Hey, so libAlembic.so says it wants libImath-3_0.so.28, but the current version is libImath-3_1.so.29.2.0. I installed alembic from the arch community repo and it worked so I figure this is where the bug report should go?

Some info which may be relevant:

Hi @X-yl. That seems like alembic needs a rebuild, indeed.

I just queued it. If you are willing to test the rebuild version once it's done: You are going to get a signature error, since your local package in cache won't match the sync repo. You can just ignore that and redownload.

You can check if it has been build on the package status page as usual (see check date and build date once its done).

Yep, looks like it's fixed. Oddly though, now my lddtree output is different from what I get when I install from the arch repos.

This is what I get from installing community-x86-64-v3/alembic:

The libImath dependency is not present in the x86-64-v3 version. Not sure if that's a concern but blender does appear to work now.

That is intressting. I build alembic with -march=x86-64 -O2, -march=x86-64-v3 -O3 and -march=x86-64-v3 -O2.

All except the first show no linkage to libImath, even if cmake notes for all of them:

That is very weird. Not sure how to explain that, yet.

Well, since this is fixed I'll close this. Still interested to see why alembic does not link to libImath.
