title: Unresolved <iostream> in Eclipse, Ubuntu
body: <p>Yes, it's <strong>this</strong> question again...</p>
  
  <p>Somehow, I cannot get this issue resolved.  Believe it or not, I have experience with Eclipse but only for Java development.  I have programmed in C++ using vi but not with Eclipse.</p>
  
  <p>I have installed:</p>
  
  <ul>
  <li>Ubuntu 12.04</li>
  <li>Eclipse 3.7.2</li>
  <li>GCC 4.6.3</li>
  <li>Eclipse CDT 8.0.2</li>
  </ul>
  
  <p>I created an empty Makefile project and selected the Linux GNU Toolchain:</p>

  <p>I get the standard <code>Unresolved inclusion &lt;iostream&gt;</code> error, and I have some references to various "include" directories in the project:</p>

  <p>I did notice that, while my "Paths and Symbols" setting for GNU C contains various paths, the same setting for GNU C++ is empty:</p>

  <p>Also, I have the "GNU Elf Parser" under my C/C++ build settings:</p>

  <p>Here's an updated photo of my a project's build path that is working correctly:
