Instructions for building and installing Moses are online: http://www.statmt.org/moses/?n=Development.GetStarted If you have g++ and Boost installed, and you want the default compilation with most of things you need, then run: ./bjam -j4 Questions should be directed to the mailing list (don't forget to register before sending emails): http://mailman.mit.edu/mailman/listinfo/moses-support https://github.com/moses-smt/mosesdecoder/compare/master...hieu2 Some of the code is not originally part of Moses, but is periodically copied into the source tree from elsewhere: * "bjam-files" is taken from Boost. * "util" and "lm" are taken from KenLM: https://github.com/kpu/kenlm
