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

Question

我按照这里的说明进行操作。安装了cpptools，并创建了tasks.json文件，其内容如下：

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

并且使用以下内容打开launch.json文件：

{
    "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"
            }
        }
    ]
}

当我按下 Ctrl+Shift+B 时，代码会生成 a.exe。当我运行调试时，它会输出以下内容：

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

但是这段代码没有命中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逐步执行代码？

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 build）4.9.2
• g++.exe（x86_64-win32-seh-rev201506，mingwpy build）4.9.2

更新

• 在评论中的讨论中，我被要求使用m32标志运行gcc，因为我的编译器是64位的，它可能会生成64位二进制文件。 但是gcc -m32 helloworld.c会产生错误，类似于这个。这里的评论解释了这一点，需要在编译时添加i686-w64-mingw32 / x86_64-w64-mingw32标志。 但是gcc -x86_64-w64-mingw32 helloworld.c会产生“未识别的语言”错误，gcc -i686-w64-mingw32 helloworld.c会产生“未识别的命令行选项”错误。 我做错了什么？
• 此外，这篇文章说，目前只能在Linux上进行调试，而在Windows上不行，是真的吗？

你需要设置调试符号的路径。symbolSearchPath=C:\\path_1;D:\\path_2;etc... - Ingenioushax

为配置 launch.json，这是一篇很好的 GitHub VSCode 小文章。希望能对您有所帮助。https://github.com/Microsoft/vscode-cpptools/blob/master/launch.md - Ingenioushax

@Ingenioushax，但是那些调试符号在哪里呢？就像我所说的，在我的情况下，gcc -g helloworld.c没有生成任何调试符号。 - Mahesha999

注意Mahesh，你已经在“Program Files”中安装了Mingw <-- 这是一个带有空格的文件夹。这可能会导致一些神秘的问题；应该安装到C:\mingw。 - rdtsc

Answer 1

如果您想让command.PickProcess起作用...

应该使用“：”而不是“.” - 因此:

{
    "name": ".NET Core Attach",
    "type": "coreclr",
    "request": "attach",
    "processId": "${command:pickProcess}"
}

应该能解决你的问题 :)

我相信您正在尝试使用VS Code调试器（cppvsdbg）而不是gdb（cppdbg）。对于我来说，这个修改过的launch.json与TDM-GCC和gdb作为调试器一起使用。

{
"version": "0.2.0",
"configurations": [
    {
        "name": "C++ Launch",
        "type": "cppdbg",
        "request": "launch",
        "args": [],
        "stopAtEntry": false,
        "cwd": "${workspaceRoot}",
        "environment": [],
        "externalConsole": true,

        "linux": {
            "program": "${workspaceRoot}/a.out",
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        },
        "osx": {
            "MIMode": "lldb"
        },
        "windows": {
            "miDebuggerPath": "C:\\TDM-GCC-64\\bin\\gdb.exe",
            "program": "${workspaceRoot}\\a.exe",
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    },
    {
        "name": "C++ Attach",
        "miDebuggerPath": "C:\\TDM-GCC-64\\bin\\gdb.exe",
        "type": "cppdbg",
        "request": "attach",
        "program": "${workspaceRoot}/a.exe",
        "processId": "${command:pickProcess}",
        "linux": {
            "MIMode": "gdb",
            "program": "${workspaceRoot}/a.out",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        },
        "osx": {
            "MIMode": "lldb"
        },
        "windows": {
            "MIMode": "gdb",
            "miDebuggerPath": "C:\\TDM-GCC-64\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    }
    ]
}

Answer 3

我以前也遇到过这个问题。在我的情况下，编译器默认生成了一个发布应用程序。它没有调试符号。

因此，请确保您生成了一个用于调试的调试应用程序。

祝你好运！
