我想手动画一个Handle添加到一条线上，结果报错了，而我检查库的包含，所有的.lib库我都配置进去了。所以不知道是怎么回事了...
错误信息：
---------------------------------------------------------------------------------------
VtkLineHandle.obj : error LNK2019: 无法解析的外部符号 "__dec

代码如下：
//LineHanle
vtkSmartPointer<vtkLine> line1 = vtkSmartPointer<vtkLine>::New();
line1->GetPointIds()->SetId( 0, 0 );
line1->GetPointIds()->SetId( 1, 1 );
vtkSmartPointer<vtkLine> line2 = vtkSmartPointer<vtkLine>::New();
line2->GetPointIds()->SetId( 0, 1 );
line2->GetPointIds()->SetId( 1, 2 );
vtkSmartPointer<vtkLine> line3 = vtkSmartPointer<vtkLine>::New();
line3->GetPointIds()->SetId( 0, 2 );
line3->GetPointIds()->SetId( 1, 3 );
vtkSmartPointer<vtkLine> line4 = vtkSmartPointer<vtkLine>::New();
line4->GetPointIds()->SetId( 0, 3 );
line4->GetPointIds()->SetId( 1, 0 );
vtkSmartPointer<vtkCellArray> cellArray = vtkSmartPointer<vtkCellArray>::New();
cellArray->InsertNextCell( line1 );
cellArray->InsertNextCell( line2 );
cellArray->InsertNextCell( line3 );
cellArray->InsertNextCell( line4 );
vtkSmartPointer<vtkPolyData> polyData = vtkSmartPointer<vtkPolyData>::New();
polyData->SetLines( cellArray );
vtkSmartPointer<vtkPolyDataMapper> lineHandleMapper = vtkSmartPointer<vtkPolyDataMapper>::New();
lineHandleMapper->SetInputData( polyData );
vtkSmartPointer<vtkActor> lineHandleActor = vtkSmartPointer<vtkActor>::New();
lineHandleActor->SetMapper( lineHandleMapper );

在确认一遍，少一个lib

或者是lib路径改成绝对路径试试

我去，我又遇到它了。还是不知道咋弄。。。
