I tested xenial with gcc-5.3 (xenial distro repo) and gcc-5.4 (xenial-updates distro repo) and libgcrypt 1.9.0 from git repo and from tarball. I did not get any errors.

See T5267: Ed25519 backward compatible private key support for preceding ZERO(s) for the fix.

In the next few days I'll be able to boot into Leopard, Mac OS X 10.5.8, to test this. Right now it seems that I need to fix a few problems with updated software sources…

Thanks, I already tested it this morning before your last commit and it worked as expected with my configured groups. Even the autocompletion worked nicely.

Groups (for now only groups defined in gpg.conf) can now be selected as recipients for file encryption (and for plain text encryption via the Notepad). Please have a look.

Done. The groups defined in gpg.conf are now used by Kleopatra.

Thank you for your testing.

@werner hi. I do not seem to be able to open a bug report so I submitted this fix for a typo here. Hope it is fine. Can you check if there is something wrong with my account or configuration that I can not submit bug reports? It gives me

Am I allowed to publish the patches for MacPorts?

To support old macOS (< 10.12), I think that code should be something like this:

After libgcrypt 1.9.0 first built on Tiger and 'make check' succeeded I ran 'make clean' and applied the changes to random/rndlinux.c. A simple make succeeded without problem. 'make check' then ran into problems, spitting out many times messages messages like these:

With these two patches libgcrypt 1.9.0 built on PPC Tiger, Mac OS X 10.4.11. 'make check' succeeded.

Push the change.
For older versions of MacOS X, I'll handle it later.

https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man2/posix_spawn.2.html dated August 9, 2007.
So, I guess that posix_spawn became available in MacOS X Leopard (10.5).

I don't know when the symbol of getentropy was available on macOS.

@ballapete Thank you for testing.

Also support older MacOS X, which has no posix_spawn.

Thanks @aheinecke for fixing my fix with 2859edd! Closing here.

I am going to check whether I need it on Tiger!

I tested building on Ubuntu 8.04 (gcc-4.2) and got same error about cipher_bulk_ops_t. Applying patch fixed that problem.

I see now my mistake: I also have to re-write line #132 which I did not see yet!

With your other patch I still get:

Thanks for testing. However, I do not believe patch has been correctly applied.

The "Portfile" that conducts the build process has the patch contained, I sent you the list of files being patched, and here is the end of my translated patch set:
