3 [[https://www.gnu.org/software/guix/][GNU Guix]] (IPA: /ɡiːks/) is a purely functional package manager, and
4 associated free software distribution, for the [[https://www.gnu.org/gnu/gnu.html][GNU system]]. In addition
5 to standard package management features, Guix supports transactional
6 upgrades and roll-backs, unprivileged package management, per-user
7 profiles, and garbage collection.
9 It provides [[https://www.gnu.org/software/guile/][Guile]] Scheme APIs, including a high-level embedded
10 domain-specific languages (EDSLs) to describe how packages are to be

29 - [[http://www.zlib.net/][zlib]]
30 - [[https://savannah.nongnu.org/projects/guile-json/][Guile-JSON]]

34 - [[https://gnupg.org/][GNU libgcrypt]]
35 - [[https://sqlite.org/][SQLite 3]]
36 - [[https://gcc.gnu.org][GCC's g++]]
37 - optionally [[http://www.bzip.org][libbz2]]
39 When `--disable-daemon' was passed, you instead need the following:

45 See the manual for the installation instructions, either by running
47 info -f doc/guix.info "Installation"
49 or by checking the [[https://www.gnu.org/software/guix/manual/guix.html#Installation][web copy of the manual]].
51 For information on installation from a Git checkout, please see the section
52 "Building from Git" in the manual.
54 * Installing Guix from Guix
56 You can re-build and re-install Guix using a system that already runs Guix.
59 - Start a shell with the development environment for Guix:
63 - Re-run the 'configure' script passing it the option
64 '--localstatedir=/somewhere', where '/somewhere' is the 'localstatedir'
65 value of the currently installed Guix (failing to do that would lead the
66 new Guix to consider the store to be empty!).
68 - Run "make", "make check", and "make install".
72 Guix does the high-level preparation of a /derivation/. A derivation is
73 the promise of a build; it is stored as a text file under
74 =/gnu/store/xxx.drv=. The (guix derivations) module provides the
75 `derivation' primitive, as well as higher-level wrappers such as
76 `build-expression->derivation'.
78 Guix does remote procedure calls (RPCs) to the Guix or Nix daemon (the
79 =guix-daemon= or =nix-daemon= command), which in turn performs builds
80 and accesses to the Nix store on its behalf. The RPCs are implemented
81 in the (guix store) module.
83 * Installing Guix as non-root
85 The Guix daemon allows software builds to be performed under alternate
86 user accounts, which are normally created specifically for this
87 purpose. For instance, you may have a pool of accounts in the
88 =guixbuild= group, and then you can instruct =guix-daemon= to use them
91 $ guix-daemon --build-users-group=guixbuild
93 However, unless it is run as root, =guix-daemon= cannot switch users.
94 In that case, it falls back to using a setuid-root helper program call
95 =nix-setuid-helper=. That program is not setuid-root by default when
96 you install it; instead you should run a command along these lines
97 (assuming Guix is installed under /usr/local):
99 # chown root.root /usr/local/libexec/nix-setuid-helper
100 # chmod 4755 /usr/local/libexec/nix-setuid-helper

114 GNU Guix is based on [[https://nixos.org/nix/][the Nix package manager]]. It implements the same
115 package deployment paradigm, and in fact it reuses some of its code.
116 Yet, different engineering decisions were made for Guix, as described
119 Nix is really two things: a package build tool, implemented by a library
120 and daemon, and a special-purpose programming language. GNU Guix relies
121 on the former, but uses Scheme as a replacement for the latter.
123 Using Scheme instead of a specific language allows us to get all the
124 features and tooling that come with Guile (compiler, debugger, REPL,
125 Unicode, libraries, etc.) And it means that we have a general-purpose
126 language, on top of which we can have embedded domain-specific languages
127 (EDSLs), such as the one used to define packages. This broadens what
128 can be done in package recipes themselves, and what can be done around them.
130 Technically, Guix makes remote procedure calls to the ‘nix-worker’
131 daemon to perform operations on the store. At the lowest level, Nix
132 “derivations” represent promises of a build, stored in ‘.drv’ files in
133 the store. Guix produces such derivations, which are then interpreted
134 by the daemon to perform the build. Thus, Guix derivations can use
135 derivations produced by Nix (and vice versa).
137 With Nix and the [[https://nixos.org/nixpkgs][Nixpkgs]] distribution, package composition happens at
138 the Nix language level, but builders are usually written in Bash.
139 Conversely, Guix encourages the use of Scheme for both package
140 composition and builders. Likewise, the core functionality of Nix is
141 written in C++ and Perl; Guix relies on some of the original C++ code,
142 but exposes all the API as Scheme.
146 - [[https://nixos.org][Nix, Nixpkgs, and NixOS]], functional package manager and associated
147 software distribution, are the inspiration of Guix
148 - [[https://www.gnu.org/software/stow/][GNU Stow]] builds around the idea of one directory per prefix, and a
149 symlink tree to create user environments
150 - [[https://www.pvv.ntnu.no/~arnej/store/storedoc_6.html][STORE]] shares the same idea
151 - [[https://live.gnome.org/OSTree/][GNOME's OSTree]] allows bootable system images to be built from a
152 specified set of packages
153 - The [[https://www.gnu.org/s/gsrc/][GNU Source Release Collection]] (GSRC) is a user-land software
154 distribution; unlike Guix, it relies on core tools available on the
