新建一个文件夹lvgl_similator_vs2019，再在此文件目录下创建一个VS2019控制台工程

选择控制台应用，点击下一步

工程名输入lvgl_similator,路径选择到lvgl_similator_vs2019目录，最后点击创建

将下载好的SDL2-devel-2.0.12-VC.zip文件解压到lvgl_similator_vs2019\lvgl_similator目录下，并重命名为SDL2

在VS菜单中点击“项目”选项卡，选择“lvgl_similator属性”

在配置处选择“所有配置”，平台选择x64，引入SDL2中的include路径到C++附加包含目录中，加入$(ProjectDir)\SDL2\include内容

在配置属性中选择链接器的“输入”，编辑附加依赖项，在附加依赖项中添加SDL2的SDL2.lib和SDL2main.lib

在配置属性中选择链接器的“常规”，编辑附加库目录，在附加库目录中添加$(ProjectDir)\SDL2\lib\x64

将lvgl_similator_vs2019\lvgl_similator\SDL2\lib\x64目录下的SDL2.dll文件

复制到lvgl_similator_vs2019\lvgl_similator目录下

在lvgl_similator.cpp中加入以下代码

#include <iostream>#define SDL_MAIN_HANDLED#include <SDL.h>int main()
{if (SDL_Init(SDL_INIT_VIDEO) != 0){std::cout << "SDL_Init Error: " << SDL_GetError() << std::endl;return 1;}SDL_Quit();return 0;
}

编译并运行，如果没有错误提示，说明SDL2加入成功

以下是加入LVGL相关操作
将下载的lvgl,lvgl_drivers,lvgl_exmaples分别解压到lvgl_similator_vs2019\lvgl_similator目录下

在lvgl_similator工程下分别创建lvgl,lvgl_drivers,lvgl_exmaples项，并分别加入lvgl,lvgl_driver,lvgl_exmaples目录下所有文件到工程

将lvgl_similator_vs2019\lvgl_similator\lv_drivers目录下的lv_drv_conf_template.h文件复制到上一级目录，并重命名为

lv_drv_conf.h，将lvgl_similator_vs2019\lvgl_similator\lv_examples目录下的lv_ex_conf_template.h文件复制上一级目录，

并重命名为lv_ex_conf.h，将lvgl_similator_vs2019\lvgl_similator\lvgl目录下的lv_conf_template.h文件复制到上一级目录，

并重命名为lv_conf.h

分别将lv_conf.h,lv_drv_conf.h,lv_ex_conf.h中的#if 0 改成#if 1

将lvgl_similator.cpp中更换成以下内容
