|
||
|
||
<para>The <command>nix-build</command> command builds the derivations
|
||
described by the Nix expressions in <replaceable>paths</replaceable>.
|
||
If the build succeeds, it places a symlink to the result in the
|
||
current directory. The symlink is called <filename>result</filename>.
|
||
If there are multiple Nix expressions, or the Nix expressions evaluate
|
||
to multiple derivations, multiple sequentially numbered symlinks are
|
||
created (<filename>result</filename>, <filename>result-2</filename>,
|
||
and so on).</para>
|
||
|
||
<para>If no <replaceable>paths</replaceable> are specified, then
|
||
<command>nix-build</command> will use <filename>default.nix</filename>
|
||
in the current directory, if it exists.</para>
|
||
|
||
<para><command>nix-build</command> is essentially a wrapper around
|
||
<link
|
||
linkend="sec-nix-instantiate"><command>nix-instantiate</command></link>
|
||
(to translate a high-level Nix expression to a low-level store
|
||
derivation) and <link
|
||
linkend="rsec-nix-store-realise"><command>nix-store
|
||
--realise</command></link> (to build the store derivation).</para>
|
||
|
||
<warning><para>The result of the build is automatically registered as
|
||
a root of the Nix garbage collector. This root disappears
|
||
automatically when the <filename>result</filename> symlink is deleted
|
||
or renamed. So don’t rename the symlink.</para></warning>
|
||
|
||
<para>The subcommand <command>nix-build --run-env</command> will build
|
||
the dependencies of the derivation, but not the derivation itself. It
|
||
will then start an interactive shell in which all environment
|
||
variables defined by the derivation have been set to their
|
||
corresponding values, and the script <literal>$stdenv/setup</literal>
|
||
has been sourced. This is useful for reproducing the environment of a
|
||
derivation for development.</para>

<screen>
|
||
$ nix-build '<nixpkgs>' -A firefox
|
||
store derivation is /nix/store/qybprl8sz2lc...-firefox-1.5.0.7.drv
|
||
/nix/store/d18hyl92g30l...-firefox-1.5.0.7
|
||
|
||
$ ls -l result
|
||
lrwxrwxrwx <replaceable>...</replaceable> result -> /nix/store/d18hyl92g30l...-firefox-1.5.0.7
|
||
|
||
$ ls ./result/bin/
|
||
firefox firefox-config</screen>
|
||
|
||
<para>To build the dependencies of the package Pan, and start an
|
||
interactive shell in which to build it:
|
||
|
||
<screen>
|
||
$ nix-build '<nixpkgs>' --run-env -A pan
|
||
$ unpackPhase
|
||
$ cd pan-*
|
||
$ configurePhase
|
||
$ buildPhase
|
||
$ ./pan/gui/pan
|
||
</screen>
|
||
|
||
</para>
|
||
|
||
<para>If a derivation has multiple outputs,
|
||
<command>nix-build</command> will build the default (first) output.
|
||
You can also build all outputs:
|
||
<screen>
|
||
$ nix-build '<nixpkgs>' -A openssl.all
|
||
</screen>
|
||
This will create a symlink for each output named
|
||
<filename>result-<replaceable>outputname</replaceable></filename>.
|
||
The suffix is omitted if the output name is <literal>out</literal>.
|
||
So if <literal>openssl</literal> has outputs <literal>out</literal>,
|
||
<literal>bin</literal> and <literal>man</literal>,
|
||
<command>nix-build</command> will create symlinks
|
||
<literal>result</literal>, <literal>result-bin</literal> and
|
||
<literal>result-man</literal>. It’s also possible to build a specific
|
||
output:
|
||
<screen>
|
||
$ nix-build '<nixpkgs>' -A openssl.man
|
||
</screen>
|
||
This will create a symlink <literal>result-man</literal>.</para>
