<h1 id="build-target-build_tgt-extends-tgt">Build target (<code>build_tgt</code> extends <a href="Reference-manual_returned_tgt.html"><ins><code>tgt</code></ins></a>)</h1>
<p>A build target is either an executable, shared library, static library,
both shared and static library or shared module.</p>
<h2 id="extended-by">Extended by</h2>
<p>Build target is extended by the following subtypes:</p>
<ul>

</ul>
<h2 id="returned-by">Returned by</h2>
<p>Build target objects are returned by the following functions and methods:</p>
<ul>
<li><a href="Reference-manual_functions.html#build_target"><ins><code>build_target()</code></ins></a></li>

<p>By default only objects built for this target are returned to maintain
backward compatibility with previous versions. The default value for the

<h3 id="build_tgtextract_objects">build_tgt.extract_objects()</h3>
<p>Returns an opaque value representing the object files generated for those
source files. This is typically used to take single object files and link
them to unit tests or to compile some source files with custom flags. To
use the object file(s) in another build target, use the
<code>objects:</code> keyword argument to a <a href="Reference-manual_functions.html#build_target"><ins><code>build_target()</code></ins></a> or <a href="Reference-manual_functions.html#declare_dependency"><ins><code>declare_dependency()</code></ins></a>,

correctly. Please file a bug if that doesn't work for you.</p>
