Source: facet-analyser Followup-For: Bug #1040334 As far as I can tell facet-analyser does not actually need python3-paraview, except for two build-time tests (basicPluginTest01 pvsm2webgl.py, and basicPluginTest02 pvsm2x3d.py)
I believe there is no conflict between paraview-dev and libvtk9-dev themselves. Certainly there's no file conflict and both packages can be installed at the same time. The conflict is only in the python module vtkmodules (libvtk9-dev Depends: python3-vtk9 but paraview-dev does not depend on python3-paraview). If that's the case, then a workaround is to simply disable these two tests during build and drop the python3-paraview Build-Depends. It should be possible to run the test scripts at runtime (i.e. in debci). Likely not via cmake but invoked manually from debian/tests. It might be worth asking facet-analyser upstream how they deal with the issue. Debian did not invent the problem. paraview upstream resolutely refuses to align paraview with a released version of VTK, but ITK (libinsighttoolkit5-dev) uses VTK as released. So facet-analyser upstream must be facing the same problem. How do they handle it? Drew
