Here's a little problem I have. :) I am setting up an old box with Fedora Core 2 (yes, deprecated, I know) and Bind 8.1. The idea is, I want to setup my own network so I can play with DNS cache poisoning attack hence why I want to run old version of Bind. Running gcc 3.3.3, flex, and Bison installed. Here's the compile error I have: gcc -g -o nslookup main.o getinfo.o debug.o send.o skip.o list.o subr.o commands.o \ ../../lib/libbind.a ../../port/libport.a -lfl ../../lib/libbind.a(ns_print.o)(.text+0x1407): In function `__ns_sprintrrf': /root/src/lib/nameser/ns_print.c:454: undefined reference to `__b64_ntop' ../../lib/libbind.a(ns_print.o)(.text+0x1802):/root/src/lib/nameser/ns_print .c:515: undefined reference to `__b64_ntop' ../../lib/libbind.a(lcl_nw.o)(.text+0x17d): In function `nw_byaddr': /root/src/lib/irs/lcl_nw.c:152: undefined reference to `__bitncmp' collect2: ld returned 1 exit status make[2]: *** [nslookup] Error 1 make[2]: Leaving directory `/root/src/bin/nslookup' make[1]: *** [nslookup] Error 2 make[1]: Leaving directory `/root/src/bin' make: *** [all] Error 2 I am stumped, and my Google-foo failed me :| So, I am turning to my fellow listees to point me to the right direction ;) -- Registered Linux user no. 384430
