Error Compiling

Hi, i got this error when compiling php-4.2.3 + apache-1.3.27 under RedHat7.2: It worked before with the same ./configure paremeters....any clue? This is the debug.log: CONFIGURE: './configure' '--with-apache=../apache_1.3.27' '--with-mysql' '--with-sybase-ct=/opt/sybase-11.9.2/' CC: gcc CFLAGS: -g -O2 CPPFLAGS: CXX: CXXFLAGS: INCLUDES: -I/src/apache_1.3.27/src/include -I/src/apache_1.3.27/src/os/unix -I$(top_builddir)/Zend -I/src/php-4.2.3/ext/mysql/libmysql LDFLAGS: LIBS: -lcrypt -lresolv -lm -ldl -lnsl -lresolv -lcrypt DLIBS: SAPI: apache PHP_RPATHS: uname -a: Linux ric2.xxx.xxxx.xxx 2.4.19 #1 SMP Wed Oct 16 09:58:48 ART 2002 i686 unknown gcc -o conftest -g -O2 conftest.c -lcrypt -lresolv -lm -ldl -lnsl -lresolv -lcrypt 1>&5 ---------------------------------- Thanks in advance Francisco
