Build Environment

Use Nix as reproducible development environment

We use Nix for reproducible Tenzir Node builds.

Fetch the dependencies for a dynamic build by running nix develop from the topmost directory in the tenzir/tenzir source tree.

You can automatically add the dependencies to your shell environment when you cd into the source directory via direnv. Create an .envrc with the content:

use flake

If you want to silence the messages about binary caches you can use a variation of .envrc that invokes nix with a lower verbosity setting:

Terminal window
use_flake2() {
  watch_file flake.nix
  watch_file flake.lock
  mkdir -p "$(direnv_layout_dir)"
  eval "$(nix --quiet --quiet print-dev-env --profile "$(direnv_layout_dir)/flake-profile" "$@")"
}


use_flake2

The tenzir/tenzir repository comes with a set of CMake configure and build presets that can be used in this environment:

  • nix-clang-debug
  • nix-clang-redeb
  • nix-clang-release
  • nix-gcc-debug
  • nix-gcc-redeb
  • nix-gcc-release

Compile static binaries

Static binaries require a that the dependencies were built in static mode as well. That means we need to use a different environment; you can enter it with:

Terminal window
nix develop .#tenzir-static

The CMake presets for that mode are:

  • nix-gcc-static-debug
  • nix-gcc-static-redeb
  • nix-gcc-static-release
