			=== Flakes ===

			A Tup rule must not use a flake that resides in the same tup project as the rule because the nix command can aggressively access files in the vicinity of flake.nix. The flake should be external to the tup project or it can be stored within the same repository but only on a different branch, which would then then be registered in the local nix flake registry.

			Another method that minimizes changes to PATH is to create symlinks to tools with Tup:

			<syntaxhighlight lang="tup">
			# Tuprules.tup - export a bang-rule that calls the Dhall interpreter
			DHALL_LINK = $(TUP_CWD)/dhall
			!dhall = \| $(DHALL_LINK) \|> $(DHALL_LINK)/bin/dhall \|>
			</syntaxhighlight>

			<syntaxhighlight lang="tup">
			# Tupfile - build a symlink to the nixpkgs#dhall package
			include_rules
			: \|> nix build nixpkgs#dhall --out-link %o \|> $(DHALL_LINK)
			</syntaxhighlight>

			=== tup rebuilds too often ===

			When using <code>updater.full_dep</code>, tup rebuilds the full project every time you reboot due to
			mtime changes in /run/current-system.

			The solution is to always use tup via <code>nix-shell --pure</code> so that /run/current-system is not in PATH

			There is no real solution to this other than 1. patching tup to use setuid fusermount 2. (maybe) setting tup as setuid.

imported>Sheenobu: Add page about using Tup.

Add page about using Tup.

New page

From the tup manual: "Tup is a file-based build system".

== Known Issues ==

=== mount does not unmount ===

Tup can either not find fusermount OR the fusermount that
tup finds is not setuid. Github issue: (107516)[https://github.com/NixOS/nixpkgs/issues/107516].

=== pkg-config can not find my packages ===

When using nix-shell, pkg-config, and tup; pkg-config calls via tup
do not find any packages.

You must add export lines to your tupfile that correspond to the variables set by NixOS pkg-config:

export PKG_CONFIG_PATH
export PKG_CONFIG_PATH_FOR_TARGET
export PKG_CONFIG_FOR_TARGET

You also have to export NIX_PKG_CONFIG* variables, which can change based on platform:

export NIX_PKG_CONFIG_WRAPPER_TARGET_TARGET_x86_64_unknown_linux_gnu

You can verify this by adding <code>: |> pkg-config --list-all > %o |> pkg-list.txt</code> into your Tupfile and seeing which libraries are available via pkg-config.
