Building Python 3.11

This article focuses on building CPython for common Linux server operating systems.

These scripts will be tested in fresh Docker container.

I'll install dependencies from package manager if possible, or I'll try compile myself if that makes sense.

The dependencies doesn't change much between these CPython versions, so Python 3.12 and 3.10 may have the exact same process. (Obviously the link and the filename in the script must be changed.)

All examples, unless --prefix is set, uses altinstall target for installing Python onto the system, which will install CPython into /usr/local by default and will not affect default python or python3 command.

Operating Systems

Distro Note
Debian 10+, Ubuntu 18.04+ (For Ubuntu 18.04) Additional info required by pkgconfig.
CentOS 7 Additional info required by pkgconfig.
CentOS uses tk 8.5, while Python 3.10 and later uses tk 8.6 by default.
Rocky Linux 8
Rocky Linux 9
openSUSE Leap 15
openSUSE Leap 42 Building OpenSSL 1.1.1 or later version is required.
Alpine Linux 3.18

Debian 10+, Ubuntu 18.04+

CentOS 7

Tested on centos:7

The script should work with RHEL7 based systems.

Update on Jun 26, 2023: Thanks to the decision from Red Hat, I'm no longer sure if RHEL-derived system will work anymore since I have no intension to apply Red Hat developer subscription. Also, well done to someone that came up with that decision, making Canonical's Ubuntu Server more attractive for enterprise users than ever.

  • Note: _tkinter module is not available because Python 3.11 requires tk 8.6, while package tk-devel is using tk 8.5.

Build RPM

Checkout my repo about building Python 3.10 for EL7.

That being said, since that is focus on Python 3.10, it may require changes here and there, so use it carefully.

Alpine Linux 3.18

IMPORTANT: Alpine has python3 package that can be Python 3.11. BEWARE THAT IT MAY GET VERY CONFUSING IF MULTIPLE PYTHON 3.11 BUILDS ARE INSTALLED.

Tested with alpine:3.18.

The package release cycle for Alpine Linux is really fast, consider using apk add python3 to install officially supported Python.

apk add musl-dev ncurses-dev bzip2-dev gdbm-dev libnsl-dev xz-dev openssl3-dev tk-dev libuuid \
        readline-dev sqlite-dev libffi-dev gcc make automake wget tar gzip
wget https://www.python.org/ftp/python/3.11.0/Python-3.11.0.tgz
tar -xvf Python-3.11.0.tgz
cd Python-3.11.0
./configure --enable-loadable-sqlite-extensions
make -j$(nproc)
make altinstall

Testing (before make altinstall)

#!/bin/sh
apk add gdb g++ musl-locales musl-locales-lang
make test

  • Seems like CPython doesn't like i18n implementation in musl, all failures are related to locales and charmaps.
