Meeting Notes

Slicer Preview Build Error Associated with Extensions

Attempts to resolve a build error on Linux for Slicer Preview extensions (linked to the upgraded build environment with Qt5 + AlmaLinux8 + GCC14) have been unsuccessful.

gmake[5]: *** read jobs pipe: Bad file descriptor.  Stop.

Transition to Slicer Qt6

  • Paraview builds successfully on Kitware’s new Windows server.
  • Slicer does not yet build on Windows with the new infrastructure due to the need to upgrade to Qt 6.
  • The upcoming Slicer 5.10 release will be the last version using Qt 5.

Markups

Feature Discussion:

  • Consider adding support for deleting markups from disk when they are deleted from the scene.

Undo/Redo Enhancements:

  • Explored improvements to the markups undo/redo mechanism.

  • Options include:

    • Automatically saving markups to disk
    • Using a history system
    • Leveraging vtkMRMLSequenceNode for versioning and rollback
