Hi,

Does mingw32 have getopt in its libraries? I am having trouble compiling
code using getopt with mingw32.
 Also, could not find getopt function call man page in the online tech
reference, any reason that its not there?

Thanks in advance.

yes, and no. The GNU getopt (as well as getopt_long) is part of the 
libiberty library, which should have been in the distribution (see the
<root>/lib directory), unless I missed it somehow. Unfortunately, the
getopt.h is not installed by default, which provides the prototypes and
some of the definitions needed for getopt_long. Let me know if you can't
find it in some other GNU package and I'll email it to you.

fyi, getopt is not ANSI, hence not guaranteed to be in an ANSI-only runtime;
it is however in the POSIX.1 specs, so most real systems provide it. My 
own code uses getopt that is built along with the package, so it's not an 
issue (and that's why I didn't miss the missing getopt prototype).

As a quick hack:

  extern int getopt(int argc, char * const argv[], const char *optstring);
  extern char *optarg;
  extern int optind, opterr, optopt;

  int main (int argc, char *argv[]) {
    /* use getopt */
  
  }

Now link -liberty as well.

  % cc -o getopt_test.exe getopt_test.c -liberty.

and see what happens.

I want to build a cross-compiler from Solaris to Win32 using Mingw32.
Can someone tell me the best way for that (any ideas, URL ...)

Thanks

getopt is not supported under the POSIX standard and has been deprecated on many 
(most? certainly IRIX and DECUnix) Unix platforms. Therefore it isn't support 
under cygwin32. It has been replaced by getopts. The functionality is the same 
though getopts is somewhat easier to use.

Hi all,
What, pray tell is mingw32?  How does it differ from cygwin32.com?
Thanks for any light on the subject.
