Unraveling the Mystery: How does auditwheel determine the minimum manylinux version?

Auditwheel, a powerful tool for packaging Python wheels, has taken the world of software development by storm. But have you ever wondered how it determines the minimum manylinux version required for your project? In this comprehensive guide, we’ll delve into the intricacies of auditwheel and explores its decision-making process.

The Importance of manylinux

Before we dive into the world of auditwheel, let’s take a step back and understand the significance of manylinux. Manylinux is a project that aims to provide a set of compatible Linux distributions for building and deploying Python packages. By specifying a manylinux version, you ensure that your package can be installed and run on a wide range of Linux systems, without worrying about compatibility issues.

Why do we need manylinux?

• Portability: Manylinux ensures that your package can be easily installed and run on different Linux distributions, without requiring tedious tweaking and testing.

• Consistency: By specifying a manylinux version, you can guarantee that your package behaves consistently across various Linux environments.

• Reliability: With manylinux, you can rest assured that your package will work as expected, without running into unexpected dependencies or incompatibility issues.

Auditwheel: The Guardian of manylinux

Auditwheel is a Python package that helps you identify the minimum manylinux version required for your project. It analyzes your package’s dependencies, system libraries, and Python version to determine the lowest common denominator that will ensure compatibility across various Linux distributions.

How does auditwheel work?

1. Auditwheel scans your package’s dependencies and system libraries, using tools like pip-compile and ldd.

2. It analyzes the dependencies and libraries to identify the minimum manylinux version required for each component.

3. Auditwheel compares the minimum manylinux versions required for each component and determines the highest common denominator.

4. The highest common denominator becomes the minimum manylinux version required for your project.

Determining the Minimum manylinux Version

Now that we’ve covered the basics of auditwheel, let’s dive into the process of determining the minimum manylinux version required for your project.

Step 1: Install auditwheel

pip install auditwheel

Step 2: Run auditwheel

auditwheel -v your_wheel_file.whl

Replace your_wheel_file.whl with the name of your wheel file.

Step 3: Analyze the Output

Auditwheel will generate a detailed report, including the minimum manylinux version required for your project. Look for the manylinux-x_y tag in the output, where x_y represents the minimum manylinux version.

auditwheel 4.5.0
Processing your_wheel_file.whl
...
manylinux_2_24
...

In this example, the minimum manylinux version required is manylinux_2_24.

Factors Affecting the Minimum manylinux Version

Auditwheel takes into account several factors when determining the minimum manylinux version required for your project. These include:

Factor	Description
Dependency versions	The versions of your package’s dependencies can affect the minimum manylinux version required.
System libraries	The presence of specific system libraries can impact the minimum manylinux version required.
Python version	The Python version used to build your package can influence the minimum manylinux version required.
Linux distribution	The Linux distribution used to build your package can affect the minimum manylinux version required.

Conclusion

In conclusion, auditwheel is a powerful tool that helps you determine the minimum manylinux version required for your project. By following the steps outlined in this guide, you can ensure that your package is compatible with a wide range of Linux distributions, without worrying about compatibility issues.

Remember, the minimum manylinux version required is a critical factor in ensuring the portability and reliability of your package. By understanding how auditwheel determines this version, you can take control of your project’s compatibility and deployment.

So, the next time you’re packaging your Python project, don’t forget to auditwheel it and ensure the minimum manylinux version is up to par!
