Build Environment

Use Nix as Reproducible Development Environment​

The dependencies for a dynamic build can be fetched by running nix develop from the topmost directory in the source tree.

The direnv tool is able to automate this process, create an .envrc with the content:

use flake

and it will automatically add the dependencies to your shell environment when you move into the source directory.

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:

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 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
note

This build environment is currently only tested on Linux.

Static Builds​

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

nix develop .#tenzir-static

The CMake presets for that mode are:

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