Embedding Python In C/C++

Published: 10 Oct 2015 Category: programming_study

Preparatory Work

Copy all necessary Python files to your project directory. It would be convenient that your program could still work even if other people’s computer doesn’t install a Python toolkit.

What We need:

(1) “C:\Python27\include”. This directory will be added to VS-C++

(2) “C:\Python27\lib”. This directory will be added to

(3) Copy all files in “C:\Python27\DLLS” and “C:\Python27\Lib” to one directory, e.g: “Python27”. This is gonna be a huge directory..but you can remove many packages that you don’t actually need.

So finally my project structure just as below:

Coding Work

Now that we created a huge Python27 directory containing all packages, we can directly start our coding work by:

from time import time

However if you try to import those 3rd-party packages, such as numpy/cv2, your program will crash without any warning. Well, you probably already installed those packages into “C:\Python27\Lib\site-packages”(now what we got is a Python27 directory, so it is “Python27\site-packages” in your project directory). Before import any package, you should add one more line ahead:

import cv2

Now you can import cv2 and manipulate images successfully!

Hard Wording Remainded

It would be a frustrated if you’ve written a lot of codes but the program can not run - it just crash, without any warning. Debugging would be a nightmare.
