A while back, I did have multiple versions of QT's on a machine. The only
thing it would work for me (either runtime, or development) is I have to run my
own shell command to setup the proper PATH, and LD_LIBRARY_PATH:
. /home/userid/bin/setEnvQT451.bash
or,
. /home/userid/bin/setEnvQT471.bash
Note the "." at the start of the command, which will take effect in the current
command-shell (at least with Bash shell). I don't remember if QT_DIR, or QTDIR
was needed, so I set both.
The following example of /home/userid/bin/setEnvQT471.bash , I also have my
own, separate copy of QtCreator 2.0.1, :
#!/bin/bash -x
export QT_DIR=/home/userid/compile/qt-4.7.1
export QTDIR=/home/userid/compile/qt-4.7.1
export QMAKESPEC=${QTDIR}/mkspecs/linux-g++
PATH=/home/userid/compile/qt-4.7.1/bin:$PATH
LD_LIBRARY_PATH=/home/userid/compile/qt-4.7.1/lib:$LD_LIBRARY_PATH
PATH=/home/userid/compile/qt-creator-2.0.1/bin:$PATH
LD_LIBRARY_PATH=/home/userid/compile/qt-creator-2.0.1/lib:$LD_LIBRARY_PATH
export PATH=$PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH
##
So after running
. /home/userid/bin/setEnvQT471.bash
from the command line, I keep that command line to launch
qtcreator &
or my QT-runtime app, which works with the specific PATH, LD_LIBRARY_PATH I
need for that version of QT.
Similar usage could be done for multiple runtime environments (if I want to run
multiple versions of my own app separately).

Most folks keep only one copy of Linux installed on their system. Upgrading
would be a huge pain, and potentially be crippling for a few days (even 1-2
weeks) while configuring the new installation. The more important apps get
used first, and less important apps may not get used until a week or two later
and need time to tweak...
My way around that is to have a separate partition of about 20-30 GB of space
for each Linux installation (full install, not using separate /home mount
point). So each copy of some some Linux variation, or version could function
independently. This way, I can switch to my old installation when I needed
something done right away. In the mean time, I can take my time to tweak some
newly installed Linux distro, or version at my own pace, I can mount the other
installed Linux partitions as read-only so I can even compare configuration
files, like
/etc/security/limits.d/audio.conf
Of course, I keep data files in its own partition(s), and mount those
partitions from each Linux install (at boot time, or as needed).
I have used such setup when I need to try "distro hopping", or when I want to
try a new version of my preferred distro. It helps me quite abit. Of course,
I have to be mindful of which partion has which Linux flavor and version.
Perhaps this kind of setup would help some folks out there. It doubles as my
"instant backup" if I messed up in one Linux partition, I can boot up to the
other Linux partition, which has all my apps already installed and configured.
May not be too practical for older laptops because of limited diskpace, but
works well if you can spare the disk space. Enjoy.

There are tons of pages on the wiki that date back to a time when we had a lot of people working here, and a lot of momentum. We had huge dreams for what we were just about to accomplish in the near future, but then... Well, things just changed gradually over time. It's a long and complex story, but it ends with Rosegarden as an old project that's hobbling along on a walker.

I surely won't upgrade my perfectly running system :-) I have been bitten by that too often, and will rather migrate to a newly installed newer version in time.

[Rosegarden-user] Compiling V11.06 with Qt 4.5.3 Fails
Hello, I'm trying to compile version 11.06 on my Ubuntu Karmic (9.10) machine, which has Qt 4.5.3 installed. I experience the following build errors: src/sound/Tuning.cpp:89: error: ‘class QXmlStreamReader’ has no member named ‘readNextStartElement’ src/sound/Tuning.cpp:168: error: ‘class QXmlStreamReader’ has no member named ‘skipCurrentElement’ src/sound/Tuning.cpp:179: error: ‘class QXmlStreamReader’ has no member named ‘skipCurrentElement’ src/sound/Tuning.cpp:194: error: ‘class QXmlStreamReader’ has no member named ‘skipCurrentElement’ src/sound/Tuning.cpp:214: error: ‘class QXmlStreamReader’ has no member named ‘skipCurrentElement’ src/sound/Tuning.cpp:226: error: ‘class QXmlStreamReader’ has no member named ‘skipCurrentElement’ Reading the documentation on both members, it seems that they have been introduced in Qt 4.6. The wiki page states that Qt 4.4.3 is needed (version 4.5 is suggested). Is that no longer true?
