Hi, I'm observing a segmentation fault as described in jupyter/qtconsole#585 of which I believe basemap is the root cause.

This is due to underlying conda c-library conflicts.

It seems the underlying issue with basemap support is the build process for libgeos. I wonder if life would be easier by making calls to https://pygeos.readthedocs.io/en/stable/ instead?

To replicate this issue, this is the minimal build script that results in failure.

This occurs on windows system linux - ubuntu 22.04 & 20.04

conda env remove nept -y
conda create -n nept -c conda-forge  python=3.9.12 -y
conda activate nept
conda install -c conda-forge basemap qtconsole -y
jupyter qtconsole #This fails with segmentation fault.

Hi @SoundsSerious! I am not an expert on Miniforge/Anaconda, but I tried to follow your steps in a clean Miniforge installation on Windows 64-bit and your commands seem to work successfully.

First I create the new environment:

(base) C:\Users\vic>conda create -y -n nept -c conda-forge python=3.9.12

Please update conda by running

    $ conda update -n base -c conda-forge conda

Or to minimize the number of packages updated during conda update use

     conda install conda=23.11.0

Second, I activate the "nept" environment and install basemap and qtconsole from the conda-forge channel:

(base) C:\Users\vic>conda activate nept

(nept) C:\Users\vic>conda install -y -c conda-forge basemap qtconsole

I may try later with Miniforge on Linux 64-bit too. In the meantime, may I ask you to provide a full traceback of all your steps? Maybe we can see there the discrepancy between your environment and mine. This kind of segfaults I got them in the past when mixing conda-forge and anaconda channels (I think it is because numpy is packaged differently).
