环境：

OS：centos 7.9.2009 Minimal(无界面版本)
cmake: 2.8.12
编译器：g++ 4.8.5
调试器：gdb 4.8.5
code-server: v4.0.2(vscode v1.63.0)
code-server插件：ms-vscode.cpptools-1.9.0@linux-x64.vsixtwxs.cmake-0.0.17.vsixms-vscode.cmake-tools-1.9.2.vsix

前言

linux下使用gdb调试程序是一个基本操作。

本文介绍使用code-server + gdb离线远程web浏览器调试C++的cmake工程。

最终效果：可以在没有GUI界面的centos上，在windows/linux等上以浏览器的方式调试centos上的C++程序。

1. 下载和安装code-server

wget https://github.com/coder/code-server/releases/download/v4.0.2/code-server-4.0.2-amd64.rpm

镜像加速

wget https://ghproxy.com/https://github.com/coder/code-server/releases/download/v4.0.2/code-server-4.0.2-amd64.rpm

安装

sudo yum -ivh code-server-4.0.2-amd64.rpm

2. 编写测试程序

目录结构：

$ tree
.
+--- .vscode
|   +--- launch.json
+--- CMakeLists.txt
+--- myprint.cpp
+--- myprint.h
+--- test.cpp

test.cpp

#include "myprint.h"
int main()
{int num = 1;myprintf(num);return 0;
}

myprint.h

void myprintf(int num);

myprint.cpp

#include <iostream>
void myprintf(int num)
{std::cout << "num: " << num << std::endl;
}

CMakeLists.txt

cmake_minimum_required(VERSION 2.8.12)project(test)include_directories(.)add_executable(${PROJECT_NAME} test.cpp myprint.cpp)

3. 编译源码

注意：必须生成Debug模式，否则无法调试

mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Debug
cmake --build . --config Debug

建议使用CMake Tools进行编译。

注意：离线下需要同时下载CMake和CMake Tools

$ code-server --install-extension twxs.cmake-0.0.17.vsix
Installing extensions...
Extension 'twxs.cmake-0.0.17.vsix' was successfully installed.
$ code-server --install-extension ms-vscode.cmake-tools-1.9.2.vsix
Installing extensions...
Extension 'ms-vscode.cmake-tools-1.9.2.vsix' was successfully installed.

linux下验证应用程序是否为debug版本：

readelf -S test | grep debug

4. 运行code-server

运行

默认使用配置文件：~/.config/code-server/config.yaml

code-server

设置密码

export PASSWORD="123456" && code-server --bind-addr 0.0.0.0:8080

不设置密码

code-server --auth=none --bind-addr 0.0.0.0:8080

使用

浏览器中输入http://IP:8080即可访问

5. code-server配置C++调试环境

安装C++插件

安装C++调试插件 C/C++ extension for VS Code

$ code-server --install-extension ms-vscode.cpptools-1.9.0@linux-x64.vsix
Installing extensions...
Extension 'ms-vscode.cpptools-1.9.0@linux-x64.vsix' was successfully installed.

安装cmake插件【可选，便于编译】

安装cmake插件 CMake Tools

注意：离线下需要同时下载CMake和CMake Tools

创建调试启动文件

【Run(Ctrl + Shift + D)】-> 【create a launch.json file】-> 【C++ (GDB/LLDB)】

launch.json

{"version": "0.2.0","configurations": [{"name": "(gdb) 启动","type": "cppdbg","request": "launch","program": "${workspaceFolder}/build/test","args": [],"stopAtEntry": false,"cwd": "${workspaceFolder}","environment": [],"externalConsole": false,"MIMode": "gdb","setupCommands": [{"description": "为 gdb 启用整齐打印","text": "-enable-pretty-printing","ignoreFailures": true}]}]
}

6. 调试

设置断点，在code-server中按F5进行调试。

code-server左侧有变量、监视、调用堆栈、断点和Modules信息。
