title: What is the archive target member name in makefile?
body: <p>What is the target member name in an archive in a makefile?</p>
  
  <p>It is explained here: <a href="https://www.gnu.org/software/make/manual/html_node/Archive-Members.html#Archive-Members" rel="nofollow">https://www.gnu.org/software/make/manual/html_node/Archive-Members.html#Archive-Members</a>
  but I don't quite understand it since there's not a brief example.</p>
  
  <p>If I have </p>
  
  <pre><code>target(name): name
         echo $%
  </code></pre>
  
  <p><code>$%</code> is the automatic variable for target name.</p>
  
  <p>If I use <code>make target</code>, this won't run</p>
  
  <p>why? What is "target member name" actually?</p>
