This package contains the GNU Bison parser generator.

• Installation ** Build See the file INSTALL for generic compilation and installation instructions.

Bison requires GNU m4 1.4.6 or later. See:

  ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz

** Internationalization Bison supports two catalogues: one for Bison itself (i.e., for the maintainer-side parser generation), and one for the generated parsers (i.e., for the user-side parser execution). The requirements between both differ: bison needs ngettext, the generated parsers do not. To simplify the build system, neither are installed if ngettext is not supported, even if generated parsers could have been localized. See http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html for more details.

• Questions See the section FAQ in the documentation (doc/bison.info) for frequently asked questions. The documentation is also available in PDF and HTML, provided you have a recent version of Texinfo installed: run "make pdf" or "make html".

If you have questions about using Bison and the documentation does not answer them, please send mail to help-bison@gnu.org.

• Bug reports Please send bug reports to bug-bison@gnu.org. Please include the version number from `bison --version', and a complete, self-contained test case in each bug report.

• Copyright statements For any copyright year range specified as YYYY-ZZZZ in this package, note that the range specifies every single year in that closed interval.
