title: error LNK2001: unresolved external symbol "__declspec(dllimport) public: class QString & __thiscall QString::operator=(class QString &&)"
body: <p>I'm desperate about finding any information about the mentioned error.</p>
  
  <p>I'm working on visual studio 2010. When I compile my project (in 32 bits), in debug or release, I get the following message :</p>
  
  <blockquote>
    <p>1>heterogeneous.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: class QString &amp; _<em>thiscall QString::operator=(class QString &amp;&amp;)" (</em>_imp_??4QString@@QAEAAV0@$$QAV0@@Z)</p>
    
    <p>1>debug\nori.exe : fatal error LNK1120: 1 unresolved externals</p>
  </blockquote>
  
  <p>I linked QtCore4.lib in Linker->Input, I added Qt\4.8.2\lib to the library directories in Linker->General, and I included Qt\4.8.2\include and Qt\4.8.2\include\QtCore in C/C++->General. It seems to me that they are supposed to define QString. I don't know what else I could do.</p>
  
  <p>Thank you very much for your help.</p>
