Why doesn't my OpenGL work? - visual-studio

Question

I was trying out openGL with SDL for the first time in Visual Studio 2013.
SDL worked fine, but I somehow don't get how I should set up my project so that I can use openGL.
I included 'openGL32.lib' in my linker input, have a #include to the "GL\gl.h" header, but I get a compilation error, and the errors seem to be in the gl.h I included. Here is the code:
#include <stdio.h>
#include <stdlib.h>
/* If using gl3.h */
/* Ensure we are using opengl's core profile only */
#define GL3_PROTOTYPES 1
#include <C:\Program Files\Microsoft SDKs\Windows\v7.1A\Include\gl\gl.h>
#include <SDL.h>
#define PROGRAM_NAME "Tutorial1"
/* A simple function that prints a message, the error code returned by SDL,
* and quits the application */
void sdldie(const char *msg)
{
printf("%s: %s\n", msg, SDL_GetError());
SDL_Quit();
exit(1);
}
void checkSDLError(int line = -1)
{
#ifndef NDEBUG
const char *error = SDL_GetError();
if (*error != '\0')
{
printf("SDL Error: %s\n", error);
if (line != -1)
printf(" + line: %i\n", line);
SDL_ClearError();
}
#endif
}
/* Our program's entry point */
int main(int argc, char *argv[])
{
SDL_Window *mainwindow; /* Our window handle */
SDL_GLContext maincontext; /* Our opengl context handle */
if (SDL_Init(SDL_INIT_VIDEO) < 0) /* Initialize SDL's Video subsystem */
sdldie("Unable to initialize SDL"); /* Or die on error */
/* Request opengl 3.2 context.
* SDL doesn't have the ability to choose which profile at this time of writing,
* but it should default to the core profile */
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 2);
/* Turn on double buffering with a 24bit Z buffer.
* You may need to change this to 16 or 32 for your system */
SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 24);
/* Create our window centered at 512x512 resolution */
mainwindow = SDL_CreateWindow(PROGRAM_NAME, SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,
512, 512, SDL_WINDOW_OPENGL | SDL_WINDOW_SHOWN);
if (!mainwindow) /* Die if creation failed */
sdldie("Unable to create window");
checkSDLError(__LINE__);
/* Create our opengl context and attach it to our window */
maincontext = SDL_GL_CreateContext(mainwindow);
checkSDLError(__LINE__);
/* This makes our buffer swap syncronized with the monitor's vertical refresh */
SDL_GL_SetSwapInterval(1);
/* Clear our buffer with a red background */
glClearColor(1.0, 0.0, 0.0, 1.0);
glClear(GL_COLOR_BUFFER_BIT);
/* Swap our back buffer to the front */
SDL_GL_SwapWindow(mainwindow);
/* Wait 2 seconds */
SDL_Delay(2000);
/* Same as above, but green */
glClearColor(0.0, 1.0, 0.0, 1.0);
glClear(GL_COLOR_BUFFER_BIT);
SDL_GL_SwapWindow(mainwindow);
SDL_Delay(2000);
/* Same as above, but blue */
glClearColor(0.0, 0.0, 1.0, 1.0);
glClear(GL_COLOR_BUFFER_BIT);
SDL_GL_SwapWindow(mainwindow);
SDL_Delay(2000);
/* Delete our opengl context, destroy our window, and shutdown SDL */
SDL_GL_DeleteContext(maincontext);
SDL_DestroyWindow(mainwindow);
SDL_Quit();
return 0;
}
And this is the error I get:
