I had never attempted building with the --disable-internal-dns option before. Today, in the hope of enabling cache_dns_program, I tried it with squid-3.2.0.15-20120218-r11508. It barfed building /usr/local/squid/libexec/dnsserver:

Same problem. ls -al /usr/lib/libresolv.dylib lrwxr-xr-x 1 root wheel 17 Aug 4 2007 /usr/lib/libresolv.dylib -> libresolv.9.dylib cat /usr/include/resolv.h ... #define res_init res_9_init ... nm /usr/lib/libresolv.dylib | grep res_9_init 9351e8d1 T _res_9_init After searching online, this appears to be an issue peculiar to Mac OS X 10.3 or 10.4. I'm on 10.4.11. I tried a variety of workarounds: 1. Changing Makefile's "LIBS = " to "LIBS = -lkvm -lm -lresolv -lz" 2. Changing Makefile's "LDFLAGS=" to "LDFLAGS=-lresolv" 3. "export LIBS=-lresolv" 4. "export LDFLAGS=-lresolv" The only option that worked gets squid compiling with --disable-internal-dns is #4. I'm curious why the other three weren't effective. -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de
