Introdution
This is a simple example of a mixed debugging in c++ and Python (inspired by https://www.youtube.com/watch?v=9q-LHP7cMfg&ab_channel=MichaelVanslembrouck). In the example is Python3.10 used and installed under c:\python310-64 if you have installed it somewhere else you need to edit it in the spam.vcxproj and when you create the venv for the Python project.
The issue
It is possible to build and set breakpoints when you start the debugging with the c++ project as startup project (as described in the YouTube tutorial). The issue occurs when you try to do it with the PythonApplication as startup project. The Enable native code debugging flag is checked in the Python project. Under Debug\Attach to process...\Attach to: is set to Python (native) code.
(I have tried to use both Python39-64 and Python310-64)
Repo structure
The spam.sln is the solution file for exampel
The spam folder contains the c++ project (spam.vcxproj) which builds the spam c++ module and output this into the PythonApplication folder.
The PythonApplication folder contains PythonApplication.pyproj and PythonApplication.py you need to build a venv in this folder aswell (open a comandpromt in PythonApplication folder and type: c:\python310-64\python.exe -m venv venv).
