title: Eclipse CDT could not find #include <__debug>
body: <p>Everything was fine last week when I click the build button for a c++ project and it would generate the binary and I can run the program properly. But today after I updated the "Command Line Tools" in the app store(Btw my laptop is mac OSX 10.10.2), when I click the build button, it will generate this error message </p>
  
  <p>/Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/iterator:341:10: fatal error: '__debug' file not found
  "#include &lt;__debug>"</p>
  
  <p>1 error generated.</p>
  
  <p>And I can no longer generate the binaries and run my program...</p>
  
  <p>I didn't change any of the settings in eclipse.</p>
  
  <p>So how can I fix this problem?</p>
