Hello,
I've gotten queries like the ones copied below, in the context of my efforts to
provide co-installable Qt4 and Qt5 installations in MacPorts. See also the
outputs of qmake -query below.
I seem to recall that at some point (Qt 2 ? Qt 3?) one could hardly get away
from setting QTDIR even for running Qt applications built against a single Qt
version. The online documentation still refers to QTDIR, but the variable
doesn't appear to be set even in my Linux/KDE desktop and I haven't had to use
it on OS X either (IIRC I've even had a left-over QTDIR pointing to a Qt 3
install for a while). How up-to-date is that online documentation w.r.t. its
references to QTDIR?
Also, is it required to configure Qt with a single -prefix=Foo for QTDIR to
make sense (see question 2 in the forwarded message below)? If so, I suppose
one could write a script that sets up a collection of symlinks in a directory
of choice so that QTDIR can be set to that "shadow bundle". Before I roll my
own, does something like that exist already?
Thanks,
René

2. IF I install qt4-mac +concurrent, what two values do I use for setting
$QTDIR to pick up either qt4-mac +concurrent or qt5-mac-devel in my
non-MacPorts development areas for KDE 4 and KF5/Frameworks?
I am still not convinced about your installation strategy [2]: in fact
I have
no idea where qt5-mac-devel has been installed. There seem to be
bits of it (links to a Library/Frameworks area) in different places
under
/opt/local.
...
Why cannot we install into something like /optlocal/qt4 and /opt/local/qt5,
or ditto, but one subdir down from /opt/local?
