在Vscode中使用gdb调试程序
在Vscode中使用gdb调试程序
- 1 创建launch.json文件
-
- l a u n c h . j s o n \textcolor{red}{launch.json} launch.json
- 2 创建tasks.json文件
-
- t a s k s . j s o n \textcolor {red} {tasks.json} tasks.json
-
详情参考官方文档
set(CMAKE_BUILD_TYPE Debug) # 首先要在CMakeList.txt中设置dubug模式
1 创建launch.json文件
l a u n c h . j s o n \textcolor{red}{launch.json} launch.json
调试多个程序和调试一个程序是一样的道理，只需要后面把两个文件compounds

2 创建tasks.json文件
t a s k s . j s o n \textcolor {red} {tasks.json} tasks.json
这个文件是通用的，直接复制粘贴即可。这个文件主要为了编译代码，所以如果不对代码修改，其实也可以不加这个文件。
