如何使用std :: bind编译c ++程序？

Question

I want to compile this simple test.cpp program from Wrox's Professional C++ :

#include<iostream>
#include<functional>
using namespace std;

void func(int num, const string& str)
{
            cout << num << ' ' << str << endl;
}

int main()
{
    string str = "abc";
    auto f = bind(func, placeholders::_1, str);
    f(16);
}

I have g++ (Debian 4.4.5-8) 4.4.5 compilator and I use it like that:

g++ -std = c++0x test.cpp -o test

I get error:

error: no match for call to ‘(std::_Bind<void (*(std::_Placeholder<1>, int))
(int, int)>) (int)’

Why the program does not compile?

I cannot compile the example program from C++ Reference as well.

std::bind是C ++ 11，g ++ 4.4不支持你需要通过系统升级或使用/ etc / apt / preferences软件包绑定至少升级到Debian Wheezy的g ++ 4.7
