Hi David and everyone,<br><br>Yes, it works. No more unresolved external symbol errors about vtkPCAStatistics happens. However, there are more other unresolved external symbol errors.<br><br><b>1. bool __cdecl rmatrixsvd(class ap::template_2d_array<double,1>,int,int,int,int,int,class ap::template_1d_array<double,1> &,class ap::template_2d_array<double,1> &,class ap::template_2d_array<double,1> &)<br>
2. void __cdecl ap::afree(void *)<br>3. void __cdecl ap::vmove(double *,double const *,int)<br>4. void * __cdecl ap::amalloc(unsigned int,unsigned int)<br></b><br>All of them are about template_1d_array or template_2d_array. And I used vtkDoubleArray to recieve the return value of vtkPCAStatistics::GetEigenvector();<br>
<br>I've narrow it down to vtkPCAStatistics::New(). Maybe something wrong with it when the instance created?<br><br>Can anyone give me some suggestions? Many thanks in advance.<br><br>Best wishes<br>Wenlong<br><br><div class="gmail_quote">

</div>You don't just need to add the include directory, you actually have to<br>
link to the library 'vtkInfovis'.<br>
