Hello Dave, David and Diego:<br><br>I stopped the compiling for several days.

One thing you can do is add your vtk\bin\debug directory to your PATH. You can also do this from within visual studio by going under Properties to your project and then go to Debugging. On that tab there is the Environment setting that you could set something like PATH=PATH;c:\vtk\bin\debug for example.<div>
<br></div><div>Hope that helps.<br><br><div class="EC_EC_gmail_quote">2009/3/30 吴磊磊 <span dir="ltr"><<a href="mailto:wu-leilei@hotmail.com">wu-leilei@hotmail.com</a>></span><br><blockquote class="EC_EC_gmail_quote" style="padding-left: 1ex;">

Hello David:<br><br>Yes, in the project properties, there is the additional library directories. Maybe there is some problems during the vtk installation, I am checking that. Thanks.<br><br>Ciao,<br>Leilei<br><br><hr>Date: Mon, 30 Mar 2009 10:53:21 -0400<div>

<br>I don't use windows, so I don't know about these dll's, but it sounds like you may not have the compiler set to check that directory for files to link to (the -L flag in gcc). I'd bet you have to add the c:\... \vtk\bin\ folder to a list somewhere in the visual studio project properties.<br>

Hello David:<br><br>Yes, I missed the vtkRendering. Then I met the other problem, during the debuging, "This application has failed to start because vtkRendering.dll was not found. Re-installing the application may fix this problem". Actually the vtkRendering.dll is in the \bin\debug or \bin\debug. Do you have further ideas on this problem. Thx.<br>

Hello All:<br><br>My name is Leilei Wu, and I got some problems when compiling the codes related with VTK in visual studio 2005, both in release and debug mode. (I used visual studio 2003 before, there was no this kind problem)<br>
<br>In the code PART1 (see below), the compiling is ok, but in the code PART2 there are problems of<br><br>error LNK2001: unresolved external symbol "__declspec(dllimport) public: void __thiscall vtkPolyDataMapper::SetInput(class vtkPolyData *)" (__imp_?SetInput@vtkPolyDataMapper@@QAEXPAVvtkPolyData@@@Z)<br>
error LNK2001: unresolved external symbol "__declspec(dllimport) public: static class vtkPolyDataMapper * __cdecl vtkPolyDataMapper::New(void)" <br>(__imp_?New@vtkPolyDataMapper@@SAPAV1@XZ)<br><br>================================<br>
code PART1:<br> vtkContourFilter *VesselVolume = vtkContourFilter::New();<br> VesselVolume->SetInput( connector->GetOutput() );<br> VesselVolume->SetValue(0,255);<br><br>&n
bsp; vtkSmoothPolyDataFilter *SmoothPolyDataFilter = vtkSmoothPolyDataFilter::New();<br> SmoothPolyDataFilter->SetInput( VesselVolume->GetOutput() );<br> SmoothPolyDataFilter->SetNumberOfIterations( 175 );<br>
<br> vtkPolyDataNormals *NormalsPolyData = vtkPolyDataNormals::New();<br> NormalsPolyData->SetInput( SmoothPolyDataFilter->GetOutput() );<br> NormalsPolyData->FlipNormalsOn();<br><br>code PART2:<br> vtkPolyDataMapper *PolyMapper = vtkPolyDataMapper::New();<br>
PolyMapper->SetInput( NormalsPolyData->GetOutput() );<br> int colormode = PolyMapper->GetColorMode();<br>=================================<br>with the vtk header files of <br><br>#include "vtkImageWriter.h"<br>
#include "vtkImageData.h"<br>#include "vtkImageViewer.h"<br>#include "vtkRenderWindowInteractor.h"<br>#include "vtkDataSetMapper.h"<br>#include "vtkPolyDataMapper.h"<br>#include "vtkRenderWindow.h"<br>

=================================<br><br>Can someone give me some solutions (sorry if there are solutions already on the vtk users board)? Thank you very much!
