Just downloaded 1.5.21 and libol 0.3.3. Libol compiles fine - installed into /usr/local/... I'm getting the following error with the syslog-ng compile... 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 main.o: In function `main_loop': /opt/source/syslog-ng/syslog-ng-1.5.21/src/main.c:225: undefined reference to `res_init' Anyone else seen this? Direction? TIA Andrew
