Dependency Analysis

Please note that this analysis is highly experimental. The aim here is to make maintenance easier by inspecting the package's dependencies. Importantly this analysis does not support optional dependencies, please double check those before making changes. If you do not want hinting of this kind ever please add bot: inspection: false to your conda-forge.yml. If you encounter issues with this feature please ping the bot team conda-forge/bot.

Analysis of the source code shows no discrepancy between the library's imports and the package's stated requirements in the meta.yaml.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Windows compile failure in poppler/ImageEmbeddingUtils.cc:

C:\Program Files (x86)\Windows Kits\10\include\10.0.17763.0\shared\basetsd.h(77): error C2371: 'INT32': redefinition; different basic types
d:\bld\poppler-split_1638388910887\_h_env\library\include\jmorecfg.h(216): note: see declaration of 'INT32'

[pkgw]

Another Windows compile failure:

D:\bld\poppler-split_1638406403698\work\glib\poppler-document.cc(34): fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory

Other files use a guard:

#ifdef HAVE_UNISTD_H
#    include <unistd.h>
#endif

update: Then:

glib\poppler-document.cc(3480): error C3861: 'close': identifier not found

update 2: OK, there are enough issues in the new glib FD APIs that we're not going to be able to get them to build on Windows in any reasonable way. Filed upstream: https://gitlab.freedesktop.org/poppler/poppler/-/issues/1180

Thanks for chasing this @pkgw!

[oschwartz10612]

@conda-forge-admin, please rerender

[Fdawgs]

Is it worth leapfrogging this version? v22.01.0 seems to have included all the fixes requested in https://gitlab.freedesktop.org/poppler/poppler/-/issues/1180

[pkgw]

@Fdawgs Yes, we should just skip this one. Hopefully the bot will file a PR for 22.01 soon, but someone can always do that manually too. I'll close this PR since there's a new version to work on now.
