Something broke installation on windows?

This is with conda 25.1.1 and conda-build 25.1.2 on python 3.12. I have no proof, but my suspicion is that this might be related to the encoding errors that started appearing across the board recently (it seems that a default somewhere or under certain circumstances was switched away from utf8).

The post-link script:

:: Make sure that gdk-pixbuf's loaders.cache is fully up-to-date.

:: Packages that install gdk-pixbuf loaders (such as librsvg) should have
:: post-link and post-unlink scripts that just execute this one, which will be
:: available as `%PREFIX%\Scripts\.gdk-pixbuf-post-link.bat`.

"%PREFIX%\Library\bin\gdk-pixbuf-query-loaders.exe" --update-cache >> "%PREFIX%/.messages.txt" 2>&1
if errorlevel 1 exit 1

The internet says that error code is due to missing DLLs so maybe something in the stack changed enough to make this crash. I guess we could take a look in the gdk-pixbuf feedstock and try to run the same command as part of the tests.

That would be a failure of our ABI pins somewhere 🥲

This is the feedstock. 🙃

@conda-forge-admin, please rerender

[conda-forge-webservices]

Hi! This is the friendly automated conda-forge-webservice.

I just wanted to let you know that I started rerendering the recipe in #49.

[friendlyvillain]

Exactly same issue related to gdk-pixbuf occurs in Windows OS. (Python: 3.12, Build: conda 25.1.1)

[traversaro]

I guess the root issue is conda-forge/libiconv-feedstock#48 . As quick workaround is to pin libiconv to 1.17 .

Thank you! This is the only way to treat the problem in the current step.

This is conda-forge/libiconv-feedstock#49.

conda-forge/libiconv-feedstock#49 was merged now.
