Invoke gdb from python script

Question

where should my python files be stored so that I can run that using gdb. I have custom gdb located at /usr/local/myproject/bin. I start my gdb session by calling ./arm-none-eabi-gdb from the above location.

I don't know how this gdb and python are integrated into each other.

Can anyone help.?

They aren't integrated into each other. You can do import os; os.system("./arm-none-eabi-gdb") — ForceBru

@ForceBru They aren't integrated into each other. Wrong answer. They are integrated quite well They are integrated into each other. sourceware.org/gdb/onlinedocs/gdb/Python.html#Python — Severin Pappadeux

You'd better use Python subprocess module - you could start GDB from python and drive GDB from python, passing commands on-the-fly

@user2118095 you might want to take a look at sourceware.org/gdb/onlinedocs/gdb/Python.html#Python

I was able to figure out. What I understood is

GDB embeds the Python interpreter so it can use Python as an extension language.

You can't just import gdb from /usr/bin/python like it's an ordinary Python library because GDB isn't structured as a library.

What you can do is source MY-SCRIPT.py from within gdb (equivalent to running gdb -x MY-SCRIPT.py).
