使用std :: bind了解编译器错误

Question

如何编译：

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

inline void print(std::string string1, std::string* string2)
{
    std::cout << string1 << " " << string2 << std::endl;
    delete string2;
}

class class1
{
    public:
        std::string foo{"Hello"};
        std::shared_ptr<std::string> foo2;
        class1();
};

class1::class1()
{
    auto boundFunc = std::bind(print, foo, std::placeholders::_2);
    foo2 = std::shared_ptr<std::string>(new std::string("world"), boundFunc);
}

int main()
{
    class1 test;
}

GCC提供了一长串错误的错误消息：

我不知道该输出是做什么的，我还没有找到任何关于std :: bind的好文档，它提供了可以使用它的各种方式的示例，只有最基本的情况。

stackoverflow需要更多细节，但我甚至不知道还能提供什么。从代码中可以明显看出问题是什么。如果我知道该说些什么我就可以搜索它，但我不知道如何描述这个问题。
