I have just released an SVM tool called DCASVM. DCASVM is an implementation of the Dual Coordinate Ascent/Descent SVM algorithm.
It is a bit faster than Liblinear.
It is tested using gcc-4.7.2 on Fedora 13. It should work on any C++ environment except the elapsed time measuring part. (You can comment it out if compile errors occur.)
You can download the tgz archive from:

Any comments are welcome.
