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&nbsp; there are problems of<br><br>error LNK2001: unresolved external symbol &quot;__declspec(dllimport) public: void __thiscall vtkPolyDataMapper::SetInput(class vtkPolyData *)&quot; (__imp_?SetInput@vtkPolyDataMapper@@QAEXPAVvtkPolyData@@@Z)<br>
