edu.mit.csail.uid has to be replaced by org.sikuli.script when using sikuli-script.jar in Java

seems to be a problem with the NativeLoader in the situation, when using sikuli-script.jar in the standalone version (e.g. directly from Java)

I tried the proposed solution in Bug #694771, renaming the .so libraries in META-INF/lib (in the sikuli-script.jar) to either .jnilib or dynlib, but it did not work. :-(
I think I'll need solution to that bug.

I'm not sure why this happens on Linux. Can you help me to identify the problem?

Can you try to add the path to "the-path-to-sikuli/Sikuli-IDE/libs" to LD_LIBRARY_PATH and see if it works?
If not, try another way: in the working directory of your java program, create a symlink named "libs" pointing to the-path-to-sikuli/Sikuli-IDE/libs.

Let me know if any of these methods works for you.

I tried adding LD_LIBRARY_PATH, but it did not work..
LD_LIBRARY_PATH=/opt/sikuli/X/Sikuli-IDE/libs java -cp /opt/sikuli/X/Sikuli-IDE/sikuli-script.jar:target/foo.jar com.spotify.qa.foo.App

And I just repeated the same error on a Windows box. (running under cygwin). Go figure...
I used the same version as for Linux, that is X-1.0rc1

Could it be that the method Vision_initOCR is getting an empty string?

Oh, I see the problem. The java package in X have been changed to org.sikuli.script. So you need to replace all "edu.mit.csail.uid" to "org.sikuli.script".
Sorry we haven't updated the java doc yet.

Yupp! That's it! Changing to org.sikuli made it work.

But, why did it compile using edu.mit.csail.uid?

I guess the JAR in your CLASSPATH is not cleaned. It still has the old class files.

Hmm, if you look in the sikuli-script.jar, there actually exists /edu/mit/csail/uid/*.class files. I guess that's the old stuff?

yeah, they are the old things and should not be there. We will fix this in the next release.

Anyways, thanx for all help!!

Am running Sikuli on EL6 Linux 64 and recorded something to start. Went to playback and got a link error:

Opened up the /home/fahome/tkessler/sikuli/sikuli-script.jar/Lib/sikuli/Sikuli.py file in Ark and noticed all kinds of edu.nit.csail references. Do I need to replace these to "org.sikuli.script" like you mentioned above?

Hmm, tried that and it didn't work... downloaded the X-1.0rc1 version and now get this instead and stuck:

You need openCV 2.1 installed as mentioned in the prerequisites.

and you have to remove all 10.2 stuff completely!

BTW: when posting a comment to an exisiting question, subscribe yourself to the question, to be notified when commented.

I deleted the directory from my previous installation. Checked to be emailed for future discussion too...

Found OpenCV and downloaded it. Looks like lots of source code and I don't see how to install it or installation instructions for Sikuli Linux anywhere on the site am I missing it?

Can you help me step by step of what I need to do to get Sikuli to work on Linux 64?

Thanks,

Tom

Uuups, I do not have Linux (only Mac and Windows, no need to install openCV, it is in distribution).

A few month ago I tried to install openCV on my Mac (at least Unix like) and finally succeeded. all I had was the information at: http://opencv.willowgarage.com/wiki/FullOpenCVWiki.
I used the cmake approach using the source. On Linux this is definitely easier than on Mac ;-)

And you need the actual Java JRE, but I guess you have it already.

Then sikuli-ide.sh should bring up Sikuli IDE. Good luck.

If you really need help, you should post a new question with as many information about your environment and situation as possible. More than 300 downloads of the Linux 64-Bit version are out there now.
