1. failed log:

2. Mac OS Sierra (10.12) and above implement clock_gettime() and does not require emulation. However clock_nanosleep() is still not implemented in any version of macOS or OS X. please check : https://github.com/ChisholmKyle/PosixMachTiming

Good to know that macOS is not POSIX. Thanks for reporting. What to do about it?

[hawkinchina]

I just simply include the files in the project of https://github.com/ChisholmKyle/PosixMachTiming timing_mach.c timing_mach.h.

and modify qf_port.c in the directory of posix-qv

  // sleep without drifting till next_tick (absolute), see NOTE03
   // if (clock_nanosleep(CLOCK_MONOTONIC, TIMER_ABSTIME, &next_tick, NULL) == 0) // success?
        if (clock_nanosleep_abstime(&next_tick) == 0) // success?  modified by jack_he.
        {
            QF_onClockTick(); 
        }

and then it is ok.

The qpc and qpcpp POSIX ports have been adapted for APPLE. The changes have been checked into the qpc and qpcpp repos. With these changes, the examples should build and run on macOS. This includes the Spy build configurations. For example, here is the updated file qpc/ports/posix-qv/qf_port.c --MMS
