Update snap edge/beta to OCC 7.7.2

[luzpaz]

Per wwmayer OCC 7.7.0 compiles fine with latest FreeCAD HEAD. We should add it to snap edge in that case

you'll need to change this to V7_7_1_BF
https://github.com/FreeCAD/freecad-deps-core20-snap/blob/d58e75c254cb308d46dc522a6a3211767b092725/snap/snapcraft.yaml#L25

it's possible that you will need to move to core 22 also:

occt 7.7 requires tbb >=2021.5 which I doubt would be in ubuntu 20.04

You're right, @adrianinsaval. Do you know if I can keep things as they are for stable and change OCC and core 22 just for snap edge and snap beta builds?

  

[adrianinsaval]

I would expect yes, but I'm not all that familiar with how making snaps work

[adrianinsaval]

There's some bugs with occt 7.7.1 that I don't think we're going to fix before release, I'll move this out of the 0.21 project. Better to do this next cycle.

7.7.2 released: https://dev.opencascade.org/content/open-cascade-technology-772-maintenance-release

Are we not building Blobfish for the snaps? I should fix if not.

[adrianinsaval]

we are using blobfish: https://github.com/FreeCAD/freecad-deps-snap/blob/d58e75c254cb308d46dc522a6a3211767b092725/snap/snapcraft.yaml#L24-L25

[luzpaz]

has blobfish rebased his patches on 7.7.2 yet ?

[chennes]

I don't think so: the latest I see is 7.7.1BF
https://gitlab.com/blobfish/occt/-/tree/V7_7_1_BF?ref_type=heads

[adrianinsaval]

the blobfish patch set keeps growing but none of it is going upstream, should we worry about that? Can we do something to get those merged upstream?

[luzpaz]

Maybe we can forge a relationship with upstream (there is a gentleman that has represented OCC in previous FLOSS conferences) and have a (paid?) liason work to merge patches ?

[chennes]

We cannot "merge" his code upstream, he has not signed the OpenCASCADE developer agreement, and is not interested in doing so. His patches would have to be rewritten.

[adrianinsaval]

Ugh, I wish they would drop that silly requirement.
