Getting LibSVM to work with Weka on Mac

Somehow, the only way to use LibSVM with Weka is by using the bash command-line.

Step 1: Get Weka.

Assume the bleeding edge version 3.7.0. Unzip and put in /Applications folder.

Step 2: Get LibSVM.
a. Iowa State site (http://www.cs.iastate.edu/~yasser/wlsvm/wlsvm.zip):
If you use Safari to download, it will be unzipped in the Downloads directory. The files you need are ~/Downloads/WLSVM/lib/wlsvm.jar and /Downloads/WLSVM/lib/libsvm.jar
b. Taiwan site(http://www.csie.ntu.edu.tw/~cjlin/libsvm/libsvm-2.89.zip):
Using Safari to download, the file you need is ~/Downloads/libsvm-2.89/java/libsvm.jar

Step 3: Open Terminal and copy to Weka.app. Assume you have privileges to write into Weka.app.
a. Iowa State version:
$ cp ~/Downloads/WLSVM/lib/*.jar /Applications/Weka/weka-3-7-0.app/Contents/Resources/Java
b. Taiwan version:
$ cp ~/Downloads/libsvm-2.89/java/libsvm.jar /Applications/Weka/weka-3-7-0.app/Contents/Resources/Java

Step 4: Set CLASSPATH

$ export CLASSPATH=$CLASSPATH:/Applications/Weka/weka-3-7-0.app/Contents/Resources/Java/

Step 5:Run Weka from Terminal!

$ java -classpath $CLASSPATH:weka.jar:libsvm.jar weka.gui.GUIChooser &

Conclusion: Bash sucks less!
