#include <boost/assign.hpp>

#include <vector>

#include <iterator>

#include <algorithm>

#include <iostream>

using namespace std;

using namespace boost;

using namespace boost::assign;

int main(int argc, char* argv[])

{

typedef vector<int> int_vec;

int_vec v = list_of(1)(2);

int_vec v2(2);

v2=list_of(1)(2).to_container(v2);

ostream_iterator<int> oiter(cout, ",");

copy(v2.begin(), v2.end(), oiter);

}

Hope that helps,

Sorry, it must be to_container() and not to_adapter().

The code is compilable on msvc but is not on gcc-4.3:

But the problem occurs when i try to initialise std::vector in a class initialization list:
class sss
{

  std::vector<int> v;

  sss()
   : v(boost::assign::list_of(1)(2))
  {}
};

What happens if you call:
sss()
   : v(boost::assign::list_of(1)(2).to_adapter())

  {}

list_of implements 2 members:
implicit conversion opertor to the container type and the to_adapter member. You can cast list_of instance to your vector<int> if that with adapter does not work. Other solution can be:

If you need efficiency, you still can use the vector ctor which reserves the number of items in a vector and than copies
the elements from the list.

sss() : v(2)
{
  v = list_of...;
}
