The situation is definitely unusual, but I will try to explain.
I have a simulator that uses a C++ kernel and a bunch of simulation
components. Now I want to wrap both kernel and components and add scripting
and inspection functionality in Python. Python will be used to instantiate
the simulation components and run what I will call the "architecture".
So far, so good, I have everything wrapped.
The problem is that I might want to debug the architecture. I was thinking of
using GDB, but since components are instantiated in Python (note that I might
have more objects that belong to one class), it is hard to get a reference to
them. Setting a breakpoint on the source code is be easy, but putting a watch
on a variable is much more tricky.
In the end what I would like to have is a sort of python-controlled GDB
breakpoint mechanism, where I set a condition in python and C++ is stopped
when the condition arises.
Getting a reference to the object/variable should be enough to put a watch in
GDB (and here's why I'm trying to pass from PyObject to the C++ address).
Any suggestion is welcome!
