[Boost-users] mixing c++98 with c++11

Hello, Please consider the following: application A depends on boost compiled libraries application A depends on library B library B depends on boost compiled libraries Q1: Will I have a problem if: application A is compiled with gcc c++11 library B is compiled with gcc c++98 boost compiled with gcc c++98 Q2: Will I have a problem if: application A is compiled with gcc c++11 library B is compiled with gcc c++11 boost compiled with gcc c++98 My concern is that boost produces different code in its headers based on whether or not the compiler supports c++11. Thank you, Chris
