Installing Frameworks alongside Cliff McDiarmid wrote:
Hi I have a working LFS systemd with Qt5 anf Qt4 under /opt. I'm
presently running KDE 4.14.3. Would it be possible to run KDE
Frameworks and Plasma from /opt after invoking the right Qt? A lot
of the packages required obviously have to be linked to Qt5, but
also to Qt4, if I'm to keep my present setup as well. Would this
work? thanks
There are no conflicts in the Qt4/Qt5 or KDE4/KF5 libraries. Just
add the appropriate directories to /etc/ld.so.conf and run
ldconfig. There are conflicts with qt4/qt5 binaries like qmake when
building apps that need them. Use the set-qt4 or set-gt5 scripts
(source them to set PATH properly) as needed when building Qt based
apps.
I believe that KDE calls their desktop Plasma but in the KDE4 tarballs,
it is not named separately but included in things like kde-runtime. So
it's not incorrect to call KDE4's desktop Plasma4. They separated it
out for KF5/Plasma5.
If that's not right, please let me know.
Many thanks. So a package, if I understand you, like Phonon, would
not run with Qt4 under KDE4, and then with Qt5 under Plasma on the
same system as it cannot be built with both.
I assume one would have to install a version of it under /opt/kf5?
Yes, that's what I do.
