This package contains the GIZA++ toolkit and the mkcls tool, originally written by F.J. Och and several other authors. For more information, refer to the README files and the following pages: http://www.fjoch.com/mkcls.html http://www.fjoch.com/GIZA++.html UPDATE 4th April 2015, by Hieu Hoang: Works with most versions of gcc, including really old versions. Doesn't work with recent versions of clang. Why not try using mgiza? It's multi-threaded and kept up to date to work with most compilers https://github.com/moses-smt/mgiza
