When trying to run on macOS Big Sure version 11.4, getting the following error:

To Reproduce Steps to reproduce the behavior:

1. clone the repository
2. cd into the cloned folder
3. run make px4_sitl jmavsim

Expected behavior jmavsim should launch

Additional context

Looking at the time.h file mentioned in the error, i see it is explicitly marked as prohibited:

__OSX_AVAILABLE(10.12) __IOS_PROHIBITED
__TVOS_PROHIBITED __WATCHOS_PROHIBITED
int clock_settime(clockid_t __clock_id, const struct timespec *__tp);

It looks like it's trying to build for iphone?

 'clock_settime' is unavailable: not available on iOS

[omerts]

@dagar that is what is happening automatically when running make px4_sitl jmavsim on macOS

[dagar]

Do you have current PX4 master?

Did you run the macos setup script (./Tools/setup/macos.sh)? Does it complete successfully?

[omerts]

@dagar So sorry for late reply, I missed your response. Just ran macos.sh (didn't run it before because it was under Gazebo simulation), but unfortunately still the same error.
