Panther DNS Issues

One annoying thing about Panther is the number of unix packages that will fail to compile, citing DNS related problems during the make.

e.g.

gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -Wall -c `test -f dns.c || echo './'`dns.c
dns.c:234: error: `PACKETSZ' undeclared here (not in a function)
dns.c: In function `dorequest':

The solution?

replacing any instance of

#include <arpa/nameser.h>

with

#include <arpa/nameser_compat.h>

and also adding -lresolv to the LIBS section in the Makefile

These steps have been tested to work with mtr, but would probably also work elsewhere.
