使用boost :: function和boost :: bind

我有以下代码尝试将非静态成员函数作为替换想法传递给需要功能指针的旧c代码。它没有编译。你能帮忙吗？某些事情必须很明显，对此我是陌生的。提前致谢。-锦屏

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


using namespace boost;
using namespace std;

double addTest( boost::function<double (double)> f, double a, double x )
{

    double a1 = f(a);

    double a2= a1+x;

    return a2;
}

double squareIt (double x) {
    return x*x;
}

class X {
public:
    X(double x0, double x1){ x=x0+x1; }

    double plusIt(double t) { return x+t; }
private:

    double x;

};
int main (int argc, char** argv)
{
    boost::function<double (double)> f;
    f = &squareIt;

    double result = addTest(f, 10, 5);   //OK

    cout << "result = " << result << endl;

    X newx(10, 15);

    //f=boost::bind(&X::plusIt, &newx);   // does not complie
    double res2 = addTest(boost::bind(&X::plusIt, &newx), 10, 5);  // does  not compile

    cout << "result2 = " << res2 << endl;

    return 0;
}

//编译错误：
