title: Eclipse indexing not working
body: <p>I am using CDT in Eclipse 3.5.2 Galileo in Ubuntu. </p>
  
  <p>My eclipse's indexer doesn't work at times. By that I mean when I <code>ctrl</code> click a function it says <code>Could not find symbol in index</code>. Also, F3 button click results in the same error message. Actually most of the places it is not working and works in very few places.</p>
  
  <p>I have seen some other versions of Eclipse where under File menu a menu item listed for Indexing. Like File->Indexer->Rebuild.... But in my File menu there is no such menu item for the Indexer.</p>
  
  <p>Will the only way be to use some other release of Eclipse or am missing something? Any pointers regarding this would be helpful.</p>
