Cross build JavaFX for iMX6

Tue Jul 7 21:13:51 UTC 2015

Hi all,

I'm still trying to run JavaFX on iMX6 using fsl-image-gui image from Yocto
Dizzy with DISTRO_FEATURES_remove = "x11 wayland directfb". After compiling
the image and javafx I tried to run Modena.jar with the script provided by
Jörg.

I'm facing this exception:

Java HotSpot(TM) Client VM warning: You have loaded library
/opt/armv6hf-sdk/rt/lib/arm/libjfxwebkit.so which might have disabled stack
guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c
<libfile>', or link it with '-z noexecstack'.

(Possible cause: architecture word width mismatch)

So I browse to fresh built sdk, and find this:
[geckos at csi24 build]$ find . -name "*.so" -exec file {} + | grep x86-64

It seems that this libraries ar not being cross compiled, is that normal?
The another libraries seems good:

To compile run this:
gradle -PCOMPILE_TARGETS=armv6hf
