@diivious ->

This is not nearly production code, but I got it working on a mac. I'll slowly work on getting this up and running right over the next couple of weeks

@eqvinox -> The tar.gz has the data you wanted.

[eqvinox]

=> will fix the __attribute__((section())) bits as part of the logging foo (because that uses it too and needs more functionality on it)

[qlyoung]

libyang needs to be shipped in homebrew

[rzalamena]

Some Mac OS X related PRs for history completeness:

• lib: fix error on MacOS #6032
• lib: Only add custom entry point to libfrr on Linux #6034

Given the state of mac and some of the gcc'isms we use. I do not forsee this ever happening. Closing at the moment
