ld – Wading through Mac OS X linker hell

Intro

Friend: I tried looking at static linking in Mac OS X and it seems nearly impossible. Take a look at this http://stackoverflow.com/a/3801032

Me: I have no idea what that -static flag does, but I'm pretty sure that's not how you link to a library. Let me RTFM a bit.

# Info for potential OBS Python hackers!
# Tip 1 - Read the "OBS Studio Backend Design" documentation page. Read the documentation table of contents.
# Tip 2 - be sure to add obspython.py to your script path to enable completion.
# Tip 3 - Some of the Python API is generated at runtime, so it won't show up in obspython.py.

This was a huge hassle to figure out, so I wrote up a little guide in hopes that others would find it helpful:

How to convince macOS to do IPv6 DNS lookups when your only IPv6 address is via a VPN or tunnel of some sort

The Problem

macOS's domain name resolver will only return IPv6 addresses (from AAAA records) when it thinks that you have a valid routable IPv6 address. For physical interfaces like Ethernet or Wi-Fi it's enough to set or be assigned an IPv6 address, but for tunnels (such as those using utun interfaces) there are some extra annoying steps that need to be taken to convince the system that yes, you indeed have an IPv6 address, and yes, you'd like to get IPv6 addresses back for DNS lookups.

I use wg-quick to establish a WireGuard tunnel between my laptop and a Linode virtual server. WireGuard uses a utun user-space tunnel device to make the connection. Here's how that device gets configured:

# An overly complicated SIP config checker

# This is a technically interesting implementation because it does not rely on csrutil
# Instead it queries the kernel directly for the current configuration status
# This means, for example, in environments where SIP has been disabled and csrutil has
# been removed or modified (say, with DYLD_LIBRARY_PATH), as long as python can run you
# can still check status

# Additionally, checking the nvram csr-active-config setting isn't accurate now with
# 10.12.2+, since running "sudo csrutil clear" deletes the variable until reboot,
