Call to undefined function Ora_Logon

I am using php 5.0.4 on SuSE 9.3 with Apache 2.0.54 and Oracle 10.1.0.3. I configured and built php with this: ./configure --prefix=/usr/local/php-5.0.4 --with-apxs2=/usr/local/apache2/bin/apxs --enable-cli --enable-cgi --enable-short-tags --enable-calendar --enable-dba --enable-dio --enable-ftp --with-gd --with-gettext --with-mysql --with-mysql-sock=/var/lib/mysql/mysql.sock --with-oci8=/u01/app/oracle/product/10.1.0.3 --enable-sockets --with-zlib-dir When I execute phpinfo() it shows the OCI8 support is enabled. However, ora_logon, Ora_Login, OCILogOn all fail with the same error. I then saw a section in the documentation that says if you receive this error, configure with these two options: --with-oracle=DIR --with-oci8=DIR However, when I add the --with-oracle directive it fails: checking for Oracle-ORACLE support... yes checking Oracle Install-Dir... /u01/app/oracle/product/10.1.0.3 checking Oracle version... configure: error: Oracle needed libraries not found Anyone have any ideas? Thx, CC
