Compilation Issue on MacOS Sierra v10.12.6

[muthuswamy]

When I tried to compile on MacOS, I get the following: $make all /Applications/Xcode.app/Contents/Developer/usr/bin/make -C ../RedisModulesSDK/rmutil gcc -g -fPIC -O3 -std=gnu99 -Wall -Wno-unused-function -I../ -c -o periodic.o periodic.c periodic.c:34:5: warning: implicit declaration of function 'clock_gettime' is invalid in C99 [-Wimplicit-function-declaration] clock_gettime(CLOCK_REALTIME, &ts); ^ periodic.c:34:19: error: use of undeclared identifier 'CLOCK_REALTIME' clock_gettime(CLOCK_REALTIME, &ts); ^ 1 warning and 1 error generated. make[1]: [periodic.o] Error 1 make: [rmutil] Error 2

How can resolve the issue? Where should I declare CLOCK_REALTIME? The command, $uname -s returns the value as Darwin

Also, I am new to use of redis module. So, appreciate your time to resolve this issue. Thank you,

This is weird, it works on my mac:

Also with gcc-7:

I don't have access to Sierra machine at the moment, Try to reftech the submodules and use clang instead
