Hey all, I'm trying to compile squid 3.1.20 on a RHEL5 machine (running kernel 2.6.18-308) with --enable-linux-netfilter to add support for running as a transparent proxy. Also installed are libcap development files1.10-26 (i.e. /usr/include/sys/capability.h and /usr/include/linux/capability.h with libcap-devel). Unfortunately, when running configure the script is consistently throwing: configure: WARNING: Missing needed capabilities (libcap or libcap2) for TPROXY configure: WARNING: Linux Transparent Proxy support WILL NOT be enabled configure: WARNING: Reduced support to Interception Proxy configure: WARNING: Missing needed capabilities (libcap or libcap2) for TPROXY v2 configure: WARNING: Linux Transparent Proxy support WILL NOT be enabled This seems to be a pretty common problem people are running into, but the solution most people on the Internet present is to make sure libcap is installed. Could the configure script be looking in the wrong place for some reason? Full config flags are below ./configure \ --prefix=/opt/www/squid-3.1.20 \ --disable-dependency-tracking \ --enable-arp-acl \ --enable-follow-x-forwarded-for \ --enable-auth="basic,digest,ntlm,negotiate" \ --enable-basic-auth-helpers="LDAP,MSNT,NCSA,PAM,SMB,YP,getpwnam,multi-domain-NTLM,DB,POP3,squid_radius_auth" \ --enable-ntlm-auth-helpers="smb_lm,no_check,fakeauth" \ --enable-digest-auth-helpers="password,ldap,eDirectory" \ --enable-negotiate-auth-helpers="squid_kerb_auth" \ --enable-external-acl-helpers="ip_user,ldap_group,session,unix_group,wbinfo_group" \ --enable-cache-digests \ --enable-cachemgr-hostname=localhost \ --enable-delay-pools \ --enable-epoll \ --enable-icap-client \ --enable-ident-lookups \ --with-large-files \ --enable-referer-log \ --enable-removal-policies="heap,lru" \ --enable-snmp \ --enable-ssl \ --enable-storeio="aufs,diskd,ufs" \ --enable-useragent-log \ --enable-wccpv2 \ --enable-esi \ --with-aio \ --with-default-user="squid" \ --with-filedescriptors=16384 \ --with-dl \ --with-openssl \ --with-pthreads \ --enable-linux-netfilter Thanks for your time, David
