如何在 Visual Studio Code 中为 C++ 启用漂亮打印？

Question

我正在尝试使用 MinGW GDB python 调试器在 Visual Studio Code 中为 C++ 启用漂亮的打印。

我按照 “这适用于使用 Eclipse CDT 的 MinGW 用户” 标题下的 here 描述的步骤进行操作，但是当我尝试使用 "externalConsole": true 启动调试器时，我得到以下日志输出调试控制台：

1: (189) LaunchOptions{"name":"g++.exe - Build and debug active file","type":"cppdbg","request":"launch","program":"c:\\Users\\Ben Wilson\\Documents\\Scripts\\CodingChallenges\\movie.exe","args":[],"stopAtEntry":false,"cwd":"C:\\Users\\Ben Wilson\\Documents\\Scripts\\CodingChallenges","environment":[],"externalConsole":true,"MIMode":"gdb","miDebuggerPath":"C:\\MinGW\\bin\\gdb-python27.exe","setupCommands":[{"description":"Enable pretty-printing for gdb","text":"-enable-pretty-printing","ignoreFailures":true}],"preLaunchTask":"C/C++: g++.exe build active file","logging":{"engineLogging":true},"__configurationTarget":5,"__sessionId":"c62bc9d3-8c55-4dfb-b413-c91d22f3232e"}

我尝试设置"externalConsole": false，并将此输出发送到调试控制台：

            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
}

另外，单独运行 gdb-python27 可执行文件似乎没有任何作用（不确定这是否是预期行为）

C:\Users\Ben Wilson\Documents\Scripts\CodingChallenges>C:\MinGW\bin\gdb-python27.exe

C:\Users\Ben Wilson\Documents\Scripts\CodingChallenges>

有没有人经历过这种情况或知道在这里做什么？

Answer 1

解决方案

修复问题：

1. 从此link卸载mingw并安装mingw64
2. 修改launch.json 和command 中的miDebuggerPath 和tasks.json 中的cwd 以匹配新文件位置
3. 将新的 mingw64 bin 位置添加到 PATH
4. 修改c_cpp_properties.json 中的includePath 和compilerPath 以匹配新文件位置

Answer 2

我也遇到过同样的问题。我的环境：

• 本地/远程：Ubuntu 18.04 桌面/服务器
• VSCode 1.60 + vscode_remote
• g++ 与 gdb 8

-enable-pretty-printing 的设置根本不起作用：

以下解决方案适用于我：

1. 检查您的 gdb 是否支持 gdb 的 python 模块提供的“漂亮打印”： readelf -d $(which gdb) | grep python。 如果没有列出任何内容，很遗憾，您必须从源头重新构建您的 gdb。
2. 在重建 gdb 之前必须安装一些要求： sudo apt install python libpython-dev # will install python 2.7 and PythonLib in Ubuntu 18.04
3. 从here下载最新的gdb并解压。
4. 使用以下配置执行构建和安装：

   ./configure --with-python
   make all -j16
   sudo make install -j16
   

5. 完成！

附言。 conda config --set auto_activate_base false 并重新打开你的 shell 以确保 gdb 加载了正确版本的 python。
