Hi, Thanks for the response. I added the ssl option but its still complaining at the same point. /bin/bash ../libtool --tag=CC --mode=link gcc -g -O2 -L. -L/usr/local/ssl/lib -o check_dummy check_dummy.o utils.o ../lib/libnagiosplug.a ../lib/libcoreutils.a -lsocket -lssl -lcrypto gcc -g -O2 -o check_dummy check_dummy.o utils.o -L/export/home/nagios/nagios-plugins-1.4.5/plugins -L/usr/local/ssl/lib ../lib/libnagiosplug.a ../lib/libcoreutils.a -lsocket -lssl -lcrypto if gcc -DLOCALEDIR=\"/export/home/nagios/share/locale\" -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../lib -I../intl -I/usr/include/pgsql -I/usr/local/ssl/include -I/usr/local/ssl/include -g -O2 -MT check_http.o -MD -MP -MF ".deps/check_http.Tpo" -c -o check_http.o check_http.c; \ then mv -f ".deps/check_http.Tpo" ".deps/check_http.Po"; else rm -f ".deps/check_http.Tpo"; exit 1; fi In file included from check_http.c:46: common.h:216: warning: static declaration of 'floorf' follows non-static declaration /bin/bash ../libtool --tag=CC --mode=link gcc -g -O2 -L. -L/usr/local/ssl/lib -o check_http check_http.o sslutils.o netutils.o utils.o ../lib/libnagiosplug.a ../lib/libcoreutils.a -lnsl -lsocket -lresolv -lsocket -lssl -lcrypto gcc -g -O2 -o check_http check_http.o sslutils.o netutils.o utils.o -L/export/home/nagios/nagios-plugins-1.4.5/plugins -L/usr/local/ssl/lib ../lib/libnagiosplug.a ../lib/libcoreutils.a -lnsl -lresolv -lsocket -lssl -lcrypto Undefined first referenced symbol in file OpenSSL_add_all_algorithms sslutils.o ld: fatal: Symbol referencing errors.

Try ./configure --with-openssl=/path/to/ssl or set the environment variable $LDFLAGS to "/path/to/ssl/lib" prior to running ./configure. If you don't need SSL at all, you could also disable it using "./configure --without-openssl".
