QVTKWidget Error!! Please Help

  • Hello All,

    I got the VTK 5.6.1 successfully installed on opensolaris along with the QVTK widget. Also when I tried to run the Qt project which uses QVTKWidget on Linux(UBUNTU) it was successful and i could see the output. When I try to run the same code(with required changes made for the solaris system)
    I m getting the following error.

    Undefined first referenced
    symbol in file

    ld: fatal: symbol referencing errors. No output -----written to vtk
    make: *** [vtk] Error 1

    Please help me with the changes that i have to make.
    Awaiting your reply.

  • I had to link the other libraries as well. I got it built. But when I run the application file It says segmentation fault(Core Dumped) . But I don see anything wrong with the pointers or anything that I have used.
    Also when I include the (LIBS += -L/usr/local/lib/vtk-5.6 -lQVTK -lvtkRendering -lvtkIO -lvtkFiltering) .... in the .pro file I have this problem. Though I am not using any of its classes(QVTKWidget etc..,) But if I comment that line it works fine.

    Its a run time error and is related to the Shared Libraries.

    I have also set the LD_LIBRARY_PATH!!!

    What Might have gone wrong.

    I am totally stuck, Please Hel

  • Hello folks,

    i don't if the problem is sovled right now but i have the same Problem using QVTKWidget with QT!
    I'm using QTCreator Version 4.8.0 an VTK version 5.8.
    So i created a small an simple Application under WIN7 x64 and put in the *.pro file the INCLUDEPATH of VTK (INCLUDEPATH += "C:\VTK5.8.0\include\vtk-5.8") and all LIBS of the vtk which are in the folder "C:\VTK5.8.0\lib".
    I build it successfully!
    After that i added a Widget in my application and promoted that to QVTKWidget. But now when i would like to build the hole program i get a error that i don't know what to do with that.

    This is it:
    _mainwindow.obj:-1: error: LNK2019: unresolved external symbol "public: __thiscall QVTKWidget::QVTKWidget(class QWidget *,class QFlags<enum Qt::WindowType>)" (??0QVTKWidget@@QAE@PAVQWidget@@V?$QFlags@W4WindowType@Qt@@@@@Z) referenced in function "public: void _thiscall Ui_MainWindow::setupUi(class QMainWindow *)" (?setupUi@Ui_MainWindow@@QAEXPAVQMainWindow@@@Z)

    Can anyone please help me with that error? Any suggestions will be great!
