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 executable 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 doesn'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 arguments, 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.
