aheinecke triaged T4347: gpg4win 3.1.5 pinentry fails on some systems as High priority.

Strange, even if they are missing in the Gpg4win insttall dir they should be picked up from GnuPG which is added to PATH.

werner triaged T4367: gnupg fails to build with gcc9 as Normal priority.

Libdns is not our own code and our intention was to keep it in sync with upstream. However, after some initial success the upstream author lost interest. We now consider to rework the code to remove a bit of the more creative use of C99 and maybe even get rid of some of the used C99 features (gnupg is mainly C90 with some exceptions).

So, the keyserver operator had thrown in a hockeypuck server in the pool, causing this.. While the keyserver remains in the exclude list until confirmation it has been resolved, that explains the behavior and it has been made clear that separate software needs to use different names in the future.

This is not about a function, but about the variable _gpgrt_functions_w32_pollable. And this is not about exporting the variable from the library, but about declaring it as extern in gpgrt-int.h, so that gpgrt-int.h can be included in multiple translation units without defining the variable in each.

This function is not exported on purposes. Even the name of the header file indicates that tis is internal. External, that is public functions of the API, are defined gpgrt.h and only made externally visible by including them in the .def file.

Interesting. Thanks for reporting this. This happened in the past because images had a "content-id" (so they were marked to be an embedded image) but were not really embedded. I did not have a very good fix then because it is hard for us to detect (easy for Outlook itself though) so there might be more special cases where this happens.

Have you used a very old version (< 3 ) to create the directory? I know you said that you are currently using Gpg4win-3.1.5 but maybe you have used an older version to create the archive.

The cyphered directory is a Windows 10 directory.

In the past we had a problem that Kleopatra would not see the errors from the archive program but that was fixed some time ago. The Archive problem had problems with non ASCII filenames but nowadays it only has problems with full unicode filenames and those errors are shown in Kleopatra.
