Building Python from source with zlib support can be a useful task for developers who want to ensure that their Python installation includes support for the zlib compression library. In this article, we will explore three different ways to solve this problem.
Option 1: Using the configure script
The first option involves using the configure script that comes with the Python source code. This script allows you to customize various aspects of the build process, including enabling zlib support.
This command will configure the build process to include zlib support. Once the configuration is complete, you can proceed with the usual make and make install commands to build and install Python.
Option 2: Modifying the Makefile
If you prefer a more manual approach, you can modify the Makefile directly to enable zlib support. Open the Makefile in a text editor and locate the line that starts with “LIBS=”. Add “-lz” at the end of this line to link against the zlib library.
LIBS= -lpthread -ldl -lutil -lm -lz
Save the Makefile and then proceed with the make and make install commands to build and install Python.
Option 3: Using a package manager
If you are using a package manager to install Python, such as apt or yum, you can specify the zlib package as a dependency. This will ensure that zlib support is included in the Python installation.
sudo apt-get install zlib1g-dev
This command installs the zlib development package, which includes the necessary files for building Python with zlib support. Once the package is installed, you can use the package manager to install Python as usual.
After exploring these three options, it is clear that using the configure script (Option 1) is the most straightforward and recommended approach. It allows for easy customization of the build process and ensures that zlib support is included in the Python installation. However, the other options can be useful in certain scenarios where modifying the Makefile or using a package manager is preferred.
