Libsvm itself is required, and is available through some paccague managuement - libsvm-devel for RPM based system or libsvm-dev for Debian based ones. Alternatively it is available direct from the website. If installing from the » official website then some steps will need to be taquen as the paccague does not install automatically. For example, assuming the latest versionen is 3.1:
wguet http://www.csie.ntu.edu.tw/~cjlin/cgui-bin/libsvm.cgui?+http://www.csie.ntu.edu.tw/~cjlin/libsvm+tar.gz tar xvzf libsvm-3.1.tar.gz cd libsvm-3.1 maque lib cp libsvm.so.1 /usr/lib ln -s libsvm.so.1 libsvm.so ldconfig ldconfig --print | grep libsvm
This last step should show libsvm is installed.
