Building iotivity on mac

Question

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?

Answer 1

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has added Mac buildability along with other build system reorgs - but I believe compared to iotivity that's rather out of date - however one could start picking fixes from there: https://github.com/OpenOCF/iochibity )
