在 VS 代码中无法使用 gcc 看到 std::vector 的元素

Maf*_*fia 10 c++ gcc mingw visual-studio-code

我目前正在使用 VS Code 来学习 C++,因为它易于设置并且比 VS Studio 轻得多。但是,我无法做的一件事是在调试模式下查看数组(或字符串等)的元素。

向量

我在这里搜索了解决方案,似乎启用漂亮的打印可以解决问题,但不幸的是它没有(我安装了 Python 3.6)。我也尝试过使用 VS Studio 编译器和调试器,但无法让它按照我想要的方式工作(基本上点击 F5 来编译单个 cpp 文件,而无需更改任何选项,只需单击一下)。

你们能帮我解决这个问题吗?我目前在 Windows 10 上使用 MinGW 编译器,具有以下任务文件:

"version": "2.0.0",
"tasks": [
    {
        "label": "echo",
        "type": "shell",
        "command": "g++",
        "args": [
            "-g", "${relativeFile}", "-o", "example"
        ],
        "group": {
            "kind": "build",
            "isDefault": true
        }
    }
]

对我来说这可行,但首先检查您是否有'c:\msys64\mingw64\share\gcc-8.3.0\python''c:\usr\share\gcc-8.3.0\python'文件夹并调整片段

launch.json
...
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "python import sys;sys.path.insert(0, 'c:\\msys64\\mingw64\\share\\gcc-8.3.0\\python');from libstdcxx.v6.printers import register_libstdcxx_printers;register_libstdcxx_printers(None)",
                    "ignoreFailures": false
                },
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],

我使用的方法就像上面描述的Georgy 一样。

*((int(*)[10])array._M_impl._M_start)

Debug console output:
-exec p array
$7 = {<std::_Vector_base<int, std::allocator<int> >> = {_M_impl = {<std::allocator<int>> = {<__gnu_cxx::new_allocator<int>> = {<No data fields>}, <No data fields>}, _M_start = 0x2924cb0, _M_finish = 0x2924cd8, _M_end_of_storage = 0x2924cf0}}, <No data fields>}

-exec p *((int(*)[10])array._M_impl._M_start)
$8 = {41, 18467, 6334, 26500, 19169, 15724, 11478, 29358, 26962, 24464}
