[vtkusers] QVTKWidget in QTCreator - runtime error in Debug

[Michael Lynch]

Dear all,
I am having some trouble with some minimal "Hello World" code for
running qvtkwidget in debug (it works fine in release). My set up is vtk
(5.4.2) and qt (4.5.2) on Win XP. My IDE is qtcreator (1.2.1) and I am using
qmake. My VTK installation seems to be correct and I can run pure vtk code
in my ide with no problems.

The minimal code I created compiles successfully and my LIBS and INCLUDEPATH
seem to be correct. However, at runtime in debug mode I get an error which
occurs at;
widget = new QVTKWidget;

In release mode, the code both *compiles* and *runs* successfully.

VTK dlls are specified in %PATH% and I have run dependency walker on the
compiled exe and it finds all dlls.

However, I have noticed that QVTK.dll uses QTCORE4.dll and QTGUI4.dll and I
have a feeling that this might conflict with QTCORE4D.dll and QTGUI4D.dll?
Is this potentially the source of the error? And if so, how can I correct
it?

I have seen similar problems here [
http://www.vtk.org/pipermail/vtkusers/2009-March/099876.html] and a proposed
solution in VS here [
http://www.vtk.org/pipermail/vtk-developers/2008-August/005437.html] and
further reading here [
http://www.vtk.org/pipermail/vtk-developers/2008-August/005427.html].

However, I'm not sure how the solutions allow me to run in Debug mode in
QTCreator. Any help would be greatly appreciated.

Thanks in advance,

Michael
