<refsection><title>Description</title>
|
||
|
||
<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>
