如何配置 VS Code 以便能够进入调试 Python 脚本时加载的共享库 (.so)? [英] How to configure VS Code to be able to step into a shared library (.so) that is loaded when debugging a Python script?

问题描述

从命令行使用 gdb 我可以在加载共享库时中断.知道我拥有共享库的源代码，如何在 VS Code 中获得相同的行为?

Using gdb from the command line I'm able to break when the shared library is loaded. How can I get the same behavior in VS Code knowing that I have the source code of the shared library?

推荐答案

对我来说它以某种方式工作.

For me it works somehow.

这是我的设置:

• Ubuntu 18.04，调试我从 Python3 加载的 C++ 共享库(更具体地说 - 通过 Cython，但 IIRC 在通过 ctypes 加载 .so 时同样有效，我还记得它在调试纯 C 库时工作类似设置)
• 在 VSCode 中，我有一个项目可以编译成 .so
• 在那里我放了一堆断点
• 我创建了一个启动配置(下面的文字)
• 另外，我已经用调试信息编译了 .so

这是我的launch.json(在大多数情况下，它是样板文件，我只填写了程序"和参数"部分并​​设置了PYTHONPATH环境变量).

here's my launch.json (for the most part, it's boilerplate, I only filled in the "program" and "args" parts and set up PYTHONPATH environment var).

注意:stopAtEntry:false"(默认情况下)似乎很重要，否则 VSCode 会尝试定位条目 .c 文件或其他内容.

note: it seems to be important to have "stopAtEntry:false" (which it is by default), otherwise VSCode tries to locate an entry .c file or something.

                "ignoreFailures": true
            }
        ]
    }
]

无论如何，在这个设置中，我看到我的 VSCode 显示在我的断点处停止执行

anyway, in this setup I see my VSCode showing the execution stopping on my breakpoints
