Build Errors in my C++ program

Question

This is my third C++ application, so I am a beginner. Please have a look at the following code

Main.cpp

#include<iostream>
#include <string>
#include "GradeBook.h"

using namespace std;

int main()
{
    GradeBook myGradeBook1("Java");
    GradeBook myGradeBook2("C++");

    cout << "Course Name is: " << myGradeBook1.getCourseName() << endl;
    cout << "Course Name2 is: " << myGradeBook2.getCourseName() << endl;
}

GradeBook.h

#include <iostream>
#include <string>

using namespace std;

class GradeBook
{
private:
    string courseName;

public:

    GradeBook(string name)
    {
        setCourseName(name);
    }

    void setCourseName(string name)
    {
        courseName = name;
    }

    string getCourseName()
    {
        return courseName;
    }

    void displayMessage()
    {
        cout << "Welcome to " << getCourseName() << endl;
    }
};

Now, when I run the program (I use netbeans, compiler is cygwin), it gives the following error:

Seems like you're building a GUI app (WinMain is the entry point for those). Change it to Console app in your IDE. — jrok

Close all unrelated projects. If you don't have any unrelated projects please move your project files into a new project. — Zeta

Hi guys, Thanks for the help. jrok: In netbeans, I can't see any "GUI app" or "console app" option. @zeta: I added the code to a new project. Thanks :) Why both of you don't add the comments as "Answers" ? Then I can make one as "selected" and can give upvotes for both :) — PeakGen

@zeta: Please submit your comment as an answer. Then I can accept it and mark this topic as solved :) — PeakGen

The only specific message in there says

ClassWithPara.cpp:28:4: warning: no newline at end of file mkdir -p

Have you tried adding a newline at the end of that file?

(Technically it's required, although that's not always enforced.) It's unclear from the output you give whether that really is just a warning or if it's being treated as an error.
