<p>FIXME(meson): This section is very wrong with respect to meson and we have commented it out.
We are sorry.
The most current alternative to this section is to read <code>package.nix</code> and see which things are being depended on.</p>

<!--
- GNU Autoconf (<https://www.gnu.org/software/autoconf/>) and the
autoconf-archive macro collection
(<https://www.gnu.org/software/autoconf-archive/>). These are
needed to run the bootstrap script.
- GNU Make.
- Bash Shell. The `./configure` script relies on bashisms, so Bash is
required.
- A version of GCC or Clang that supports C++20.
- `pkg-config` to locate dependencies. If your distribution does not
provide it, you can get it from
<http://www.freedesktop.org/wiki/Software/pkg-config>.
- The OpenSSL library to calculate cryptographic hashes. If your
distribution does not provide it, you can get it from
<https://www.openssl.org>.
- The `libbrotlienc` and `libbrotlidec` libraries to provide
implementation of the Brotli compression algorithm. They are
available for download from the official repository
<https://github.com/google/brotli>.
- cURL and its library. If your distribution does not provide it, you
can get it from <https://curl.haxx.se/>.
- The SQLite embedded database library, version 3.6.19 or higher. If
your distribution does not provide it, please install it from
<http://www.sqlite.org/>.
- The [Boehm garbage collector](http://www.hboehm.info/gc/) to reduce
the evaluators memory consumption (optional). To enable it, install
`pkgconfig` and the Boehm garbage collector, and pass the flag
`--enable-gc` to `configure`.
- The `boost` library of version 1.66.0 or higher. It can be obtained
from the official web site <https://www.boost.org/>.
- The `editline` library of version 1.14.0 or higher. It can be
obtained from the its repository
<https://github.com/troglobit/editline>.
- The `libsodium` library for verifying cryptographic signatures
of contents fetched from binary caches.
It can be obtained from the official web site
<https://libsodium.org>.
- Recent versions of Bison and Flex to build the parser. (This is
because Nix needs GLR support in Bison and reentrancy support in
Flex.) For Bison, you need version 2.6, which can be obtained from
the [GNU FTP server](ftp://alpha.gnu.org/pub/gnu/bison). For Flex,
you need version 2.5.35, which is available on
[SourceForge](http://lex.sourceforge.net/). Slightly older versions
may also work, but ancient versions like the ubiquitous 2.5.4a
won't.
- The `libseccomp` is used to provide syscall filtering on Linux. To get
the library, visit <https://github.com/seccomp/libseccomp>.
- On 64-bit x86 machines only, `libcpuid` library
is used to determine which microarchitecture levels are supported
(e.g., as whether to have `x86_64-v2-linux` among additional system types).
The library is available from its homepage
<http://libcpuid.sourceforge.net>.
This is an optional dependency and can be disabled
by providing a `--disable-cpuid` to the `configure` script.
- Unless `./configure --disable-tests` is specified, GoogleTest (GTest) and
RapidCheck are required, which are available at
<https://google.github.io/googletest/> and
<https://github.com/emil-e/rapidcheck> respectively.
