Im new to open gl, and im having some troubles:

when i try to run this code:

Code:
Code:
#pragma comment(linker, "/subsystem:windows")
/*	Pre-processor directives*/
#include <windows.h>
/*	Windows Procedure Event Handler*/
LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
	PAINTSTRUCT paintStruct;
	/*	Device Context*/
	HDC hDC; 
	/*	Text for display*/
	char string[] = "Hello, World!"; 
	/*	Switch message, condition that is met will execute*/
	switch(message)
	{
		/*	Window is being created*/
		case WM_CREATE: 
			return 0;
			break;
		/*	Window is closing*/
		case WM_CLOSE: 
			PostQuitMessage(0);
			return 0;
			break;
		/*	Window needs update*/
		case WM_PAINT: 
			hDC = BeginPaint(hwnd,&paintStruct);
			/*	Set txt color to blue*/
			SetTextColor(hDC, COLORREF(0x00FF0000));
			/*	Display text in middle of window*/
			TextOut(hDC,150,150,string,sizeof(string)-1);
			EndPaint(hwnd, &paintStruct);
			return 0;
			break;
		default:
			break;
	}
	return (DefWindowProc(hwnd,message,wParam,lParam));
}
/*	Main function*/
int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
{
	WNDCLASSEX  windowClass;		//window class
	HWND		hwnd;				//window handle
	MSG			msg;				//message
	bool		done;				//flag saying when app is complete
	/*	Fill out the window class structure*/
	windowClass.cbSize = sizeof(WNDCLASSEX);
	windowClass.style = CS_HREDRAW | CS_VREDRAW;
	windowClass.lpfnWndProc = WndProc;
	windowClass.cbClsExtra = 0;
	windowClass.cbWndExtra = 0;
	windowClass.hInstance = hInstance;
	windowClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
	windowClass.hCursor = LoadCursor(NULL, IDC_ARROW);
	windowClass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
	windowClass.lpszMenuName = NULL;
	windowClass.lpszClassName = "MyClass";
	windowClass.hIconSm = LoadIcon(NULL, IDI_WINLOGO);
	/*	Register window class*/
	if (!RegisterClassEx(&windowClass))
	{
		return 0;
	}
	/*	Class registerd, so now create window*/
	hwnd = CreateWindowEx(NULL,		//extended style
		"MyClass",			//class name
		"A Real Win App",		//app name
		WS_OVERLAPPEDWINDOW |		//window style
		WS_VISIBLE |
		WS_SYSMENU,
		100,100,			//x/y coords
		400,400,			//width,height
		NULL,				//handle to parent
		NULL,				//handle to menu
		hInstance,			//application instance
		NULL);				//no extra parameter's
	/*	Check if window creation failed*/
	if (!hwnd)
		return 0;
	done = false; //initialize loop condition variable
	/*	main message loop*/
	while(!done)
	{
		PeekMessage(&msg,hwnd,NULL,NULL,PM_REMOVE);
		if (msg.message == WM_QUIT) //check for a quit message
		{
			done = true; //if found, quit app
		}
		else
		{
			/*	Translate and dispatch to event queue*/
			TranslateMessage(&msg); 
			DispatchMessage(&msg);
		}
	}
	return msg.wParam;
}
Ive been searching for other posts regarding this problem, but what i found told me to delete the #include "stdafx.h" line, but when i delete this line i get these errors:
undefined reference to `_SetTextColor@8'
undefined reference to `GetStockObject@4'
undefined reference to `TextOutA@20'

How can i solve this 'undefined reference to `_SetTextColor@8'
problem??

PS> I'm a newbie, using Eclipse IDE and MINGW/MSYS toolchain.
