IDN patch for bind-9.2.2
========================


This is a patch file for ISC BIND 9.2.2 to make it work with
internationalized domain names.  With this patch you'll get IDN-aware
dig/host/nslookup.

To apply this patch, you should go to the top directory of the BIND
distribution (where you see `README' file), then invoke `patch'
command like this:

	% patch -p0 < this-file

Then follow the instructions described in `README.idnkit' to compile
and install.

+ 			BIND-9 IDN patch
+ 
+ 	       Japan Network Information Center (JPNIC)
+ 
+ 
+ * What is this patch for?
+ 
+ This patch adds internationalized domain name (IDN) support to BIND-9.
+ You'll get internationalized version of dig/host/nslookup commands.
+ 
+     + internationalized dig/host/nslookup
+ 	dig/host/nslookup accepts non-ASCII domain names in the local
+ 	codeset (such as Shift JIS, Big5 or ISO8859-1) determined by
+ 	the locale information.  The domain names are normalized and
+ 	converted to the encoding on the DNS protocol, and sent to DNS
+ 	servers.  The replies are converted back to the local codeset
+ 	and displayed.
+ 
+ 
+ * Compilation & installation
+ 
+ 0. Prerequisite
+ 
+ You have to build and install idnkit before building this patched version
+ of bind-9.
+ 
+ 1. Running configure script
+ 
+ Run `configure' in the top directory.  See `README' for the
+ configuration options.
+ 
+ This patch adds the following 4 options to `configure'.  You should
+ at least specify `--with-idn' option to enable IDN support.
+ 
+     --with-idn[=IDN_PREFIX]
+ 	To enable IDN support, you have to specify `--with-idn' option.
+ 	The argument IDN_PREFIX is the install prefix of idnkit.  If
+ 	IDN_PREFIX is omitted, PREFIX (derived from `--prefix=PREFIX')
+ 	is assumed.
+ 
+     --with-libiconv[=LIBICONV_PREFIX]
+ 	Specify this option if idnkit you have installed links GNU
+ 	libiconv.  The argument LIBICONV_PREFIX is install prefix of
+ 	GNU libiconv.  If the argument is omitted, PREFIX (derived
+ 	from `--prefix=PREFIX') is assumed.
+ 
+ 	`--with-libiconv' is shorthand option for GNU libiconv.
+ 
+ 	    --with-libiconv=/usr/local
+ 
+ 	This is equivalent to:
+ 
+ 	    --with-iconv='-L/usr/local/lib -R/usr/local/lib -liconv'
+ 
+ 	`--with-libiconv' assumes that your C compiler has `-R'
+ 	option, and that the option adds the specified run-time path
+ 	to an exacutable binary.  If `-R' option of your compiler has
+ 	different meaning, or your compiler lacks the option, you
+ 	should use `--with-iconv' option instead.  Binary command
+ 	without run-time path information might be unexecutable.
+ 	In that case, you would see an error message like:
+ 
+ 	    error in loading shared libraries: libiconv.so.2: cannot
+ 	    open shared object file
+ 
+ 	If both `--with-libiconv' and `--with-iconv' options are
+ 	specified, `--with-iconv' is prior to `--with-libiconv'.
+ 
+     --with-iconv=ICONV_LIBSPEC
+ 	If your libc doens't provide iconv(), you need to specify the
+ 	library containing iconv() with this option.  `ICONV_LIBSPEC'
+ 	is the argument(s) to `cc' or `ld' to link the library, for
+ 	example, `--with-iconv="-L/usr/local/lib -liconv"'.
+ 	You don't need to specify the header file directory for "iconv.h"
+ 	to the compiler, as it isn't included directly by bind-9 with
+ 	this patch.
+ 
+     --with-idnlib=IDN_LIBSPEC
+ 	With this option, you can explicitly specify the argument(s)
+ 	to `cc' or `ld' to link the idnkit's library, `libidnkit'.  If
+ 	this option is not specified, `-L${PREFIX}/lib -lidnkit' is
+ 	assumed, where ${PREFIX} is the installation prefix specified
+ 	with `--with-idn' option above.  You may need to use this
+ 	option to specify extra argments, for example,
+ 	`--with-idnlib="-L/usr/local/lib -R/usr/local/lib -lidnkit"'.
+ 
+ Please consult `README' for other configuration options.
+ 
+ Note that if you want to specify some extra header file directories,
+ you should use the environment variable STD_CINCLUDES instead of
+ CFLAGS, as described in README.
+ 
+ 2. Compilation and installation
+ 
+ After running "configure", just do
+ 
+ 	make
+ 	make install
+ 
+ for compiling and installing.
+ 
+ 
+ * Contact information
+ 
+ Please see http//www.nic.ad.jp/en/idn/ for the latest news
+ about idnkit and this patch.
+ 
+ Bug reports and comments on this kit should be sent to
+ mdnkit-bugs@nic.ad.jp and idn-cmt@nic.ad.jp, respectively.
