Fails to load libTopologicCore.0.0.0.dylib on MacOS

[p3palazzo]

Latest MacOS release (2022-03-07) + Blender 3.0

On trying to activate I get the following error:

Traceback (most recent call last):

Sadly I don’t have a Mac to test. As a possible workaround try copying the libTopologicCore.0.0.0.dylib out of the add-ons folder into /usr/lib

Thanks. Putting anything in the /usr/lib directory on a Mac requires disabling System Integrity Protection, which is very not good practice. I am trying a build from source using the Topologic repo and will let you know if it works.

Hi, did you succeed with building it from source? I tried but got ld: symbol(s) not found for architecture x86_64 error. But I also tried to build it using open cascade 7.5.1, which I later read is not supported?

I have not had the time to look into this for the past several months, but last I tried I was stumbling on building the proper versions of some of the requirements needed to build TopologicSverchok. Might try again later this year.
