Hi Robert,
A rebuild today was quick to flag that JPEG and TIFF components were missing.
This was quickly fixed by installing the development tools for both.
(This system was Windows-XP until recently designated to take over
for my departed linux box.) This solved the problem with osglogo and
other examples that couldn't read JPEGs.
The source of the osgviewerQt problem is that I don't yet have the standard
.osgt files on my system. I hadn't noticed that OpenSceneGraph-Data had changed
since the 2.8.0 version.
Otherwise, our project has been using osg-2.9.8.

I gave 3.0.0-rc3 a check out here and found a few problems. These are
quite possibly due to the atypical setup here, particularly the farily
old version of Qt installed and possibly other factors.
system: x86_64 SuSE 11.01
graphics: NVIDIA Quadro FX 1800 270.41.19
gcc: 4.3.1
Qt: 3.3.3
The example osgviewerQt comes up with solid blue background in all
viewports and not other graphics. I'm unable to run the other Qt
examples since we don't compile for QT_QTWEBKIT_LIBRARY. We've
got Qt-4.4.3 so this could be a version mismatch.
I'm afraid I'm not Qt expert so have to rely upon members of the community
for improving the osgQt lib, however, even with those of the community who
have greater Qt skills I suspect most will be using more modern Qt versions
so might not be able to help debug your situation directly.
On the possibility of a Qt version mis-match, the thing to look at is what
Cmake has picked up. Running ccmake . in the OpenSceneGraph/ directory
and see what QT_ libs and headers it's picked up. You'll need to press 't'
in ccmake to toggle on the advanced options so you can see all the QT_
variables.
A number of other examples failed due a missing jpeg plugin. I don't
know why this is a problem and haven't invesitgated it yet. Otherwise,
the build seemed to go without a hickup and other then the problems
mentioned the examples were working.
Could you check to see if the jpeg plugin didn't compile? Could you check
what version of jpeg worked?
Also have you been using a previous version of the OSG without these problems?
If so which version?
On a very positive note 3.0.0-rc3 did quite well in the 20 year old
legacy application we've recently ported to osg.
Now that's the news I like :-)
Robert.
