<p>I am trying to build android app. When I run the zip align tool to optimize the APK, I get this error message:</p>

<pre><code>zipalign: error while loading shared libraries: libc++.so: cannot open shared object file: No such file or directory
</code></pre>

<p>I tried to install libc++ </p>

<pre><code>sudo aptitude install libc++
