Unsatisfied link error
04/14/09 at 15:21:40

Hi

I'm new to carnivore but really excited about the possibilities. I'm using a macbook pro with leopard 10.5 and java 1.6. When I try to run the example sketch (after performing the chmod command) I'm getting this error every time...

[org.rsg.carnivore.CarnivoreP5] starting carnivore core
[org.rsg.carnivore.Core] starting Carnivore core...
[org.rsg.carnivore.net.Devices] Found network devices: {en1=AirPort}

I cannot seem to find any explanation anywhere and it would be really great if someone could help!

Thanks in advance for any help you guys can give.

if i remember, UnsatisfiedLinkErrors happen when when you don't have the right classes or libraries in place. did you follow the installation instructions exactly? perhaps try to install the carnivore library again. make sure you have "libjpcap-i386.jnilib" in the Processing/libraries/carnivore/library folder

(are you sure about having java 1.6? i thought OSX was still only supporting 1.5? -- in any case that's what carnivore is compiled for, so if you do have 1.6, that might be causing problems too, not sure.)

OSX Leopard is compatible with 1.6 you just have to force it to be used. Apple don't have it running out of the box for some reason.

Hi,

I am having a similar error. I am also on OS X 10.6 but I am using Java 1.5 so I don't think that's the problem.

If I run my app from Processing, everything works properly.
If I export the app as an application and run it on my machine, everything works properly.
If I run the exported app on a friend's computer (who does not have Processing or Carnivore installed), I get the "Unsatisfied link error" below:
Code:

Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: net.sourceforge.jpcap.capture.PacketCapture.open(ILjava/lang/String;IZI)V

When I check the Package Contents of my app, I have "carnivore.jar", "libjpcap-i386.jnilib", and "libjpcap-ppc.jnilib" in the "Java" folder.

Any ideas?

Thanks,
-Elie

yeah i think that error means it can't find the native libraries.

is your friend's machine a PowerPC mac by any chance (and your machine an Intel mac), or vice versa?

is there anything else that is different between the two machines that you can tell us to help troubleshoot?

it's also possible that some sort of path is being hard coded into the app when you export it from processing.
