README for GNU DIFF This directory contains the GNU diff, diff3, sdiff, and cmp utilities. Their features are a superset of the Unix features and they are significantly faster. Please see the file COPYING for copying conditions. Please see the file doc/version.texi for version information. Please see the file doc/diffutils.texi (or doc/diffutils.info) for documentation that can be printed with TeX, or read with the 'info' program or with Emacs's 'M-x info'. Brief man pages are in man/*, but they are no substitute for the documentation. Please see the file ABOUT-NLS for notes about translations. Please see the file INSTALL for generic compilation and installation instructions. Briefly, you can run "./configure; make install". The command "./configure --help" lists the supported --enable and --with options. If you have a problem with internationalization, you might be able to work around it as described in ABOUT-NLS by invoking './configure --disable-nls'. Many of the problems arise from dynamic linking issues on non-GNU platforms (e.g. with the iconv library). Such problems tend to be shared by other GNU applications on these platforms, and can usually be fixed by carefully tweaking your non-GNU installation. If you have an older version of libiconv, please upgrade to the latest one; see <ftp://ftp.gnu.org/gnu/libiconv/>. If the problem seems isolated to diffutils, though, please report a bug. This program requires a Standard C compiler (C89 or later). If you have a nonstandard compiler, please install GCC first. If you make changes to the source code, you may need appropriate versions of GNU build tools to regenerate the intermediate files. The following versions were used to generate the intermediate files in this distribution: * Autoconf 2.59 <ftp://ftp.gnu.org/gnu/autoconf/autoconf-2.59.tar.gz> * Automake 1.8.3 <ftp://ftp.gnu.org/gnu/automake/automake-1.8.3.tar.gz> * gettext 0.14.1 <ftp://ftp.gnu.org/gnu/gettext/gettext-0.14.1.tar.gz> * help2man 1.33 <ftp://ftp.gnu.org/gnu/help2man/help2man-1.33.1.tar.gz> * Texinfo 4.7 <ftp://ftp.gnu.org/gnu/texinfo/texinfo-4.7.tar.gz> For any copyright year range specified as YYYY-ZZZZ in this package note that the range specifies every single year in that closed interval.
