OpenGL GLut compiling issues

Question

hi im doing an openGL project but after downloading and installing the glut library files it still wont compile and i get 12 error C3861: identifier not found, any help would be great

#include <windows.h>
#include <gl/gl.h>

void init(void);
void display(void);
void keyboard(unsigned char, int, int);
void resize(int, int);

int is_depth;

int main(int argc, char **argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB);
    glutInitWindowSize(600, 600);
    glutInitWindowPosition(40, 40);
    glutCreateWindow("3D World");
    init();
    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard);
    glutReshapeFunc(resize);

    glutMainLoop();

    return 0;

}

void init(void)
{
    glClearColor(0.0, 0.0, 0.0, 0.0);
    glEnable(GL_DEPTH_TEST);
    is_depth = 1;
    glMatrixMode(GL_MODELVIEW);

}

void display(void)
{
    if (is_depth)
        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    else
        glClear(GL_COLOR_BUFFER_BIT);

    glBegin(GL_QUADS);
        glColor3f(0.2f, 0.2f, 0.2f);
        glVertex3f(-100.0, 0.0, -100.0);
        glColor3f(0.4f, 0.4f, 0.4f);
        glVertex3f(-100.0, 0.0, 100.0);
        glColor3f(0.6f, 0.6f, 0.6f);
        glVertex3f(100.0, 0.0, 100.0);
        glColor3f(0.8f, 0.8f, 0.8f);
            glVertex3f(100.0, 0.0, -100.0);     
    glEnd();

}

void keyboard(unsigned char key, int x, int y)
{
    switch (key)
    {
    case 'a':
        glTranslatef(5.0, 0.0, 0.0);
        break;

    case 'd':
        glTranslatef(-5.0, 0.0, 0.0);
        break;

    case 's':
        glTranslatef(0.0, 0.0, -5.0);
        break;

    case 'w':
        glTranslatef(0.0, 0.0, 5.0);
        break;

    }

    display();

}

void resize(int width, int height)
{
    if(height == 0) height = 1;

    glMatrixMode(GL_PROJECTION);

    glLoadIdentity();

    gluPerspective(45.0, width / height, 1.0, 400.0);

    glTranslatef(0.0, -5.0, -150.0);

    glMatrixMode(GL_MODELVIEW);
}

and my errors are

the glut32.dll file is in my system32 folder

my glut.h file is in C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include

and my glut.lib file is in C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib

UPDATE added and now i have these errors

Answer 1

This problem resulted from wrong .lib linking.

In Project's properites, choose: Configuration properties -> linker -> input

in the right column choose: additional dependencies, add following libraries to the list, seperated by semi colon: opengl32.lib ; glut32.lib ; glu32.lib ;

This will solve the problem.
