title: How to use ezpwd reed-solomon error correction library
body: <p>I want to generate QR codes, and for this I need Reed-Solomon error correction encode and decode (for future reading QR codes). I found this commercial library: <a href="https://github.com/pjkundert/ezpwd-reed-solomon" rel="nofollow">https://github.com/pjkundert/ezpwd-reed-solomon</a> and I want to try it. It's said that this library works with C++ and javascript, I want to use it under C++ QT. I downloaded source code from github, put ezpwd folder in my project and I try to use this sample code:</p>
  
  <pre><code>#include &lt;QCoreApplication&gt;
  #include &lt;ezpwd/rs&gt;
  #include &lt;vector&gt;
  #include &lt;stdint.h&gt;
  
  using namespace std;
  
  int main(int argc, char *argv[])
  {
  QCoreApplication a(argc, argv);
  
  vector&lt;int8_t&gt; data;
  
  
  ezpwd::RS&lt;255,251&gt; rs;
  rs.encode( data);
  
  return a.exec();
  }
  </code></pre>
  
  <p>But this error occurs:</p>
  
  <pre><code>dependent '..\reed_solomon_lib_test\rslib.h' does not exists
  </code></pre>
  
  <p>It is first time I see something like this, usually there should be some header .h and sourse .cpp files). I was searching for this rslib.h but there is no such file in directory that I downloaded from github.
  I think I don't know about step that everyone knows, something like build this library first. Please explain what should I do to use this library.</p>
