title: How to add <mhash.h> into my C project
body: <p>I'm trying to run this code on Eclipse. But there is an error about the header <strong>mhash.h</strong></p>
  
  <h2>"Error: No such a file or directory"</h2>
  
  <p><strong>The code is this:</strong></p>
  
  <pre><code>#include &lt;mhash.h&gt;
  #include &lt;stdio.h&gt;
  #include &lt;stdlib.h&gt;
  int main(void)
  {
      int i;
      MHASH td;
      unsigned char buffer;
      unsigned char *hash;
      td = mhash_init(MHASH_MD5);
      if (td == MHASH_FAILED) exit(1);
      while (fread(&amp;buffer, 1, 1, stdin) == 1) {
              mhash(td, &amp;buffer, 1);
      }
      hash = mhash_end(td);
      printf("Hash:");
      for (i = 0; i &lt; mhash_get_block_size(MHASH_MD5); i++) {
              printf("%.2x", hash[i]);
      }
      printf("\n");
      exit(0);
  }
