title: Explaining "g++ not found in PATH" for an idiot
body: <p>So, I just installed Eclipse for C/C++ and whenever I make a new project, I get two errors saying that the programs g++ and gcc are not in my PATH. All of the answers I have found so far have talked about directories, and opening up my path and changing code in there. I don't know anything about directories or paths, so I don't know what any of these answers mean. Can someone offer me a simple, easy to understand answer that walks me through what I need to do?</p>
  
  <p>P.S. I have installed MinGW onto my computer, but when I create a new project, it doesn't come up as an option for which toolchain to use. The only options I get are Cross GCC and Microsoft Visual C++. When I choose the former, it asks for the cross compiler prefix and the cross compiler path, and I don't know what those mean, either. When I choose the latter, I still get the errors anyway.</p>
  
  <p>P.P.S. Thanks in advance to anyone who can give me an answer that both helps and is easy to understand for someone like me.</p>
