VSCode在Linux和Windows调试C/C++程序

VSCode是一个文本编辑器，不具备编译功能，但是可以调用外部编译器调试器来实现调试功能 Linux 使用GDB，Windows 可以安装minGW， 写好测试文件main.cpp , 用vscode 打开代码所在文件夹，切换到调试界面，点击配置按钮 选择 C++(GDB/LLDB) for Windows or Linux 或者选择 C++(Windows) for Windows 弹出默认的launch.json文件，在此基础上修改 “program” ： 要调试运行的程序，修改为程序名，或 {file}.o / {file}.exe

根据当前系统在"linux"或者“Windows” 分别添加 gdb的安装路径

"miDebuggerPath": "/usr/bin/gdb",

或

"miDebuggerPath": "D:/MinGW/bin/gdb.exe",

下面多余的 C++ Attach项可以整个删除，也可忽略，修改好后的launch.json文件如下

//launch.json { "version": "0.2.0", "configurations": [ { "name": "C++ Launch", "type": "cppdbg", "request": "launch", "program": "${file}.o", "args": [], "cwd": "${workspaceRoot}", "environment": [], "externalConsole": true, "preLaunchTask": "g++", "linux": { "miDebuggerPath": "/usr/bin/gdb", "MIMode": "gdb", "setupCommands": [ { "description": "Enable pretty-printing for gdb", "text": "-enable-pretty-printing", "ignoreFailures": true } ] }, "osx": { "MIMode": "lldb" }, "windows": { "miDebuggerPath": "D:/MinGW/bin/gdb.exe", "MIMode": "gdb", "setupCommands": [ { "description": "Enable pretty-printing for gdb", "text": "-enable-pretty-printing", "ignoreFailures": true } ] } } ] }

然后点击调试按钮，提示 没有配置task runner，点击配置

选择Others或任一个，弹出默认tasks.json文件，用下面的文件覆盖原来的内容

//tasks.json { "version": "0.1.0", "command": "g++", "args": [ "-g", "${file}", "-o", "${file}.o" ], "problemMatcher": { "owner": "cpp", "fileLocation": [ "relative", "${workspaceRoot}" ], "pattern": { "regexp": "^(.*):(\\\\d+):(\\\\d+):\\\\s+(warning|error):\\\\s+(.*)$", "file": 1, "line": 2, "column": 3, "severity": 4, "message": 5 } } } command: gcc , g++

args: 编译参数

最后再次点调试按钮，即可成功运行调试，可以添加断点，查看变量，堆栈等常用调试功能
