windows创建和调用静态库 

            //
             MathFuncsLib.h
            namespace
             MathFuncs
{
    
            class
             MyMathFuncs
    {
    
            public
            :
        
            //
             Returns a + b
            static
            double Add(double a, double b);

        // Returns a - bstaticdouble Subtract(double a, double b);

        // Returns a * bstaticdouble Multiply(double a, double b);

        // Returns a / bstaticdouble Divide(double a, double b);
    };
} 
// MathFuncsLib.cpp
// compile with: cl /c /EHsc MathFuncsLib.cpp
// post-build command: lib MathFuncsLib.obj

#include "MathFuncsLib.h"

#include <stdexcept>

using namespace std;

namespace MathFuncs
{
    double MyMathFuncs::Add(double a, double b)
    {
        return a + b;
    }

    double MyMathFuncs::Subtract(double a, double b)
    {
        return a - b;
    }

    double MyMathFuncs::Multiply(double a, double b)
    {
        return a * b;
    }

    double MyMathFuncs::Divide(double a, double b)
    {
        return a / b;
    }
}

调用静态库

// MyExecRefsLib.cpp
// compile with: cl /EHsc MyExecRefsLib.cpp /link MathFuncsLib.lib

#include <iostream>

#include "MathFuncsLib.h"

using namespace std;

int main()
{
    double a = 7.4;
    int b = 99;

    cout << "a + b = " <<
        MathFuncs::MyMathFuncs::Add(a, b) << endl;
    cout << "a - b = " <<
        MathFuncs::MyMathFuncs::Subtract(a, b) << endl;
    cout << "a * b = " <<
        MathFuncs::MyMathFuncs::Multiply(a, b) << endl;
    cout << "a / b = " <<
        MathFuncs::MyMathFuncs::Divide(a, b) << endl;

    return 0;
}

windows创建和调用动态库 

// MathLibrary.h - Contains declaration of Function class  
#pragma once  

#ifdef MATHLIBRARY_EXPORTS  
#define MATHLIBRARY_API __declspec(dllexport)   
#else  
#define MATHLIBRARY_API __declspec(dllimport)   
#endif  

namespace MathLibrary  
{  
    // This class is exported from the MathLibrary.dll  
    class Functions  
    {  
    public:  
        // Returns a + b  
        static MATHLIBRARY_API double Add(double a, double b);  

        // Returns a * b  
        static MATHLIBRARY_API double Multiply(double a, double b);  

        // Returns a + (a * b)  
        static MATHLIBRARY_API double AddMultiply(double a, double b);  
    };  
}  


// MathLibrary.cpp : Defines the exported functions for the DLL application.  
// Compile by using: cl /EHsc /DMATHLIBRARY_EXPORTS /LD MathLibrary.cpp  

#include "stdafx.h"  
#include "MathLibrary.h"  

namespace MathLibrary  
{  
    double Functions::Add(double a, double b)  
    {  
        return a + b;  
    }  

    double Functions::Multiply(double a, double b)  
    {  
        return a * b;  
    }  

    double Functions::AddMultiply(double a, double b)  
    {  
        return a + (a * b);  
    }  
}

调用动态库

// MathClient.cpp : Defines the entry point for the console application.  
// Compile by using: cl /EHsc /link MathLibrary.lib MathClient.cpp  

#include "stdafx.h"  
#include <iostream>  
#include "MathLibrary.h"  

using namespace std;  

int main()  
{  
    double a = 7.4;  
    int b = 99;  

    cout << "a + b = " <<  
        MathLibrary::Functions::Add(a, b) << endl;  
    cout << "a * b = " <<  
        MathLibrary::Functions::Multiply(a, b) << endl;  
    cout << "a + (a * b) = " <<  
        MathLibrary::Functions::AddMultiply(a, b) << endl;  

    return 0;  
}
