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 )
I don't have access to your configuration (I only have a Pi with HDMI), so this
is going to be hard for me to help with. You do need the sudo because of the
permissions issues with the input devices.
When Daniel added the code to mentioned in RT-36960, he did not have that
configuration either, so we will need help understanding what is happening.
You might try adding -Dprism.verbose=true -Djavafx.verbose=true
and we might get lucky.
pi@raspberrypi ~ $ java -Djavafx.platform=monocle

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

Nick found a good one, took me a while to find the obvious :-p
The UnsatisfiedLinkError was caused by old ARM JFX jars that were not
overriden when he copied the new bits into the JDK.
On ARM we have a split set of jars for FX that we ship, but when we build,
we only build the single jfxrt.jar like the desktop. The split is post build
packaging. So Nick was mixing old and new jars, which is what the Wiki told him
to do. Doh.
I updated the wiki for OpenJFX building and cross building with some
clarifications, notes and such, so hopefully the next solider will not find so
many mines.

So I made some progress here:
I had installed Ubuntu 14.x 64-bit version. Once I installed the

So then I figured I try and get an Ubuntu 12.x 32-bit VM up and running
and
use that for a OpenJFX build since this is mentioned in the OpenJFX
wiki.
However, a clean install cant run sudo apt-get update due to missing
package definitions - have Ubuntu (or whoever maintains this set of
repos)
removed the older 12.x packages (or started to)? I cant get gcc
installed
or updated because of this - and this is a fresh install direct from the
Ubuntu 12.0.4 .iso
On a related note, its not clear to me what Im supposed to do after
compiling OpenJFX - what needs to be installed and where does it need
to go
- JAVA_HOME/jre/lib ? (just replace everything in there?)
