Sorry for the delay, I missed this issue.
samurai requires POSIX.1-2008 interfaces. You might need to set some feature test macros to get macOS to define the right functions.
The macOS continuous build does not show any problems (https://github.com/michaelforney/samurai/runs/648727481), so I'm not sure exactly why they are showing up on your system.
iirc macos 10.12 is when it got clock_gettime, so if your macos version is below that you'll need to update.
Ah, thanks for the info. @tfarina are you on an older version than 10.12?
Yeah, sorry about that. I didn't know the version requirement.
