carnivore library, unsatisfiedlinkerror

in Contributed Library Questions • 1 year ago

I'm recently playing with the carnivore library for processing. But I'm getting a unsatisfiedlinkerror for just running the example sketch. Here's all I got from the console.

[org.rsg.carnivore.Log] setDebug: true

I found a post where exactly the same issue happened to somebody else, but still no answer for this.

Thanks.

Well, I can't add anything to what I answered at the time: do you have the needed shared libraries? Is Wireshark working on your computer?

I'm running on a mac osx lion. According to the instruction of carnivore, I suppose WinPCap is only needed on a win machine. Wireshark is also for windows right?

I ran the script required for mac " sudo chmod 777 /dev/bpf* ", and errors above is what i got. I don't have a window machine to test at the moment. Is there any equivalent thing I should install to get carnivore working on a mac?

Wireshark is built upon GTK+, so it should be pretty portable.
Which is confirmed by a brief look at their home page...

I should have read more carefully about Wireshark

I have installed it, and it seems like to be capturing some traffic. With Wireshark running in the background, the processing sketch is still giving me the error.

As shown in the image.

I see jpcap is mentioned in the stack trace. It is rather old library, the release note of the latest release mention Mac OS X support, implying it was quite "young", perhaps it is buggy.
Or not compatible with your version. Do you use a 64bit Java? Try with a 32bit one. Do you use OpenJDK? Try with Oracle or Apple versions. Etc.

attemp 1.

I checked the jpcap link you gave, followed the instruction to install it. Which is:

Both Java and libpcap are preinstalled on Mac OS X.
If any of them is missing you should be able to install them from the Mac OS X install DVD.
Download and install Xcode.
The default installation of Xcode should provide you with the toolchain required for compiling Jpcap.
Download and extract Jpcap source build.
Go to '[Jpcap extracted directory]/src/c' directory.
Run 'make'.
Copy 'libjpcap.jnilib' to '/Library/Java/Extensions/' directory.
Copy '[Jpcap extracted directory]/lib/jpcap.jar' to '/Library/Java/Extensions/'
Or, place 'jpcap.jar' to any directory and include it to your CLASSPATH.

I do have xcode 4.1 installed on my machine, and put the files generated/downloaded to "Extensions" folder. But it still gives me same error.

attempt 2.

I have no idea about OpenJDK, but downloaded and installed a OpenJDK 7 from here.

It didn't end up making any difference in terms of the error processing spits out.

PS:

Not sure if this is useful, but all the error messages p5 spits out, comes after I typed the script " sudo chmod 777 /dev/bpf* " in terminal. Before doing that, p5 doesn't give error, but tells me to do so as instructed in carnivore's example code #2.

attempt 3.

I will try to install java 32bit version tomorrow.

btw, I had the same problem... The fix was to just run processing in 32-bit mode instead of 64-bit mode. =)

would you spare a copy of your "" libjpcap.jnilib "" file.. I really need it to install TubeMaster++ on my macBook running Lion 10.7.4 please.. and if you don't mind can you tell me how to compile jpcap using xCode (i have never used it before) sorry for my ignorance. Your help will be greatly appreciated.

another SOLUTION:

I started out with this sketch(carnivore) and had no problems. Then all of a sudden, it stopped working. I searched the forums low and high with no real solution. I don't know if this will fix everyone's problem but, it is angle that hasn't been talked about...

First off, what version of processing are people using that they are unable to properly run the sketch?

I realized that the sketch stopped working for me whenever I updated Processing. Only when I compiled the code using the stable version of Processing (1.5) does the carnivore library work. I realized that I had saved out the code in a later version and apparently this is what was causing the complications. I deleted all updated versions of the program and re-installed the carnivore examples that I was using -- and presto! Everything is fully functional.

By the way this was the error that I was getting: Can't load IA 32-bit .dll on a AMD 64-bit platform

hello people! I am studying carnivore and I found a problem when running the examples:
http://r-s-g.org/carnivore/installation.html

The error I get is:

UnsatisfiedLinkError: net.sourceforge.jpcap.capture.PacketCapture.open (ILjava / lang / String; IZI) V

Working on Mac OS X, and run Version Processing 2.0b.8 . and also run the terminal: sudo chmod 777 / dev / bpf *

Can anyone give me a help?
Thank you very much and sorry for my English
