Hello all,

The header “XdmfExport.h” is missing from the include subdirectory of VTK’s installation (vtkxdmf2/libsrc - I actually noticed that by chance in PV). The header is used by XdmfH5Driver.h and XdmfObject.h.

As a workaround I added the XdmfExport.h to the HEADERS section of vtk\_module\_add\_module at libsrc’s CMakeLists.txt

Is there any other way, more appropriate way, of exposing the Export header to the the vtk\_install/include subdir?

Thanks!

Yes, it should be installed. I’m including it in this MR which has other xdmf2 updates: [https://gitlab.kitware.com/vtk/vtk/-/merge\_requests/9082](https://gitlab.kitware.com/vtk/vtk/-/merge_requests/9082)
