* configure.ac: Always show the result of checking for Nixpkgs. Don't warn when Nixpkgs is not found. * Makefile.am (AM_DISTCHECK_CONFIGURE_FLAGS): Remove `--with-nixpkgs' flag. * guix/utils.scm (%nixpkgs-directory): Use either the compile-time or the run-time `NIXPKGS' environment variable. * release.nix (jobs.tarball, jobs.build): Remove `--with-nixpkgs' configure flag. * README: Mark Nixpkgs as optional. * distro/packages/databases.scm, distro/packages/guile.scm, distro/packages/typesetting.scm: Change uses of `nixpkgs-derivation*' to `nixpkgs-derivation', to avoid failing at compile-time.

Guix is Nix[0] from Guile[1]!
|
|
|
|
Concretely, it allows Nix package management to be done entirely in
|
|
Scheme. The goal is to investigate whether Scheme, and in particular
|
|
the ability to define EDSLs, would allow it to fulfill the role of the
|
|
Nix language.

* Hacking
|
|
|
|
Guix currently depends on the following packages:
|
|
|
|
- [[http://gnu.org/software/guile/][GNU Guile 2.0.x]]
|
|
- [[http://nixos.org/nix/][Nix]]
|
|
- [[http://gnupg.org/][GNU libgcrypt]], or [[http://nongnu.org/libchop/][libchop]]
|
|
|
|
Optionally, packages from Nixpkgs may be transparently reused from Guix.
|
|
For this to work, you need to have a checkout of the Nixpkgs repository;
|
|
the `--with-nixpkgs' option allows you to let `configure' know where the
|
|
Nixpkgs checkout is.
|
|
|
|
- [[http://nixos.org/nixpkgs/][Nixpkgs]]
|
|
|
|
When building Guix from a checkout, the following packages are also
|
|
required:
|
|
|
|
- [[http://www.gnu.org/software/autoconf/][GNU Autoconf]]
|
|
- [[http://www.gnu.org/software/automake/][GNU Automake]]
|
|
- [[http://www.gnu.org/software/gettext/][GNU Gettext]]
|
|
|
|
The "autoreconf -vi" command can be used to generate the build system
|
|
infrastructure; it reports an error if an inappropriate version of the
|
|
above packages is being used.
|
|
|
|
* How It Works
|
|
|
|
Guix does the high-level preparation of a /derivation/. A derivation is
|
|
the promise of a build; it is stored as a text file under
|
|
=/nix/store/xxx.drv=. The (guix derivations) module provides the
|
|
`derivation' primitive, as well as higher-level wrappers such as
|
|
`build-expression->derivation'.
|
|
|
|
Guix does remote procedure calls (RPCs) to the Nix daemon (the
|
|
=nix-worker --daemon= command), which in turn performs builds and
|
|
accesses to the Nix store on its behalf. The RPCs are implemented in
|
|
the (guix store) module.
