Python Forum

The following serves as the foundation of my code; however, I encounter an error: "ImportError: No module named gdb". How can I resolve this issue? Google Bard AI has suggested using the command pip install gdb in the terminal, but I would like the GDB Python API to be installed permanently within my project. I want it to reside in the project's third-party or binary folder, similar to how the python312.dll can be placed in the binary folder. This way, it remains unaffected even if I reinstall the operating system. I'm building a game engine, and I want to make it easy for users to get started without requiring them to install the GDB Python API. I want to replicate the experience of using VSCode, where users can install GCC without needing to install GDB Python API.

Python version: 3.12.0

@Larz60+, I know how to use GDB with command line but I don't know how to use with Python. I forgot to generalize my question to make it easier to answer.

The question should be:

"How to fix ImportError: No module named X (Python in C++)". So, it's not only about GDB but a general question on how to fix that error with Python in C++.

mingw64\share\gdb
├── python/
│   └── gdb/
│       └── ...
├── syscalls/
├── system-gdbinit/
└── gdbinit

It's quite challenging. I finally know how to import but can anyone tell me what is the location of the right GDB Python API? Maybe I'm using the wrong path.

Note: Absence of errors does not mean success. For instance, calling PyImport_AddModule("abcde") may result to import abcde not having error, but the module remains empty.

sysPath = PySys_GetObject("path");

PyObject *gdbModule = PyImport_ImportModule("gdb");
    // (no error)

Python with PyRun_SimpleString():

import gdb
print(gdb.PYTHONDIR) # AttributeError: module 'gdb' has no attribute 'PYTHONDIR'
print(gdb.current_language()) # AttributeError: module 'gdb' has no attribute 'current_language'
print("Hello, World!")
