|

referred to <xref linkend='chap-installation' /> and <xref

Download a source tarball or RPM from <ulink

Build source distributions using the regular sequence:
|
|
|
|
<screen>
|
|
$ tar xvfj nix-<replaceable>version</replaceable>.tar.bz2
|
|
$ ./configure
|
|
$ make
|
|
$ make install <lineannotation>(as root)</lineannotation></screen>
|
|
|
|
This will install Nix in <filename>/nix</filename>. You
|
|
should also add <filename>/nix/etc/profile.d/nix.sh</filename>
|
|
to your <filename>~/.bashrc</filename> (or some other login
|
|
file).

Get some Nix expressions for pre-built packages by downloading
|
|
the latest <literal>nixpkgs</literal> distribution (from the
|
|
same location), and unpack them.
|
|
|
|
<screen>
|
|
$ wget http://<replaceable>...</replaceable>/nix/nixpkgs-<replaceable>version</replaceable>/nixpkgs-<replaceable>version</replaceable>.tar.bz2
|
|
$ tar xfj nixpkgs-<replaceable>version</replaceable>.tar.bz2</screen>
|
|
|
|
This will unpack the distribution into a directory
|
|
<filename>nixpkgs-<replaceable>version</replaceable>/</filename>.

Pull the Nix cache. This ensures that when you install
|
|
packages they are downloaded in pre-built form from the
|
|
network, rather than built from source.

|

$ nix-pull http://<replaceable>...</replaceable>/nix/nixpkgs-<replaceable>version</replaceable>/</screen>

platforms.

If a new release of <literal>nixpkgs</literal> comes along,
|
|
you can upgrade all installed packages to the latest versions
|
|
by downloading and unpacking the new release and doing:
|
|
|
|
<screen>
|
|
$ nix-env -uBf nixpkgs-<replaceable>version</replaceable>/ '*'</screen>

You should periodically run the Nix garbage collector to get
|
|
rid of unused packages, since uninstalls or upgrades don't
|
|
actual delete them:
|
|
|
|
<screen>
|
|
$ nix-collect-garbage | xargs nix-store --delete</screen>
