Greetings,
Is anyone here successfully running a parallel installation of Qt4 and
Qt5 ? I want to install the latest SuperCollider3 which now requires
Qt5. I'm on Fedora 19 with Planet CCRMA extensions, it's been happy with
Qt4, but now I need to consider installing Qt5. The question: Can I go
ahead and install Qt5 in parallel with the existing Qt4 ? If there are
known problems with Linux audio software perhaps someone is already
aware of them and can warn me before I take action.
I'm particularly wary of this kind of thing. I recently hosed an entire
system during a routine installation of components from the F19 repos -
yes, in certain circumstances Fedora will quietly let you destroy your
system without warning - and I'd like to avoid a repeat of that scenario.
afaik
qt4 and 5 co-existence is a non-issue whatsoever.
it only gets to be a showstopper when dealing with plugins: the host
*and* the plugin must be linked to the same qt framework level.
add to that, on the very specific niche of lv2 gui realm, (lib)suil
won't work for qt5 uis--it's rigged for qt4/x11 and only.
besides those specific issues, you can have qt5, qt4 and oldish qt3
runtime and development environments on the same system image with no
obvious problem at all.
hth.
cheers
