Not able to run simple OpenGL program in Linux Minut

I'm learning OpenGL on Mac, where it works fine and I'm trying to recreate my programs on Linux Mint 17.3 in a VirtualBox virtual machine.

I am told I only need g++, make, freeglut3-dev and a text editor and I believe I already have all of these. If I do sudo apt-get install g++ for example, it will say g++ is already the newest version and it is the same for the rest as well.

I've written a simple program:

#include <GL/freeglut.h>
#include <GL/gl.h>

void renderFunction() {
    glClearColor(0.0, 0.0, 0.0, 0.0);
    glClear(GL_COLOR_BUFFER_BIT);
    glColor3f(1.0, 1.0, 1.0);
    glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);
    glBegin(GL_POLYGON);
    glVertex2f(-0.5, -0.5);
    glVertex2f(-0.5, 0.5);
    glVertex2f(0.5, 0.5);
    glVertex2f(0.5, -0.5);
    glEnd();
    glFlush();
}

int main(int argc, char** argv) {
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_SINGLE);
    glutInitWindowSize(500,500);
    glutInitWindowPosition(100,100);
    glutCreateWindow("OpenGL - First window demo");
    glutDisplayFunc(renderFunction);
    glutMainLoop();  

return 0;
}

The compile command g++ opengl.c -lglut -lGL -lGLEW -lGLU -o opengl seems to work. But when I run ./opengl I get a massive error message:

I have no idea what any of this means or how to deal with it.

OpenGL relies on graphics drivers. VirtualBox does not have the most up-to-date, working drivers. Best you can do is install guest additions. Freeglut isn't helping either, most promising would be to write the minimal code needed by hand only using glad and GLFW. But don't expect much and certainly not "testing the portability of my program".

I once managed to get OpenGL 3.3 working on a particular version of Ubuntu with some experimental mesa drivers after a few tries, but I have no idea how to reliably reproduce that. Almost the same question on askubuntu.
