.jar

Udev: Failed to write to /sys/class/input/mice/uevent

      Check that you have permission to access input devices

Udev: Failed to write to /sys/class/input/event0/uevent

      Check that you have permission to access input devices

Udev: Failed to write to /sys/class/input/input0/uevent

      Check that you have permission to access input devices

Udev: Failed to write to /sys/class/input/mouse0/uevent

If I run the above command as sudo root, then I dont see the errors
printed, but still nothing on the TFT screen.

Regards


Nick
