Hi, I'm trying to add a configuration derive to Squid by modifying cf.data.pre My addition looks like this: NAME: scrly_internal_ip_address TYPE: string LOC: Config.scrly_internal_ip_address DEFAULT: none DOC_START DOC_END However, when I attempt to build Squid I get the following error: In file included from cache_cf.cc:3401:0: cf_parser.cci: In function ‘int parse_line(char*)’: cf_parser.cci:2645:30: error: ‘class SquidConfig’ has no member named ‘scrly_internal_ip_address’ Any ideas on what I'm doing wrong and how I could fix it ?
