title: How to install g++ 4.9 on Debian Wheezy armel?
body: <p>My Debian 7 armel embedded system currently has g++ 4.6, and I'd like to upgrade to g++ 4.9 to use new C++11 features.  How do I do that?</p>
  
  <p>My current sources.list contents is:</p>
  
  <pre>
  
      deb http://security.debian.org/ wheezy/updates main
      deb-src http://security.debian.org/ wheezy/updates main
      deb http://ftp.us.debian.org/debian wheezy main non-free
      deb-src http://ftp.us.debian.org/debian wheezy main non-free
  
  </pre>
  
  <p>A simple apt-get install of the package does not work:</p>
  
  <pre>
  
      root@arm:~#  apt-get install g++-4.9
