title: Make cannot find tools.jar
body: <p>Running Ubuntu 12.04 </p>
  
  <p>I have added to PATH: <code>/home/jeffrey/jdk1.6.0_43/lib</code></p>
  
  <p>I am attempting to build from source using Make:</p>
  
  <pre><code>make -j16
  </code></pre>
  
  <p>But encounter the error:</p>
  
  <pre><code>build/core/config.mk:268: *** Error: could not find jdk tools.jar, please install JDK6, which you can download from java.sun.com.  Stop.
  </code></pre>
  
  <p>Can anyone explain to me why Make cannot find <code>tools.jar</code>?</p>
