title: eclipse c++ build error
body: <p>I'm having a problem with eclipse C++ juno. My project compiles and runs from command line but eclipse (juno) keeps saying there are thousands of errors. For example there's a function SetRun in my code, and eclipse mentions this error: "called Invalid arguments 'Candidates are: void SetRun(?)'", whereas SetRun is of type static void SetRun (uint32_t run);</p>
  
  <p>I have quite a lot of similar errors like that, where eclipse doesn't seem to understand the type of the function and puts a '?' instead.</p>
  
  <p>I also have many errors like this: "symbol '*' could not be resolved."</p>
  
  <p>I also have many includes that can't be resolved, although they are resolved just fine by the compiler.</p>
  
  <p>I think this is all part of the same issue.</p>
  
  <p>I should also note that I had this working with eclipse previously, but now everytime I open eclipse it appears that way.</p>
  
  <p>If I build the project from eclipse, it build successfully.</p>
  
  <p>I tried updating the index but it didn't change a thing.</p>
  
  <p>What can I do to make eclipse stop telling me about these errors?</p>
  
  <p>edit:</p>
  
  <p>here is an example of a include that is not resolved:</p>
  
  <pre><code>#include "ns3/core-module.h"
  </code></pre>
