PHP4 Not Seeing PostgreSQL 7.2

Can someone please tell me what the hell I am doing wrong. (2 days of no success = very frustrated). PGSQL is up and running no problem. I start it with: postmaster -D /path/to/data/cluster -i & I can connect to the postgresql v.7.2.1 database from remote workstations and execute queries no problem. In my php code I have tried: dl("pgsql.so") even though there is no pgsql.so on the server. I have installed both Postgres7.2 and PHP4 from source. Where does pgsql.so come from? (PHP or Postgre compile?) Tried to copy the /lib/libpgsql.2.2.so into place and rename. PHP erros out that pgsql.so is not a valid PHP library. (Kind of suspected this would happen). Tried include("DB/pgsql.php") and this gives endless errors about class db_common can't inherit etc... Isn't there any clear cut examples or step-by-step how tos? What am I missing here? By the way, I have set the LD_LIBRARY_PATH and I have included /usr/local/pgsql/lib path in /etc/ld.so.conf. Compiled PHP4 as follows: ./configure --enable-track-vars --with-gettext --enable-force-cgi-redirect --with-apache=../apache_1.3.26 --without-mysql --with-pgsql=/usr/local/pgql PHP code is working with Apache because other things work. Just that pg_connect() is always 'unknown function'. Here is how apache was compiled: ./configure --enable-module=so --activate-module=src/modules/php4/libphp4.a --enable-module=php4 Suggestions and help are very greatly appreciated! Eric
