Hi, I am facing problem while builing syslog-ng-2.1.3 on RHEL3 operating system. Configuration goes fine but it shows error while doing 'make'. Here is details of configuration option: champ@localhost syslog-ng-2.1.3]# ./configure --enable-static-linking --prefix=/opt/soe/local/syslog-ng-2.1.3 EVTLOG_CFLAGS="-I/opt/soe/local/syslog-ng-2.1.3/eventlog/include/eventlog" EVTLOG_LIBS="-L/opt/soe/local/syslog-ng-2.1.3/eventlog/lib" checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes . . . checking for EVTLOG... yes checking for LIBNET... yes checking whether to enable Sun STREAMS support... no checking whether to enable Sun door support... no checking whether to enable TCP wrapper support... yes checking whether to enable spoof source support... yes checking whether to enable IPv6 support... yes checking whether to enable SQL support... no checking for pkg-config...
