c# - VSCode dbg 将本地进程附加到调试 C# dll 使用的 C dll

问题描述

我想quickfuncs.dll在 VSCode 中调试由 MinGW64 使用 -g （调试符号）编译的 C DLL 。此 DLL 由 C# DLL（也使用调试符号编译）使用，由以下人员运行： "C:\Program Files\dotnet\dotnet.exe" exec "D:\Server\bin\Debug\netcoreapp2.0\Server.dll" Parameter1=test

我已经launch.json根据https://github.com/Microsoft/vscode-cpptools/blob/master/launch.md进行了配置

    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Attach to process",
            "type": "cppdbg",
            "request": "attach",
            "program": "C:/Program Files/dotnet/dotnet.exe",
            "processId": "${command:pickProcess}",
            "MIMode": "gdb",
            "miDebuggerPath": "c:/msys2/mingw64/bin/gdb.exe",
            "targetArchitecture": "x64",
            "additionalSOLibSearchPath": "${workspaceFolder}/bin/Debug/win64/;d:\\Server\\src\\Server\\WorkingDirectory\\",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": false,
                }
            ],
            "logging": { 
                "trace": true, 
                "traceResponse": true
                },
        }
    ]
}

附加该过程后，无法使用此日志设置断点：

C setBreakpoints: {"source":{"name":"api.c","path":"D:\\c_code\\quickfuncs\\api.c"},"lines":[246],"breakpoints":[{"line":246}],"sourceModified":false}
 R: {"success":true,"message":null,"request_seq":11,"command":"setBreakpoints","body":{"breakpoints":[{"id":3,"verified":true,"line":246,"message":null}]},"running":false,"refs":null,"seq":0,"type":"response"}
E breakpoint: {"reason":"changed","breakpoint":{"id":3,"verified":false,"line":246,"message":"Attempting to bind the breakpoint...."},"type":"breakpoint"}

请问你能帮帮我吗？

解决方案

我在https://github.com/Microsoft/vscode-cpptools/issues/2452上找到了解决方案。

pieandcakes 写道:

使用 MinGW，您必须向被调试者发送 Ctrl+C 以暂停。暂停按钮不起作用，因为我们无法通过MI 协议发送SIGINT 。gdb我们通常使用的命令是-exec-interrupt，但这不起作用。程序（不幸的是）是：

  1. pause在 UI 中点击
  2. 转到调试器并按Ctrl+c。

此时，被调试者应该停止。只有这样断点才能绑定。

这个解决方案对我有用。非常感谢。
