+Building BIND 9
+---------------
+
+To build on a Unix or Linux system, use:
+
+::
+
+    $ autoreconf -fi ### (only if building from the git repository)
+    $ ./configure
+    $ make
+
+Several environment variables affect compilation, and they can be set
+before running ``configure``. The most significant ones are:
+
++--------------------+-------------------------------------------------+
+| Variable           | Description                                     |
++====================+=================================================+
+| ``CC``             | The C compiler to use. ``configure`` tries to   |
+|                    | figure out the right one for supported systems. |
++--------------------+-------------------------------------------------+
+| ``CFLAGS``         | The C compiler flags. Defaults to include -g    |
+|                    | and/or -O2 as supported by the compiler. Please |
+|                    | include ``-g`` if ``CFLAGS`` needs to be set.   |
++--------------------+-------------------------------------------------+
+| ``LDFLAGS``        | The linker flags. Defaults to an empty string.  |
++--------------------+-------------------------------------------------+
+
+Additional environment variables affecting the build are listed at the
+end of the ``configure`` help text, which can be obtained by running the
+command:
+
+::
+
+    $ ./configure --help
+
+If using Emacs, the ``make tags`` command may be helpful.
+
+.. _build_dependencies:
+
+Required Libraries
+~~~~~~~~~~~~~~~~~~
+
+To build BIND 9, the following packages must be installed:
+
+- ``libcrypto``, ``libssl``
+- ``libuv``
+- ``perl``
+- ``pkg-config`` / ``pkgconfig`` / ``pkgconf``
+
+BIND 9.18 requires ``libuv`` 1.0.0 or higher, using ``libuv`` >= 1.40.0
+is recommended. Compiling or running with ``libuv`` 1.35.0 or 1.36.0 is
+not supported, as this could lead to an assertion failure in the UDP
+receive code. On older systems, an updated ``libuv`` package needs to be
+installed from sources such as EPEL, PPA, or other native sources. The
+other option is to build and install ``libuv`` from source.
+
+OpenSSL 1.0.2e or newer is required. If the OpenSSL library is installed
+in a nonstandard location, specify the prefix using
+``--with-openssl=<PREFIX>`` on the ``configure`` command line. To use a
+PKCS#11 hardware service module for cryptographic operations,
+``engine_pkcs11`` from the OpenSC project must be compiled and used.
+
+To build BIND from the git repository, the following tools must also be
+installed:
+
+- ``autoconf`` (includes ``autoreconf``)
+- ``automake``
+- ``libtool``
+
+Optional Features
+~~~~~~~~~~~~~~~~~
+
+To see a full list of configuration options, run ``configure --help``.
+
+To improve performance, use of the ``jemalloc`` library
+(http://jemalloc.net/) is strongly recommended.
+
+To support :rfc:`DNS over HTTPS (DoH) <8484>`, the server must be linked
+with ``libnghttp2`` (https://nghttp2.org/). If the library is
+unavailable, ``--disable-doh`` can be used to disable DoH support.
+
+To support the HTTP statistics channel, the server must be linked with
+at least one of the following libraries: ``libxml2``
+(http://xmlsoft.org) or ``json-c`` (https://github.com/json-c/json-c).
+If these are installed at a nonstandard location, then:
+
+- for ``libxml2``, specify the prefix using ``--with-libxml2=/prefix``,
+- for ``json-c``, adjust ``PKG_CONFIG_PATH``.
+
+To support compression on the HTTP statistics channel, the server must
+be linked against ``zlib`` (https://zlib.net/). If this is installed in
+a nonstandard location, specify the prefix using
+``--with-zlib=/prefix``.
+
+To support storing configuration data for runtime-added zones in an LMDB
+database, the server must be linked with ``liblmdb``
+(https://github.com/LMDB/lmdb). If this is installed in a nonstandard
+location, specify the prefix using ``--with-lmdb=/prefix``.
+
+To support MaxMind GeoIP2 location-based ACLs, the server must be linked
+with ``libmaxminddb`` (https://maxmind.github.io/libmaxminddb/). This is
+turned on by default if the library is found; if the library is
+installed in a nonstandard location, specify the prefix using
+``--with-maxminddb=/prefix``. GeoIP2 support can be switched off with
+``--disable-geoip``.
+
+For DNSTAP packet logging, ``libfstrm``
+(https://github.com/farsightsec/fstrm) and ``libprotobuf-c``
+(https://developers.google.com/protocol-buffers) must be installed, and
+BIND must be configured with ``--enable-dnstap``.
+
+To support internationalized domain names in :iscman:`dig`, ``libidn2``
+(https://www.gnu.org/software/libidn/#libidn2) must be installed. If the
+library is installed in a nonstandard location, specify the prefix using
+``--with-libidn2=/prefix`` or adjust ``PKG_CONFIG_PATH``.
+
+For line editing in :iscman:`nsupdate` and :iscman:`nslookup`, either the
+``readline`` (https://tiswww.case.edu/php/chet/readline/rltop.html) or
+the ``libedit`` library (https://www.thrysoee.dk/editline/) must be
+installed. If these are installed at a nonstandard location, adjust
+``PKG_CONFIG_PATH``. ``readline`` is used by default, and ``libedit``
+can be explicitly requested using ``--with-readline=libedit``.
+
+Certain compiled-in constants and default settings can be decreased to
+values better suited to small machines, e.g. OpenWRT boxes, by
+specifying ``--with-tuning=small`` on the ``configure`` command line.
+This decreases memory usage by using smaller structures, but degrades
+performance.
+
+On Linux, process capabilities are managed in user space using the
+``libcap`` library
+(https://git.kernel.org/pub/scm/libs/libcap/libcap.git/), which can be
+installed on most Linux systems via the ``libcap-dev`` or
+``libcap-devel`` package. Process capability support can also be
+disabled by configuring with ``--disable-linux-caps``.
+
+On some platforms it is necessary to explicitly request large file
+support to handle files bigger than 2GB. This can be done by using
+``--enable-largefile`` on the ``configure`` command line.
+
+Support for the “fixed” RRset-order option can be enabled or disabled by
+specifying ``--enable-fixed-rrset`` or ``--disable-fixed-rrset`` on the
+``configure`` command line. By default, fixed RRset-order is disabled to
+reduce memory footprint.
+
+The ``--enable-querytrace`` option causes :iscman:`named` to log every step
+while processing every query. The ``--enable-singletrace`` option turns
+on the same verbose tracing, but allows an individual query to be
+separately traced by setting its query ID to 0. These options should
+only be enabled when debugging, because they have a significant negative
+impact on query performance.
+
+``make install`` installs :iscman:`named` and the various BIND 9 libraries. By
+default, installation is into /usr/local, but this can be changed with
+the ``--prefix`` option when running ``configure``.
+
+The option ``--sysconfdir`` can be specified to set the directory where
+configuration files such as :iscman:`named.conf` go by default;
+``--localstatedir`` can be used to set the default parent directory of
+``run/named.pid``. ``--sysconfdir`` defaults to ``$prefix/etc`` and
+``--localstatedir`` defaults to ``$prefix/var``.
+
+macOS
+~~~~~
+
+Building on macOS assumes that the “Command Tools for Xcode” are
+installed. These can be downloaded from
+https://developer.apple.com/download/more/ or, if Xcode is already
+installed, simply run ``xcode-select --install``. (Note that an Apple ID
+may be required to access the download page.)
