Building Python 3 C Modules in macOS with Odd Compiler Options - A Step-by-Step Tutorial
In this tutorial, we will walk you through the process of building Python 3 C modules on macOS using unusual compiler options. While building C modules for Python, we'll use some unconventional compiler flags to demonstrate how you can customize the build process.
Prerequisites:
Step 1: Create a C Module
Let's start by creating a simple C module that we will build and import into Python. Create a file named examplemodule.c with the following content:
Step 2: Write a Setup Script
Create a setup.py script to specify how to build the C module. Place the following code in setup.py:
Step 3: Build the C Module
Now, let's build the C module using some odd compiler options. We will use gcc with a non-standard optimization flag for demonstration purposes. Open your terminal and navigate to the folder containing examplemodule.c and setup.py.
Run the following command to build the module:
In this command:
Step 4: Import and Use the Module
After building the C module, you can import and use it in Python. Open a Python shell or create a Python script with the following content:
Run the Python script. You should see the following output:
Congratulations! You have successfully built a Python 3 C module on macOS with non-standard compiler options.
Conclusion
In this tutorial, you learned how to create a Python C module, write a setup script, and build the module with custom compiler options in macOS. While we used an odd compiler option for demonstration purposes, you can customize the compiler flags to suit your specific needs when building C modules for Python.
