Those should be defined in libncurses, I think. Do you have the
ncurses5 library installed? It may be the linker is not finding the
libraries correctly (maybe use the --with-libs=/path/to/libdir). The
linker is often very limited in where it will look for thing by default,
hence all the -L/usr/X11R6/lib and similar flags. See other post as
well.

Hi gang,

Ok, I installed the libncurses 5.2 and it appears that they were already installed because modules that compiled before gave a error stating that "/usr/lib/libncurses.a is out of date; rerun ranlib(1)". After updating with ranlib the modules that worked before now work, however, I still get the errors with the above modules:

   /usr/bin/ld: Undefined symbols:
   _gtty
   _stty

Which leads me to believe that they must be defined somewhere else.... Where??

I would really like to figure this one out as it will fix 6 modules....

Thanks,

Well, not sure where those get defined, but I find "gtty" and "stty" in
libc.a. I couldn't find those symbols in libncurses.a, libcurses.a, or
libtermcap.a -- sorry for the red herring. You can use "nm
/path/to/staticlib.a | grep '<symbol>'" to hunt for where symbols are
defined. See if libc.a has 'stty' (it probably does). Are you using
the --with-USE_TERMIO directive? If not, maybe it's worth a try.
