Hi Kurt, Andreas,
I ran into this issue today. When switching from stretch to buster I
noticed that gmsh couldn't read STEP files anymore. The following
error message appears:
Error : Gmsh requires OpenCASCADE to import shape
I've fixed the issue by building gmsh with the additional build
dependency libocct-data-exchange-dev. See patch 0001. I've also added
a small autopkgtest (patch 0002) using a STEP file that is part of the
source package.
Best, Joost
