title: how to use gcc 4.4.7 to compile C++ code with the C++11 features
body: <p>I am studying a algorithm code which uses some c++11 features, however my linux system only has the gcc4.4.7 and I donot have permission to update this version. I was told that by running some kind of scripts can solve this problem, that means using gcc4.4.7 can still compile the c++ code which has the c++11 features. </p>
  
  <p>my problem is that currently I only have gcc4.4.7 in linux system, so I wander if there is a solution that can help me compile a algorithm code which uses the c++11 features like the keyword "nullptr","constexpr" and so on, just using gcc4.4.7. </p>
  
  <p>By the way,I have already know that gcc4.7 and above can support c++11.</p>
  
  <p>Thank you very much!</p>
