How to Compile boost with GCC 5 using old ABI?

I have downloaded a library that was compiled with a gcc 4.8 before the ABI change in GCC.

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

undefined symbol.....__cxx11....

How can I install boost using old ABI with GCC5 ?
