You can compile the source code simply with any (Sun-compliant) java compiler, or use ant, or an IDE. Check out the Wiki article about Compiling Weka, which contains links to further articles, covering topics about ant and IDEs. See similar questions...

Contributions (or links to them) can be either posted to the Weka mailing list or sent to the Weka maintainer (normally also the admin of the Weka homepage). The conditions for new classifiers (schemes in general) are that, firstly, they have to be published in the proceedings of a renowned conference (e.g., ICML) or as an article of respected journal (e.g., Machine Learning) and, secondly, that they outperform other standard schemes (e.g., J48/C4.5).

All those "cannot find symbol" error messages mean that you do not have the Java servlet JAR file on your compiler's classpath, so it cannot find the servlet class files. The servlet JAR file is normally distributed with your servlet container. For Apache Tomcat it is a file named {CATALINA_HOME}/common/lib/servlet-api.jar. Add this to your compiler classpath as follows. See similar questions...

If you run the classifier weka.classifiers.functions.LibSVM and get the libsvm classes not in CLASSPATH! error message, you are missing the libsvm jar archive in your current classpath. The LibSVM classifier is only a wrapper for using the libsvm classes. Check out the LibSVM article on the Wiki for details about how to use this classifier. See similar questions...

It's not that hard to use Weka classes in your own code, the following articles give a good overview of how to do that: In general, the articles of the source code category. Note: Weka is open-source software under the GNU General Public License, which means that your code has to be licensed under the GPL as well. See similar questions...

Yes, you can. Read the Use Weka with the Microsoft .NET Framework article on the Wiki. There is also a tutorial for IKVM available. See similar questions...

If you need a specific version of Weka, e.g., due to some third-party tools, go Weka's project page (http://sourceforge.net/projects/weka/) on Sourceforge.net (http://sourceforge.net/). In the download section (http://sourceforge.net/project/showfiles.php?group_id=5091) you have access to all the releases ever made. See similar questions...

Reading the Weka Primer article will help you understand the usage of the command line, as well as the How to run Weka schemes from commandline article. See similar questions...

Weka doesn't support internal IDs for instances, one has to use ID attributes. See How do I use ID attributes. See similar questions...

Yes and no. If you're starting from scratch, you might want to consider Jython (http://www.jython.org/), a rewrite of Python (http://www.python.org/) to seamlessly integrate with Java. The drawback is, that you can only use the libraries that Jython implements, not others like NumPy (http://numpy.scipy.org/) or SciPy (http://www.scipy.org/). See similar questions...

brings a new and exciting answer to this question: PAR, a "Cross-Platform Packaging and Deployment tool", originally developed by Autrijus Tang. Before PAR, the only public support for Perl/Tk "compilation" was in the Dr. See similar questions...

Edit the code and remove the arguments to setpgrp. Or upgrade to Expect 5.31 (or later) which adapts automatically. See similar questions...

Check this out: Cobalt Raq2 - Building expect causes Fatal signal 11 in gcc [Kernel 2.0.34 MIPS , Redhat/Cobalt Release 4.0] Seems libieee.a is built oddly and gcc doesn't like it, neither expect nor tcl seem to actully need it, removing -lieee from the makefile allows it to compile, no undefined references, expect passes make test... (Maybe the needed functions are really in libm?) ps: tcl 8.2.1 needs the same fix to compile See similar questions...

REG) See the Kernel HOWTO for some information. Also, there are people at http://www.kernelnewbies.org/ who are usually willing to help. William Stearns) The Buildkernel script walks you through an entire kernel build, including downloading the necessary files, patching the source, building the kernel and modules, installing the lot into lilo, and optionally building pcmcia-cs, cipe, and freeswan code for that kernel.
