Try to get python3.10.12

Python Help
1

Ubuntu 22.04
There is /usr/bin/openssl file

I want to test locally not in container python 3.10.12
I didn’t find the way to install it. I tried through deadsnakes but it’s not shown in their repository

$apt search 3.10.12
$apt search python3.10 | grep 12

Though there is something on their page but I don’t understand how to use it. To install all deb packages? amd64 build of python3.10 3.10.12-1+focal1 : New Python Versions : “deadsnakes” team

Now I’m trying to compile python from sources. There is a problem with openssl
when I run

$ ./configure -C --with-openssl=/usr/bin/openssl --enable-optimizations --prefix=/usr/bin/python3.10.12
and then
$make

I receive logs with Could not build the ssl module!

The following modules found by detect_modules() in setup.py, have been
built by the Makefile instead, as configured by the Setup files:

As I understood there is openssl - executable file and also libssl-dev - shared library for development/building.
with ldconfig -p | grep ssl I found libssl3.so and tried to put its path to --with-openssl key
$ ./configure -C --with-openssl=/lib/x86_x64-linux-gnu --enable-optimizations --prefix=/usr/bin/python3.10.12
Also tried full path like /lib/x86_x64-linux-gnu/libssl3.so

This is supposed to be where the dev headers and libraries are not the openssl program.
You must install the openssl-dev package (i think that is that name) to get the files that python’s build needs.

Why can’t you use the python3 that is shipped in 22.04?

3

Because I want to test it locally before deploying images with python3.10.12 to production. And I’ll need it during development to have the same to prod environment

4

Got it, I do the same.
I my case its a production system on oracle linux 8.
We do not build python to test on a specific version we run the production environment in a VM so that we have exactly the right set of python versions and libraries.

Will you put into production you build of python? Is this the first time you have done this?

Evgentually I’ve managed to compile Python.
Just used ./configure without any parameters.
make
make test
make altinstall

But you first need to install Linux packages like libssl-dev, sqlite-dev (don’t remember exact name) and maybe other.
Now I use pyenv to do the same but easier
pyenv install -v 3.10.12
-v is needed to see if all is ok. Pyenv also requires that you preinstalled all needed OS packages before running pyenv install. It can compile without some libraries like ssl or sqlite. It will work until you’ll need to import this packages in python.
