As a short-term fix, I marked the windows packages of the latest build as broken (conda-forge/admin-requests#418), so a default install of the latest version on windows should work again.

Now we of course still need to figure out why this started to fail with the latest rerendering.

[jorisvandenbossche]

So I think that in the end this didn't have to do with the rebuild of fiona itself, but with a rebuild of gdal that happened at almost the same time.

You can see see here in one of the failure reports that also the gdal build number was bumped when this started failing: kedro-org/kedro#1377 (comment)

And I was able to now test it locally on a Windows machine, and if using the latest gdal build, the "broken" fiona build is also working fine. But then when installing the previous gdal build (gdal 3.4.2 build 2, https://anaconda.org/conda-forge/libgdal/files), it starts to fail.

And the reason this started working again is probably also not because of marking the fiona build as broken, but just that more or less at the same time, it got fixed in gdal: conda-forge/geotiff-feedstock#47 (bumping build number of libgdal to 3), conda-forge/gdal-feedstock#616, conda-forge/geotiff-feedstock#47

[akrherz]

There's now a new GDAL build 4 for version 3.4.2. I am unsure what to suggest be tried here...

[jorisvandenbossche]

You mean that the error re-appeared with the new gdal build?

[akrherz]

You mean that the error re-appeared with the new gdal build?

I have not tried the new build to see if it has the same troubles as other recent GDAL builds have had.

[jorisvandenbossche]

Since there have been no reports (and our own tests are passing on #195), I think we can assume it is still working.

Closing this issue, as there is nothing left to do / all should be resolved.
