Hello,
I am trying to initialize a bimap with a vector>
(the "vector" part isn't important, any range with elements
of type pair has the same effect), but I'm getting a rather
monstrous compiler error.
The same initialization works for std::map.
Here is the code:
#include
#include
#include
#include <vector>
#include <map>
#include <utility>
int main()
{
int i1, i2;
float f1, f2;
std::vector> myvec{{i1, f1}, {i2, f2}};
std::map m(boost::begin(myvec), boost::end(myvec)); // WORKS
boost::bimap b(boost::begin(myvec), boost::end(myvec)); // FAILS
}
The compiler errors are shown below.
It seems to me this should work. As with std::map, the pair-of-iterators
constructor should call something like insert(const value_type&) for each
element of the range, where value_type is something like pair
which should be constructible from pair, the element type
of the range.
Why is this not working?
Thanks,
Nate.
P.S. Here are the errors:
