Bison is a free implementation of yacc.

2.11.1. UNIX: bison

Bison is available for most of the UNIX-like platforms and as the bison package from the Cygwin setup.

If GNU Bison isn't already installed and also not available as a package for your platform, you can get it at: http://www.gnu.org/software/bison/bison.html.

After correct installation, typing inside the bash:

$ bison --version

should result in something like:

bison (GNU Bison) 1.875b
