vtkPythonSelector.h:38:8: error: marked ‘override’, but does not override

ParaView Support
1

Hi,

I am trying to build paraview 5.6 from the master branch. I get error while compiling vtkPVExtractSelection.cxx:

/ascldap/users/tesari/projects/paraview/ParaViewCore/ClientServerCore/Core/vtkPythonSelector.h:38:8: error: ‘void vtkPythonSelector::Execute(vtkDataObject*, vtkDataObject*)’ marked ‘override’, but does not override
void Execute(vtkDataObject* input, vtkDataObject* output) override;

Do I miss a flag or something? Any help is highly appreciated.

Attached is information about the master branch I use, cmake generator script, OS and compiler details, and the full error message.

Thanks,

Ted

I suspect that you’ve missed running git submodule update --recursive --init after updating to ParaView master and that your VTK checkout is out-of-date.

I thought that ‘submodule update’ is required when switching
branches. It works now, thanks a lot!

  Now I get a link time error: "undefined reference to

`__cxa_throw_bad_array_new_length’.

What do I miss here?

Thanks again,

Ted

Please ignore my previous mail.

  Linker was grabbing the system libstdc++.so, which is version

4.6. Linking with libstdc++.so from gcc6 fixed the problem.

Thanks,

Ted
