I just installed Ubuntu 12.10, and I tried to install Eclipse and C++, but I failed miserably.

I started with an installation from the Software Center, Eclipse worked, but only in Java. Then I started googling for installation guides and tutorials, but after hours of downloads and installations, the C++ in Eclipse still doesn't work.

So now I have two questions:

  1. How do I clean up this mess?
    Actually, how do I know if there is a mess?
    According to the Ubuntu Software Center, Eclipse is installed and has three add-ons.
    How do I know if the other installations of other Eclipse versions/packagings overwrote each other or if I have multiple installations?

  2. How do I install the latest version of Eclipse and C++ in Ubuntu 12.10?

c++ eclipse ubuntu installation
