README: This is GNU Awk 4.1.4. It is upwardly compatible with Brian Kernighan's version of Unix awk. It is almost completely compliant with the 2008 POSIX 1003.1 standard for awk. (See the note below about POSIX.) This is a bug-fix release. See NEWS and ChangeLog for details. Work to be done is described briefly in the TODO file, which is available only in the 'master' branch in the Git repo. Changes in this version are summarized in the NEWS file. Read the file POSIX.STD for a discussion of issues where the standard says one thing but gawk does something different. To format the documentation with TeX, use at least version 2016-02-05.07 of texinfo.tex. There is a usable copy of texinfo.tex in the doc directory. You should also use at least version 6.1 of texindex and of makeinfo from the texinfo-6.1 distribution. INSTALLATION: Check whether there is a system-specific README file for your system under the `README_d' directory. If there's something there that you should have read and didn't, and you bug me about it, I'm going to yell at you. See the file INSTALL for installation instructions. If you have neither bison nor yacc, use the awkgram.c file here. It was generated with bison, and has no proprietary code in it. (Note that modifying awkgram.y without bison or yacc will be difficult, at best. You might want to get a copy of bison from the FSF too.) If you have an MS-DOS, MS-Windows, or OS/2 system, use the stuff in the `pc' directory. Similarly, there is a separate directory for VMS. Appendix B of ``GAWK: Effective Awk Programming'' discusses configuration in detail. The configuration process is based on GNU Autoconf and Automake. After successful compilation, do `make check' to run the test suite. There should be no output from the `cmp' invocations except in the cases where there are small differences in floating point values, and possibly in the case of strftime. There may be differences based on installed (or not installed) locales and the quality of multibyte character support on your system. Several of the tests ignore errors on purpose; those are not a problem. If there are other differences, please investigate and report the problem. PRINTING THE MANUAL The `doc' directory contains a recent version of texinfo.tex, which will be necessary for printing the manual. Use `make dvi' to get a DVI file from the manual. In the `doc' directory, use `make postscript' to get PostScript versions of the manual, the man page, and the reference card. Use `make pdf' to get PDF versions of the manuals, the man page and the reference card. BUG REPORTS AND FIXES (Un*x systems): Please coordinate changes through Arnold Robbins. In particular, see the section in the manual on reporting bugs. Note that comp.lang.awk is about the worst place to post a gawk bug report. Please, use the mechanisms outlined in the manual. Email should be sent to bug-gawk@gnu.org. This is a separate mailing list at GNU Central. The advantage to using this address is that bug reports are archived at GNU Central.
