Compilers in nixpkgs have caught up and major distros should also have recent enough compilers. It would be nice to have newer features like more full featured ranges and deducing this.

# Prerequisites
|
||
|
||
- 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++23.
|
||
|
||
- `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 (`bdw-gc`)](http://www.hboehm.info/gc/) to reduce
|
||
the evaluator’s 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. This
|
||
is an optional dependency and can be disabled passing a
|
||
`--disable-seccomp-sandboxing` option to the `configure` script (Not
|
||
recommended unless your system doesn't support `libseccomp`). 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-unit-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.
