我正在尝试使用boost :: bind将curried函数链接在一起,并获得无法解决的编译器错误.我可以做的最简单的例子,无法编译:

#include <iostream>
#include <boost/bind.hpp>

class A
{
public:
    template <typename F>
    void g(F fn, char c)
    {
        fn(c);
    }

    void h(char c)
    {
        std::cout << c << std::endl;
    }

    template <typename F>
    void f(F fn, char c)
    {
        boost::bind(&A::g<F>, this, fn, ::_1)(c);
    }
};

int main(int argc, char** argv)
{
    char c = 'a';
    A a;
    a.f(boost::bind(&A::h, &a, ::_1), c);
}

失败并出现此错误:
