Panther DNS Issues
From Wikifications
(Redirected from Compiling software)
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': dns.c:817: error: `PACKETSZ' undeclared (first use in this function) dns.c:817: error: (Each undeclared identifier is reported only once dns.c:817: error: for each function it appears in.) dns.c:819: error: `QUERY' undeclared (first use in this function) dns.c:819: error: `C_IN' undeclared (first use in this function) dns.c:817: warning: unused variable `buf' dns.c: In function `resendrequest': dns.c:833: error: `T_A' undeclared (first use in this function) dns.c:840: error: `T_PTR' undeclared (first use in this function) dns.c: In function `parserespacket': dns.c:938: error: `NOERROR' undeclared (first use in this function) dns.c:965: error: `MAXDNAME' undeclared (first use in this function) dns.c:990: error: `C_IN' undeclared (first use in this function) dns.c:997: error: `T_PTR' undeclared (first use in this function) dns.c:1057: error: `T_CNAME' undeclared (first use in this function) dns.c:1064: error: `T_A' undeclared (first use in this function) dns.c:1140: error: `NXDOMAIN' undeclared (first use in this function) dns.c: In function `dns_ack': dns.c:1160: error: `PACKETSZ' undeclared (first use in this function) dns.c: In function `dns_events': dns.c:1215: error: `T_PTR' undeclared (first use in this function) dns.c: In function `dns_lookup2': dns.c:1277: error: `T_PTR' undeclared (first use in this function) /usr/include/ctype.h: At top level: dns.c:234: error: storage size of `resrecvbuf' isn't known make[2]: *** [dns.o] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2
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.
