NoClassDefFound error when trying to find or wait on 14.10

[Brian Redmond]

I've been trying to get 1.1.0 to work on Ubuntu server 14.10. I've followed all steps in the quickstart to compile both the libvisionproxy and jxgrabkeys and compiled both successfully. I can launch the IDE, run a script with a print statement, save scripts, capture new images and perform actions without images (click()). When I try to perform an action with an image, though like a find or wait, I get:
[debug] Region: find: waiting 3.0 secs for 1417554698482.png to appear in R[0,0 1024x768]@S(0)
[debug] Image: reused: 1417554698482.png (file:/home/editshare/sikuli-test.sikuli/1417554698482.png)
[error] script [ sikuli-test ] stopped with error in line 2
[error] java.lang.NoClassDefFoundError ( java.lang.NoClassDefFoundError: org/sikuli/natives/VisionProxyJNI )

[RaiMan (raimund-hocke)]

Sorry, but I did not have time yet, to test the native build on Ubu14 nor to make a working build package for version 1.1.0.

It might be a problem with OpenJDK.
Any chance to test with the original Oracle JDK?

[Brian Redmond (bredmond)]

No problem, to be careful I reverted to a snapshot before installing OpenJDK and instead installed Oracle 7, but had the same problem:

[RaiMan (raimund-hocke)]

thanks for testing.

I guess I have a chance to test and fix it the next days.
