Boost Multiprecision random generator seed error

I have been following the documentation from the boost library to generate multiprecision random integers but In the documentation it is not mentioned how to set the seed.

I can't figure how to set the seed without getting compilation errors.

#include <boost/multiprecision/gmp.hpp>     
#include <boost/multiprecision/random.hpp>  
#include <fstream>  

using namespace boost::multiprecision;
using namespace boost::random;
using namespace std;

//...    

typedef independent_bits_engine<mt19937, N_BITS, mpz_int> generator_type;

int main() 
{
    // ...

    generator_type gen;
    seed_seq sed_seq = { 12064, 3867, 13555, 28676, 4599, 5031, 13040 };
    gen.seed(sed_seq); 

    // ...

    for(unsigned i = 0; i < SS; ++i)  {
     out
        << gen()
        << endl;
    }

    out.close();
    return 0;
}

How do I compile:

$ g++ generateinputs.cpp -o generateinputs.o -L/gmp_install/lib -lgmp

And this are the compilation errors that I get:

generateinputs.cpp: In function ‘int main()’:
generateinputs.cpp:35:68: error: in C++98 ‘sed_seq’ must be initialized by constructor, not by ‘{...}’
  seed_seq sed_seq = { 12064, 3867, 13555, 28676, 4599, 5031, 13040 };
                                                                    ^
generateinputs.cpp:35:68: error: could not convert ‘{12064, 3867, 13555, 28676, 4599, 5031, 13040}’ from ‘<brace-enclosed initializer list>’ to ‘boost::random::seed_seq’

I have also tried to compile with c++11 but I still have errors. ¿Can you show me how It's done?
