SUMMARY: referencing errors in curses.a compiling ntalk

Hi Sun-Managers,

many thanks to:

Pat Myrto <rwing!>
Casper Dik <>
Christian Masopust <>

who gave interesting suggestions, but I have not been able
to solve the problem. In my opinion, there are bugs in the
libcurses.a libraries; the two functions


seem to be incorrectly implemented in /usr/ccs/lib/libcurses.a.
Replacing -lcurses -ltermlib by the equivalent -ltermcap (as
Pat Myrto suggested) brought the same linker errors as before.

Even the function


, meant to replace the obsolete

gave the same linker errors as crmode().

The Berkeley Version of libcurses.a, /usr/ucblib/libcurses.a,
still gives the same fatal multiple definition error. Including
-lucb (as Casper Dik suggested) brought no different result either.

The only workaround to compile 'ntalk' seems to be to throw
both calls out of the sourcetext; the program then will work,
but has difficulties converting CRs to LFs.

Maybe I'm luckier next time,
