How to construct Boost bimap from static list?

I use the following "factory function" that takes a braced initializer list and returns a boost::bimap:

template <typename L, typename R>
boost::bimap<L, R>
makeBimap(std::initializer_list<typename boost::bimap<L, R>::value_type> list)
{
    return boost::bimap<L, R>(list.begin(), list.end());
}

Usage:

auto myBimap = makeBimap<int, int>({{1, 2}, {3, 4}, {5, 6}});

The iterator begin/end should be for a sequence of bimap values.

boost::bimap< A, B>::value_type

A bimap value is a lot like a std::pair and can be initialized with {a1, b1}syntax. A vector of them seems to work too, which provides usable iterators for the constructor.

Ok, here is an example that compiles and runs for me (gcc 4.8.2 --std=c++11)

#include <vector>
#include <boost/bimap.hpp>

using namespace std;
int main() {
    typedef boost::bimap< int, int > MyBimap;

    std::vector<MyBimap::value_type > v{{1, 2}, {3, 4}, {5, 6}};

    MyBimap M(v.begin(),v.end());

    std::cout << "The size is " << M.size()
              << std::endl;

    std::cout << "An entry is 1:" << M.left.at(1)
              << std::endl;
}

C++ beginner here: You can use boost::assign to generate the initialization. I found this solution here.

Example:

#include <boost/bimap.hpp>
#include <boost/assign.hpp>

//declare the type of bimap we want
typedef boost::bimap<int, std::string> bimapType;
//init our bimap
bimapType bimap = boost::assign::list_of< bimapType::relation >
( 1, "one"   )
( 2, "two"   )
( 3, "three" );

//test if everything works
int main(int argc, char **argv)
{
    std::cout << bimap.left.find(1)->second << std::endl;
    std::cout << bimap.left.find(2)->second << std::endl;
    std::cout << bimap.left.find(3)->second << std::endl;
    std::cout << bimap.right.find("one")->second << std::endl;
    std::cout << bimap.right.find("two")->second << std::endl;
    std::cout << bimap.right.find("three")->second << std::endl;

    /* Output:
     * one
     * two
     * three
     * 1
     * 2
     * 3
     */
}
