nixpkgs/pkgs-ng/system/all-packages.fix

# This file evaluates to a function that, when supplied with a system
# identifier, returns the set of all packages provided by the Nix
# Package Collection.  It does this by supplying
# `all-packages-generic.fix' with a standard build environment.
#
# On Linux systems, the standard build environment consists of
# Nix-built instances glibc and the `standard' Unix tools, i.e., the
# Posix utilities, the GNU C compiler, and so on.  On other systems,
# we use the native C library.

{system}: let
  { allPackages = import ./all-packages-generic.fix

  # The native (i.e., impure) build environment.  This one uses the
  # tools installed on the system outside of the Nix environment,
  # i.e., the stuff in /bin, /usr/bin, etc.  This environment should
  # be used with care, since many Nix packages will not build properly
  # with it (e.g., because they require GNU Make).
