Sure, please, nobody should feel insulted, I just stated my opinion.

Actually, I here already disagree.
At least some KDE application developers like me or the Krita team want is to have self contained installers/bundles,
as that is the normal way to go there.

And it is not true, that all frameworks require globally installed files. I patched
KXMLGui to not require any UI file installed, itself it needs no longer any global files either.
The plugin mechanism of KDE was rewritten to not require .desktop files either, but
just have the plugins dir in the right place.

KConfig will have that fallback soon, too, to even allow preshipped default configs like in kate
without global stuff:


KIO is still a challenge, that is true.

I understand that for KDE 4 it was necessary to treat Mac just like a other kind of
BSD, but I think for frameworks we shall aim to make them usable for people wanting to
create bundles and not going the MacPorts route.

Please read:


And yes, without any black magic and any Qt patches, you can have working applications:


You need nothing to work on Kate beside XCode, Qt + CMake (and yeah, gettext).
All other stuff is just the ECM + frameworks.
Nothing else above what is shipped with a normal Mac.

The only real problem with that ATM is broken KIO without dbus, patch here:


and that I need to install the icons in the right locations.

And yeah, I think a lot more stuff is broken for sure and still we would need some
"deploy-qt" like tool to bundle all the libs inside the application bundle.

And no, I don't want to make life for MacPorts/Fink/Homebrew/... harder,
I am happy that people fix stuff for that things, too, but I don't see that as the goal
we had for the Frameworks 5 initiative.

We wanted to make them attractive for non-KDE applications & developers.
For Windows & Mac that means for me, they must be usable with stock Qt and without any
non-os native requirements ;=)
