[vtkusers] Link Problem with VTK - QT

[oli]

Hi,
thanks for response, I have found on this link a good information: to use QT_DLL, UNICODE, QT_THREAD_SUPPORT in the precompiled arguments.
With this line I can link the vtkhandqt solution without problem, but It is strange because the other solutions (even kuebler solution) give the same linking problem... It's strange but one runs, therefore It's ok.
If anyone can explain me the reason of theses problems, I'm still interested.

  I have no ideas how to solve these problems but you might want to
  try another vtk-Qt-package, which is provided by Carsten Kuebler:

  http://wwwipr.ira.uka.de/~kuebler/vtkqt/index.html

  I'm using VTK4.0 and Qt2.3 under windows together with this 
  package and it works fine. It is very easy to handle and probably
  the very latest package bringing VTK and Qt together.

    Hi,
    I'have tried two librairies packages that integrate VTK RendreWindow in a QT Widget. These librairies are vtkqt http://www.matthias-koenig.net/vtkqt/  and vtkhandqt http://www.medres.ch/~jstifter/vtkandqt/ . 

    I use QT2.3 and VTK4.0, and I runs without problem programs that use VTK or KT. 
    But I cannot use these librairies, VisualC++ compiles but I get errors at linking:

    So Have you an idea?
    thanks
