How I can use CMake for linking Python 2 and Python 3 libraries for a same software
Download this code from https://codegive.com
Using CMake to link Python 2 and Python 3 libraries for the same software involves some considerations, as Python 2 and Python 3 have distinct APIs. Below is a step-by-step tutorial on how to achieve this, along with code examples.
Make sure you have CMake installed on your system. You can download it from the official CMake website or use a package manager like apt, brew, or chocolatey.
Assume you have a project with the following structure:
Create the main CMakeLists.txt in the project root:
Create the CMakeLists.txt file in the src/ directory:
Create the CMakeLists.txt file in the python/ directory:
Assuming you are using pybind11 for Python bindings, create python/mymodule_py.cpp:
Now, you can build your project using the following commands:
Assuming your Python script is in the project root:
Run the script:
This tutorial provides a basic setup for linking Python 2 and Python 3 libraries using CMake. Adjustments may be needed based on your specific project requirements. Additionally, ensure that you have the necessary dependencies installed, such as pybind11 and the appropriate Python development packages.
