I downloaded VS community 2022 and I know how to access the developer command prompt. I'm using the one called x64 Native Tools Command Prompt for VS 2022

I ran a command to compile my python code that was converted to c with the following command:

H:\Users\LindaJim\Documents\SourceCode\Software\aws_pc_backup\src\c>cl /O2 /I"C:\\Users\\jschw\\AppData\\Local\\Programs\\Python\\Python3112\\include\\" aws_pc_backup.c C:\\Users\\jschw\\AppData\\Local\\Programs\\Python\\Python3112\\libs\\python311.lib
Microsoft (R) C/C++ Optimizing Compiler Version 19.35.32216.1 for x64

aws_pc_backup.c
Microsoft (R) Incremental Linker Version 14.35.32216.1

/out:aws_pc_backup.exe
aws_pc_backup.obj
C:\\Users\\jschw\\AppData\\Local\\Programs\\Python\\Python3112\\libs\\python311.lib
Creating library aws_pc_backup.lib and object aws_pc_backup.exp

When I ran the program, I got this, though. Obviously, it doesn't know about the requests package. Do I have to link something in with the executable?

H:\Users\LindaJim\Documents\SourceCode\Software\aws_pc_backup\src\c>aws_pc_backup.exe -m:lb
Traceback (most recent call last):
File "src\\python\\aws_pc_backup_main.py", line 7, in init python.aws_pc_backup_main
ModuleNotFoundError: No module named 'requests'

It is part of visual studio C++.
Once you have that installed there are bat files that setup environment in the terminal.
Then you can use cl, nmake etc
