title: Integrating jsoncpp by including amalgamated source in Xcode
body: <p>I'm struggling with a Linker error in Xcode. I've created the amalgamated source, added the jsoncpp.cpp as a source file to my project, I've set the header search path to jsoncpp-master/dist and use</p>
  
  <pre><code>#include "json/json.h"
  #include "json/json-forwards.h"
  </code></pre>
  
  <p>as described at <a href="https://github.com/open-source-parsers/jsoncpp" rel="nofollow">https://github.com/open-source-parsers/jsoncpp</a>. Still, I'm getting an undefined symbols error: </p>
  
  <pre><code> Undefined symbols for architecture x86_64:
     "output(Json::Value)", referenced from:
        _main in main.o
   ld: symbol(s) not found for architecture x86_64
   clang: error: linker command failed with exit code 1 (use -v to see invocation)
