Hi everybody, Excuse me for my bad english... I've installed Red hat Linux 8.0, and php 4.2.2, apache 2.0.40 and postgresql are installed automatically. Apache and php runs very well (i created a file "test.php" with the instruction phpinfo() and the information appears very well when i load my page in my browser, in particular i see the configure command of php and -- with-apxs --with-pgsql=shared take part of it). In an other php file, i try to connect a postgres database with the command pg_connect. And it appears in my browser this error message: Fatal error: Call to undefined function: pg_connect() ... the file httpd.conf contents: LoadModule php4_module modules/libphp4.so the file php.ini contents: pgsql.allow_persistent= On what should i do? Thanks for any help Johann
