Using FreeCAD I'm sometimes getting wrong results exporting to Step file format. FreeCAD is built from GIT (latest version) using installed components on Fedora 35. Fedora (35, 36, 37) are using OpenCascade 7.5.0. Problem is fixed in a later version of OpenCascade (I tried the latest 7.6.3). I Reported the problem for Fedora 35 because that's what I'm still using. I know it's very close to end of life and I plan to upgrade soon. However fedora 36 and the coming 37 are also using same old version of OpenCascade. Problem report and discussion on the FreeCAD forum: https://forum.freecadweb.org/viewtopic.php?f=3&t=72858
I'm working on an update to the latest version for Rawhide, but pushing such a big change to released branches is more problematic. Is it OK to update to the latest 7.5.x since it appears to fix the problem?
Thanks Richard. I have a solution that will work until I upgrade to Fedora 37 (hopefully in two weeks). Going to 7.5.X vs 7.6.X? It a question of features vs risk (vs Fedora policies). I think providing the fixes from 7.5.X is good. Then plan to get 7.7 for the next Fedora release.

reopening, so we can track the rebase to a newer release
Bah... The github project and dev.opencascade.org are not in sync. They have different releases. The problem is that the dev site requires a login which is kind of a no-no. Because of that the sources cannot be directly downloaded by Fedora infra. I'm at camp this week but will try to figure out what to do when I'm back home.
First, please enjoy your vacation, Richard, this can wait :-) How about getting V7.7.0 tag from the https://git.dev.opencascade.org/gitweb/?p=occt.git, wouldn't that help?
First problem: CMake Error at adm/cmake/tbb.cmake:162 (find_package): Could not find a configuration file for package "TBB" that is compatible with requested version "2021.5". Looks like even rawhide has the 2020.3 version.

Maybe they don't rely on any new APIs (on Linux) ...
Richard, do you have some work-in-progress specfile for the opencascade update? I would take a look if the TBB version issue could be worked around.

There seems to be a bit of conversation on the tbb bug, hopefully they're making progress. Perhaps for now I should update to 7.5.3 or 7.6.3? It doesn't appear the the tbb version requirement was bumped until 7.7.0.
