Class : unresolved external symbol error.

[Arquon]

Hello, I am receiving unresolved external symbol error while working with 3 seperate files : main.cpp, class.h, and class.cpp.
Main:

#include <iostream>
#include "Grum.h"
using namespace std;

int main()
{
    Grum gru;
      return 0;
}

Class header:

#ifndef GRUM_H
#define GRUM_H


class Grum
{
    public:
         Grum();
};

#endif // GRUM_H 

Grum.cpp:

#include <iostream>
#include "grum.h"
using namespace std;
Grum::Grum()
{
    cout << "grum" << endl;
}

Could I please know where did I make a mistake and how to fix it ? Thank you.

It's in the Grum.cpp File. Look at the include.

#include "grum.h"

Should be a big g right? #include "Grum.h"

Ensure you are compiling Grum.cpp and linking the resultant object code.

If you're using an IDE, make sure Grum.cpp is a part of the project. If you're using the command line, make sure it is correct and you enumerate Grum.cpp as one of the files to be compiled/linked.

Should be a big g right?

If that were the problem it wouldn't have got to the linking stage.

Oh, yes, im using CodeBlocks IDE and my Grum.cpp wasnt part of the project. I put it in the project now and I seem to be getting even more unresolved external errors. All of their file names seems to be starting with lib and the last one being the directory of project.exe
