Hi,
I am learning how to build and use a dll.
In Visual Studio 2010, I created a dll project.
Added header file
MathDll.h
1 2 3 4 5 6 7
|
#include <iostream>
class MathDll
{
public:
static __declspec(dllexport) int Sum(int, int);
};
|
Added cpp file
1 2 3 4 5 6 7 8 9 10
|
#include <iostream>
using namespace std;
#include "MathDll.h"
int MathDll::Sum(int a, int b)
{
return a+b;
}
|
I then built the solution.
It generated MathDll.dll
I copied MathDll.dll, MathDll.lib and MathDll.h and pasted in the project folder of a new console application.
This console application would use the above dll.
I added the MathDll.h header file in its Header folder
Created a main.cpp
1 2 3 4 5 6 7 8 9 10 11
|
#include <iostream>
#include "MathDll.h"
using namespace std;
int main()
{
int c = MathDll::Sum(5, 7);
cout << c << endl;
}
|
When I build this project, its giving the following error
1>main.obj : error LNK2019: unresolved external symbol "public: static int __cdecl MathDll::Sum(int,int)" (?Sum@MathDll@@SAHHH@Z) referenced in function _main
Debug\MathTest.exe : fatal error LNK1120: 1 unresolved externals

1>Build FAILED.
Please advice what I am doing wrong here.
Thank you
I
