[Dev C++] First Test to OpenGL, error found...

Hey OpenGL Programmers and C++ Users…

I am new with OpenGL and this OpenGL Forum yet…

So i use Dev C++ and i get installed FreeGLUT on Windows XP (at home i work on windows 7 and 10)…
Now i try if opengl works on Dev C++, but no… i get an error!..

Just this is my script copied from google yet…

#include <GL/glut.h>

void displayMe(void)
{
    glClear(GL_COLOR_BUFFER_BIT);
    glBegin(GL_POLYGON);
        glVertex3f(0.0, 0.0, 0.0);
        glVertex3f(0.5, 0.0, 0.0);
        glVertex3f(0.5, 0.5, 0.0);
        glVertex3f(0.0, 0.5, 0.0);
    glEnd();
    glFlush();
}

int main(int argc, char** argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_SINGLE);
    glutInitWindowSize(300, 300);
    glutInitWindowPosition(100, 100);
    glutCreateWindow("Hello world :D");
    glutDisplayFunc(displayMe);
    glutMainLoop();
    return 0;
}

Now i get an error in the returning function, so this is the error i get:

I am an newbie with OpenGL and i use Dev C++ for it…, Please can anyone help me to correct my code ?..
Thanks for help, Jamie.

Your link line is missing references to the GLUT and OpenGL libraries.

Try adding the arguments “-lglut32 -lopengl32”. If you still have unresolved “glut” symbols", try -lfreeglut instead of -lglut32.

For more possible solutions, websearch “devc++ glut unresolved reference”. For instance:
