I just downloaded syslog-ng-1.5.21 and libol 0.3.3 and tried to compile them on a Solaris 8 gcc 2.95 system. The build process stops with the following error: gcc -DHAVE_CONFIG_H -I. -I/export/home/jackson/syslog-ng-1.5.21/src -I. -g - O2 -Wall -I/export/home/jackson/libol-0.3.3/src -D_GNU_SOURCE -c getopt1.c gcc -g -O2 -Wall -I/export/home/jackson/libol-0.3.3/src -D_GNU_SOURCE -o syslo g-ng main.o sources.o center.o filters.o destinations.o log.o cfgfile.o cfg-gr ammar.o cfg-lex.o affile.o afsocket.o afunix.o afinet.o afinter.o afuser.o afst reams.o afprogram.o afremctrl.o nscache.o utils.o syslog-names.o getopt.o getop t1.o -lpthread -ldoor -lfl /export/home/jackson/libol-0.3.3/src/.libs/libol.a - lsocket -lnsl -lxnet Undefined first referenced symbol in file res_init main.o ld: fatal: Symbol referencing errors.

So I added -lresolv to the Makefile and everything compiled OK. Aaron Jackson
