VScode+SDL2配置教程
前天我想找一个图形库写个小工具,想找个小巧一点的图形库,于是就找到了ege(easy graphics engine),花了点时间配置到了vscode上,顺便写了个文章,这是教程地址:https://blog.csdn.net/qq272508839/article/details/104287255
今天想起一个比较知名的图形库叫SDL,很早之前就听过,于是我就下载了一个打算试试,是在MinGW环境下的,具体配置MinGW的方法我就不说了,很简单。
先到官网:http://www.libsdl.org/下载两个东西,如下图:
对应自己的平台下载,我是win10 64位。
下载完是这俩东西:
509kb那个是用来编译完之后放到exe同级目录的,下面那个tar是需要自己安装的部分。
解压tar.gz,里面有这么几个文件夹:
标出的这俩文件夹是需要放到MinGW安装目录里的,不是俩都要复制,对应自己的MinGW版本复制一个就好,我是64位MinGW,我就要x86_64开头的那个了。
打开x86_64开头的文件夹,里面有几个文件夹(bin、include、lib、share):
把这几个文件夹全部选中,复制到MinGW安装目录里面\x86_64-w64-mingw32目录中,要是32位的MinGW呢就是MinGW安装目录里面\i686-w64-mingw32,复制完了之后会发现下图中的目录里多出一个SDL2,这就说明安装完成了:
然后就是配置vscode了,新建一个工程文件夹,在工程根目录新建.vscode目录(vscode前一个点别忘了),在.vscode目录里新建3个json文件:tasks.json、launch.json、c_cpp_properties.json,然后把509kb那个压缩包解压出一个文件叫SDL2.dll,把这个dll复制到exe同级目录,在根目录下建一个main.c,如下图:
然后就是复制代码粘贴到对应的文件里了,直接上代码。

main.c
#include <SDL2/SDL.h>
SDL_Window *window = NULL;
SDL_Surface *surface = NULL;
//main函数中的参数不能省略,不然会报错
int main(int args, char *argv[])
{
SDL_Init(SDL_INIT_VIDEO);
window = SDL_CreateWindow("SDL2 Test", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 800, 600, SDL_WINDOW_SHOWN);
if (!window)
return -1;
surface = SDL_GetWindowSurface(window);
if (!surface)
return -2;
SDL_Rect rec;
rec.x = 700;
rec.y = 10,
rec.w = 20;
rec.h = 20;
while (1)
{
SDL_FillRect(surface, &rec, SDL_MapRGB(surface->format, 180, 10, 140));
rec.x += 6;
rec.y += 2;
rec.x = rec.x > 800 ? 0 : rec.x;
rec.y = rec.y > 600 ? 0 : rec.y;
SDL_FillRect(surface, &rec, SDL_MapRGB(surface->format, 10, 200, 120));
SDL_UpdateWindowSurface(window);
SDL_Delay((1.0 / 60) * 1000);
}
SDL_FreeSurface(surface);
SDL_DestroyWindow(window);
SDL_Quit();
return 0;
}
大功告成,按Ctrl+Shift+B编译,得到main.exe,双击运行:
