Looks like the EFL port disagrees with this fix.  Out of curiosity, what port are you seeing this build warning on?

FYI, instead, I think the better fix is to do:
    dataLog("SourceID: “, iter->key, “\n”);

Dear Mark,

     I am using EFL port, in my local build machine i got these error, but i am usng g++-4.8, std=c++11, is it some thing do with setup?

Thanks

Probably something to do with your compiler/toolchain version or perhaps custom compiler flags that you are using (if any).  Anyway, try the dataLog() version I suggested on the EWS bots.  Every port should be happy with that.

Or ... it’s probably a 32-bit vs 64-bit issue.  But using dataLog() should take care of that.

This is wrong.  dataLog() doesn’t take a format string.  Instead, it should take a comma separated list or items to be printed.  The correct way to do this is:
    dataLog(“SourceID: “, iter->key, “\n”);
