Hi, has the fix been tested on Mac OS X?

When I try the example as given on the Wiki, I still get this reported error on 
Mac OS X 10.6.8

Apparently, my getopt version is not the enhanced one. This seems not to be 
recognized by the test in the beginning of shflags (line 136 of CL# 174).

GoetheMBP-2:~ andreas$ echo "\"`getopt --version`\""
" --"

Instead of "-- " as tested for by shflags.

GoetheMBP-2:~ andreas$ if [ "`getopt --version`" = '-- ' ]; then echo "Standard 
getopt"; fi
GoetheMBP-2:~ andreas$ if [ "`getopt --version`" = ' --' ]; then echo "Standard 
getopt"; fi
Standard getopt
GoetheMBP-2:~ andreas$

Sorry, wrote too soon... shflags sets correctly __FLAGS_GETOPT_VERS to 
__FLAGS_GETOPT_VERS_STD (0)

Final comment, for anyone having the same issue on Mac OS X, you can get the 
enhanced GNU getopt version via MacPorts (http://www.macports.org/).

  $ sudo port install getopt
  (after you installed MacPorts, see http://www.macports.org/install.php)

it's not fixed

@andreas: shFlags's plot being "Most shell scripts use getopt for flags 
processing, but the different versions of getopt on various OSes make writing 
portable shell scripts difficult. shFlags instead provides an API that doesn't 
change across shell and OS versions so the script writer can be confident that 
the script will work."

I don't see how installing getopt from MacPorts is satisfying. The whole point 
of shFlags is to avoid relying on a specific version of getopt...

Opening until there is a reasonable native fix for OS X.

Any word on this? Yosemite is about to launch and this is still an issue.

Hi, any news here? This still does not work on current MacOS (High Sierra) and it also does not work on my servers (DragonFlyBSD).

I'm using zsh.

@mahono everything seems to work if you run brew install gnu-getopt and brew link --force gnu-getopt the default getopt doesn't play nice with long flags and shFlags - something that should be fixed, but installing the better version always works. Not sure the equivalent commands for macports or anything else as I don't use them.
