For some reason we need to manually include the SystemConfiguration framework on macOS. I'm not sure why this is, as I don't think I changed any of the dependencies or the implementation.
Should we include this dependency in the roc cli linker flags for macos?

@Brendan Hansknecht I thought you mentioned you might look into this, but I've lost the conversation - and could have just imagined that.

Brendan Hansknecht (Jun 12 2024 at 05:23):Like the new socket library
Luke Boswell (Jun 12 2024 at 05:27):Interesting. I hadn't planned to change any dependencies... but I moved things around etc and that has generated a new cargo.lock file which has bumped the version on a lot of things.
Brendan Hansknecht (Jun 12 2024 at 05:29):Oh..... Hmm..... Not sure then
Brendan Hansknecht (Jun 12 2024 at 05:30):Weird for that to just get pulled in.... Feels like it's shouldnt be needed
Luke Boswell (Jun 12 2024 at 05:30):Ok, so it's the patch on reqwest from 0.11.20 -> 0.11.27 which adds the system-configuration dependency

Brendan Hansknecht (Jun 12 2024 at 05:37):Hmm...ok
Brendan Hansknecht (Jun 12 2024 at 05:37):Probably fine to just add
Luke Boswell (Jun 12 2024 at 05:37):I'll make a PR for roc then
Brendan Hansknecht (Jun 12 2024 at 05:37):This is why platforms really need to either control linker or just be surgical....one daj
