Where are you seeing pkg-config files for libgcrypt ?
The upstream project has (frustratingly) been hostile to any proposal to
add pkg-config support saying people should stick with their custom
libgcrypt-config tool
https://dev.gnupg.org/T2037
Even if this is something added by some distro downstream, what is the
benefit in using it, compared with libgcrypt-confg which should already
work & is portable.

IMHO, it could be easy for people to use pkg-config as a center to control
configurations for many different packages.
This is just an addition for qemu to be able to work in both cases. It does not
remove libgcrypt-confg and can fall back to libgcrypt-confg when pkg-config does
not work.

The addition has a maint cost associated with it, since we have have two
different ways to achieve the same thing. When only one of the approaches
is provided by upstream, the other is not going to be widely tested. In
maintaining packages in Fedora which rely on pkg-config files that are
not upstream, we've seen frequent breakage when. So my preference is
stick with what we have that is supported by upstream gcrypt.

Daniel

Resurrecting an old thread to point out that the upstream stance
seems to have changed since that discussion:
https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git;a=commit;h=97194b422bc89a6137f4e218d4cdee118c63e96e
libgcrypt 1.9.0, released almost exactly a year ago, comes with a
pkg-config file out of the box. With that in mind, I think it would
make sense to re-evaluate this patch for inclusion.

Maybe ... but we switched to Meson in between, so the patch needs to be
rewritten to use meson.build instead, I think. Also it seems like version
1.9 is not available in all distros yet, so someone needs to do an
assessment whether the distros that use an older version of libgrypt provide
a .pc file or not...

Comes back to my question of what is the benefit of using the .pc file
when what we have already works and is known to be portable.
When using meson there is essentially zero burden to using the
libgcrypt-config approach, because that's all handled transparently
by meson. This is different from the situation with configure,
where libgcrypt-config required extra work on our side.
Overall I don't see any need to change it.

Daniel

Right. I didn't mean that the patch should be merged as-is, and I
wouldn't expect it to even apply two years later :)

The original approach used the .pc file where present and used
libgcrypt-config as a fallback. Once QEMU stopped targeting all
operating system that have libgcrypt < 1.9, the fallback path could
have been dropped.

I didn't realize that was the case! I see now that Meson implements
special handling for libgcrypt, which is very nice indeed :)

IIUC, the fact that the call currently looks like
gcrypt = dependency('libgcrypt', version: '>=1.8',
method: 'config-tool', ...)
means that Meson will not use the .pc file even when it's present. I
think changing method to "auto" would cause it to use the .pc file
when it's available, which is likely a better behavior.
