Hello! I want to compile a squid 3.1.12 in Debian Lenny but I don't know what packages I need. Please help me. Configure options: ./configure --prefix=/usr/local/squid/ --enable-removal-polices=heap,lru --enable-delay-pools --disable-wccp --disable-wccpv2 --disable-snmp --enable-arp-acl --disable-htcp --enable-default-err-language=Spanish --enable-err-languages='English Spanish' --disable-http-violations --enable-linux-netfilter --disable-ident-lookups --disable-internal-dns --enable-auth --enable-auth-basic --enable-auth-digest --enable-external-acl-helpers=ldap_group --disable-translation --with-default-user=squid --with-logdir=/var/log/squid/ --with-pidfile=/var/run/squid.pid --with-large-files --with-filedescriptors=8192 --sysconfdir=/etc/squid/ --disable-loadable-modules I have installed cpp4.3, gcc4.3, g++4.3 and binutils2.18 Configure step works fine but I have a lot of undefined references at make time Thanks!
