VScode调试C语言

好些天前做的, 记不住全部步骤了😅, 如前面的步骤不通, 再baidu一下吧😅
环境是win10.

步骤

1. 下载mingw64_posix并解压;
2. Vscode安装C/C++插件; 其他插件包括code runner, 我不确定是不是一定需要;
3. 嵌入式插件可选, 包括keil assistant, PlatformIO IDE.
4. 最重要的是要在代码根目录下建立.vscode的文件夹, 里面放四个文件(这几个保证正确)
5. 非常重要, 编译器和调试器gcc.exe gdb.exe需要在vscode的终端中可以访问,即所在目录需要预先加入系统path. 否则编译会一直报错, 而且错误提示总让你以为是你的代码问题. 这一点我也很奇怪, json中已经有了编译器和调试器的配置为何再次需要.

里面的mingw64_posix路径根据实际情况修改

tasks.json

这个文件中的args就是gcc的args, 需要根据情况修改. 类似简单的makefile了.
多文件编译的时候, 这儿需要把需要编译的其他文件放进来.
需要编译引入预定义#define的时候, 加入-D预定义名
