clock_gettime() not implemented in OS X

[erthink]

Rhetorical question - does OSX conform to SUSv2 and/or POSIX.1-2001?

[erthink]

@BohuTANG, could you test the devel-branch right now?

Also, please take a look to https://github.com/pmwkaa/ioarena/issues/3

Now the issues are(devel branch):

Oh, yeah. I have never compiled it on a 32-bit platform. No problem, will fix when I get a free time.

@BohuTANG, I fixed the clang-warnings a few days ago. Please check devel-branch again.

[BohuTANG]

Hello, There still some issues  (devel):

@BohuTANG, done one more ;) Please try make -k to collect the all errors/warnings.

@leo-yuriev

--- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt -target_link_libraries(${ia_binary} ${ia_libraries} m rt pthread) +target_link_libraries(${ia_binary} ${ia_libraries} m)

with this fix it's ok to me on OSX now.

[erthink]

@BohuTANG , I generalize your patch through the use of cmake. Please verify and close this issue.

[BohuTANG]

@leo-yuriev Great work, it works on OSX now.

[erthink]

@BohuTANG , thank you.

Please, verify also the https://github.com/pmwkaa/ioarena/issues/3
