Simple OpenGL code always causes a segmentation error (C ++ on Ubuntu, virtual machine)

I just started trying to use OpenGL in C ++ for a class (I used it enough in Java before). And I started by trying to write something substantial, I could not get it to stop Seg, so I wrote this little piece of code, which is almost a line to translate the line from the example in the first chapter of the red book. This is also Seg. My question is why. I tried both eclipse and netbeans, I have a glut.h library linked in my projects in both, I run 64-bit ubuntu 10.4, in a virtual machine using VMWare, gcc and freeglut are both installed, Both netbeans and eclipse will be run regular (non-OpenGL) C ++ code, which I write without seg crashes.

Anyway, here is the code:

#include <stdlib.h>
#include <GL/freeglut.h>
#include <stdio.h>

void init(){
    glClearColor(0.0, 0.0, 0.0, 0.0);
    glMatrixMode(GL_PROJECTION);
    glLoadIdentity();
    glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);

}
void display(){
    glClear(GL_COLOR_BUFFER_BIT);
    glColor3f(1.0,1.0,1.0);
    glBegin(GL_POLYGON);
        glVertex3f(0.25, 0.25, 0.0);
        glVertex3f(0.75,0.25,0.0);
        glVertex3f(0.75,0.75, 0.0);
        glVertex3f(0.25, 0.75, 0.0);
        glEnd();
    glFlush();
}
int main(int argc, char** argv) {
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
    glutInitWindowSize(250,250);    //if I comment out this line,
    glutInitWindowPosition(100,100);
    glutCreateWindow(argv[0]);  //this line,
    init();  //this line and the glut main loop line it runs without any errors, but why wouldn't it? It not doing anything now!
    glutDisplayFunc(display);
    glutMainLoop();    //if I comment out just this line I get illegal instruction instead of segfault but I need this line
    return 0;
}
