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),花了点时间配置到了上,顺便写了个文章,这是教程地址:
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: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,我就要开头的那个了 。
打开开头的文件夹,里面有几个文件夹(bin、、lib、share):
把这几个文件夹全部选中,复制到MinGW安装目录里面\-w64-目录中,要是32位的MinGW呢就是MinGW安装目录里面\i686-w64-,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:
【VScode+SDL2配置教程】然后就是配置了,新建一个工程文件夹,在工程根目录新建.目录(前一个点别忘了),在.目录里新建3个json文件:tasks.json、.json、.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 。
