[KPhotoAlbum] problems compiling KPA on Ubuntu 16.4 (LTS)

[Andreas Schleth]

Hi Johannes,

in your build instructions you mention "Ubuntu" without naming a release ...

My daughter is trying to install KPA on a freshly installed Ubuntu 16.4
LTS and has a few problems - see attachments. The build fails when
trying to use a QT function that was introduced in QT 5.6. Is there an
easy way to fix this?

Or, alternative solution: which is the latest version that compiles on 16.4?

Andreas











Crazy shit! Weißt du, warum ich kphotoalbum nicht kompilieren konnte? In
Ubuntu 16.04 ist eine veraltete Version von Qt installiert, die bei
einer Klasse eine Methode nicht kennt... Ich konnte Qt 5.6 manuell
nachinstallieren, aber der Fehler ist immer noch da. Ich suche mir mal
eine Àltere Ausgabe von kphotoalbum.

Hi Andreas!

Version 5.0.1 didn't have this code yet; it would be a bad idea to build this
version though, because we fixed a lot of (porting) bugs and regressions with
5.1.

If you can't update to a more recent Qt version, probably, you can try to
build the lastest KDE4 version of KPA? You'll probably get less bugs there.

But the real question is: why is there no packaged KPA on Ubuntu you can use
as-is?

Cheers,
Tobias

A good question indeed ;-)

As far as I know there used to be a well-maintained KPhotoAlbum PPA for
Ubuntu. I don't use Ubuntu myself, which leads me to the question:

Does anyone know the status of that package archive?

I was just about to reply that Ubuntu LTS warrants a backport from my point of
view, but then I realized that I can make the code compatible with Qt 5.5 and
make it better at the same time ;-)

Could you or your daughter try the current git master (commit 53aa2d91 or
later)?

Hi Johannes & Tobias,

thanks for the input. I just did a quick test and found the latest
version to be compilable and working - as far as I can tell with 5 quick
clicks.
So I will see what my daughter (500 km away) will manage and report on
her progress.

On a very different track: Just this week I had to fire up my old trusty
VM with opensuse 11.2 and KPA 4.1.7 to do some time shifting on scanned
slides:
a) this did work nicely with my most recent database and the database
was still OK when viewed in KPA 5.x. This is quite remarkable!
b) when using the ancient version I presently noted the different (and
better) placement of the lens on the timeline: default position on most
recent images and not (as of now) on the oldest. hint, hint ;-)

Cheers, Andreas

We try hard not to break things too often ;-)

I know, I know - I have a single image from the early 1900s, which reminds me
of this issue every time I start up kpa...

Hi everybody,

here is an update (belatedly due to pressing other business). The build
with recent git master does not stop at 12% but progresses to 60% ...

My daughter is considering an upgrade to 16.10 now.

But generally speaking:
Wouldn't it be sensible to have a build that is compilable on the LTS
versions of Ubuntu (or similar not yet totally outdated systems)?
Otherwise the user base would be limited to people living at the
bleeding edge of things.

to people living at the bleeding edge of things.

If you want to stick with LTS, use a version of kpa packaged for LTS
or at least a versioned release that's compatible with the packages in
LTS.

It's not reasonable to expect the development tip to stay long-term
back compatible with every system out there. If KPA wants to take
advantage of new features in KDE, Qt, or any other interesting new
package out there, it's going to break that compatibility.

Not everyone uses Ubuntu; asking the developers to test every
push on every variant of every OS simply isn't practical.

A Quick 'n' Dirty patch would be:

--- a/AnnotationDialog/Dialog.cpp
+++ b/AnnotationDialog/Dialog.cpp
@@ -1235,19 +1235,6 @@ void AnnotationDialog::Dialog::loadWindowLayout()
QString fileName = QString::fromLatin1( "%1/layout.dat" ).arg(

- m_dockWindow->tabifyDockWidget(m_previewDock, m_mapDock);
- // make sure the preview tab is active:

-#endif
return;
}

This brings it to what KPA 4.7.2 did there.
