About vtkCellArray::InsertNextCell()

Support

Why undefined error?

line->GetPointIds()->SetId(0, 0);
line->GetPointIds()->SetId(0, 1);
vtkNew<vtkCellArray> cells;
cells->InsertNextCell(line);

build information: vtk-9.1 with MinGW8.1 

Here is the compile error infomation:
CMakeFiles/LearnVtk.dir/main.cpp.obj: In function `vtkGenericDataArray<vtkAOSDataArrayTemplate<int>, int>::SetValue(long long, int)':

CMakeFiles/LearnVtk.dir/main.cpp.obj: In function `vtkGenericDataArray<vtkAOSDataArrayTemplate<long long>, long long>::SetValue(long long, long long)':

Could you display the full error for each instance? The error ends with a column, which seems to indicate there’s more to it. In the meantime, can you try:

#include <vtkTypeInt64Array.h>
#include <vtkTypeInt32Array.h>

Hi, Thanks for your reply. I’m using example in this page:

https://kitware.github.io/vtk-examples/site/Cxx/GeometricObjects/ColoredLines/

other examples without this function works fine.

I’ve tried include headers suggested, but still not work, here is the full error information:

It solved compiled with MSVC. Seems compiler issue
