Setting up Eclipse for C++ OpenGL development on Arch (Help, please!)

Question

I've recently switched over to Arch (and love it) from Windows 7, and am trying to start developing in OpenGL using C++. I've used Eclipse a lot on the Windows side for Java development, but I'm having trouble referencing the OpenGL libraries in the C++ stuff.
My code is as follows:
#include <GL/gl.h>
#include <GL/freeglut.h>
int main(int argc, char **argv) {
glutInit(&argc, argv);
return 0;
I don't believe the problem's there because the code won't even begin to compile.
I tried to find and select the libraries I need in the project properties, but I really have no idea what I'm doing in there. In the current state of things, this is my console output:
**** Build of configuration Debug for project CGame ****
make all
Building target: CGame
Invoking: Cross G++ Linker
g++ -L/usr/include/GL -o "CGame" ./main.o -l/usr/include/GL
/usr/bin/ld: cannot find -l/usr/include/GL
collect2: error: ld returned 1 exit status
make: *** [CGame] Error 1
**** Build Finished ****
This is what some parts of Eclipse's configuration look like:
Can anybody lend me a hand? I've been searching around on the Internet for a little while now, but I'm getting tired of all the shitty information there is. Many thanks if you can point out how to include the OpenGL/freeglut libraries in my project. If you want to see how my Eclipse stuff is configured, I can show you over Skype or TeamViewer.

Got it working? Great!
Personally, I use the GLFW window library for OpenGL coding. You can get it by:
pacman -S glfw
triangle.cpp
//========================================================================
// This is a small test application for GLFW.
// The program opens a window (640x480), and renders a spinning colored
// triangle (it is controlled with both the GLFW timer and the mouse).
//========================================================================
#include <stdio.h>
#include <stdlib.h>
#include <GL/glfw.h>
int main( void )
int width, height, x;
double t;
// Initialise GLFW
if( !glfwInit() )
fprintf( stderr, "Failed to initialize GLFW\n" );
exit( EXIT_FAILURE );
// Open a window and create its OpenGL context
if( !glfwOpenWindow( 640, 480, 0,0,0,0, 0,0, GLFW_WINDOW ) )
fprintf( stderr, "Failed to open GLFW window\n" );
glfwTerminate();
exit( EXIT_FAILURE );
glfwSetWindowTitle( "Spinning Triangle" );
// Ensure we can capture the escape key being pressed below
glfwEnable( GLFW_STICKY_KEYS );
// Enable vertical sync (on cards that support it)
glfwSwapInterval( 1 );
do
t = glfwGetTime();
glfwGetMousePos( &x, NULL );
// Get window size (may be different than the requested size)
glfwGetWindowSize( &width, &height );
// Special case: avoid division by zero below
height = height > 0 ? height : 1;
glViewport( 0, 0, width, height );
// Clear color buffer to black
glClearColor( 0.0f, 0.0f, 0.0f, 0.0f );
glClear( GL_COLOR_BUFFER_BIT );
// Select and setup the projection matrix
glMatrixMode( GL_PROJECTION );
glLoadIdentity();
gluPerspective( 65.0f, (GLfloat)width/(GLfloat)height, 1.0f, 100.0f );
// Select and setup the modelview matrix
glMatrixMode( GL_MODELVIEW );
glLoadIdentity();
gluLookAt( 0.0f, 1.0f, 0.0f, // Eye-position
0.0f, 20.0f, 0.0f, // View-point
0.0f, 0.0f, 1.0f ); // Up-vector
// Draw a rotating colorful triangle
glTranslatef( 0.0f, 14.0f, 0.0f );
glRotatef( 0.3f*(GLfloat)x + (GLfloat)t*100.0f, 0.0f, 0.0f, 1.0f );
glBegin( GL_TRIANGLES );
glColor3f( 1.0f, 0.0f, 0.0f );
glVertex3f( -5.0f, 0.0f, -4.0f );
glColor3f( 0.0f, 1.0f, 0.0f );
glVertex3f( 5.0f, 0.0f, -4.0f );
glColor3f( 0.0f, 0.0f, 1.0f );
glVertex3f( 0.0f, 0.0f, 6.0f );
glEnd();
// Swap buffers
glfwSwapBuffers();
} // Check if the ESC key was pressed or the window was closed
while( glfwGetKey( GLFW_KEY_ESC ) != GLFW_PRESS &&
glfwGetWindowParam( GLFW_OPENED ) );
// Close OpenGL window and terminate GLFW
glfwTerminate();
exit( EXIT_SUCCESS );
Then you can compile the code above by:
g++ triangle.cpp -o triangle -l GLFW -l GL
It just draws a rotating triangle, but should get you started on something more exiting.
