title: How to Compile boost with GCC 5 using old ABI?
body: <p>I have downloaded a library that was compiled with a gcc 4.8 before the ABI change in GCC. </p>
  
  <p>On my laptop (latest kubuntu) I have GCC 5.2. And When I installed boost, it seems that it used the new ABI but then I get the following link errors</p>
  
  <p>undefined symbol.....__cxx11....</p>
  
  <p>How can I install boost using old ABI with GCC5 ?</p>
