[Kde-games-devel] Build failed in Jenkins: libkdegames_frameworks_qt5 #1

[Ian Wadham]

Hi all,

It appears that "porting" a game to Frameworks and committing it is not
(yet) the same as getting it built centrally and readied for release… :-(

And this report from KDE CI seems to show that libkdegames ported to
Frameworks has not previously been built centrally.

Indeed, I am rather mystified as to how the ported version of Bovo
actually got built and tested…

This all blew up because I suggested using Bovo as a first app to
try to build and run on the Apple OS X CI (currently under devel),
thinking it would be a nice simple app with immediately checkable
output when it first builds and runs (Bovo runs an animated demo).
Sorry, guys… :-(

But see my detailed diagnosis and proposed remedies below… :-)

Jenkins needs to be equipped with the OpenAL library.

But who do we tell? "KDE CI System <null at kde.org>" seems
a rather unpromising address… :-)

I think it is high time we made OpenAL MANDATORY in libkdegames.

It has had about 3 years as optional now, and Phonon has not had a
good track record with games...

I do not understand these later errors.  Libkdegames HAS been built OK
by my KDE-Mac mailing-list friend, Marko Käning, on the (being developed)
Apple OS X Jenkins CI, after I clued him in to install OpenAL and libsndfile.
I think someone has also built it OK with Linux and new Plasma.

Libkdegamesprivate, IIRC, contains obsolescent or obsolete KDE Games
classes and (IIRC) any game still using them is supposed to clone the source
(or something like that).  Maybe it is time to DELETE libkdegamesprivate…
