Lack of clock support, unable to compile on Mac 10.12.3

[matteodelv]

Hi everyone, I'd like to tell you about an error during compiling on Mac 10.12.3. Basically, I downloaded the git repo, updated submodules, did autoreconf and config without any problems. I used this command: CFLAGS="-O2 -march=native -std=gnu99" ./configure

And this is its output:

\ ------------------------------------------------------------------------ sgminer 5.5.5-gm-a \ ------------------------------------------------------------------------

Configuration Options Summary:

Use git version......: yes libcurl(GBT+getwork).: Enabled: -lcurl curses.TUI...........: FOUND: -lncurses OpenCL...............: FOUND. GPU mining support enabled ADL..................: SDK found, GPU monitoring support enabled

Compilation............: make (or gmake) CPPFLAGS.............: CFLAGS...............: -O2 -march=native -std=gnu99 LDFLAGS..............:
LDADD................: -ldl -lcurl submodules/jansson/src/.libs/libjansson.a -lpthread -framework OpenCL -lm

Installation...........: make install (as root if needed, with 'su' or 'sudo') prefix...............: /usr/local

The problem occurs when I issue make command... Even though there are some warnings about ADL or sgmins.c, I get the following error which causes the compilation to fail:

util.c:1005:11: warning: implicit declaration of function 'clock_nanosleep' is
      invalid in C99 [-Wimplicit-function-declaration]
    ret = clock_nanosleep(CLOCK_MONOTONIC, TIMER_ABSTIME, ts_end, NULL);
          ^
util.c:1005:44: error: use of undeclared identifier 'TIMER_ABSTIME'
    ret = clock_nanosleep(CLOCK_MONOTONIC, TIMER_ABSTIME, ts_end, NULL);
                                           ^

After some research online, it seems that TIMER_ABSTIME and clock_nanosleep are not supported on Mac OS but just on Linux. Some functions, like clock_gettime, have been introduced since Mac 10.12 (as stated in time.h). Is there a way to solve this and compile this version of sgminer on Mac OS? Someone advised to use Mach Time as a workaround but I really don't know how to deal with it. Hope someone could figure this out. Thanks for the help and for your work!

in util.c find CLOCK_MONOTONIC and change this first found line to #if defined(CLOCK_MONOTONIC) && !defined(__FreeBSD__) && !defined(__APPLE__) && !defined(WIN32)

I was able to pass that error using your suggestion but then I received:

If you remove ADL header files from ADL_SDK, reconfigure, and run make it will compile.
