Visual Studio Code，调试子进程不起作用

我有这个确切的问题：https://github.com/Microsoft/vscode-cpptools/issues/511 https://github.com/Microsoft/vscode-cpptools/issues/511

但那里的解决方案不起作用。

我尝试过相同的简单示例代码，

#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>

int main()
{
    pid_t pid = fork();
    if (pid != 0) {
        printf("Main process\n");
    } else {
        printf("Forked process\n");
    }

    return 0;
}

我使用 -g 进行编译，我的 launch.json 文件如下所示。

我单击“调试”，将断点设置到第一行。在第一站，我进入-exec set follow-fork-mode child在调试控制台下，它给了我返回=cmd-param-changed,param="follow-fork-mode",value="child"。那么它就行不通了。它转到父进程（pid 显示不为 0）。我尝试使用以下命令将其设置在 launch.json 文件本身中{"text": "-gdb-set follow-fork-mode child"}，但这也行不通。

        "configurations": [

        { 
            "name": "(gdb) Attach",
            "type": "cppdbg",
            "request": "attach",
            "program": "${workspaceRoot}/a.exe",

            "miDebuggerPath": "C:\\cygwin64\\bin\\gdb.exe"
        },
            {
                "name": "(gdb) Launch",

                "environment": [],
                "externalConsole": true,

                "miDebuggerPath": "C:\\cygwin64\\bin\\gdb.exe",
                "setupCommands": [
                    {
                        "description": "Enable pretty-printing for gdb",
                        "text": "-enable-pretty-printing",
                        "ignoreFailures": true
                    }
                ]
            }
        ]
    }

我遇到了同样的问题，我解决了这个问题：

 "setupCommands": [
                    {
                        "description": "Enable funcy printing to gdb",
                        "text": "-enable-pretty-printing",
                        "ignoreFailures": true
                    },
                    {   "description":"In this mode GDB will be attached to both processes after a call to fork() or vfork().",
                        "text": "-gdb-set detach-on-fork off",
                        "ignoreFailures": true
                    },
                    {   "description": "The new process is debugged after a fork. The parent process runs unimpeded.",
                        "text": "-gdb-set follow-fork-mode child",
                        "ignoreFailures": true
                    }
                ],
