JMyron UnsatisfiedLinkError
Aug 17th, 2007, 12:42am  
Hello,

I'm trying to get JMyron up and running, but am hitting a blocker very early on. Not even the simpleCamera example works As soon as I construct a JMyron() object it crashes with the following error:
Code:

Exception in thread "Thread-2" java.lang.UnsatisfiedLinkError: /Applications/Processing 0125/libraries/JMyron/library/libJMyron.jnilib: 
  at java.lang.ClassLoader$NativeLibrary.load(Native Method)
  at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1751)
  at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1676)
  at java.lang.Runtime.loadLibrary0(Runtime.java:822)
  at java.lang.System.loadLibrary(System.java:992)
  at JMyron.JMyron.<clinit>(JMyron.java:14)

The camera I'm using works using the processing video library, so I don't think that's the issue, although it is black and white.

Thanks in advance.

More digging around, it turns out that it doesn't work perfectly with the normal video library either. The examples all work fine, so it's getting camera data, except if I uncomment the line in GettingStartedCapture that says

Code:

  String[] devices = Capture.list();


it crashes with the error:

Code:

  java.lang.RuntimeException: Couldn't find any capture devices, read the video reference for more info.


I'm on a Mac Pro Intel with Mac OS X 10.4.10

More weirdness! (Sorry about the flood of info)

If I open iChat and look at the video preview it claims "Your camera is in use by another application." and doesn't show me anything. This happens even if I restart the computer and open iChat before anything else. I'm beginning to worry that the camera only sort of works on the Mac or something. It's a Flea by Point Grey Research.

Did you install any software that came with the camera? If you did try removing it or disabling it and restart.

Just my uneducated guess.

The unsatisfied link error can also happen if JMyron is not installed according to the instructions in the zip file. I've made that mistake.

I don't think it's an issue with the camera. I just got a hold of an iSight, and I'm having the same issue.

Is JMyron known to work in processing 125 on Intel macs?

Solved it! It turns out that the native jnilib was compiled only for PPC. Luckily, this guy:
http://www.jibberia.com/projects/
has compiled an Intel version. Now it works.

The site you pointed for the .jnilib file seems hacked. Is there someone that could share the file for intel macs? Thanks a lot!

Same problem here, I can't find this file for download anywhere! If someone can put this up, I will try to host it on my site too.

I had this problem too.
I did change the archive and it worked.

The file you can download it from here: jibberia.com/projects/libJMyron.jnilib.zip

Ah! I am not using Mac,  I am using Windows XP (on a Intel processor) and it still worked fine.

I get an unsatisfied link error but mine is with the JMyron.dll


Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: C:\Program Files\processing-1.0.4\libraries\JMyron\library\JMyron.dll: Can't find dependent libraries

     at java.lang.Thread.run(Thread.java:619)



Im on windows xp. OpenCV works fine as does processing video. Im using 1.0.4 (im on a netbook)

I made sure i put the extra dll in my system32 folder, the library is in the right place - i set a blank sketch with 1 line - import JMyron.*; and it ran fine just giving me a blank grey box so the library is in the right place.

Any help appreciated
