    Question qwt polar dev on intrepid ubuntu??!?

    Hi,

    I'm working on qt4 project on Ubuntu Intrepid.
    installed qwt-qt4 and qwt-qt4-dev from repository
    there is not a qwt polar deb repository, so I proceed from svn repository

    qmake
    make
    make install
    all generated file are in wrong dir, make install create a /plugin/designer/libqwtpolarplugin.so in the root of filesystem!!(I've copied to the /usr/share/qt4/plugin/designer)
    also a lib dir and include dir ( I've copied to /usr/lib and /usr/include



    On qt4designer menù Help->plugin info :

    Failed plugin :
    - /usr/lib/qt4/plugin/designer/libqwtpolarplugin.so
    - the file '/usr/lib/qt4/plugin/designer/libqwtpolarplugin.so' is not a valid plugin

    reading the relative Makefile found dir of qt3 ! Is the error related to it (does not exist a qwt polar version for qt4?

    Tring to compile example I get undefined reference errors.
    I try to change the -lqwt with -lqwt-qt4
    no change


    Does anyone help me?
    do i've to remove qwt from synaptic and use only svn version?
    do u suggest to migrate to another linux distro (gentoo?) ?

    thanks,

    Paolo

    Guess you have Qt3 and Qt4 on your system and you executed Qt3-qmake by accident.

    Tanks Uwe,

    using qmake-qt4 instead of qmake all seems ok.

    It compile ,but no running :

    root@system:/usr/local/qwtpolar-0.0.3/examples/bin# ./polardemo
    ./polardemo: symbol lookup error: ./polardemo: undefined symbol: _ZN12QwtPolarPlot16staticMetaObjectE

    The same error from designer plugin.


    bye,

    WRT
