php3 and oracle9i client libraries doesn't compile

hello people, I'm using this command to configure php3 ./configure --with-apxs=/usr/local/apache/bin/apxs --with-config-file-path=/usr/local/lib --enable-versioning --enable-track-vars --with-oci8=/u01/app/oracle/product/9.2.0.4 --with-oracle=/u01/app/oracle/product/9.2.0.4 --enable-sigchild that works ok. But when I type make it eventually fails with this error: gcc -shared -o libphp3.so mod_php3.o libmodphp3-so.a -L/usr/local/lib -L/u01/app/oracle/product/9.2.0.4/lib -lclntsh -lpsa -lcore4 -lnlsrtl3 -lclntsh -ldl -lm -lpthread -lnsl -lirc -lgdbm -lpam -lm -ldl -lcrypt -lresolv -Wl,--version-script=/usr/php/php-3.0.18/php.map -Wl,-rpath /u01/app/oracle/product/9.2.0.4/lib /usr/bin/ld: cannot find -lpsa collect2: ld returned 1 exit status apxs:Break: Command failed with rc=1 make: *** [libphp3.so] Error 1 I don't understand enough about this compilation process to know what lpsa is and why it can't find it. Does anybody know how I can get php3 to work with oracle 9i client libraries? thanks in advance to anyone who can help. neil
