Hi Loic,
I thought I had it a couple of times. We did have to move our Qt distributaion
to a new disk a month or two ago which may be the cause of some of these
problems. The cmake QT_QMAKE_EXECUTABLE path was probably stale. I thought I'd
try enabling BUILD_QtDialog in the cmake configure to see if that would help. I
found that the path in the OSG cmake configuration was stale and said {former
location path}-NOTFOUND. While fixing these things may ultimately help the
same problem remains -- Unknown CMake command "QT4_WRAP_UI".
Prior to trying your new CMakeLists.txt file I noticed something very odd.
Using ccmake and looking at my configuration for cmake-2.6.2 I move the cursor
to QT_QMAKE_EXECUTABLE and see a message "QT_QMAKE_EXECUTABLE: Path to a
program." Doing the same thing with my OSG configuration I see a message
"QT_QMAKE_EXECUTABLE: Invalid qmake found" for *exactly* the same path. Hmmmm.
Following your suggestions now --
1) QT4_WRAP_UI appears in my cmake man page. Your usage seems consistant with
the doc.
2) I tried your new CMakeLists.txt and got the messages:
QT4 was not found
QT3 was not found either
I experimented and found that QT_FOUND is true and osgviewerQT will still build.
3) FIND_PACKAGE(Qt4) did not help.
So, the configuration recognizes that Qt exists but doesn't know what version.
Since qosgwidget is version dependent it would seem like this would be an
appropriate change for examples/CMakeLists.txt:
IF (QT_FOUND AND QT_QTOPENGL_LIBRARY)
ADD_SUBDIRECTORY(osgviewerQT)
IF (QT4_FOUND)
ADD_SUBDIRECTORY(qosgwidget)
ENDIF (QT4_FOUND)
ENDIF(QT_FOUND AND QT_QTOPENGL_LIBRARY)
Once again I thought I had it when I found a directive to specify the
desired Qt version.
$ pwd
/usr/osg/OpenSceneGraph-2.8.1.build_release
$ ccmake ../OpenSceneGraph-2.8.1 -DDESIRED_QT_VERSION=4
Not only did this *not* help, I can no longer make examples_osgviewerQT as
there are no longer any rules. I think it's probably time to wipe the entire
out-of-source directory and rebuild from scratch. Changing the location of
Qt was probably just too disruptive to cmake.
Sorry about the missing umlaut over the "I" in your name. I guess three dots
are too many.

Don,
Few things you could try if you aren't bored already ;-)
1) man cmake
and search for QT4_WRAP_UI
2) replace the examples/qosgwidget/CMakeLists.txt by the one attached to
this mail
when calling ccmake it will pop up a message telling whether or not QT4
was found (this could be the problem if cmake finds qt3 and not qt4 as
the macro QT4_WRAP_UI is qt4 specific)
3) if in 2) you get that qt4 was not found you can try to uncomment the
first line of the attached CMakeLists.txt but I don't know if it will help.
I hope we can solve this.
Loïc
PS: I just noticed I was replying to Don only by mistake. So it must be
hard to follow this thread for others. Sorry about that.

Loic,
I've added the new subdirectory under src/examples, edited the
examples/CMakeLists.txt as directed and the I run ccmake.
I am building out-of-source which may introduce a problem.
$ # This is the source directory
$ cd OpenSceneGraph-2.8.1
$ # Go to the out-of-source build direectory
$ cd ../OpenSceneGraph-2.8.1.build_debug
$ ccmake ../OpenSceneGraph-2.8.1
c to configure and in no time...
CMake Error at examples/qosgwidget/CMakeLists.txt:3 (QT4_WRAP_UI):
Unknown CMake command "QT4_WRAP_UI".
It's likely that the cmake I'm using was build before Qt was installed.
I'm starting to think that this is probably the cause of the problem.

Don,
Honnestly I have no idea why you get this error. Did you compile
the example as part of osg or as a stand alone application? You
have to run cmake from the osg build directory. The fact that
the name doesn't start with osg doesn't matter as you specify in
the OSG/examples/CMakeLists.txt file :
ADD_SUBDIRECTORY(qosgwidget)
then you just have to compile by calling (from the osg build
directory) :
make example_qosgwidget
Did someone else tried to compile it? Robert?
At least it works at my place

I also wonder if there are other compliance issues with
placing this in
the osg/examples branch as every other example starts with
"osg". If
you have the time and energy to get this Robert ready, got
for it!

Hi Don, any news from you?
BTW, aren't there interested users in commenting Don's
work. I'm
a bit surprised as I've seen recently threads from users
expecting better integration of osg in QT applications. Maybe
worth posting about it on osg-users ML?
Cheers,

Don,
you're perfectly right, you need to put it i the
osg/examples
directory and add the directive :
ADD_SUBDIRECTORY(qosgwidget)
in osg/examples/CMakeLists.txt
It is totally possible to write a CMakeLists.txt for a
stand
alone
application (linked against osg libs). But, as Robert
seemed
to have
a preference for the other way around, I sticked with it.
Anyway if
you want the stand alone version just let me know.
friendly,

Hmmm. I had someone with both OSG and cmake expertise
look at
the qosgwidget

does this
imply that in order
