develop branch build issues with VTK-8.1.0 and QT-5.14.2 on Ubuntu22

[jameskress]

Describe the bug

VTK and QT on the develop branch do not build on a fresh Ubuntu 22 system with gcc 11.4.0

To Reproduce

Try to build visit with the build_visit script on a fresh Ubuntu 22.04 system

./build_visit --parallel --makeflags -j14 --system-python --conduit --vtk --qt --qwt --adios --advio --boost --conduit --gdal --glu --h5part --hdf5 --icet --llvm --netcdf --mfem --mesagl --szip --silo --zlib --mpich --vtkm --boxlib --pyside --build-mode release --mpich --prefix /home/kressjm/packages/visit-install

Additionally, I tried having visit build its own python, but this was causing lots of headaches too. Hence system python here.

Desktop

• OS and version: Ubuntu 22.04
• VisIt Version: develop branch

Additional context

I saw some commits for QT6, so I don't know what the plan is for supporting QT5 going forward. But a few additional patches in the build system will fix QT. Below are the problem files and the fixes.

For VTK the issue is mainly around and solvable via this issue: https://gitlab.kitware.com/vtk/vtk/-/issues/17670

I wonder if this is related? #18747

Maybe this will fix: #18642

Potentially related to the first issue. It does not look like the fixes for MacOS will resolve these issues here. But I could be wrong.

I finished the build by doing the changes listed above, moving down go gcc 9.5, and with this I was able to let visit build python as well.

./build_visit --parallel --makeflags -j14 --python --conduit --vtk --qt --qwt --adios --advio --boost --conduit --gdal --glu --h5part --hdf5 --icet --llvm --netcdf --mfem --mesagl --szip --silo --zlib --mpich --vtkm --boxlib --pyside --build-mode release --mpich --prefix /home/kressjm/packages/visit-install

Fixing the VTK issue can be accomplished with a couple different greps

grep -rl "  nullptr, // tp_print"  ./ | xargs sed -i 's|  nullptr, // tp_print|  0, // tp_print|g'

grep -rl "  nullptr,                               // tp_print"  ./ | xargs sed -i 's|  nullptr,                               // tp_print|  0, // tp_print|g'

I still think a few of these will be issues moving forward.

After installed visit 3.3 on my ubuntu22.04, it fail to launch the interface. How can I fix that?

[JustinPrivitera]

Can you run visit with debugging enabled and send us the logs? You can try visit -debug 5, which should produce a number of files ending in .vlog. If you could send us the .5.vlog files we could have a look and help diagnose your issue.

closing, b/c releases will now focus on VTK 9 + Qt6
