[vtkusers] How to step through vtk source code

[yqtan2003 at sohu.com]

Hello everyone.
    I want to step through vtk source code to see how the render process works, but I just couldn't make it. I have searched the archive, and the recommendations there couldn't help.
    I am working with vtk4.2. One suggestion in the archive is to use debug version of vtk dll, and I do use the debug version. Another suggestion is to add the files to the project workspace, but this didn't help. I got link error lnk2005, which indicate that the static New function is multiply defined.
    To debug vtk library, I use the cone application at Examples\Tutorial\Step1\Cxx\cone.cxx in vtk source code.
    Thanks in advance.
