Oh, well. So I guess the FreeBSD port for Digikam fails to list a

Building KDE workspace

A little grep'ping in port plists hints that the missing dep

Executive summary: you cannot build KDE libraries (such

kfilemetadata fails to install. That file is indeed missing; the staging area

does however contain a libkfilemetadata.so.4.14.2. So why does the source package

of 4.14.3 generate a 4.14.2 library?

Conclusion: the build dependency for kfilemetadata should list the exact same version of
|
|
|
|
|
kdelibs, or the port won't build.
|
|
|
|
|
|
|
|
|
|
So, we now need to upgrade kdelibs in order to be able to build kfilemetadata, which
|
|
|
|
|
is a dependency of kde4-workspace, which is an unlisted dependency of Digikam.
|
|
|
|
|
|
|
|
|
|
Rebuilding kdelibs from sources involves a portmaster operation that will on this
|
|
|
|
|
system rebuild a few hundred depedencies, so doesn't sound like an attractive option
|
|
|
|
|
(too big a build to babysit, with likely hiccups on the way, and in any case too
|
|
|
|
|
much of an earthquake with so many ports being updated at once.

Side note: hey, couldn't I just install kde-workspace from packages as well? Well,

for some reason pkg wants to remove my TeXlive install, and upgrade two dozen other
|
|
|
|
|
packages, so thanks, but no thanks. (I would have gone for it were it not for the
|
|
|
|
|
removal of TeXlive. But that's too much breakage to fix downstream.)

Now Digikam displays its splash screen and starts initializing, then segfaults.

Hell, I'll have to bite the bullet and upgrade a few hundred packages from ports. :-(

The vlc port by defaults depends on QT5, whereas the rest of the
|
|
|
|
|
KDE system depends on QT4. You can rebuild vlc with the QT4 option,
|
|
|
|
|
but that's not quite sufficient: actually phonon (part of KDE)
|
|
|
|
|
depends explicitly on slave port vlc-qt4 (so you can't just install
|
|
|
|
|
vlc with QT4 option, you have to go through the separate slave
|
|
|
|
|
port).

OpenSLP

|
=======
|
|
|
|
|
|
|
|
|
|
Digikam does not segault anymore, CUPS is repaired (I had to reinstall
|
|
|
|
|
it somewhere in the process, as it would silently fail to startup
|
|
|
|
|
due to a missing symbol) but I still cannot delete photos. On second
|
|
|
|
|
guess, the missing item might be kde4-runtime, not kde4-workspace.
|
|
|
|
|
|
|
|
|
|
Here the dead end is quickly reached: x11/kde4-runtime depends on net/openslp,
|
|
|
|
|
which won't build because of a security vulnerability... Oh well, let's
|
|
|
|
|
build with `DISABLE_VULNERABILITIES=yes`...
|
|
|
|
|
|
|
|
|
|
(It's beyond my understanding why `-w`, i.e. "Keep old shared libs in the hope of not rendering
|
|
|
|
|
other applications unusable" is not the default)
|
|
|
|
|
Epilogue
|
|
|
|
|
========
|
|
|
|
|
|
|
|
|
|
As a corollary, I'll have to upgrade to GnuPG 2.1 (dependncy of `security/gpgme`) -- I had so
|
|
|
|
|
far carefully stuck with `security/gnupg20`.
|
|
|
|
|
At long last, small victory: the missing piece was indeed x11/kde4-runtime.
|
|
|
|
|
The problem has been `reportd <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203222>`.
|
|
|
|
|
I must admit I'm getting sick and tired of the amount of breakage I need to
|
|
|
|
|
investigate and fix most times I want to install something using the ports system.
|
|
|
|
|
Desktop work nowadays requires humongous dependency closures that are extremely
|
|
|
|
|
fragile, and I'm very much tempted these days to switch back to Debian for that.
