VTK 9.1.0 on MSYS2 (Windows MinGW64): undefined reference to vtkSOADataArrayTemplate<int>::GetTypedComponent(int, int) const

    • Open Issue created by rockydut @rockydut

    When building VTK 9.1.0 I got an error about an undefined reference on MSYS2 (Windows with MinGW64). But I build VTK 9.0.1, mingw64 can compile fine.

        MinGW is not officially supported by VTK, but If you have a fix, we will integrate it. However, this should be closed. FYI @ben.boeckel

        Keeping the issue open for others to coordinate is fine.

        Regarding this issue, in VTK 9.0, extern template declarations were disabled in vtkCompiler.h:

        #if !defined(__MINGW32__)
#define VTK_USE_EXTERN_TEMPLATE
#endif

        But in VTK 9.1, they are not disabled (this changed in !8264 (merged)):

        #define VTK_USE_EXTERN_TEMPLATE

        However, we cannot go back to disabling extern templates, because there has been a bit of a template explosion in VTK 9.1 as compared to VTK 9.0 (see #18259 (closed), for example).

        So the only reasonable way forward is to find out why these "undefined references" occur for MinGW, but not for any other compilers. Is this due to a bug in MinGW? Or do we need to add something special for MinGW to the template declarations or definitions, or explicit instantiations? Hopefully someone who is familiar with MinGW can investigate.

        For vtkSOADataArrayTemplate<int>::GetTypedComponent(int, int) const in particular, the template definition is in vtkSOADataArrayTemplate.h:

        template <class T>
class VTKCOMMONCORE_EXPORT vtkSOADataArrayTemplate
  : public vtkGenericDataArray<vtkSOADataArrayTemplate<T>, T>
{
public:
...
  inline T GetTypedComponent(int i, int j) const
  {
    return this->Data[j]->GetBuffer()[i];
  }
...
}

        The extern declaration is also in vtkSOADataArrayTemplate.h:

        extern template class VTKCOMMONCORE_EXPORT vtkSOADataArrayTemplate<long>;

        And the explicit instantiation is in vtkSOADataArrayTemplateInstantiate_long.cxx (in the build tree):

        template class VTKCOMMONCORE_EXPORT vtkSOADataArrayTemplate<long>;

        Perhaps the undefined reference is somehow due to the fact that it's an inline method.

        The missing symbols are possibly related to the use of '-g' or compiling without optimization. See this discussion on discourse.
