digikam: update to 8.4.0

[mascguy (Christopher Nielsen)]

It looks like our Digikam port is a few major releases behind. And it's also failing to build across-the-board on our buildbots.

Let's update to the latest release, if possible.

According to rumors, Rene may have a working Digikam 7.1.0 port already... ;-)

[RJVB (René Bertin)]

Much easier said than done, alas. At least the way I build and install my KF5 stuff but even if I didn't try to get feature parity with Linux builds there would still be a sh*load of dependencies to introduce first. Here's a pruned list allowing to focus on non-existant ports (kf5-*):

The following ports are dependencies of kf5-digikam @7.1.0_0+langselect+qt5kde:
  xz

Personally I have given up on the idea of introducing KF5 to MacPorts - I'm not even maintaining my own ports very actively anymore.

Gilles himself probably has experience building a standalone version using a script he might be able to tweak so Qt5 and other dependencies are taken from MacPorts but the KF5 frameworks and libraries are embedded in the app bundle.

Hi,

Mostly the list of dependencies is out of date. As i can see libkipi libkexiv2 for ex, are removed since few years now.

Look here to see the dependencies list of digiKam :

​https://www.digikam.org/api/index.html#externaldeps

And yes, the current MacOS PKG installer is fully compiled with Macports. This include KF5 of course. My scripts are located here :

​https://invent.kde.org/graphics/digikam/-/tree/master/project/bundles/macports

This is the macports packages list installed to compile digiKam :

​https://invent.kde.org/graphics/digikam/-/blob/master/project/bundles/macports/01-build-macports.sh#L270

... and here, the list of KF5 components installed in Macports:

​https://invent.kde.org/graphics/digikam/-/blob/master/project/bundles/macports/02-build-extralibs.sh#L72

The script 03 compile and install 3 shared UPSTREAM libs (libexiv2, lensfun, libqtav), digiKam, and 2 stand alone plugins.

The script 04, scan dependencies to build the PKG installer, drop debug symbols, make binaries relocatable, and package the application.

To process packaging from scratch, this take 4 hours on my macbook pro 2015 Intel.

Voilà, If you need more guidance, let's me hear...

Replying to cgilles:

I have built now 4.14.0, however it crashes on launch (like many KDE4 apps, though not all of them):
