Hey guys,
I just started to try and use OpenGL and I wanted to run an example but I get linker errors.
The code is just fine but it has linker errors says the console.
Linker Errors/Console:

[Linker error] undefined reference to `glFinish@0' 
  [Linker error] undefined reference to `wglSwapBuffers@4' 
  [Linker error] undefined reference to `wglSwapBuffers@4'
  [Linker error] undefined reference to `wglGetCurrentContext@0'

There's more but it would be too time consuming to copy and paste each line.

This is the OpenGL example:

#include <iostream>
#include <stdlib.h> //Needed for "exit" function

#include <GL/glut.h>

using namespace std;

//Called when a key is pressed
void handleKeypress(unsigned char key, //The key that was pressed
					int x, int y) {    //The current mouse coordinates
	switch (key) {
		case 27: //Escape key
			exit(0); //Exit the program

//Initializes 3D rendering
void initRendering() {
	//Makes 3D drawing work when something is in front of something else

//Called when the window is resized
void handleResize(int w, int h) {
	//Tell OpenGL how to convert from coordinates to pixel values
	glViewport(0, 0, w, h);
	glMatrixMode(GL_PROJECTION); //Switch to setting the camera perspective
	//Set the camera perspective
	glLoadIdentity(); //Reset the camera
	gluPerspective(45.0,                  //The camera angle
				   (double)w / (double)h, //The width-to-height ratio
				   1.0,                   //The near z clipping coordinate
				   200.0);                //The far z clipping coordinate

//Draws the 3D scene
void drawScene() {
	//Clear information from last draw
	glMatrixMode(GL_MODELVIEW); //Switch to the drawing perspective
	glLoadIdentity(); //Reset the drawing perspective
	glBegin(GL_QUADS); //Begin quadrilateral coordinates
	glVertex3f(-0.7f, -1.5f, -5.0f);
	glVertex3f(0.7f, -1.5f, -5.0f);
	glVertex3f(0.4f, -0.5f, -5.0f);
	glVertex3f(-0.4f, -0.5f, -5.0f);
	glEnd(); //End quadrilateral coordinates
	glBegin(GL_TRIANGLES); //Begin triangle coordinates
	glVertex3f(0.5f, 0.5f, -5.0f);
	glVertex3f(1.5f, 0.5f, -5.0f);
	glVertex3f(0.5f, 1.0f, -5.0f);
	glVertex3f(0.5f, 1.0f, -5.0f);
	glVertex3f(1.5f, 0.5f, -5.0f);
	glVertex3f(1.5f, 1.0f, -5.0f);
	glVertex3f(0.5f, 1.0f, -5.0f);
	glVertex3f(1.5f, 1.0f, -5.0f);
	glVertex3f(1.0f, 1.5f, -5.0f);
	glVertex3f(-0.5f, 0.5f, -5.0f);
	glVertex3f(-1.0f, 1.5f, -5.0f);
	glVertex3f(-1.5f, 0.5f, -5.0f);
	glEnd(); //End triangle coordinates
	glutSwapBuffers(); //Send the 3D scene to the screen

int main(int argc, char** argv) {
	//Initialize GLUT
	glutInit(&argc, argv);
	glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
	glutInitWindowSize(400, 400); //Set the window size
	//Create the window
	glutCreateWindow("Basic Shapes - videotutorialsrock.com");
	initRendering(); //Initialize rendering
	//Set handler functions for drawing, keypresses, and window resizes
	glutMainLoop(); //Start the main loop.  glutMainLoop doesn't return.
	return 0; //This line is never reached

I don't have any acquaintance with OGL but it seems glaux library is missing. See:

-lwinmm is missing?

It seems it was missing glaux.a but I still get some linker errors:

[Linker error] undefined reference to `joyReleaseCapture@4' 
  [Linker error] undefined reference to `joySetCapture@16' 
  [Linker error] undefined reference to `joyGetPosEx@8'   
[Linker error] undefined reference to `joyGetPosEx@8'

And that's it.

Yes! It worked!
Damn I love you!!
