title: Compiler can't find libxml/parser.h
body: <p>I am on Debian 8 (Jessie), 64 Bit. I installed <code>libxml2-dev</code>, which now sits in <code>/usr/include/libxml2/libxml</code>.</p>
  
  <p>But when I do (just like <code>libxml</code> docs say)</p>
  
  <pre><code>#include &lt;libxml/parser.h&gt;
  </code></pre>
  
  <p>I only get when compiling (with <code>gcc</code>)</p>
  
  <pre><code>fatal error: libxml/parser.h: no such file or directory
  </code></pre>
  
  <p>Notes: On another machine, with an old 64 Bit Suse, where <code>libxml2-dev</code> sits in the exact same path and no other environment vars are set compared to the new Debian, it works perfectly fine. Problem occured while migrating from one to another computer using the exact same makefiles. <strong>All</strong> other <code>-dev</code> libs that I need just worked (with their documented <code>#include &lt;path&gt;</code>) after the migration (they were all installed with <code>apt-get</code>), only <code>libxml2-dev</code> is not found on compilation.</p>
  
  <p>Do I need to do anything else to make <code>libxml2-dev</code> visible?</p>
