Basemap install fails after python upgrade

Running Python 3.12.0 on linux container.

After a upgrade of the container, basemap fails to install with the following errors:

The strange thing is that numpy is already installed and at version 1.26.0. Any suggestions on what the issue is would be appreciated.

Hi @goku-son! Python 3.12 is still not supported, normally I go a couple of weeks behind the official Python release until I get some time to update everything. Especially, basemap was still using distutils in some places, but distutils is not available anymore in Python 3.12, so even if you manage to build from source, it will fail at runtime.

Sorry! When I get some free time, I will prepare everything for Python 3.12.

That is more than fair. Thanks for the response and the insight @molinav!

The support for Python 3.12 is now part of the develop branch, and it will be available with the basemap release 1.4.0, which should take place in one or two days at maximum.

The basemap 1.4.0 wheels for Python 3.12 on Windows and GNU/Linux are already available in PyPI. Wheels for MacOS and the conda-forge packages will come in the following hours.
