Bison is a parser generator used for some of Wireshark’s file format support.
Bison is available for most UNIX and UNIX-like platforms. See the next section for native Windows options.
If GNU Bison isn’t already installed or available as a package for your platform you can get it at: http://www.gnu.org/software/bison/bison.html.
After correct installation running the following
$ bison --version
should result in something like:
bison (GNU Bison) 2.3 Written by Robert Corbett and Richard Stallman. Copyright (C) 2006 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
Your version string may vary.
A native Windows version of bison is available in the winflexbison Chocolatey package. Note that the executable is named win_bison.
Native packages are available from other sources such as GnuWin. They aren’t officially supported but should work.
