OS: 4.1 w/GFX patches
Software: Sendmail 5.64 from uunet
I attempted to make sendmail, and ld reported the following undefined
symbols:
ld: Undefined symbol
_unsetenv
_res
Before I dig into this, has anyone else resolved these undefines?
Thanks for your help.

Sendmail ver: 5.64 from uunet
Sendmail 5.64 is now compiled on the Sun systems [thanks for all the
help!], but there seems to be a problem when another system tries to
make an SMTP connection to sendmail on the sun.
Here is a sample telnet connection which demonstrates the problem:
% telnet sun4 25
Connected to guava.
Escape character is '^]'.
220 guava.autosys.com Sendmail 5.64+/ease-smail2.5/evision: 2.5 ready ...
250 Hello [192.5.98.42], why do you call yourself dogwood.autosys.com?
I ran the server in dbx and it appears that the 'gethostbyaddr' call
is failing in daemon.c, specifically line 249. Here's the code
section:
(void) signal(SIGCHLD, SIG_DFL);
/* determine host name */
[ THIS NEXT CALL APPEARS TO BE FAILING, gethostbyaddr() ]
hp = gethostbyaddr((char *) &RealHostAddr.sin_addr,
\ sizeof RealHostAddr.sin_addr, AF_INET);
if (hp != NULL)
(void) strcpy(buf, hp->h_name);
else
{
extern char *inet_ntoa();
/* produce a dotted quad */
(void) sprintf(buf, "[%s]",
inet_ntoa(RealHostAddr.sin_addr)); [THIS GENERATES 192.5.98.42]
}
When gethostbyaddr() returns null, the RealHostAddr gets set to the IP
address of the client system. This gets caught later on and causes
problems.
Sendmail was compiled using the -lresolv library and the necessary
getenv/setenv routines from the sendmail/support directory.
I need help on this one real quick. Thanks everyone.. you've been
great.
