You can download the latest version from here:
https://github.com/JohnLangford/vowpal_wabbit/archives/master
Alternatively, the very latest version is available here:
git clone git://github.com/JohnLangford/vowpal_wabbit.git
You should be able to build it on posix systems with:
make
(make test)
make install
If 'make' fails, you are probably missing the dependency on boost program options. Intall it and try again.
Be sure to read the wiki: https://github.com/JohnLangford/vowpal_wabbit/wiki
for the tutorial, command line options, etc.
The 'cluster' directory has it's own documentation for cluster
parallel use, and the examples at the end of test/Runtests give some
example flags.
