The reporter in the forum originally wrote:

We need a better error code from gpg to change this

We decided that gpg should emit a status message for success, too.
gpgme should then look for that status message instead of only absence of error.

Fixed by adding a patch for Qt 6 (and a patch for Qt 5 in gpg4win-4-branch for VSD 3.4).

A quick check with passing ASSUAN_PIPE_CONNECT_DETACHED does not changed anything.

I wonder whether rA3bccb33ccd9028ff505d9979fd6c8a37393b892d which changes Assuan's waitpid function for Windows is well aligned with the my_waitpid in gpgme's assuan-support.c (which does nothing). gpgme creates a detached process in most cases but for gpgsm assuan_pipe_connect is used without the ASSUAN_PIPE_CONNECT_DETACHED flag.

Another data point is that the faulty versions use libassuan 3 with a slightly changed API. May one of the follwing chnages cause the problem?

Although in VSD 3.2.2 we get no warning when configuring S/MIME debugging wrong we then get a nice message "Configuration error" when trying to encrypt with S/MIME, instead of gpgsm hanging without any message at all:

Logging all

Someone should test whether gpgol2 is able to reencrypt all subfolders of a given folder. The file reencrypt tool (current name "recipients" "hugh") does this already.

The patch above is wrong for if (!rc) last_err = rc;, the condition should be (rc).

It's in master (to be 1.12), then, it's backported to 1.11.2, which is confirmed build well.
So, closing.

Thanks for testing.

Hello,
thank you all. I can confirm that 1.11.2 builds successfully on ppc64el with gcc-15 (Debian sid + experimental). Lacking access I have not be able to check alpha. I would suggest closing this report as fixed.

The issue also occurs in VSD-3.3.2 and 4win-4.4.1 but not in VSD 3.1.26

works in vsd3.3.3, tested with VS-Desktop-3.3.90.8-Beta

OK on Linux now with new enough versions (Fedora 42).
