vscode C++远程调试运行(学习C++用)
作者:兰彻斯特
目标:
连接远程主机 (ssh)
配置C++编译环境 (输出结果后删除二进制文件)
步骤:
安装Remote SSH,连接远程主机
Visual Studio 官方文档
https://code.visualstudio.com/docs/remote/ssh
图标
2. 配置C++编译运行环境
主要参考下面两篇文档
https://code.visualstudio.com/docs/cpp/config-wsl
https://code.visualstudio.com/docs/editor/tasks
2.1 新建一个C++源文件HelloWorld.cpp(测试用)
#include <iostream> int main(){ std::cout<<"Hello World!\n"; return 0; }
2.2 安装 Microsoft C/C++插件
注意安装到远程主机上
2.3 创建tasks.json文件
从菜单栏选择Terminal>Configure Default Build Task, 在下拉栏里选择C/C++: g++ build active file. 这会生成tasks.json文件。
按需修改tasks.json文件:
{ "tasks": [ { //编译源文件 "type": "shell", "label": "g++ build active file", "command": "/usr/bin/g++", "args": [ "-std=c++11", //C++版本, 可不加 "-g", "${file}", "-o", "${fileDirname}/${fileBasenameNoExtension}" ], "options": { "cwd": "/usr/bin" }, "problemMatcher": [ "$gcc" ], "group": { "kind": "build", "isDefault": true } }, { //删除二进制文件 "type": "shell", "label": "delete output file", "command": "rm", "args": [ "${fileDirname}/${fileBasenameNoExtension}" ], "presentation": { "reveal": "silent", //删除过程不切换终端(专注程序输出) } } ], "version": "2.0.0" }
2.4 创建launch.json用于调试运行
在菜单栏选择Debug>Add Configuration, 选择C++ (GDB/LLDB), 在下拉栏中选择g++ build and debug active file.
这会创建launch.json, 编辑如下
{ "version": "0.2.0", "configurations": [ { "name": "g++ build and debug active file", "type": "cppdbg", "request": "launch", "program": "${fileDirname}/${fileBasenameNoExtension}", "args": [], "stopAtEntry": false, "cwd": "${workspaceFolder}", "environment": [], "externalConsole": false, "MIMode": "gdb", "setupCommands": [ { "description": "Enable pretty-printing for gdb", "text": "-enable-pretty-printing", "ignoreFailures": true } ], "preLaunchTask": "g++ build active file", "postDebugTask": "delete output file", "miDebuggerPath": "/usr/bin/gdb" } ] }
注:这里“preLaunchTask”调用tasks.json文件里定义的“g++ build and debug active file”任务, “postDebugTask”调用“delete output file”任务用来在程序运行结束后删除二进制文件。
2.5 调试F5, 不调试直接运行Cltr+F5
