GDAL package can't be imported after installing using micropip about pyodide HOT 4 OPEN

Hi)
As a common user, I found that first link references to alpha version 0.22.0a3, and I have tried to find this package in support list in release versions (0.22.0 or greater), and didn't find it...

Then I tried to use Pyodide REPL on version 0.22.0a3, but it didn't work too
So, maybe this package had some problems with installing in Pyodide...
Anyway, you can find file meta.yml for this module. You can try to update and use this file. Reference for new packages in Pyodide

@deeplook @ryanking13 does this issue make sense to you? Is gdal supposed to provide a module named osgeo? I see that pyodide._api.lockfile_packages.gdal.imports is an empty list, so gdal doesn't define any imports?

The list in https://pyodide.org/en/0.22.0a3/usage/packages-in-pyodide.html is incorrect. The gdal package in that list means the shared library (libgdal) not the gdal python package. We removed the non-python packages from that list, but probably the alpha release doc has incorrect package list.

We are using libgdal in fiona (and geopandas that uses fiona) but we don't have gdal python binding itself in Pyodide yet. I think including it won't be very hard because we already have libgdal. But someone would need to work on it.

Thanks, that's really helpful.

I'm surprised that the standard build of GDAL didn't automatically build the Python library. There might be a way to turn this on in the build script for GDAL - I'll have a little look myself, but if anyone else knows how to go about this then please feel free to chip in.
