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.
Best,
dp

Responding to self:
I found an article on Google that states it's a safe install, but I'm
still interested in actual use-case reports.

i am not sure if it applies for Fedora, but here in Gentoo/Sabayon land i have Qt 4&5
coexisting harmoniously. hope that helps.

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.

Hi Rui,
So far, so good. I installed it on F19, built & installed the latest
SC3, and have been enjoying SuperCollider examples for the past hour.
Are your Q* applications and utilities Qt5-aware ?

absolutely
all of them with no exception are "qt5-ready" for years now
however, there's this mentioned "lv2-ui/(lib)suil clause" which applies
to qtractor when built on qt5: most non-qt5 lv2 plugin guis won't work
there, unless they implement the lv2-show/idle interface, as is the
(probably single) case of the calf suite (last time i've checked :))
no worries. for the time being though: most distros go with (all my)
qstuff on qt4. still the recommended runtime base.
cheers
