我正在尝试在 mex 文件中使用 c++ 静态库，但我无法链接它。

这是我试图混合的 cpp 文件的来源：

#include <math.h>
#include <matrix.h>
#include <mex.h>
#include <iostream>
#include "pbogus.h"



void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
pbogus p;
int x=p.fbogus(2);

 mexPrintf("%d",x);

 }

这是我的“库”的头文件和源代码：

//header
#ifndef PBOGUS_H
#define PBOGUS_H

class pbogus
{

public:
int fbogus(int );
};


#endif


//source
#include "pbogus.h"

int pbogus::fbogus(int x)
{
return 2*x;

}

该库名为testsymcpp.lib

这是我正在使用的 mex 命令：

 mex -v -L. -ltestsymcpp hello.cpp

这是输出：
