Hi,<br><div class="gmail_quote"><br>Thank you for the suggestion. I used dependency walker and apparently there was a problem with the MATLAB mex. The libmx.dll couldn't be found because it was not in the path and also msvcr80.dll was required. For some reason, certain C++ classes in Qt could not be located as well, amongst which were QMapData,QVectorData and QPainter. This seems to be related to an issue which has already been posted (<a href="http://www.cmake.org/pipermail/paraview/2010-March/016338.html" target="_blank">http://www.cmake.org/pipermail/paraview/2010-March/016338.html</a> , <a href="http://www.vtk.org/pipermail/vtkusers/2010-June/109514.html" target="_blank">http://www.vtk.org/pipermail/vtkusers/2010-June/109514.html</a>). <br>
<br>I have recompiled vtk with the VTK_USE_MATLAB_MEX option turned off and now I could import vtk in python. However I get an error when I try to create a vtkQtListView() object :<br><br>QWidget: Must construct a QApplication before a QPaintDevice<br>
<br>A related issue has been posted in the FAQ (<a href="http://www.vtk.org/Wiki/VTK/FAQ" target="_blank">http://www.vtk.org/Wiki/VTK/FAQ</a>), but from what I understood, this should only be a problem when you use vtk in debug while the release version is in your path. However, I only have installed the release-version of vtk, but I still get this error. Any idea where this error comes from and how I can fix it?<br>

if the module it is trying to load seems to exist (i.e. whichever one contains vtkGraphicsPython), use the dependency walker to make sure there is not a mismatch in machine type (32 vs 64) between any dlls that are loaded by the one that cannot be found<div>

Hi,<br><br>I am trying to build vtk 5.8.0 against Qt 4.7.4 with wrappings for python 2.7.2 on a windows XP system. I use MSVC 2010 as the native compiler.<br>I have build the MSVC vtk-solution in Release mode and updated the PATH and PYTHONPATH environment variables. I have installed the build in the following directory (by building the INSTALL project):<br>
<br>"C:\SciComp\vtk-5.8.0\vtk-5.8.0-msvc2010" ,<br><br>so I have added "C:\SciComp\vtk-5.8.0\vtk-5.8.0-msvc2010\bin" to PATH and PYTHONPATH and also added "C:\SciComp\vtk-5.8.0\vtk-5.8.0-msvc2010\lib\site-packages" to PYTHONPATH.<br>
<br>The build did not give any errors, but when I try to import vtk in python I get the following error message:<br><br>"Traceback (most recent call last):<br> File "<stdin>", line 1, in <module><br>
File "C:\SciComp\vtk-5.8.0\vtk-5.8.0-msvc2010\lib\site-packages\vtk-5.8.0-py2.7.egg\vtk\__init__.py", line 45, in <module><br> from vtkGraphicsPython import *<br> ImportError: DLL load failed: The specified module could not be found."<br>
<br>It seems that python cannot find the Graphics module. Does anyone know what I am doing wrong here? I have put the CMakeCache file in the attachment.<br><br><br>thanks,<br><font color="#888888">Hon Fai<br><br><br><br>
