    This list and lower version bounds are maintained on best-effort basis. When in doubt, check the meson.build files.

    • Meson build system (https://github.com/mesonbuild/meson).

    • Ninja (https://ninja-build.org/).

    • A version of GCC or Clang that supports C++23 (anything newer than Clang 19 or GCC 14 is likely to work).

    • 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 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) to reduce the evaluator’s memory consumption (optional). To enable it, install pkgconfig and the Boehm garbage collector, and pass the option -Dlibexpr:gc=enabled to meson setup.

    • The boost library of version 1.87.0 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 C++ template support in Bison and reentrancy support in Flex.)

    • The libseccomp is used to provide syscall filtering on Linux. This is an optional dependency and can be disabled passing a -Dlibstore:seccomp-sandboxing=disabled option to the meson setup command (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 -Dlibutil:cpuid=disabled option to meson setup script.

    • Unless meson setup build -Dunit-tests=false 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.
