ld: Unsatisfied symbol "getopt_long" in file

I am compling from source code. I am getting the below error. I have tried multiple things but nothing has worked.

ld: Unsatisfied symbol "getopt_long" in file ./.libs/liboathtool_cmd.a[liboathtool_cmd_la-oathtool_cmd.o]

That's not very informative.

I know nothing, but isn't getopt_long() a GNU libc feature?
Presumably, one could extract some getopt_long()-containing C source
code from the glibc source collection, rather than trying to build/find
the whole thing.

I am sorry for the useless information I gave. I'll Describe my problem in Breif.

I am trying to compile oathtool from source code in HP-UX 11.31. While Compling I am getting the error ld: Unsatisfied symbol "getopt_long" in file. I am not trying to compile getopt_long.

Things to note -

I manually copy pasted the getopt.h from the web. As I couldn't find it in the HP-UX machine and had put it in the lib directory.

Things I tried -

Tried Hashing it out in the Makefile.

tried manually running it with aCC

aclocal autoheader autoconf autoreconf and none worked till now.

   You may need to. If it's not in the HP-UX C RTL, and you don't have
the GNU C RTL, then compiling the source seems to me like the thing to
do.

   That's a start. Keep going.

   I'd keep it separate from the standard HP-UX files. That may force
you to play with your compile (-I) and/or link (-L,-l) options, but I
wouldn't mess with the standard files.

   If the code wants getopt_long(), then you need to change the code, or
else give it a getopt_long(). On a GNU/Linux system, you'd have the GNU
C RTL (glibc), which should include it. On HP-UX, if it's not already
there, then you need to get it.

I am not a developer. I just downloaded the source code from the website and compiled the code. It would be helpful if you could help elobrate on the solution.

Edit - So, I did do a little digging and found that the Makefile was excuting the below command

./libtool --silent --tag=CC --mode=link gcc -std=gnu99 -g -O2 -o oathtool oathtool.o gl/libgnu.la liboathtool_cmd.la

and throwing the exact below error while make-"ing".

libtool: link: gcc -std=gnu99 -g -O2 -o .libs/oathtool oathtool.o -L../liboath/.libs -loath gl/.libs/libgnu.a ./.libs/liboathtool_cmd.a -Wl,+b -Wl,/usr/local/lib

   Complain to the people who provide this package?

   There's not much to elaborate. The program uses getopt_long(). If
that's not provided in the HP-UX run-time libraries, then you would need
to provide it yourself. You found getopt.h. I'd guess that something.c
with getopt_long() in it shouldn't be far away.

   Assuming that "the website" is http://www.nongnu.org/oath-toolkit/ ,
I didn't notice anything there about operating systems where the program
is expected to run, so they may assume that if GNU/Linux has it, then
everyone else must have it, too.

   Yes, that's where it would happen.

Yes. It would have to be ported. Or converted to use getopt(3).
