AFAIK VTK is not tested with mingw
BUT Iâm able to build VTK 9.0.1 with Mingw64. 
@jschueller Do you have any insights here? I suspect the template export stuff isnât valid for MinGW.
I find code in file vtkImageStencilIterator.h
#ifndef vtkImageStencilIterator_cxx
#ifdef _MSC_VER
#pragma warning(push)
// The following is needed when the vtkImageStencilIterator template
// class is declared dllexport and is used within vtkImagingCore
#pragma warning(disable : 4910) // extern and dllexport incompatible
#endif
vtkExternTemplateMacro(extern template class VTKIMAGINGCORE_EXPORT vtkImageStencilIterator);
#ifdef _MSC_VER
#pragma warning(pop)
#endif
#endif
#endif
and found the macro in file vtkImageStencilIterator.cxx
#define vtkImageStencilIterator_cxx
I dont have any problems with 9.1.0 in release mode mode, maybe try that.
The vtkImageStencilIterator.h/.cxx code hasnât been touched for 5 years, so it definitely shouldnât be causing new problems in VTK 9.1. Are you sure that you havenât changed something in your build configuration?
@jschueller I will try that. and in debug mode, how handle âtoo many sections (78878)â ??
@jschueller
the result is same

anyone can help ?
maybe try to disable that module, see if there is a cmake option name morphological something
Building VTK9.3.0 with Mingw64 in Windows 10. Same error.
Building with CMake & Ninja under msys2/mingw64. It appears to be the final link that fails.
BTW â I had to add the following to CMakeLists.txt:
Line 9: add_compile_options(-Os -O3 -fcommon)
The -Os and -O3 optimizations were added to work around the error of âfile too bigâ.
The -fcommon was added to fix the multiple-defined errors during link due to the header files using old-style function definitions which is now deprecated without the -fcommon to fold identical definitions into a single definition.
Everything builds except for the final link, which fails with the same error of the original post regarding VTK9.1.0 using Mingw64 on Win10. I doubt I am the only person on the planet trying to build VTK for Windows 10 using msys2/Mingw.
I see the referenced cxx files and the header file which includes the iterator, but it appears that for some reason the template is not getting instantiated for this combination of parameters.
Ideas? Thanks in advance for any assistance.

I suspect we need to at least smoke test MinGW builds for release cycles. There are a number of issues cropping up recently (all template-related AFAIK).
