在 vscode 中运行时无法暂停或设置断点答案

【问题标题】：Can't pause or set breakpoint when running in vscode在 vscode 中运行时无法暂停或设置断点

【问题描述】：

我目前正在使用 Qemu for i368 开发一个（简单的）内核。我使用的是普通的 makefile 并通过 GDB 调试到 Qemu 工作完美我搬到了 CMake，由于某种原因，我只能在我的代码已经在断点中时才能打断点。

我也不能暂停，我从调试窗口得到的反馈是暂停成功设置断点时它告诉我尝试绑定断点

提示可能是，当我停止调试会话时，我会从 vscode 弹出一个提示超时

我的启动.json

            "text": "-enable-pretty-printing",
            "ignoreFailures": true
        }
    ],

}
]

}

暂停响应

<--   C (pause-67): {"command":"pause","arguments":{"threadId":1},"type":"request","seq":67}
--> R (pause-67): {"type":"response","request_seq":67,"success":true,"command":"pause","body":{},"seq":1321}

设置断点时的响应：

--> E (output): {"type":"event","event":"output","body":{"category":"console","output":"1: (340258) Send Event AD7BreakpointErrorEvent\n"},"seq":1327}
1: (340258) Send Event AD7BreakpointErrorEvent
--> R (setBreakpoints-69): {"type":"response","request_seq":69,"success":true,"command":"setBreakpoints","body":{"breakpoints":[{"id":4,"verified":true,"line":73}]},"seq":1329}
--> E (breakpoint): {"type":"event","event":"breakpoint","body":{"reason":"changed","breakpoint":{"id":4,"verified":false,"message":"Attempting to bind the breakpoint....","line":73}},"seq":1331}

如果我在 Qemu 终端中输入 stop，vscode 就会停止，我可以再次设置断点。

【问题讨论】：

您是否使用debug 标志编译内核？
是的 - 通过构建发布/调试检查了这一点，我看到调试版本大约大了 60%。我也做了文件它说它没有被删除调试符号

【解决方案1】：

我遇到了类似的问题，尝试使用选项 ""MIDebuggerServerAddress": "targetIp:port" 连接远程目标，而不是 customLaunchSetupCommands 中的命令。

【解决方案2】：

我有同样的问题，但还没有解决。但我发现了一些可能对你有用的东西。根据他们在这个问题下的讨论：https://github.com/Microsoft/vscode-cpptools/issues/833 你可以试试

将调试器的 target-async 设置为关闭：

    "setupCommands": [
    {
    "text": "set target-async off"
    }

向本地调试器进程发送 SIGINT

    -exec -interpreter-exec console "signal 2"

看看它是否可以暂停。
