title: Why are the C++ perspective and new project options not available in Eclipse?
body: <p>I installed the "Eclipse IDE for Java Developers" package from the Eclipse website. I work with C++ projects as well, so I used the "Install New Software..." menu option to install the "C/C++ Development Tools" package. After doing so and restarting Eclipse, the C++ perspective did not appear; clicking on the "Open Perspective" button did not show the "C/C++" option. I also found that I was unable to create a C++ project; the "C/C++" tree node did not appear in the New Project wizard. The Java perspective and new project options were available.</p>
  
  <p>I verified that CDT was installed by going to the "Installed Installation Details" dialog - "C/C++ Development Tools" appeared in the "Installed Software" list. I tried uninstalling this package and reinstalled it again without success. I tried removing the Eclipse installation altogether and installing the "Eclipse IDE for C/C++ Developers". There were no C/C++ options in this installation either. I checked the <code>.log</code> file in the workspace directory and found nothing unusual.</p>
  
  <p>Why are the C/C++ features not available after installing the CDT feature in Eclipse?</p>
