Ondřej Surý 440fb3d225 Completely remove BIND 9 Windows support
The Windows support has been completely removed from the source tree
and BIND 9 now no longer supports native compilation on Windows.

We might consider reviewing mingw-w64 port if contributed by external
party, but no development efforts will be put into making BIND 9 compile
and run on Windows again.

Supported platforms

In general, this version of BIND will build and run on any POSIX-compliant system with a C11-compliant C compiler, BSD-style sockets with RFC-compliant IPv6 support, POSIX-compliant threads, the libuv asynchronous I/O library, the OpenSSL cryptography library, and the nghttp2 HTTP/2 library.

The following C11 features are used in BIND 9:

  • Atomic operations support from the compiler is needed, either in the form of builtin operations.

  • Thread Local Storage support from the compiler is needed, either in the form of C11 _Thread_local/thread_local, or the __thread GCC extension.

The C11 variants are preferred.

BIND 9.17 requires a fairly recent version of libuv (at least 1.x). For some of the older systems listed below, you will have to install an updated libuv package from sources such as EPEL, PPA, or other native sources for updated packages. The other option is to build and install libuv from source.

Certain optional BIND features have additional library dependencies. These include libxml2 and libjson-c for statistics, libmaxminddb for geolocation, libfstrm and libprotobuf-c for DNSTAP, and libidn2 for internationalized domain name conversion.

ISC regularly tests BIND on many operating systems and architectures, but lacks the resources to test all of them. Consequently, ISC is only able to offer support on a "best effort" basis for some.

Regularly tested platforms

As of Nov 2020, BIND 9.17 is fully supported and regularly tested on the following systems:

  • Debian 9, 10
  • Ubuntu LTS 18.04, 20.04
  • Fedora 34
  • Red Hat Enterprise Linux / CentOS 7, 8
  • FreeBSD 11.4, 12.2, 13.0
  • OpenBSD 6.9
  • Alpine Linux 3.13

The amd64, i386, armhf and arm64 CPU architectures are all fully supported.

Best effort

The following are platforms on which BIND is known to build and run. ISC makes every effort to fix bugs on these platforms, but may be unable to do so quickly due to lack of hardware, less familiarity on the part of engineering staff, and other constraints. None of these are tested regularly by ISC.

  • macOS 10.12+
  • Solaris 11
  • NetBSD
  • Other Linux distributions still supported by their vendors, such as:
    • Ubuntu 20.10+
    • Gentoo
    • Arch Linux
  • OpenWRT/LEDE 17.01+
  • Other CPU architectures (mips, mipsel, sparc, ...)

Community maintained

These systems may not all have the required dependencies for building BIND easily available, although it will be possible in many cases to compile those directly from source. The community and interested parties may wish to help with maintenance, and we welcome patch contributions, although we cannot guarantee that we will accept them. All contributions will be assessed against the risk of adverse effect on officially supported platforms.

  • Platforms past or close to their respective EOL dates, such as:
    • Ubuntu 14.04, 16.04 (Ubuntu ESM releases are not supported)
    • CentOS 6
    • Debian Jessie
    • FreeBSD 10.x

Unsupported platforms

These are platforms on which BIND 9.17 is known not to build or run:

  • Platforms without at least OpenSSL 1.0.2
  • Windows
  • Solaris 10 and older
  • Platforms that don't support IPv6 Advanced Socket API (RFC 3542)
  • Platforms that don't support atomic operations (via compiler or library)
  • Linux without NPTL (Native POSIX Thread Library)
  • Platforms on which libuv cannot be compiled
