SDL 2.0 如何在 windows 上使用？

// ConsoleSDL2.0.cpp : 定义控制台应用程序的入口点。

//

#include "stdafx.h"

#include <stdio.h>

#include <iostream>

#include <string>

#define SDL_MAIN_HANDLED

#include "SDL.h"

#pragma comment(lib,"SDL2.lib")

int main()

{

	//不使用 SDL_main(int argc, char *argv[]) 入口，需要调用下面一句函数，不然 SDL_Init 函数会调用失败，具体可官网查看 https://wiki.libsdl.org/CategoryInit

	//当然你也可以把主函数声明成和 SDL_main 一样的格式,就需要要定义 SDL_MAIN_HANDLED 宏了

	SDL_SetMainReady();

	//初始化

	if (SDL_Init(SDL_INIT_VIDEO) != 0)

	{

		SDL_Log("Unable to initialize SDL: %s", SDL_GetError());

		return 1;

	}

	SDL_Window *window = NULL;

	//创建窗体

	window = SDL_CreateWindow(

		"An SDL2 window",                  // window title

		SDL_WINDOWPOS_UNDEFINED,           // initial x position

		SDL_WINDOWPOS_UNDEFINED,           // initial y position

		640,                               // width, in pixels

		480,                               // height, in pixels

		SDL_WINDOW_OPENGL                  // flags - see below

	);

	if (window == NULL) {

		// In the case that the window could not be made...

		SDL_Log("Could not create window: %s\n", SDL_GetError());

		return -1;

	}

	SDL_Renderer *ren = nullptr;

	//创建渲染器

	ren = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);

	if (ren == nullptr)

	{

		std::cout << SDL_GetError() << std::endl;

		return 1;

	}

	SDL_Surface *bmp = nullptr;

	//加载图像到内存

	bmp = SDL_LoadBMP("xxx.bmp");

	if (bmp == nullptr)

	{

		std::cout << SDL_GetError() << std::endl;

		return 1;

	}

	SDL_Texture *tex = nullptr;

	tex = SDL_CreateTextureFromSurface(ren, bmp);

	//释放 SDL_Surface

	SDL_FreeSurface(bmp);

	//清空渲染器

	SDL_RenderClear(ren);

	//复制 SDL_Texture

	SDL_RenderCopy(ren, tex, NULL, NULL);

	//画线

	SDL_RenderDrawLine(ren, 0, 60, 120, 240);

	//更新渲染器

	SDL_RenderPresent(ren);

	while (true)

	{

	}

	//SDL_Delay(3000);

	//销毁指针

	SDL_DestroyTexture(tex);

	SDL_DestroyRenderer(ren);

	SDL_DestroyWindow(window);

	//退出

	SDL_Quit();

	//system("pause");

    return 0;
