title: Eclipse C++ inline type checking failing to find libstdc++ classes
body: <p>I have eclipse installed with CDT on windows(7) . I installed MinGW. I pointed my include files directory at </p>
  
  <p>c:\MinGW</p>
  
  <p>I started a simple project with a class that basically just includes <code>&lt;string&gt;</code> and <code>&lt;iostream&gt;</code></p>
  
  <p>The "hint icons" in the gutter are telling me that <code>&lt;iostream&gt;</code> and <code>&lt;string&gt;</code> are unresolved includes, but make is building my project just fine. This problem is subsequently leading to my definitions that rely on string not getting recognized.</p>
  
  <p>How do I resolve the problem so that the IDE recognizes the includes the same way make does?</p>
  
  <p>This is eclipse 3.7.1 .</p>
