使用 gcc、g++ 和 gdb 在 Window 7 上设置 VSCode 进行 C/C++ 调试

我正在遵循以下指示here。安装了cpptools。已创建tasks.json包含以下内容：

{
    "version": "0.1.0",
    "command": "g++",
    "isShellCommand": true,
    "showOutput": "always",
    "args": ["-g", "helloworld.c"]
}

And launch.json包含以下内容：

{
    "version": "0.2.0",
    "configurations": [

        {
            "name": "C++ Launch (Windows)",
            "type": "cppvsdbg",
            "request": "launch",
            "program": "${workspaceRoot}/a.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceRoot}",
            "environment": [],
            "externalConsole": false,
            "windows": {
                "MIMode" : "gdb",
                "miDebuggerPath": "C:\\Mahesh\\Program Files\\mingw\\MinGW\\bin\\gdb.exe"
            }

        },
        {
            "name": "C++ Attach (Windows)",
            "program": "${workspaceRoot}/a.exe",
            "type": "cppvsdbg",
            "request": "attach",
            "processId": "${command.pickProcess}",
            "windows": {
                "MIMode" : "gdb",
                "miDebuggerPath": "C:\\Mahesh\\Program Files\\mingw\\MinGW\\bin\\gdb.exe"
            }
        }
    ]
}

当我做Ctrl+Shift+B，代码构建，生成a.exe。当我运行调试时，它给出以下输出：

The thread 9524 has exited with code 0 (0x0).
Hello World!!!
The program '[7876] a.exe' has exited with code 0 (0x0).

但代码没有达到我在代码中设置的调试点。你可以看到，它正在打印“Hello World!!!”。我该如何配置才能在调试时单步执行代码？

环境：

• 程序“[7876] a.exe”已退出，代码为 0 (0x0)， 配置为“i686-pc-mingw32”。
• gcc.exe（x86_64-win32-seh-rev201506，mingwpy 版本）4.9.2
• g++.exe（x86_64-win32-seh-rev201506，mingwpy 版本）4.9.2

Update

• 在讨论中comments，我被要求运行 gccm32标志，因为我的编译器是 64 位的，它可能会生成 64 位二进制文​​件。但gcc -m32 helloworld.c给出了类似的错误this. The 在这里发表评论解释它与-m32选项。它要求添加i686-w64-mingw32/x86_64-w64-mingw32编译时的标志。但gcc -x86_64-w64-mingw32 helloworld.c gives language not recognized error, gcc -i686-w64-mingw32 helloworld.c gives unrecognized command line option。我做错了什么？
• Also this文章说目前只能在 Linux 上进行调试，而在 Windows 上则不行。是这样吗？

我相信您正在尝试使用 VS Code 调试器 (cppvsdbg) 而不是 gdb (cppdbg)。此修改launch.json我使用 TDM-GCC 和 gdb 作为调试器：
