According to the docs, Mac should be supported but when attempting to build iotivity some headers are used that I think are posix specific.

➜ iotivity git:(master) ✗
I'm following the instructions at https://wiki.iotivity.org/macosx_build_instructions pointed to by https://wiki.iotivity.org/build_for_your_system
had a look but can't see any flags that'd enable mac support explicitly. Anyone know if this is actually supported and just been broken in recent commits? I building master checked out two days ago.
There is a windows-port branch but no mac named branches. remotes/origin/1.3-rel has the same issue.
Found this https://stackoverflow.com/a/24947106/400048 which lead me to my assertion about the posix specific headers being used.
So, anyone know if this can be built on mac and if so, how?
It's not an "officially supported" platform or target at this point, I gather its health was better in the past. Some people have had decent luck building for Mac, I have not. Changes to improve it will certainly considered, and there's an opening for a "Mac port maintainer" to make sure it doesn't rot again (and there's a github project which has added Mac buildability along with other build system reorgs - but I believe compared to iotivity that's rather out of date - however one could start picking fixes from there: https://github.com/OpenOCF/iochibity)
