如何使用vscode连接到远程gdb

我在这里找到了这个问题的答案：是否可以使用vscode连接到远程gdb目标？

摘要：

首先，您需要安装VS代码的本机调试扩展。

然后编辑launch.json文件并添加：

{
"type": "gdb",
"request": "attach",
"name": "Attach to gdbserver",
"executable": "<path to the elf/exe file relative to workspace root in order to load the symbols>",
"target": "X.X.X.X:9999",
"remote": true,
"cwd": "${workspaceRoot}", 
"gdbpath": "path/to/your/gdb",
"autorun": [
"any gdb commands to initiate your environment, if it is needed"
]
}

然后您可以重新启动VS代码并开始调试。请确保没有其他客户端连接到gdb服务器，否则会出现超时错误。

您必须在远程机器上安装gdbserver。例如

apt-get install gdbserver

在远程机器上启动gdbserver

gdbserver :1234 ./mybinary

选择您喜欢的任何端口-此处为1234

通过键入测试从本地机器到gdbserver的连接

gdb
(gdb) target remote myremotehostname:1234

触发任何gdb命令以检查它是否工作——例如c(或continue(以继续运行mybinary。

将以下内容放入.vscode/launch.json

{
"name": "C++ Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceRoot}/mybinary",
"miDebuggerServerAddress": "myremotehostname:1234",
"cwd": "${workspaceRoot}",
"externalConsole": true,
"linux": {
"MIMode": "gdb"
}
}

或者使用其他答案中给出的"type": "gdb"启动配置。

为了让代码浏览和工作，在本地和远程同步源目录是很重要的。使用网络文件系统、手动复制、git触发器或类似的东西来设置它。

这就是我的工作原理：

{
"version": "0.2.0",
"configurations": [{
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/vmlinux", // for loading symbols from running program
"cwd": "${workspaceFolder}",
// if you want to connect at entry point (requires remote program to start paused)
"stopAtEntry": true,
"stopAtConnect": true,
"MIMode": "gdb",
"miDebuggerPath": "/usr/bin/gdb",
"miDebuggerServerAddress": "localhost:1234",
"setupCommands": [{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true,
}]
}]
}
