Package GDAL for Python 3.9 on Linux

I have a Python module that I need to package as a wheel and publish to a private PyPi. It has a dependency on GDAL>=3.2.2.

Everything needs to run on Linux, Python 3.9.

So I need to find a way to make a wheel from GDAL and store it in my private PyPi.

I tried every possible guide I found but can't make a wheel for Python 3.9 on Linux. The farthest I got was a wheel for 3.8, but when installing it on another machine (or docker) it still needs some other dependencies.

These are my working steps for GDAL 3.2.2 on Python 3.8:

  1. downloaded the tar.gz from PyPi GDAL 3.2.2
  2. Extracted it and ran:
    sed -i '/gdal_config/c\gdal_config = /usr/bin/gdal-config' setup.cfg
  1. Then ran:
    sudo add-apt-repository ppa:ubuntugis/ppa
    sudo apt-get update -y
    sudo apt-get install gdal-bin -y
    sudo apt-get install libgdal-dev -y
    export CPLUS_INCLUDE_PATH=/usr/include/gdal
    export C_INCLUDE_PATH=/usr/include/gdal
  1. finally ran:
    python setup.py bdist_wheel

This created a wheel for Python 3.8 on Linux, but still missing some dependencies... The same process fails for Python 3.9 (appears to be due to some deprecated method) There are precompiled versions for Windows that do work, but I need a solution for Linux.

And lastly, it needs to work in a disconnected network - no Internet. But I can prepare the wheel in a connected environment

Tried everything I could think of...

EDIT

ok, it seems the compilation failed for Python 3.9 because I was missing python3.9-dev. So I also needed:

sudo apt-get install python3.9-dev

So now I can create a wheel for 3.9 which I can install on fresh machines, but when trying to import the module I get:

>>> import osgeo
