libsvm and liblinear is unavailable

[C6H5NO2]

Binary package hint: weka

libsvm is a very important tool for machine learning and it is listed in weka as the classifier "LibSVM". But it reports error if we select LibSVM in the default Ubuntu version of weka. In Ubuntu 9.10, there is a package named "libsvm2-java". After installing it and modifying the line "find_jars weka.jar" by "find_jars weka.jar libsvm.jar", libsvm can run very well.

Another classifier in weka, "LibLINEAR", will report similar error. A open sourced jar file of liblinear can be got at "http://www.bwaldvogel.de/liblinear-java/".

Well, could the support of libsvm and liblinear be added in weka by default?

My impression, is that, because of legal issues this is not done yet, which may imply that it will not be made in the future either.

However, what can be corrected is the fact that when one installs libsvm2-java, all the setup should be done automatically, i.e., Ubuntu should be smart enough to detect where are the right path of weka.jar.

Status changed to 'Confirmed' because the bug affects multiple users.

I agree with Cesar. One note though; Weka's developmental trunk (3.7.x) has its own package manager, making the installation of LibSVM and LibLINEAR a piece of cake. I have no idea though when or if 3.7.x will become the official release.
