title: Why is there a compile error when including OpenSSL static library?
body: <p>I have some problems using OpenSSL.  I'm following the <a href="http://www.x2on.de/2010/07/13/tutorial-iphone-app-with-compiled-openssl-1-0-0a-library/" rel="nofollow noreferrer">tutorial for compiling OpenSSL for iOS</a>, but it is still not working.  Here is my problem:</p>
  
  <ol>
  <li>Change directories into <code>crypto/ui/ui_openssl.c</code>.</li>
  <li>Build OpenSSL for i368 iPhone simulator.</li>
  <li>Copy the <code>include</code>, <code>libcrypto.a</code> and <code>libssl.a</code> to the project folder.</li>
  <li>Drag <code>libcrypto.a</code> and <code>libssl.a</code> to project tree.</li>
  <li>Change the build info.</li>
  </ol>
  
  <p>It worked with <code>openssl-1.0.0c</code>.  Then as I was coding <code>#include &lt;openssl/md5.h&gt;</code> and building, I got the error "no such file or directory."
