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.

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

Finally came around to check this.
On Fedora with Kleopatra 25.04.03, gpg 2.4.5 and pinentry 1.3.1 the pinentry window ist above the Kleoaptra windows.

Looks good to me on gpg4win-5.0.0-beta357 @ win10

Pushed the changes in {gniibe/synch-spawn} branch.
It consists of three commits:

• rGb8b8afc5cf6f: build: Require libgpg-error 1.56 or newer.
• rG15b8bc7495db: w32: Synchronous spawning gpg-agent/dirmngr/keyboxd.
• rG6bd6826aa6ff: common:w32: Care about the NUL device for start_new_service.

Ok, thanks. I pushed the powerpc patches to master.

tested with Gpg4win-5.0.0-beta357 (GnuPG 2.5.11):

I can confirm that the crash is fixed by the change.

Urgs

I pushed the longlong patch: rCb61a7661d017: mpi: Provide the function prototype of __udiv_qrnnd.

The card returned these 32 bytes:

1883ba0d1cacda6f357ad9caa062ebd7b3a07291a7788565caf38973bf414286

agent_card_pkdecrypt however returned 33 bytes:

411883ba0d1cacda6f357ad9caa062ebd7b3a07291a7788565caf38973bf414286

Thus the indicator byte is 0x41. The specs (librepgp, rfc4880bis) say:

We have now improved error messages, and this, combined with what could be considered a setup issue, I think we can consider this done for now.

IIUC, it's actually binutils version dependency (instead of GCC 15), perhaps.

I tested Ubuntu's version of GCC-15 (powerpc64le cross-compiler) and did not see this build failure:

I figured out that .machine "any" is needed with GCC 15.

In short: A message was saved as an encrypted draft and then the user edited that draft, disabled encryption and then the message was sent out only encrypted to the draft key.

We won't implement that any time soon given that gpgol2 will be an easier plaform to get it right.

Thanks. Will go into 2.4.9 to be released soon.
