I am using Libol 0.3.5 and syslog-ng 1.5.23. Libol installed without a problem. The make for syslog-ng terminates as follows: gcc -g -O2 -Wall -I/usr/local/include/libol -D_GNU_SOURCE -o syslog-ng main.o sources.o center.o filters.o destinations.o log.o cfgfile.o cfg-grammar.o cfg-lex.o affile.o afsocket.o afunix.o afinet.o afinter.o afuser.o afstreams.o afprogram.o afremctrl.o nscache.o utils.o syslog-names.o getopt.o getopt1.o -lpthread -ldoor -lfl /usr/local/lib/libol.a -lsocket -lnsl -lxnet Undefined first referenced symbol in file res_init main.o ld: fatal: Symbol referencing errors. No output written to syslog-ng collect2: ld returned 1 exit status *** Error code 1 make: Fatal error: Command failed for target `syslog-ng' Current working directory /usr/local/src/syslog-ng-1.5.23/src The ./configure step finds it OK. Where would I find it? TIA. Joe Haggerty
