[daurnimator]

It looks like apple finally caught up with the world and added CLOCK_REALTIME.
Try passing CFLAGS="-O2 -fPIC -DHAVE_DECL_CLOCK_REALTIME=1" to luarocks to override cqueues's feature guessing.

[chengkai-jia]

I got this issue when installing kong by homebrew.
I‘m not sure how to pass CFLAGS to work around it...

[SunshineYang]

try to execute export CPPFLAGS="-DCLOCK_MONOTONIC -DCLOCK_REALTIME" first . cqueues's feature guessing is not compatible on mac os
.

[vcunat]

The last pair of flags fixed compilation for "me" (NixPkgs, not Homebrew).

[daurnimator]

I think I understand the source of the issues now. In this commit I applied

-#define HAVE_DECL_CLOCK_REALTIME (defined CLOCK_REALTIME)
+#ifdef CLOCK_REALTIME
+#define HAVE_DECL_CLOCK_REALTIME 1
+#else
+#define HAVE_DECL_CLOCK_REALTIME 0
+#endif

As "expansion-to-defined" is not a well specified C behaviour. However, it used to get expanded in cqueues.c where the relevant header had already been included. vs now it gets expanded earlier.
