xcode – c functional / std :: bind不能用Apple Clang编译

#include <iostream>
#include <functional>
#include <memory>

void foo(std::shared_ptr<int> b,unsigned int i)
{
  std::cout << *b << " - " << i << std::endl;
}

int main()
{
  using namespace std::placeholders;

  typedef std::function<void(std::shared_ptr<int> b,unsigned int i)> Foo;
  typedef std::function<void(unsigned int codE)> Bar;

  Foo f1 = foo;
  Bar f2 = std::bind(f1,std::make_shared<int>(10),_1);

  f2(0);

  return 0;
}

g -4.7 –version给出g -4.7(GCC)4.7.1

g++-4.7 -std=c++11 test.cpp && ./a.out
10 - 0

c –version给出了Apple clang 4.0版(标签/ Apple / clang-421.0.60)(基于LLVM 3.1svn)

我的代码有问题吗？

谢谢.
