[vtkusers] vtkPowerCrustSurfaceReconstruction unresolvedexternal symbol

Thu Apr 5 16:41:38 EDT 2012

Bill,

That successfully resolved all of the compiling errors.  When I ran my program (TPS) I got another error: "Cannot find vtkHybrid.dll, you may need to re-install the program".

I was able to find this file in the bin\debug folder.  I am re-building vtk to see if this resolves the issue.

Thanks,

Chris

If the class in in Hybrid it should have
VTK_HYBRID_EXPORT
