qt opengl demos

[Bastiaan Naber <bastiaan@ricardis.tudelft.nl>]

Hi,

What packages / configuration do I need to get the Qt opengl demo's to work ? 
I have the mesademos and they compile and run quite nicely but when I try to 
compile the opengl qt demos something fails.

I have first set QTDIR to /usr/share/qt3 and then I try on 1 to the demo's 
qmake -o Makefile gears.pro

The resulting Makefile however:

all clean:
        @echo "Some of the required modules (opengl) are not available."
        @echo "Skipped."

Makefile: gear.pro  $(QTDIR)/mkspecs/default/qmake.conf
        $(QMAKE) -o Makefile gear.pro
qmake:
        @$(QMAKE) -o Makefile gear.pro

Thinks I don't have opengl. 

I have installed the following packages:

ii  libqt3-headers 3.1.1-7        Qt3 header files
ii  libqt3-mt-dev  3.1.1-7        Qt development files (Threaded)
ii  libqt3-plugins 3.1.1-7        Qt3 plugin header files
ii  libqt3c102     3.1.1-7        Qt Library
ii  libqt3c102-mt  3.1.1-7        Qt GUI Library (Threaded runtime version)
ii  qt3-dev-tools  3.1.1-7        Qt3 development tools
ii  qt3-doc        3.1.1-7        Qt3 API documentation
ii  qt3-examples   3.1.1-7        Examples for Qt3

Thanks for you help
