[vtkusers] error LNK2019: unresolved external symbol "public: class vtkCamera * __thiscall vtkRenderer::GetActiveCamera(void)"

[Andreas Brüning]

Hi Carl,

did you add the libaries in your VS Project, or only the path? Add the libaries also to the Project Properties:  Linker/Input/Addiditional Dependencies. 

Maybe this will help.

Hi All,

Can anyone offer advice on fixing the link errors I'm getting (see 
below). Here is what I've done:

1) I created a build of vtk-5.0.4 using CMake 2.6 with the Visual Studio 
2008 Generator. I then successfully compiled and built a Debug and 
Release version of the ALL_BUILD target using VC++ 2008 on Vista.

2) I then successfully built the INSTALL target of the VTK solution. 
That put libraries and header files in C:\Program Files\VTK.

3) I created a new Project and Solution to see if I can make the 
Cone.cpp example from the Tutorial, Step 1. I added the header and 
library paths to my VS configuration settings by going to
Tools -> Options --> Projects and Solutions --> VC++ Directories
Platform: Win32
Show Directories For: Include Files
Show Directories For: Library Files

To the Include path, I added:
C:\Program Files\VTK\include\vtk-5.0

To the Library path, I added:
C:\Program Files\VTK\lib

Here is a listing of the library files in C:\Program Files\VTK\lib:

vtkCommon.lib
vtkDICOMParser.lib
vtkexoIIc.lib
vtkexpat.lib
vtkFiltering.lib
vtkfreetype.lib
vtkftgl.lib
vtkGenericFiltering.lib
vtkGraphics.lib
vtkHybrid.lib
vtkImaging.lib
vtkIO.lib
vtkjpeg.lib
vtkNetCDF.lib
vtkpng.lib
vtkRendering.lib
vtksys.lib
vtktiff.lib
vtkVolumeRendering.lib
vtkWidgets.lib
vtkzlib.lib

My path includes C:\projects\vtk-5.0.4\VTKBuild-MsVS9\bin\Debug\ as 
mentioned in 
http://public.kitware.com/pipermail/vtkusers/2004-April/073054.html

Any help would be greatly appreciated.
Thanks,
Carl Trapani
