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

Question

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

我根据https://github.com/Microsoft/vscode-cpptools/blob/master/launch.md

配置了launch.json

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "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
                },
        }
    ]
}

附加进程后，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"}

你能帮帮我吗？

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

pieandcakes 写道：

With MinGW you have to send Ctrl+C to the debuggee to pause. The pause button doesn't work because we can't send SIGINT through gdb's MI protocol. The command we typically use is -exec-interrupt but that doesn't work. The procedure (unfortunately) is:

Hit pause in the UI

Go to the debuggee and press Ctrl+c.

At that point the debuggee should stop. It is only then that the breakpoints bind.

这个解决方案适合我。非常感谢。
