Hi, 

I would like to share my experience with boost when combining with c++11. I hope it might help someone. 

Suppose a simple program:

#include <boost/asio.hpp>

#include <iostream>

using boost::asio::detail::atomic_count;

struct Test

{

  // Whether the task has been interrupted.

  bool         task_interrupted_;

  // The count of unfinished work.

  atomic_count outstanding_work_;

};

int main ()

{

    std::cout << "Size is " << sizeof(Test) << std::endl;

    return 0;

}

 

And here is the story:

$ /opt/gcc-4.8.4/bin/g++ -std=c++11 -I /opt/boost-1.58.0/include/ -L /opt/boost-1.58.0/lib -lboost_system b.cpp

$ ./a.out

Size is 16

$ /opt/gcc-4.8.4/bin/g++ -I /opt/boost-1.58.0/include/ -L /opt/boost-1.58.0/lib -lboost_system b.cpp

$ ./a.out

Size is 8

It means that c++11 program cannot be linked with boost libraries compiled without "-std=c++11" option. It was asio in my case and the program was linked with libboost_log.so.1.58.0.
